feat(buzz-agent): gate LLM tool calls on session/request_permission (#5712)
## Summary
buzz-agent now authorizes every LLM-issued MCP tool call through
`session/request_permission` before it executes, instead of running
tools unconditionally. The agent **always asks**; the client applies
`BUZZ_ACP_PERMISSION_POLICY` and answers. buzz-agent never reads the
policy — this keeps the policy decision on the client side, matching the
layering of the other ACP harnesses, and avoids duplicating policy logic
that would drift.
### Broker
A crate-local `PermissionBroker`
(`crates/buzz-agent/src/permission.rs`), owned by `App` for the
connection lifetime, owns the full request-correlation lifecycle:
- **Process-wide admission.** A global `Semaphore`
(`BUZZ_AGENT_MAX_PENDING_PERMISSIONS`, default 32, validated `>= 1`) is
acquired *before* any correlation entry is inserted. This is the
security bound: the per-turn tool semaphore is constructed fresh per
turn and `max_sessions` is unbounded by default, so neither bounds
simultaneously-outstanding asks process-wide.
- **Abort-safe cleanup.** A successful admission returns a
`PendingPermission` lease that owns the admission permit and the
correlation id. Its `Drop` synchronously removes the still-pending entry
and releases the slot, covering task abort/panic that bypasses the
normal `run_prompt` tail.
- **At-most-once resolution.** `deliver` claims (removes) the entry
*before* waking the waiter, so each id resolves once and a later lease
`Drop` is a no-op. Unknown/late ids are logged and dropped; only ids the
broker minted (`perm-<n>`) are recognized.
- **Single absolute deadline.** Admission, request enqueue, and response
wait all share one deadline (`BUZZ_AGENT_PERMISSION_TIMEOUT_SECS`,
default 330s, validated `>= 1`), so a saturated call cannot outlive one
timeout window even when a stalled writer blocks the enqueue.
Cancellation races inside every wait — resolution never depends on the
outer abort drain. A writer that dies mid-connection (stdout closed, or
a blocking write that only surfaces its error at flush) is
connection-fatal: it cancels all sessions, which resolves any ask
waiting on a reply that can never be written.
### Wire
`request_permission_params` (`crates/buzz-agent/src/wire.rs`) is
version-aware, keyed on the protocol version negotiated at `initialize`
and stored on `App` for the connection lifetime (never derived from a
later mutable session field). v2 nests the tool call under `subject:
{type: "tool_call", toolCall}` with top-level `title`/`options`; v1 uses
the legacy top-level `toolCall`. No hybrid shape. Both offered options
(`allow_once`, `reject_once`) carry `optionId == kind`, so the client's
`kind`-based selection and this side's `optionId`-based predicate agree
without a lookup table.
### Gate
In each spawned tool task (`crates/buzz-agent/src/agent.rs`) the
sequence is: acquire per-turn permit → argument-shape validation →
broker admission + request + wait → cancellation recheck →
`emit_in_progress` → `mcp.call`. Argument-shape validation is hoisted
out of `mcp.rs::do_call` into `validate_arg_shape` so a malformed
non-object argument is rejected locally without prompting for a call
that could never execute.
Authorization is fail-closed, stated once in `evaluate`: execute IFF
`outcome.outcome == "selected"` **and** the selected `optionId` equals
the offered allow option. Every other shape (reject, cancelled, JSON-RPC
error, malformed, unknown outcome, wrong/unknown option, timeout,
wire-channel closure) denies with a synthetic tool error, and the turn
continues.
### Scope
Only LLM-issued MCP calls are gated. The built-in `load_skill` tool and
`call_hooks` lifecycle calls (`_Stop`, `_PostCompact`) are exempt — they
are not model-issued. `readOnlyHint` is never treated as a security
boundary.
First cut ships `allow_once`/`reject_once` only; session-scoped grants
are deliberately out of scope.
### Related issue
Part of #4938. This PR and
[#5106](https://github.com/block/buzz/pull/5106) jointly implement the
feature: #5106 is the client-side policy engine and permission cards;
this PR is buzz-agent's asking side (`session/request_permission`).
Neither closes #4938 alone.

fix(agent): raise output limit and allow 3 recoveries (#5475)
## Summary Raise the built-in output and recovery defaults so long-running agents have more room to finish useful work instead of terminating after repeated 32,768-token reasoning-only responses. - Raise `BUZZ_AGENT_MAX_OUTPUT_TOKENS` from 32,768 to 65,536 - Raise the finite output-truncation recovery allowance from 2 to 3 via `BUZZ_AGENT_MAX_TOKEN_RECOVERIES`; `0` still disables recovery - Strengthen the recovery prompt so the model stops prolonged reasoning, uses tools immediately, and builds scripts or artifacts in small verifiable steps - Preserve the safety invariant that incomplete truncated tool calls are discarded and never executed - Keep proactive handoff independently at 90% of `BUZZ_AGENT_MAX_CONTEXT_TOKENS` (180,000 tokens with the 200,000 default), regardless of the output allowance - Add request-loop and configuration regressions for exact-N recovery, disabled recovery, successful tool-first recovery, discarded truncated calls, and finite round bounds `BUZZ_AGENT_MAX_OUTPUT_TOKENS` remains an explicit per-agent deployment setting. Operators should configure it at or below the served model's output limit; this PR does not perform live provider capability discovery or automatic clamping. **Risk:** Medium — this increases the default request size and permits one additional recovery attempt by default. Recovery remains finite and bounded by `BUZZ_AGENT_MAX_ROUNDS`. Deployments whose served model rejects 65,536 output tokens must set a lower per-agent value. Current output limits - model - output token max - DeepSeek V4 Flash - 384,000 tokens - Qwen 3.8 (Max) - 131,072 tokens - GLM 5.2 - 131,072 tokens - GPT 5.6 - 128,000 tokens - Claude Opus 5 - 128,000 tokens - Gemini 3.6 Flash - 65,536 tokens - Kimi K3 (Moonshot)- 131,072 tokens ### Related issue None found. Originating benchmark analysis: `buzz://message?channel=c3252dd2-0142-4e01-88c7-a2183c3960a5&id=91e991aab5fd49094583c3937477f6c12db57a41d86edf7fd4745d0d57d10017` ### Testing - `cargo fmt --all -- --check` - `cargo test -p buzz-agent` — 595 passed, 0 failed, 0 ignored at `bd6de557b367850f50325bafdd3c046131942bef` - `cargo clippy -p buzz-agent --all-targets -- -D warnings` - Previously failing `cancelled_turn_with_usage_emits_notification_before_response` passed alone and in the full rerun - Push hooks passed: organization guard, branch skew, Rust tests, and Desktop Tauri checks ### Update — 2026-08-11 Per review feedback, the recovery default is 3. The OpenRouter live `/models` output-cap discovery, cache, request clamp, and related tests/documentation were removed. Per-agent output configuration is now the sole output-cap mechanism. Proactive handoff and its pre-usage byte fallback now depend only on 90% of `BUZZ_AGENT_MAX_CONTEXT_TOKENS`; with the 200,000 default, the handoff threshold is 180,000 regardless of `BUZZ_AGENT_MAX_OUTPUT_TOKENS`. Generated with Brainy Bumble ### Targeted validation — 2026-08-11 Ran the exact PR binary once on each of the 11 benchmark tasks causally affected by the previous 32,768-token ceiling, using OpenRouter with `deepseek/deepseek-v4-flash-0731` pinned to Fireworks and maximum reasoning effort. Relay-429 collection failures were excluded and rerun at concurrency 2. - **6/11 passed:** `circuit-fibsqrt`, `feal-linear-cryptanalysis`, `model-extraction-relu-logits`, `path-tracing`, `schemelike-metacircular-eval`, and `sqlite-db-truncate` - **5/11 reached the benchmark deadline:** `adaptive-rejection-sampler`, `dna-assembly`, `path-tracing-reverse`, `regex-chess`, and `write-compressor` - `regex-chess` reached exactly 65,536 output tokens, triggered one output-limit recovery, and then reached the deadline. This directly confirms that the larger ceiling and recovery path were active, but not that recovery guarantees completion. For context, ten of these tasks were 0/5 in the historical baseline; `sqlite-db-truncate`, the clean control, was 4/5. This is targeted one-attempt-per-task validation rather than a statistically powered comparison. The result should not be attributed solely to the recovery default of 3: this PR also raises the output ceiling and strengthens recovery behavior, and OpenRouter routing conditions may differ from the historical direct-Fireworks runs.

feat(desktop): NIP-AM agent-usage backend — P2 emission/transport/archive + P4a aggregation/D6 (#4000)
## What Implements Phases 2 and 4a of the Usage v2 plan (plan events `d0268cd0`/`0e95b035`), extending the archive backend to emit, transport, archive, and aggregate both cache categories and billing identity fail-closed. ### P2 — emission, transport, archive **Tri-state accumulators** (`Unseen`/`Exact`/`Unknown`) for cache-read and cache-write in `buzz-agent` turn and session state. Absent field = Unknown (never zero) through the full pipeline. No `unwrap_or(0)` on the cache path. Both cache folds are gated on usage-bearing responses (same gate as the total-state and identity folds) — a response with no usage at all must not poison either accumulator. **Overflow-aware input token parsing and accumulation** — closed end-to-end from parse through wire to ACP: - `sum_usage()` returns `SumUsageResult` (`Exact(u64)` | `Overflow`) — checked arithmetic, never clamps. `anthropic_input_tokens()` returns `Option<SumUsageResult>` since it sums three fields (`input_tokens + cache_read_input_tokens + cache_creation_input_tokens`) that can collectively overflow. Single-field callers (`prompt_tokens`, `completion_tokens`, etc.) convert via `.into_exact()` — their single-field sums cannot overflow. - `LlmResponse.input_tokens_overflowed: bool` propagates the parse-layer signal into the run loop. When set, `input_tokens` is `None` (clamped value discarded), the context-gate baseline (`last_request_input_tokens`) is frozen at its prior reading, and `turn_input_tokens` is poisoned to `TurnIOState::Poisoned` before any emission — including mid-turn `emit_usage_update` calls. A dedicated enum on `LlmResponse.input_tokens` would ripple into ~20 existing test assertions on `r.input_tokens == Some(...)`; the bool flag confines the change to the two call sites that check it. - `TurnIOState` (`Unseen`/`Exact`/`Poisoned`) for input and output: per-round fold uses `checked_add`; overflow poisons permanently at turn and session level, no healing. Absence does not poison (pass-2-cleared contract unchanged). Wire emission omits `accumulatedInputTokens`/`accumulatedOutputTokens` when poisoned — never null, never `u64::MAX`. ACP treats absent = publisher-poisoned: `delta_reliable: false`, null turn fields, null cumulative for that category; session cumulative stays unknown for all subsequent turns once poisoned. **Conditional wire emission** for `accumulatedCachedInputTokens` and new `accumulatedCacheWriteTokens`: fields are omitted when the cumulative is Unseen or Unknown. ACP `_goose/unstable/session/update` contract documented next to the payload with tests for all absence/zero variants. **`PricingIdentity` stamping (publisher-side)**: - `pricing_authority()`: canonical parsed-URL endpoint comparison against the official allowlist — HTTPS only, exact allowlisted host (lookalike-safe), default port (omitted or explicit :443), required API base path, rejects userinfo/query/fragment/path-prefix lookalikes. - Model: the actually-requested `request_model` after mesh/auto resolution (not `effective_model_str`). - Turn discipline: identity retained only while ALL usage in the current turn carries one identical proven identity; any mismatch, unproven-usage-bearing response, or unpaired cumulative snapshot poisons to absent; a later matching notification does not heal a mixed turn. **ACP `UsageTracker` identity fold**: per-in-flight-turn tri-state identity accumulator replacing last-update-wins. Any absent identity on a token-advancing notification or exact mismatch poisons to absent; poison survives later updates; reset in `begin_turn()`/`take()`; reset also when a request fails (baseline cleared so preflight gate cannot stay frozen sub-threshold on retries). **M3 migration**: adds `turn_cache_write_tokens`, `cumulative_cache_write_tokens`, `pricing_authority`, `pricing_model`, `pricing_cache_class` to `agent_metric_index`. Additive, idempotent, guarded per-column by marker. M2 migration also guarded per-column (turn and cumulative cache-read columns checked and added independently; marker commits only after both are present). Fresh-DB schema includes all columns. **First-turn baselines**: `seed_zero_baseline` seeds `last_input: Some(0)`, `last_output: Some(0)`, `last_cached_input: Some(0)`, `last_cache_write: Some(0)`, and `last_total: Some(0)` — all have the known-zero-at-spawn argument. Absent fields from incoming snapshots still produce unknown (tri-state unchanged). Sessions buzz-acp did not spawn (no seed) remain fail-closed on turn one. **`ReportedUsage` TS mirror**: `cacheReadTokens`, `cacheWriteTokens`, `freshInputTokens` added to `tauriArchive.ts` as `UsageField` members, field-for-field with the Rust struct. ### P4a — aggregation layer **Extended S-1 ladder** to cache-read and cache-write via the same `ladder_token` path as the existing token fields. **`freshInputTokens` derivation**: checked arithmetic, fail-closed — absent cache fields produce Unknown (not zero), overflow and `cacheRead+cacheWrite > input` both produce `incomplete: true`. Aggregated as a `UsageField`. **D6 comparator**: `sort_value()` = provider total when known, else `input+output` when both known, else `None` (unknown-last). Replaces the prior total-only comparator for both agent-level and model-level sort. Ships a pinned test vector that the TS render layer (P5) must match. ## Test coverage - `buzz-agent`: 440 lib + 15 integration (golden_transcripts) — includes 13 new `cache_total_state_tests`; 14 new `turn_io_state_tests`; 3 new `sum_usage_*` tests (exact single-field, exact two-field, overflow signals correctly); 3 new `parse_anthropic_*` tests (overflow flag set + value cleared, normal sum no flag, absent usage no flag); end-to-end golden transcript drives real subprocess with Anthropic-shaped `input_tokens: u64::MAX, cache_read: 1` response and asserts `accumulatedInputTokens` absent from the emitted `usage_update` — no logic duplication; 3 wire pin tests; 4 `fold_pricing_identity_*` tests; `pricing_authority()` explicit-:443 acceptance - `buzz-acp`: 700 tests (691 lib + 9 integration) — 4 new usage tests (absent input → unreliable+null; absent output → unreliable+null; goose-shaped both present unchanged; poison mid-session); 3 ACP behavior tests; 7 pool lifecycle tests - Desktop (Rust): 2259+ tests — 14 new P4a pinned tests; 2 M3 round-trip tests; 1 serde key-shape test; 2 M2 partial-schema migration tests; first-turn cache round-trip test ## Related PRs - P1 NIP-AM spec: [#4632](https://github.com/block/buzz/pull/4632) - P3 pricing table: [#4629](https://github.com/block/buzz/pull/4629) - UI (P5): [#4001](https://github.com/block/buzz/pull/4001) --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Co-authored-by: npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> |

Recover from max-token response truncation (#5223)
## Summary - treat provider `max_tokens` as an interrupted assistant response and continue the same turn with actionable feedback - discard tool calls from truncated responses, including malformed partial arguments, so they are neither executed nor replayed with invalid tool-result pairing - bound recovery to two retries while preserving normal finite `max_rounds` accounting ## Verification - `cargo fmt --all -- --check` - `cargo test -p buzz-agent` (422 unit tests plus all package integration/doc suites passed) - `cargo clippy -p buzz-agent --all-targets -- -D warnings` ## Notes The pre-push repository-wide hook also ran. Its Rust tests passed (2,270 passed, 14 ignored), but its `buzz-db` unit-test build was blocked because local rustc 1.89 is below sqlx 0.9's rustc 1.94 requirement. The affected package suite above is green on the exact pushed commit.

fix(buzz-agent): Responses reasoning summary, Anthropic display:summarized, ACP v2 messageId (#5195)
Three pre-existing gaps in the buzz-agent observer feed fixed together
per Will's ruling ("all 3 in the current PR"):
1. **OpenAI/DBv2-GPT route** — `responses_body` never requested
`reasoning.summary`; GPT-family models billed thinking tokens but
returned `summary: []`.
2. **Anthropic/DBv2-Claude route** — `anthropic_thinking_config()` never
sent `thinking.display`; newest Claude models (Opus 5, Sonnet 5, Fable
5, Mythos 5, Opus 4.7/4.8, Mythos Preview) default to
`display:"omitted"`, returning thinking blocks with an empty `thinking`
field — observer rendered nothing.
3. **ACP v2 compliance** — buzz-agent negotiates ACP v2 but emitted
`agent_thought_chunk` and `agent_message_chunk` without `messageId`,
which ACP v2's `ContentChunk` requires (`messageId` + `content` both
required at schema head `d13d1baa`).
## Changes
**`crates/buzz-agent/src/config.rs`**
- New `ThinkingSummary` enum (`Auto`/`Concise`/`Detailed`) with
`BUZZ_AGENT_THINKING_SUMMARY` env var (default `Auto`); mirrors
`BUZZ_AGENT_THINKING_EFFORT` pattern
- `anthropic_thinking_config()` now emits `"display": "summarized"` in
both the adaptive shape and the manual-budget shape whenever thinking is
enabled
- Rewrote `is_adaptive_thinking_model` and `anthropic_thinking_config`
doc comments to match Anthropic's exact three-way per-model terminology
(doc:
https://platform.claude.com/docs/en/build-with-claude/thinking-troubleshooting#supported-models):
- Opus 4.6/4.7/4.8, Sonnet 4.6: **Off** — thinking OFF by default;
`type:"adaptive"` required to enable
- Opus 5, Sonnet 5: **On** — thinking on by default, can be disabled; we
still send `type:"adaptive"` to activate `output_config.effort`
- Fable 5, Mythos 5, Mythos Preview: **Always on** — thinking cannot be
disabled; we still send `type:"adaptive"` to activate
`output_config.effort`
**`crates/buzz-agent/src/llm.rs`**
- `responses_body` emits `reasoning.summary` alongside
`reasoning.effort` when effort is set (gated — no bare
`reasoning:{summary}` without effort)
- Covers both the pure-OpenAI Responses path and the DBv2 GPT-family
Responses path
**`crates/buzz-agent/src/agent.rs`**
- `agent_thought_chunk` carries `"messageId":
format!("{run_id}-thought-{round}")`
- `agent_message_chunk` carries `"messageId":
format!("{run_id}-message-{round}")`
- The two IDs are distinct (thought and assistant are two logical
messages per the ACP v2 Message ID RFD)
- `run_id` is a fresh random token per `session/prompt` invocation so
IDs are session-unique across multiple prompts
**`crates/buzz-agent/src/lib.rs`**
- `run_id` plumbed into `RunCtx` (was already generated in `run_prompt`,
just not threaded through)
**`crates/buzz-agent/tests/golden_transcripts.rs`**
- `test_acp_v2_chunks_carry_message_id` — negotiates v2, drives two
consecutive `session/prompt` calls, asserts: both chunk types carry
non-empty `messageId`; thought and message IDs are **distinct**; IDs do
**not** recur across the two prompts in the same ACP session
**`desktop/src-tauri/src/managed_agents/env_vars.rs`**
- `BUZZ_AGENT_THINKING_SUMMARY` added to `is_safe_to_reveal` allowlist
**`desktop/src-tauri/src/commands/agent_config_tests.rs`**
- Tests for `BUZZ_AGENT_THINKING_SUMMARY` allowlist entry
(case-insensitive)
## Tests added
- `parse_thinking_summary_round_trips_all_values`
- `parse_thinking_summary_unset_and_empty_yield_auto`
- `parse_thinking_summary_is_case_insensitive`
- `parse_thinking_summary_rejects_unknown_value`
- `thinking_summary_as_str_mapping`
- `responses_body_summary_present_iff_effort_set`
- `responses_body_emits_configured_summary_mode`
- `responses_body_concise_summary_mode`
- `anthropic_thinking_config_adaptive_emits_display_summarized`
- `anthropic_thinking_config_manual_budget_emits_display_summarized`
- `test_acp_v2_chunks_carry_message_id` (integration test — two-prompt
cross-session case)
## Notes
- **DBv2 gateway parity for `display`**: unverified — the DBv2 Claude
route proxies Anthropic Messages shape, but whether the gateway passes
`thinking.display` through is not confirmed. Flagged here rather than
blocking on it.
- buzz-acp and Desktop TS are unchanged — they already parse `messageId`
as optional and will pick it up from the wire automatically.
- Chat Completions and OpenRouter paths: untouched.

fix(buzz-agent): recover from context-window 400s instead of sticking (#4946)
Provider `context_length_exceeded` 400s permanently wedged agent sessions: the turn errored, the oversized history persisted in the in-memory session, and the usage baseline stayed frozen at the last successful sub-threshold reading (failed requests report no usage), so the preflight handoff gate never fired again — every later prompt failed identically until an agent restart. The byte-truncation fallback never intervened because it is a request-body limiter (`estimated_bytes`), not a context-window defence; at context-window scale it is a measured no-op. This adds the reactive recovery path: - **Typed classification.** `AgentError::LlmContextExceeded` is classified at both non-success provider terminals — the shared `post()` (Anthropic, OpenAI, Databricks) and `openrouter_post()` — on `status == 400` plus a context-window body match, so ordinary 400s stay terminal. - **Forced handoff.** A context-400 forces a summarize-handoff that bypasses `should_handoff()` and `BUZZ_AGENT_MAX_HANDOFFS`, bounded by its own per-turn budget (`MAX_CONTEXT_RECOVERIES_PER_RUN = 3`). - **Shrink ladder.** The summarize prompt budget halves from the observed rejected history size — not from `max_context_tokens`, the number the provider just contradicted — rung to rung, with a 4096-byte floor. A summarize call rejected for the same reason takes the next rung instead of re-sticking. At the floor (overflow dominated by unshrinkable frame: system prompt, tool schemas, live prompt) recovery is refused and the provider error surfaces clearly instead of self-healing. - **Baseline reset.** The stale usage baseline is cleared when a request fails, so the preflight gate cannot stay frozen sub-threshold on retries. Named behavior changes: 1. **Anthropic and OpenRouter errors now carry the `(model)` stamp.** Provider arms return their `Result` into the central error mapper instead of early-returning past it, making the code match its documented single-convergence contract at that mapper. 2. **`max_rounds` now counts completions the loop acts on.** A request rejected with a context-400 that is then successfully recovered refunds its round before the retry, paired 1:1 with a consumed recovery rung, so the round cap is neither weakened nor able to drop a recovered turn unanswered. Related: #4805 — the complementary proactive fix (per-session handoff-cap kill switch that let sessions grow to the provider wall). #4805 prevents reaching the wall; this PR recovers at it. --------- Co-authored-by: npub17jjz49l9jjmhhk7cac63j8yt9z555n9cw8vk7v5jz4vzw4ppld5qgj57cc <f4a42a97e594b77bdbd8ee35191c8b28a94a4cb871d96f32921558275421fb68@buzz.block.builderlab.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> |

fix(buzz-agent): scope handoff cap per turn, not per session lifetime (#4805)
`BUZZ_AGENT_MAX_HANDOFFS` compared against the session-cumulative `handoff_count` (persisted across prompts). After N handoffs a long-lived session hit the cap permanently: `maybe_handoff()` returned `Skipped` on every subsequent prompt, the 16 MiB byte-truncation fallback never bound before a 1M-token provider wall, and the session wedged on the first 400 with no recovery path. Thufir's session log shows 8 days of cap-forced truncation before the first `context_length_exceeded` 400. The fix replaces the session-level cap comparison with a local `handoff_attempts` counter constructed at the start of `run()` and passed into `maybe_handoff()`. The counter resets on every `session/prompt` turn so `BUZZ_AGENT_MAX_HANDOFFS` caps compaction loops within a single turn while allowing unbounded compactions across a session's lifetime. The session-cumulative `handoff_count` is retained for log context only and is not reset. Steer-driven rounds share the per-turn budget automatically since steers inject into the running `run()` loop, not a new call. - Move `handoff_attempts` increment to before `summarize()` so failed, empty, and cancelled summarize calls each consume one budget slot — the cap cannot be bypassed by a repeatedly-failing summarizer - Upgrade cap-forced `Skipped` from `INFO` to `WARN`; add structured fields for `session_id`, attempt count, projected tokens, and threshold so the cap→wall pairing is attributable per session - Document `max_handoffs` in `config.rs` as a per-`session/prompt`-turn bound - Three new behavioral regression tests: per-turn reset proven across two separate turns; within-turn cap proven via multi-round tool-call turn; failed summarize proven to burn the attempt budget Note: this is the proactive half of the context-window fix. The reactive `context_length_exceeded` 400 recovery path is owned by Sami's branch (`buzz-ctxfix-sami`, Tyler's crew); this PR is intended to land after that one. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Co-authored-by: npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> |

fix(agent): recover from unsupported image input instead of poisoning the turn (#4896)
## Problem
`buzz-dev-mcp` advertises `view_image` to every agent regardless of
whether the session's model accepts images. When a text-only model (e.g.
DeepSeek V4 Flash) takes the bait, the image lands in session history
and every subsequent LLM request 404s with `No endpoints found that
support image input`. The error was classified as `LlmModelNotFound` and
propagated fatally out of the turn loop — history stays poisoned,
buzz-acp retries the batch with exponential backoff, and the session
burns its entire clock doing no work. In a recent trial run, **all 57
trials that called `view_image` on a text-only model died this way; none
recovered.**
## Fix
Capability-gating the advertised tool isn't reliable — there is no
image-capability metadata at the agent layer across providers. Instead,
recover at the turn loop:
- **Typed error**: new `AgentError::UnsupportedImageInput`, classified
narrowly on the exact provider phrase `No endpoints found that support
image input` on both the generic 404 path and OpenRouter's 404 path.
Unknown-model 404s and OpenRouter parameter-routing 404s keep their
existing classifications. No deterministic retry.
- **In-turn recovery**: on this error, `RunCtx::run` strips every image
block from history — keeping the tool result (and therefore
tool-call/result pairing) intact — marks the result `is_error`, appends
actionable model-facing guidance ("The current model does not support
image input. The image was removed from conversation history so this
turn can continue. Use a text-based inspection tool…"), and continues
the same turn. Base64 never replays again.
- **Loop guard**: recovery only fires when at least one image was
removed; if the provider says "image" and history has none, the error
propagates as before.
## Tests
- Unit: phrase classification (typed, not retried; unknown-model 404
unaffected), idempotent image-to-error history mutation preserving call
IDs and text.
- End-to-end (`fake_llm.rs` + `fake_mcp.rs`): tool call → MCP image
result → 404 unsupported-image → same-turn recovery. Captured requests
prove round 2 carried the image, round 3 replays no image, carries the
guidance text, preserves pairing, and ends `end_turn`.
- Loop guard: typed unsupported-image error with **no** image in history
fails after exactly one provider request instead of spinning —
mutation-testing showed deleting the `removed == 0` guard survived the
suite, and `max_rounds` defaults to unlimited in production, so this
branch needed direct coverage.
Verified at `a210305019b33d5f56677b4c82bab79e4ac52d24`: `cargo test -p
buzz-agent` (full package, 381 unit + all integration suites) green;
`clippy --all-targets -D warnings` green; `fmt --check` green; pre-push
hooks (rust-tests, desktop-tauri-checks, branch-skew) green.
**Scope of the classification guarantee**: the classifier runs in the
shared `post()` (which Anthropic and OpenAI paths route through) and in
`openrouter_post()` — i.e., every 404 path in `llm.rs`. It only runs on
404 responses; providers that reject images with a different status
(e.g. a 400) are out of scope for this PR — see the review-comment
discussion for why broadening the phrase list alone would not cover
them.

fix: reauthenticate databricks model discovery (#4008)
## Summary - preserve Databricks catalog 401 responses as authentication failures and retry discovery exactly once after silently refreshing the rejected bearer - preserve runtime OAuth recovery: when discovery has no usable OAuth credential, `session/new` succeeds with only the trimmed configured model so the first `session/prompt` can run the existing browser PKCE flow - reject a rejected configured `DATABRICKS_TOKEN` with actionable, non-interactive guidance; static credentials cannot recover through PKCE - use the configured-model fallback for non-auth discovery failures without caching failed or fallback catalogs, so later sessions retry discovery - keep known Databricks v2 models only for authenticated empty-catalog responses and mark their provenance - resolve discovery before MCP spawn or session registration, preventing failed discovery from leaking resources or consuming session capacity - permit serialized interactive PKCE only from the explicit saved-agent model picker; passive draft discovery never opens a browser ## Runtime flow 1. OAuth discovery attempts cached credentials and silent refresh without opening a browser. 2. If no usable OAuth bearer exists, `session/new` advertises only the configured model and succeeds. 3. The first `session/prompt` uses `TokenSource::bearer()`, which may launch browser PKCE. 4. A later session retries discovery and caches only the authenticated catalog. ## Regression coverage - rejected-but-locally-fresh OAuth bearer performs one refresh and one catalog retry - OAuth mode with no cached token allows `session/new` and returns exactly the trimmed configured model - the OAuth fallback is not cached; a later authenticated session retries discovery and caches the returned catalog - rejected static tokens still reject `session/new` - failed discovery does not consume the sole session slot or spawn the supplied MCP process - Desktop interactive/passive auth intent, static-token redaction, and authenticated empty-catalog provenance ## Verification - `cargo test -p buzz-agent` - `cargo test --manifest-path desktop/src-tauri/Cargo.toml --lib commands::agent_models` - `cargo clippy --manifest-path desktop/src-tauri/Cargo.toml --all-targets -- -D warnings` - `cargo fmt --all -- --check` - `git diff --check` - full pre-push hooks ## Review Adversarial review found and drove fixes for session/MCP resource leakage, duplicate concurrent PKCE flows, sensitive error propagation, incorrect 403 reauthentication, missing discovery-level coverage, passive browser launch, and the Desktop file-size ratchet. The final follow-up preserves the existing prompt-time OAuth flow while retaining static-token rejection and pre-allocation discovery ordering. --------- Signed-off-by: npub1dccv64krpcpse5cmkzfeh998cftungyatw3djt8jwdw6g43f7fyqzzmrf7 <6e30cd56c30e030cd31bb0939b94a7c257c9a09d5ba2d92cf2735da45629f248@buzz.block.builderlab.xyz> Co-authored-by: npub1dccv64krpcpse5cmkzfeh998cftungyatw3djt8jwdw6g43f7fyqzzmrf7 <6e30cd56c30e030cd31bb0939b94a7c257c9a09d5ba2d92cf2735da45629f248@buzz.block.builderlab.xyz> |

fix: report agent usage per provider round, not once per turn (#4545)
## The bug buzz-agent emitted its `usage_update` notification in exactly one place: after `ctx.run()` returned. Until that moment a turn's token counters lived only in the prompt task's stack frame. **A turn killed mid-flight reported nothing at all** — the provider had already billed every round it completed, and no consumer ever saw any of it. That is not a corner case for anything that ends a turn on a clock. It is the normal case for a long-horizon benchmark run that relaunches its agent between phases. ## How big Measured against a provider's own billing ledger over one run's window: | | provider ledger | what we recorded | |---|---|---| | the relaunched lead seat | $485 / 348M tok | $98.99 / 90.3M tok | | the two seats that were not relaunched | $29.90 / 856M | $25.81 / 765M — reconciles | 97% of that run's usage rows came back all zeros, against 1–4% for comparable runs that never relaunch. In one 450-phase trial exactly 7 phases recorded any usage — and each of those carries 177k–437k input tokens, a whole session's worth landing in the one phase that happened to end gracefully. Worth being precise about what was *not* wrong, since both were plausible and both were checked: - **Not pricing.** The rates were verified against the provider's endpoints API and match what we charge. - **Not a truncation bug.** The usage files were intact and internally consistent. The tokens were never captured in the first place. ## The fix The run loop now emits a session-cumulative `usage_update` after every usage-bearing provider response, so an interrupted turn has reported everything but its single in-flight request. - **Emitting more than once per turn is already part of the contract.** buzz-acp's `UsageTracker` advances its committed baseline only at publish time, and goose behaves the same way — which is why the tracker was written to tolerate it. - **The turn-start session baseline is snapshotted into `RunCtx`** so the mid-turn figure stays *session*-cumulative. A turn-local number would be discarded by a high-water-mark consumer and lose the turn entirely; there is a test for exactly that. - **Snapshot by value, not a session handle.** The loop reports once per round, and taking the sessions lock on each would serialise concurrent sessions behind one another's provider round-trips. Nothing else advances those counters while the turn holds `busy`, so it cannot go stale. - **One shared `wire::usage_update_payload`** for both call sites, so the mid-turn and end-of-turn shapes cannot drift. A drift there would present as tokens silently vanishing, which is the failure this reporting exists to prevent. ## Why not a SIGTERM handler That was the obvious shape and it does not work. At signal time the counters are not sitting anywhere a handler could reach — they are in the turn's stack frame, and the value the handler would need has not been folded into the session yet. Making usage durable *during* the turn is what actually fixes it; once it is, a handler adds nothing beyond the in-flight request, whose cost is unknown until its response lands. ## Tests - `usage_is_reported_after_each_round_not_only_at_turn_end` — two rounds; asserts the **first** notification carries round 1's counts alone, proving it went out before round 2 returned. - `mid_turn_usage_includes_earlier_turns` — a mid-turn report must be session-cumulative, not turn-local. buzz-agent 18/18 on the `fake_llm` suite, 382 unit. `cargo fmt` / `clippy` / `cargo check --workspace --all-targets` clean. ## Scope Agent-side only, against `main`. The matching harness change — settling usage on the timeout path, which was skipped on the reasoning that an incomplete turn has nothing to flush — is **#4553**, against the benchmark branch, since that harness does not exist on `main`. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Signed-off-by: Atish Patel <atish@squareup.com> Co-authored-by: Claude Code <noreply@anthropic.com> |

feat(agent): optional reply guard reminds a silent turn to publish (#3763)
## Why
A Buzz agent's assistant text and reasoning are never shown to anyone —
only what it posts through the CLI. A turn that runs fifteen tool calls
and never publishes is a silent failure: the requester waits on a result
that was produced and thrown away.
This adds an optional reminder at the end-of-turn gate, off by default.
Tyler asked for it in buzz-mesh; plan iterated to **9.5/10 with @Wren**
(Minimalness 9.7, Elegance 9.5, Correctness 9.3).
## What
`BUZZ_AGENT_REQUIRE_REPLY=1` (default off, per-agent opt-in). A turn
about to end with no recognized attempt to post gets a reminder and is
rerolled. **At most two, then the turn ends regardless** — the guard
catches accidental omission, it does not compel speech. The reminder
text explicitly licenses silence so it cannot fight the base prompt's
"silence is usually correct."
**This is not a new MCP hook.** `RunCtx::run` *is* the turn, so the two
per-turn locals need no plumbing, and every tool call already passes
through it with arguments visible. The objection is appended at the
existing `_Stop` gate and rides `push_hook_outputs_as_tool_results`, so
the model receives it as a lower-trust tool result with `{hook, server,
text}` attribution. No new trust path, no new lifecycle event, no
dev-mcp or CLI protocol change.
Earlier revisions of this plan needed four crates (a `_UserPromptSubmit`
hook, a marker file, a `buzz-cli` change, dev-mcp state). Tyler pointed
out the agent already knows both facts; that deleted all of it. Net
runtime change is ~35 lines in `agent.rs` + ~4 in `config.rs`.
### Recognition contract
A registered non-hook tool whose qualified name ends in `__shell`, whose
`command` argument contains `messages send` or `reactions add`.
- **The `__` separator is exact, not approximate.** Given `has()` +
`!is_hook()`, `ends_with("__shell")` is *provably equivalent* to a bare
name of `shell`: registration forbids `__` in server and bare names
(`mcp.rs:227,268`) and qnames are `{server}__{bare}`, so a trailing
`__shell` could only straddle the separator if the bare name began with
`_` — which `is_hook` excludes. Without the separator, `powershell` and
`noshell` would match.
- **Reads the structured `command` field**, not serialized arguments, so
a `description` that quotes a send cannot disarm the guard, and a
non-string `command` is rejected rather than coerced.
- **Detects an attempt, not a successful publish.** A failed send
already returns non-zero exit and error JSON — louder than this
reminder. The variable is named `buzz_reply_call_seen` so the code can't
pretend otherwise.
- **Checked after the per-turn tool-call cap**, since a discarded call
never ran.
- `messages send` also covers `messages send-diff`. Reactions count
because the base prompt directs agents to react rather than post a bare
acknowledgement.
**Known limits, both deliberate and documented:** a command assembled at
runtime (`$CMD`) or hidden in a wrapper script is missed; text that
merely quotes a send (`echo "buzz messages send"`) matches. Missing a
real post is the expensive direction and substring matching is the
forgiving one there. Neither edge is pinned by a test, so the matcher
stays free to improve.
### Budget
Reminders share `BUZZ_AGENT_STOP_MAX_REJECTIONS`, the existing outer cap
on every end-turn objection. Default 3 fits both; at 1 only one fits; at
0 the guard is off with the hooks. A round carrying both a hook
objection and a reminder costs one rejection and delivers both texts. An
independent budget would either violate that bound or need a second
arbitration rule.
## Prior art
- **#3467** (closed) built the same detector one layer up in `buzz-acp`
for a different remedy. None of its symbols are on main — this borrows
its permission to be coarse, but reads structured data that ACP didn't
have.
- **#3648** (open) detects turns with *no output at all*; a turn with
fifteen tool calls and no post counts as output there, so it does not
cover this case.
- **#3741** (merged) is mesh-only.
## Testing
**14 new tests.** 4 unit tests on the matcher; 10 integration tests
through the ACP wire harness: off by default, `=0` still off, opted-in
silent → exactly 2 reminders then `end_turn`, registered `fake__shell`
send → 0 reminders, hallucinated `fake__shell` → still reminded, publish
call truncated past the 64-call cap → still reminded, budget 1 → 1
reminder, budget 0 → off, combined `_Stop` hook objection + reminder →
one round both texts and after 2 reminders the hook objection continues
alone, unparseable `=true` → startup error naming the key.
**10 mutation checks, each breaking a specific named test** — neutralize
the nag cap, stop sharing the budget, neutralize `buzz_reply_call_seen`,
drop `has`/`is_hook`, ignore the flag, drop the `__`, drop `reactions
add`, read serialized args, move detection before truncation.
`tests/bin/fake_mcp.rs` gains `FAKE_MCP_SHELL_TOOL=1`: it previously
exposed no tool with a bare name of `shell`, so the satisfied-guard path
was untestable.
Full `cargo test -p buzz-agent` green at 9e0ae1f04; clippy `-D warnings`
and `cargo fmt --check` clean.
**Unrelated flake found:**
`cancelled_turn_with_usage_emits_notification_before_response`
(`tests/fake_llm.rs`) is timing-sensitive. Under 10 loaded cores it
fails **2/20 on this branch and 1/20 at unmodified
`origin/main@02be413b8`** — pre-existing, not caused by this change
(which is inert without the env var). Flagging so it isn't misattributed
to the next PR that's open when CI hits it.
## Docs
`crates/buzz-agent/README.md` is the primary home (env var, recognition
contract, limits, budget interaction). `docs/MCP_DRIVEN_HOOKS.md` gets a
short cross-reference explaining this is *not* a hook — otherwise
readers hunt for a `_ReplyGuard` tool that doesn't exist.

feat(agent,acp): wire provider total_tokens through NIP-AM publish chain (#3593)
## What Wires genuine provider-reported `total_tokens` through the full buzz-agent → buzz-acp publish chain so kind-44200 events carry real per-turn and cumulative totals for OpenAI-backed models, while preserving all existing behaviour for Anthropic and external harnesses (goose, claude-code). ## Why Live prod data showed 0 of 1,934 archived reports carry `totalTokens`. Both hardcoded `total_tokens: None` in `pool.rs` and the absent field in `buzz-agent`'s parser are root causes. This is the backend half of a two-track fix; the display-fallback half lands in [#2035](https://github.com/block/buzz/pull/2035). ## Changes **`crates/buzz-agent/src/types.rs`** - Added `total_tokens: Option<u64>` to `LlmResponse` with an explicit doc comment that NIP-AM forbids deriving it. - Added `TurnTotalState` enum (`Unseen | Exact(u64) | Unknown`) with `fold()` and `exact_value()` — the tri-state accumulator that distinguishes not-yet-observed from permanently poisoned. **`crates/buzz-agent/src/llm.rs`** - `parse_responses` and `parse_openai`: read `usage.total_tokens` from OpenAI Chat Completions (including Databricks routes) and the Responses API via `sum_usage`. - Anthropic: explicit `total_tokens: None` — no genuine total available; NIP-AM forbids summing categories. **`crates/buzz-agent/src/agent.rs`** - Added `turn_total_state: &'a mut TurnTotalState` to `RunCtx`. - Fold `response.total_tokens` into the accumulator after each usage-bearing response; non-usage-bearing responses (keepalive/stream frames) do not poison. **`crates/buzz-agent/src/lib.rs`** - Added `accumulated_total_state: TurnTotalState` to `Session` (default `Unseen`). - Per-turn state passed to `RunCtx`, folded into session cumulative after each turn. - Emits `accumulatedTotalTokens` in `usage_update` only when cumulative is `Exact(n)`. **`crates/buzz-acp/src/usage.rs`** - Added `accumulated_total_tokens: Option<u64>` (serde default) to `UsageUpdatePayload` — optional for goose compat. - Added `last_total: Option<u64>` to `SessionState`. - Added `turn_total_tokens` and `cumulative_total_tokens` to `TurnUsage` (field-local — never affect `delta_reliable`). - Derive turn-total delta only when prev and current are both `Some` and monotonic; absence, decrease, or no baseline leaves only the total delta null without touching input/output reliability. **`crates/buzz-acp/src/pool.rs`** - Replaced both hardcoded `total_tokens: None` in `publish_agent_turn_metric` with `usage.turn_total_tokens` and `usage.cumulative_total_tokens`. ## Tests 20 new tests across the four touched files: | File | Tests | |------|-------| | `types.rs` | `TurnTotalState` fold, accumulation, exact_value, default (7 tests) | | `llm.rs` | Chat present/absent, Responses present/absent, Anthropic always-None (5 tests) | | `usage.rs` | First turn no baseline, second-turn delta, cumulative decrease (field-local), current absent, goose-shaped deserialization, baseline absent (6 tests) | | `pool.rs` | Exact turn+cumulative mapping, null totals never derived (2 tests) | `cargo test -p buzz-acp -p buzz-agent` — all passing, 0 failures. ## Scope Boundary: `crates/buzz-agent/**` + `crates/buzz-acp/**` only.
