Conciseness

The body is dense with operational, non-obvious detail and explains nothing Claude already knows, but guidance is restated in several places — the 404/'Moment not warm' retry advice appears three times, cancel guidance twice, and the Example Workflow recaps commands already covered — so it could still be trimmed. This fits 'efficient; minor instances of over-explanation that could be trimmed' better than anchor 3, since the padding is deliberate repetition rather than unnecessary explanation.

Actionability

Every workflow ships copy-paste-ready commands: the jq status pipeline, 'snouty debug ... --title', 'snouty runs exec "$RUN_ID" -1520695250096255483 67.7622960046865 uptime', tar+base64 file extraction, and the runs-search moment queries. Specific examples cover the common cases (cold moment rewarm, crashed container, Kubernetes tests), matching the fully-executable anchor exactly.

Workflow Clarity

A clear six-step example workflow (prerequisites → session → moment → exec → results → cancel) is backed by explicit validation checkpoints ('snouty --version' ≥ 0.8.0, checking for 'in_progress:ready', 'runs wait --until ready'), error-recovery feedback loops (retry on 404, search output before re-running after a timeout), and a Self-Review checklist before reporting back. Destructive operations (cancel) are gated on asking the user first, satisfying the validation cap.

Progressive Disclosure

Core command usage stays inline while specialized material is split into five clearly signaled, one-level-deep references that all exist on disk (moments.md, kubernetes.md, gdb.md, virtual-time.md, errors.md), each linked at the exact decision point ('If the user didn't give you a moment, read references/moments.md'). This matches the anchor for a clear overview with well-signaled references and easy navigation.

Specificity

It lists multiple concrete actions — 'Run a bash script inside an Antithesis run at a chosen moment', 'process and container inspection, on-disk evidence, gdb attach, and general debugging' — giving comprehensive, non-generic coverage in third-person voice. Not anchor 4 because coverage of the capability surface is essentially complete, not just 'several specific actions' with gaps.

Completeness

It explicitly answers both: what — 'Run a bash script inside an Antithesis run at a chosen moment with `snouty runs exec`, from the terminal and without a browser' — and when — 'Use it for scripted forensics on a run: process and container inspection, on-disk evidence, gdb attach, and general debugging', with concrete trigger activities. The explicit 'Use it for' clause satisfies the completeness cap guideline.

Trigger Term Quality

Good natural-language coverage users would actually say — 'debug', 'debugging', 'forensics', 'inspection', 'gdb', 'Antithesis run' — but a few common phrasings are absent, e.g. investigating a 'failing property' or 'troubleshooting' a run, which the body's When-to-use section treats as the primary trigger. Fits 'good keyword coverage; a few natural terms missing' rather than the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

The description is anchored to a clear niche — Antithesis runs, `snouty runs exec`, moment-pinned debugging, virtual time — that no generic skill would claim, giving minimal conflict risk. Anchor 4's 'minor overlap risk with closely related skills' doesn't apply since no competing trigger surface is shared.
