Conciseness

The body is dense with hard operational facts (exit codes, byte caps, copy-divergence gates) rather than padding about known concepts, but sections like the Kimi home-discovery procedure, the tool-evidence flag/exit-code semantics, and the dated '战例（2026-09-18）' anecdote run long and could be tightened or externalized. It sits above 'noticeably verbose' (2) but carries more than 'minor' over-length, matching 'mostly efficient but could be tightened' (3).

Actionability

Every route resolves to an exact, copy-paste-ready command ('scripts/read_claude_session.py --session <ID> --tool-evidence --contains <literal>', 'python3 scripts/skill_usage_ledger.py index'), all of which exist in scripts/, with expected outputs and exit-code semantics stated per mode. This matches the 'fully executable, copy-paste ready, specific examples cover the common cases' anchor; it is not level 4 because no route leaves the executor guessing at flags or arguments.

Workflow Clarity

The routing table maps each user intent to a specific command, and multi-step flows carry explicit validation: recovery runs a report first and writes 'only after the user asked to recover content', the negative-claims section imposes a pre-assertion checklist, and readers 'fail visibly' on divergent copies with prescribed retry ('repeat only this read'). This matches 'clear sequence with explicit validation steps; feedback loops for error recovery; checklists for complex processes'; the destructive-operation cap does not apply because the write path is validated.

Progressive Disclosure

All six referenced files exist in references/ and are one level deep with purpose-conditioned pointers ('Read references/session_file_format.md when interpreting schemas...'), and the nine bundled scripts are real. It falls short of 5 because the SKILL.md body itself inlines substantial reference-grade detail (tool-evidence selector semantics, the four-step Kimi home-location procedure) that belongs in a bundled reference, keeping it at 'good structure; most content appropriately placed; minor organization gaps'.

Specificity

The description enumerates concrete capabilities: 'Reads, searches and exports local Claude Code and Kimi CLI history', 'timelines, verbatim user input, keyword or fuzzy recall, file recovery from transcripts, and which session ran a given command in a known time window'. Multiple specific concrete actions with comprehensive coverage, written in third person ('Reads, searches and exports') — this matches the 5 anchor rather than 4, which would require minor coverage gaps.

Completeness

The 'what' is explicit (reads/searches/exports with five enumerated capabilities) and the 'when' is explicit with concrete trigger phrases: 'Use when the user asks what was said, wants a session ID or original context, needs proof of what a session contained, or needs past-session runtime evidence'. It even adds negative routing ('Not for Codex (use read-codex-history); with no platform or several named, start at local-conversation-history'), clearly matching the 5 anchor.

Trigger Term Quality

Natural user phrasings are present: 'what was said', 'wants a session ID or original context', 'needs proof of what a session contained', 'commands, tool calls and hook runs', plus 'transcript files'. Good keyword coverage, but common variations a user might actually say — 'conversation', 'previous chat', 'past sessions', 'what did we do' — are missing, so it fits 'good keyword coverage; a few natural terms missing' (4) rather than comprehensive synonym coverage (5).

Distinctiveness Conflict Risk

It carves a clear niche — reading local Claude Code/Kimi history 'without resuming work' — and actively disambiguates adjacent skills: 'Not for Codex (use read-codex-history)' and 'with no platform or several named, start at local-conversation-history'. Distinct triggers and explicit boundary routing give minimal conflict risk, matching the 5 anchor.
