From 3d8f24d1df914710175e4e7a53043e9b1cf64147 Mon Sep 17 00:00:00 2001 From: Robert Gering Date: Thu, 6 Aug 2026 15:35:31 +0200 Subject: [PATCH 1/5] 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 6fae71c3beb6ed9eca9846c515ba3bea019b3aa0 Mon Sep 17 00:00:00 2001 From: Robert Gering Date: Tue, 11 Aug 2026 15:50:28 +0200 Subject: [PATCH 2/5] 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". Opt-in: without `--telemetry` the adapter behaves exactly as before. - **Measured what actually drives runtime** (same 42 KB diff, one variable at a time): the lens **cluster** dominates at **13x** (grok/breakage 374 s vs. grok/consistency 28 s), **effort** is secondary at **2.3x** (374 s → 161 s at `low`, for the same 4 findings), and **backends differ 3.6x** (codex 104 s vs. grok 374 s on the identical breakage prompt).

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.
