A read-only metrics report for Acu pipelines. It calculates measures such as how often work completes without human intervention, gate pass rates, cycle times, and recurring problem alerts from logs and status files.

Use it to review pipeline performance, find failing or slow gates, classify work units by audit history, and display alerts or machine-readable metrics.

It makes patterns across completed work visible without manually calculating results from individual pipeline records.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00040	$0.00802
Opus 5.5	$0.00016	$0.00321
Sonnet 5.5	$0.00008	$0.00160
Haiku 4.5	$0.00004	$0.00080

Security

Grade A, and why

acu-pulse scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/acu-pulse — Pipeline Health Metrics

Read-only diagnostic skill. Computes autonomy rate, gate pass rates, cycle times, and pattern alerts from audit logs across all pipelines.

Protocol

Step 1: RUN — Execute pulse.mjs

Run the metrics script from the repository root:

node pulse.mjs

If the user asks for machine-readable output, use node pulse.mjs --json instead. If the user only wants alerts, use node pulse.mjs --alerts.

Step 2: INTERPRET — Analyze the output

The script produces five sections. Interpret each:

Unit Classifications

Each work unit is classified by its audit history:

Class	Meaning
CLEAN	Zero structural failures
NEAR-CLEAN	One structural failure (resolved)
TROUBLED	Two or more structural failures
BLOCKED	Currently stuck — last gate result is FAIL

Autonomy Rate

Percentage of completed units that ran clean with zero human intervention. Only completed units count. Bug-induced units are excluded (they pollute the signal).

Gate Pass Rates

Cross-pipeline pass/fail ratio per gate type. Low-rate gates are bottlenecks — they may indicate unclear specs, overly strict checks, or systemic quality issues at that stage transition.

Alerts

[STALL] — No gate transition in 14+ days. Unit may be abandoned or blocked.

Cycle Times

Wall-clock duration per stage from status.yaml timestamps. Useful for identifying stages that take disproportionately long, but note these include idle time (not active work time).

Gate Analytics

Deep metrics on gate performance:

First-pass rate — percentage of units that pass each gate on their first attempt. Lower rates indicate unclear specs or overly strict exit criteria.
Retry times — average wall-clock time between a gate failure and the next attempt.
Top failure causes — most common structural check failures across pipelines.

Pipeline Metrics

Per-pipeline health indicators:

Completion rate — units reaching final stage vs total created. Low rates indicate systemic stalls.
Stage velocity — average/min/max time per stage type across all pipelines. Identifies slow stages.
Stall detection — units with no gate transition in 14+ days. Surfaced as [STALL] alerts.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

acu-pulse is a skill published in the GitHub repository Acquiredl/Acu (2 stars, last pushed 2mo ago), licensed MIT. It adds 40 tokens to every session and 802 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
