From 2e595501542a59d6c314db60b53b139aba984385 Mon Sep 17 00:00:00 2001 From: Robert Gering Date: Thu, 6 Aug 2026 15:35:31 +0200 Subject: [PATCH 1/9] Pass the external review prompt out-of-band (swarm 0.8.0) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The prompt travelled as one argv word, so exec's MAX_ARG_STRLEN (128 KiB on Linux) was the binding limit and forced a 120 KiB cap. Above it the skill set EXTERNALS_OVERSIZE and dropped EVERY external voice — the same damage as a backend timeout, from a limit that was never inherent to the CLIs. Neither CLI needs the prompt on argv: codex reads it from stdin (`-- -`), grok takes `--prompt-file`. The adapter now normalizes every input form to one file and hands over the PATH, so the diff never enters a shell variable either. - Cap now bounds model context, not exec: SWARM_MAX_PROMPT_BYTES (default 512 KiB). Adapter and the skill's oversize guard read the same env knob with the same default, so an override reaches the externals instead of being short-circuited by a skip that never heard about it. - Temp prompts are chmod 600 before content lands and removed by the EXIT trap on every path; a caller-owned --prompt-file is never mutated, so concurrent per-cluster voices sharing one prompt file cannot corrupt each other. - grok's --prompt-file is preflighted (stubbable, so the argv tests stay hermetic) with an upgrade error — never a silent fallback to --single, which would reinstate the wall as a mystery failure on big diffs. - test_sandbox_deny.py pins the transport itself (regressions are silent: only large diffs would start failing); test_lens_sync.py pins the two cap defaults together and keeps the 4 KiB --lens-instr headroom covered. Verified end-to-end at 164 KiB through both backends.

Run the workflow From d24a99ba2cb624ab68771489264c7ccdb7487770 Mon Sep 17 00:00:00 2001 From: Robert Gering Date: Tue, 11 Aug 2026 15:50:28 +0200 Subject: [PATCH 2/9] Measure external voices per call (swarm 0.8.1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The timeouts were long attributed to prompt size. Measured on one 42 KB diff, one variable at a time, that is wrong: grok high breakage 374s 4 findings grok low breakage 161s 4 findings grok high consistency 28s 6 findings codex high breakage 104s 2 findings A 164 KiB control prompt returned in 20s (grok) / 8.6s (codex). The lens CLUSTER dominates (13x), effort is secondary (2.3x, and bought zero extra findings here), and backends differ 3.6x — grok is simply the slow voice on the cluster whose briefs demand exploration (cross-file-trace reads neighboring files). Size is ruled out. Chunking the diff would therefore target the one variable measurement excludes; splitting by LENS targets the one that dominates. Recorded in the knowledge entry so the next round starts from data instead of the old assumption. - agents.sh: `run --telemetry --unit ` appends one JSON line per call (duration, effective effort/model, prompt bytes, backend rc, timed_out, and the wall the call actually ran under). Written from the EXIT trap, so a timeout is recorded too; the backend's own rc is captured before it is translated into the adapter exit code, or 124 and 1 would be indistinguishable. - telemetry-report.py renders it under the balance block and flags any SURVIVING call at >=60% of its wall — the case backendErrors structurally cannot show, since a voice finishing at 550s and one at 20s are both "ok". - Opt-in end to end: no --telemetry means the previous behaviour, byte for byte. Diagnostics never fail a review — a missing, truncated or malformed file degrades to less output, never a non-zero exit.

Split, the diff-local lenses found four issues the combined call never surfaced. It is NOT a throughput win — the longest call drops only 374->313s and total work rises to 439s, so no single lens split clears the 600s wall. Effort remains the largest untried runtime lever (374->161s for identical findings). Two further effects, neither reachable by lowering effort: a timeout now costs one lens instead of three (the family-critical case — grok is the only third-family voice), and `reach` holds no MANDATORY lens, so the gate may prune the whole call on a diff with no cross-file surface. Fixes found by the new breakage voice reviewing this very branch: - The skill's EXTERNALS_OVERSIZE guard read SWARM_MAX_PROMPT_BYTES without the adapter's validation. A malformed value expands to 0, the threshold goes negative, and EVERY external voice is dropped SILENTLY — while the adapter refuses the same value loudly. Now rejected symmetrically (SWARM_CFG_ERR), pinned by test_lens_sync.py in both directions. - The grok --prompt-file capability probe ran `grok --help` unbounded, outside with_timeout: a wedged CLI would hang the review before any review work. Now capped by SWARM_PROBE_TIMEOUT with -k, degrading to "assume supported" where no timeout binary exists rather than hanging or refusing. - A header comment still promised a --single fallback the preflight replaced with a hard error. Also measured and REJECTED: `grok --max-turns` (10 -> 10s but ZERO findings; 20 -> 279s, 4). The truncated run exits rc=0 with empty findings, so the pipeline reads a silenced voice as "reviewed cleanly, found nothing" — worse than a timeout, which at least reaches backendErrors. Documented in the knowledge entry so it is not retried blind.

The measured reason is **lens crowd-out**, not speed: the old three-lens call returned 3 of its 4 findings from `cross-file-trace` alone, and once split the two-lens `breakage` produced **4 findings the combined call had missed entirely** — three of them confirmed real against this repo, including a config-validation gap that silently dropped every external voice. Two further effects a lower effort cannot buy: a timeout now costs **one lens instead of three** (`correctness`/`removed-behavior` survive it — the family-critical case, since grok is the only third-family voice), and `reach` carries no mandatory lens, so the gate may prune the whole call on a diff with no cross-file surface, where the old layout kept it alive because `correctness` held the cluster open. **Not a speed fix — stated plainly:** the longest single call drops only 374 s → 313 s and total work rises to 439 s; the remaining two-lens cluster is still expensive, so this does not clear the 600 s wall. Cost when the gate keeps `reach`: one extra call per live backend (`≤2×5` by default, unchanged `≤2×11` under `--max`). +- Untagged findings from `reach` now resolve to `cross-file-trace` instead of `unspecified`: a one-lens unit makes the attribution unambiguous, the same rule the other single-lens units already used. +- **Fixes found by the split's own first run** (the new `breakage` voice reviewing this branch): the skill's `EXTERNALS_OVERSIZE` guard read `SWARM_MAX_PROMPT_BYTES` without the adapter's positive-integer validation, so a malformed value made the threshold negative and dropped **every** external voice silently while the adapter would have refused it loudly — it now rejects the same values with `SWARM_CFG_ERR`; the grok `--prompt-file` capability probe ran `grok --help` unbounded outside `with_timeout` and is now capped by `SWARM_PROBE_TIMEOUT` (degrading to "assume supported" where no `timeout` binary exists, rather than hanging or refusing); and a header comment still promised a `--single` fallback that the preflight had replaced with a hard error. +- `test_lens_sync.py` couples `METHODOLOGICAL_LENSES` to the *fact-asserting clusters* (`breakage` + `reach`) rather than to `breakage` alone — the split moved where the lens lives, not what it is, and it must still be verify-gated. + ### 0.8.1 — 2026-08-11 - **Per-call telemetry for the external voices.** `agents.sh run --telemetry --unit ` appends one JSON line per call (duration, effective effort/model, prompt bytes, backend rc, `timed_out`, and the wall the call actually ran under), written from the EXIT trap so a **timeout is recorded too**. `scripts/telemetry-report.py` renders it under the balance block and flags any **surviving** call at ≥60% of its wall — the case `backendErrors` structurally cannot show, since a voice that finished at 550 s and one that finished at 20 s are both just "ok".

Timeout passthrough. The adapter's cap and the Bash window the transport agent runs under both defaulted to 600s, so which fired first was undefined — and when the outer one won, the run lost rc=124, the "timed out after Ns" message and the telemetry timeout flag, leaving a bare killed command. That lost diagnosis is why raising SWARM_TIMEOUT looked counterproductive. It now travels skill → workflow, which pins the adapter cap a margin below the Bash window so it always wins the race, and says so when a requested value exceeds what one Bash call can hold. SWARM_TIMEOUT=0 is passed through, with a log line that the outer window still kills at 600s and will report generically. This does NOT raise the ceiling — only async transport can (tasks/async-poll-external-voices.md). Family coverage. Consensus is defined as ">=2 agreeing families", so losing one silently changes what every CONSENSUS and every solo MEANS: a finding that would have been corroborated is routed through the adversarial verifier instead. The counts look identical to a healthy run — that silent degradation is the reason this task existed. balance now carries familiesExpected/Present/Lost and consensusReachable, and the report prints a warning directly under Bilanz:, including the case where fewer than two families survived and NO finding can reach consensus. Presence is per family, not per call: one dead cluster beside a live one is not a lost family (that stays a backendErrors entry). Both pinned by test_lens_sync.py, including that the Bash window is derived rather than a second hard-coded literal — the tie is the bug.

The measured reason is **lens crowd-out**, not speed: the old three-lens call returned 3 of its 4 findings from `cross-file-trace` alone, and once split the two-lens `breakage` produced **4 findings the combined call had missed entirely** — three of them confirmed real against this repo, including a config-validation gap that silently dropped every external voice. Two further effects a lower effort cannot buy: a timeout now costs **one lens instead of three** (`correctness`/`removed-behavior` survive it — the family-critical case, since grok is the only third-family voice), and `reach` carries no mandatory lens, so the gate may prune the whole call on a diff with no cross-file surface, where the old layout kept it alive because `correctness` held the cluster open. **Not a speed fix — stated plainly:** the longest single call drops only 374 s → 313 s and total work rises to 439 s; the remaining two-lens cluster is still expensive, so this does not clear the 600 s wall.

That release changed the `grok models` bullet marker so only the DEFAULT keeps `*`: * grok-4.6 (default) - grok-4.5 <- the pinned model, invisible to a `*`-only matcher So readiness reported "this CLI does not offer grok-4.5" for a CLI that offers it, and the sole third model family dropped out of the ensemble. No timeout, no error — just two families where the report claimed three. Same damage as the 600s wall this branch is about, reached by a different route. Rather than re-pin to 4.6 and wait for the next break, the model is now DISCOVERED. Ported from ~/dotfiles' cc-harness-agents (same provider), with one gate substituted: that helper withholds an upgrade until a model's context window is known; the adapter withholds it until --json-schema ENFORCEMENT is known, because a model that merely accepts the flag returns structuredOutput:null and fails after a full review is paid for. - GROK_CANONICAL_RE accepts only bare version ids, major >= 4 — rejecting dated snapshots, reasoning/non-reasoning splits, multi-agent, build, composer and image/video variants. Major >= 4 keeps a catalog regressing to grok-3* from pulling the ensemble backwards. - Ordering is component-wise: grok-4.20 beats grok-4.6. As a decimal fraction it would lose, but the provider means the 20th minor release and already ships 4.20-derived ids. - GROK_SCHEMA_VERIFIED is the hard gate AND the upgrade ritual: a newer canonical model is named on stderr, never selected. Verified on CLI 1.0.3 that grok-4.5 and grok-4.6 both return an envelope whose .structuredOutput carries the schema's findings; reviews now run on grok-4.6. - Readiness and the run_grok preflight moved from "is THIS id listed/requested" to "is a schema-verified model on offer/requested" — the exact-id form is what let the marker change drop the backend. An explicit --model still bypasses discovery, never the schema gate. test_grok_models.py pins both listing formats against the SHIPPED awk program (extracted, never re-typed) plus the ordering, the filter against the live 14-id catalog, the verified gate, and that the fallback pin is itself verified. Two self-inflicted test bugs found and fixed while writing it: an extraction regex that silently matched nothing (every assertion then passing over empty output), and a verdict block left mid-file so the discovery half's failures were recorded but never read.

No timeout, no error, just two families where three were reported. The parser now accepts both markers, and `test_grok_models.py` pins both listing formats against the *shipped* awk program. +- **The grok model is discovered, not hard-pinned.** Ported from `~/dotfiles`' `cc-harness-agents` (same provider) with one gate substituted: that helper withholds an upgrade until a model's context window is known, the adapter until its **`--json-schema` enforcement** is known. `GROK_CANONICAL_RE` accepts only bare version ids with major ≥ 4 (rejecting dated snapshots, reasoning splits, multi-agent, build, composer and image/video variants); ordering is component-wise so `grok-4.20` beats `grok-4.6`; `GROK_SCHEMA_VERIFIED` is the hard gate. A newer canonical model is **named on stderr, never selected** — adopting it is a one-line edit after a hand check, not an accident. Reviews now run on **grok-4.6** (verified alongside 4.5 on CLI 1.0.3: both return an envelope whose `.structuredOutput` carries the schema's `findings`). +- Readiness and the `run_grok` preflight both moved from "is THIS id listed / is THIS id requested" to "is a schema-verified model on offer / requested" — the old exact-id form is precisely what let the marker change drop the backend. An explicit `--model` still bypasses discovery, but never the schema gate. + ### 0.9.1 — 2026-08-16 - **Both timeouts now derive from one value.** The adapter's `timeout` cap and the Bash window the transport agent runs under both defaulted to 600 s, so which fired first was undefined — and when the outer one won, the run lost its `rc=124`, its "timed out after Ns" message and its telemetry timeout flag, leaving only a killed command. That lost diagnosis is why raising `SWARM_TIMEOUT` appeared to make things *worse*. `SWARM_TIMEOUT` now travels from the skill into the workflow, which pins the adapter cap a margin below the Bash window (and says so when a requested value exceeds what one Bash call can hold). This does **not** raise the ceiling — only an async transport can, tracked in `async-poll-external-voices` — it makes the ceiling report itself honestly. - **The report says when a model family dropped out.** Consensus is defined as ≥2 agreeing families, so losing one silently changes what every `CONSENSUS` and every solo *means*: a finding that would have been corroborated is instead routed through the adversarial verifier. The numbers look identical to a healthy run. The balance block now carries `familiesExpected` / `familiesPresent` / `familiesLost` / `consensusReachable` and prints a warning directly under `Bilanz:` — including the case where fewer than two families survived, in which no finding can reach consensus at all. A family counts as present if any of its voices returned, so one dead cluster alongside a live one is *not* a lost family (that stays a `backendErrors` entry). diff --git a/plugins/swarm/.claude-plugin/plugin.json b/plugins/swarm/.claude-plugin/plugin.json index 8af68e6..b642727 100644 --- a/plugins/swarm/.claude-plugin/plugin.json +++ b/plugins/swarm/.claude-plugin/plugin.json @@ -1,7 +1,7 @@ { "name": "swarm", "description": "Local mixture-of-agents code review for Claude Code.

The two critical ones were introduced by the preceding commits in this very PR. Degraded-discovery fallback pointed at the NEWEST verified model. That value is reached ONLY when the model list could not be read — precisely when least is known about the host — so a CLI too old to offer grok-4.6 got an unknown model id, rejected every call, and lost the whole grok family for the run. The exact silent-family-loss this branch exists to prevent, reintroduced by its own model bump. It is now the OLDEST verified id; discovery still selects grok-4.6 whenever the list is readable, and the test pins the invariant (oldest verified) rather than the literal value. --unit / --telemetry were interpolated into the transport command unquoted while the neighbouring --lens-instr was shell-quoted. Both go through shQuote now. Also fixed: - The `grok --help` probe read a timed-out probe (rc 124/137, empty stdout) as "flag absent", telling users to upgrade an already-current CLI while the voice died. It degrades like the sibling model probe now. ready_hint blamed the CLI for what is often a missing GROK_SCHEMA_VERIFIED entry; it names the right remedy per case. - Timeout margin 30s -> 60s: it did not cover the adapter's own bounded probes, so the outer Bash window could still win the race. The default no longer requests a value it will always cap, so the "exceeds what one Bash call can hold" warning stops firing on every default run. - Telemetry string fields are JSON-escaped (a malformed record is silently SKIPPED by the reader — it reads as "that voice never ran"), and the report marks calls that died in the adapter before the backend ran, previously indistinguishable from a fast success. - The consensus-unreachable warning no longer hides inside the families-lost branch: a run that only ever had one family loses nothing yet still cannot form consensus, and printed nothing at all. - SWARM_MAX_PROMPT_BYTES normalized with 10# (leading zero was read as octal); the stdin path bounds what it writes to disk instead of measuring after; the report labels grok by family, not by an id it cannot keep current. - Docs swept for discovery + the 5-cluster split. Activation surfaces (plugin.json, marketplace.json, CLAUDE.md) are model-name-free — they load in every session and a version there goes stale by itself. - Test hygiene the review caught in the tests I added last round: a shadowed name, mid-file imports, an unreachable check(), and fixtures that never got cleaned up. Declined: replacing the hand-rolled version ordering with `sort -V`. It works on this host, but the ordering deliberately mirrors the cc-harness-agents implementation that ranks the same ids; two implementations free to diverge cost more than the 40 lines saved.

Both criticals were HALF-DONE fixes from 0.9.3 — the same mistake twice, each time in one half of a pair: SWARM_MAX_PROMPT_BYTES was decimal-forced in the skill but not in the adapter. The two sides of one shared gate then read the same value differently: 0100000 is 100000 in the skill (lets every voice through) and octal 32768 in the adapter (rejects each one), converting the single deterministic skip into exactly the per-call error storm that guard exists to prevent. 080000 additionally died in arithmetic under set -e instead of erroring cleanly. Both sides normalize now, and the test requires it of BOTH rather than of one. The transport command quoted only the arguments 0.9.3 added. ADAPTER and EXTERNAL_PROMPT sat in plain double quotes on the same line — which do not stop $(...), backticks or ${...} from expanding in the shell that runs the string — immediately under the comment explaining why TMPDIR-derived paths must be quoted. Every interpolated path goes through shQuote now. Also: - The empty-prompt guard had weakened from "no visible content" to "zero bytes" when 0.8.0 moved the prompt out of a shell variable, so a whitespace-only prompt would spend a full backend call. Checks for non-whitespace again. - SWARM_TIMEOUT reaches the workflow only when the user actually set it — hardcoding 600 meant the derived default was never used and the "exceeds what one Bash call can hold" warning still fired on every stock run, which 0.9.3 claimed to have stopped. It is decimal-forced too: the value lands in a bare JS numeric literal where 0600 is legacy octal 384. - Telemetry: _json_escape now covers every control character (JSON forbids all of them unescaped, and the reader DROPS a malformed record — which reads as "that voice never ran"); timeout_seconds:0 means cap-disabled, not field-missing, so an uncapped call stops being scored against a wall that never applied; a non-numeric field can no longer crash a report whose whole contract is to never fail a review. - One _bounded_probe primitive replaces a timeout prelude that existed three times and had already drifted: one copy checked rc before trusting output, another swallowed it and read empty output as a definite "flag absent". - Smaller: no empty "(ausgefallen: )" in the case that warning was written for; _grok_version_newer refuses leading-zero components instead of aborting; ready_hint forks once; the prep block reads the prompt size once; the agents skill and pipeline-blueprint caught up with discovery and the 5-cluster split. Declined: folding GROK_CANONICAL_RE into the verified table (the filter must also see UNVERIFIED newer models — that is the entire upgrade signal), and caching grok probes across adapter processes (staleness in a path whose probes are already bounded).

The external voices read project files and research online (finding out-of-diff bugs), jailed under an OS secret-deny sandbox with a hardened egress policy. With `--fix` / `--loop` it also applies the findings you agreed with (only Claude edits; the external agents stay review-only). `--pr []` runs the same ensemble against a GitHub PR's diff and posts the gated result as a PR comment (via your own `gh` auth, after one confirmation) — no CI or API-token setup.
