The description names the domain ('fan-out search across all memory sources') and one core action (searching when context is unclear), but doesn't list multiple concrete actions like retrieving, summarizing, or correlating past conversations. 'Fan-out search' is somewhat technical and the actual capabilities beyond searching are not detailed.

Clearly answers both 'what' (fan-out search across all memory sources when context is unclear or vaguely referenced) and 'when' (explicit trigger phrases listed plus the general condition 'any vague reference to past context that needs resolution before the agent can act'). The trigger guidance is thorough and explicit.

Excellent coverage of natural trigger phrases users would actually say: 'from earlier', 'remember when', 'what we discussed', 'that thing with', 'we talked about', 'last session', 'the other day', etc. These are highly natural and comprehensive variations of how users reference past context.

While the trigger phrases are specific, 'search across all memory sources' could overlap with other memory-related skills (e.g., a specific memory retrieval skill or a conversation history skill). The description doesn't clearly distinguish itself from other memory/recall skills that might exist in a larger skill set.

The skill is lean and efficient. Every section serves a purpose — trigger detection, search sources, workflow, timeouts, anti-patterns. There's no explanation of what grep does or how memory works conceptually. The trigger list is necessarily verbose but earns its place as a reference lookup.

Provides fully executable bash commands for each memory source, specific file paths, concrete tool invocations (session_context, redis-cli, slog), and copy-paste ready examples with good/bad timeout patterns. The keyword extraction example ('Those photos from earlier' → keywords) is a concrete worked example.

The 5-step workflow is clearly sequenced (extract → fan out → synthesize → present → handle failure). Explicit validation via the 'If nothing found' step prevents fabrication. Mandatory timeouts serve as safety checkpoints. The anti-patterns section provides clear guardrails against common failure modes.

The content is well-structured with clear headers and numbered sources, but everything is inline in a single file. The 8 search sources section is fairly long and could benefit from being split into a reference file, with SKILL.md providing just the overview and workflow. However, for a skill of this size (~100 lines), it's borderline acceptable.
