metrics

A report that measures how long completed work items took and how closely the original estimates matched reality. Lead time covers the whole period from creating the work item to completion, while execution time covers the period between the first and last recorded work timestamps.

In plain words
What is it for?
Use it to review closed stories or requirements that contain timestamped estimation data. The report summarizes item counts, median and p90 times, estimate deviation, and notable patterns by folder or month.
Why use it?
It makes delivery timing and estimation accuracy visible, including pauses between work sessions. This helps reveal patterns that a simple coding-time measure would miss.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.

Security

Grade A, and why

metrics 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 yesterday.

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.

What it actually says

Run the estimation metrics report over this project's closed work items and present the result.

  1. Execute: node "${CLAUDE_PLUGIN_ROOT}/scripts/metrics.js" $ARGUMENTS from the project root (pass the optional YYYY-MM argument through if the user gave a period; add --csv only if the user asked for a CSV/export, which writes docs/work/metrics.csv).
  2. Present the summary conversationally: how many items, median and p90 execution time, average estimate deviation, and anything notable per folder or month. Do not dump the raw table unless the user asks for the detail.
  3. If the script reports no closed items with estimation data, say so and explain what feeds the report: stories/requirements with Status: Closed and a filled ## Estimation table (timezone-stamped Started/Finished). Requires "metrics": true in crew.json for the discipline to be enforced, but the report itself runs anywhere.

The metric is wall-clock, end-to-end: lead time (file creation via git → last Finished) and execution time (first Started → last Finished). It intentionally includes pauses — it measures the cost of the requirement, not keyboard time.

Changes

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.

metrics is a command published in the GitHub repository jircdev/crew-plugin (2 stars, last pushed 12d ago), licensed MIT. It adds 12 tokens to every session and 279 once invoked, about $0.0001 per session on Opus 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.
