Conciseness

The body is lean, assumes Claude's competence, and explains only `trellis mem`-specific facts rather than general concepts, with tight aphoristic framing ('It is a tool, not a ceremony').

Actionability

Provides fully executable, copy-paste-ready bash commands (`trellis mem search`, `extract ... --phase brainstorm`, `context ... --turns 3 --around 2`) with real flags and arguments.

Workflow Clarity

Though explicitly a capability skill rather than a fixed workflow, its decision logic is clearly sequenced via the 'When to reach / When NOT / What to do with results' structure; as a read-only operation it needs no validation loop, fitting the simple-skills allowance for an unambiguous single action.

Progressive Disclosure

The body is an overview pointing to two real, one-level-deep, clearly signaled references (`references/cli-quick-reference.md`, `references/triggering-patterns.md`) that were verified to exist and hold the promised detail.

Specificity

Names the concrete tool (`trellis mem` CLI) and lists multiple specific concrete actions including returning raw dialogue and several disposition options (update spec, append notes, quote inline, internalize), matching the score-3 anchor for listing multiple specific actions.

Completeness

Clearly answers both 'what' (reaches into past conversation history via `trellis mem`) and 'when' with an explicit 'Use whenever...' trigger clause enumerating multiple scenarios.

Trigger Term Quality

Includes verbatim natural phrasings users would say in both English ('how did we solve X last time') and Chinese ('上次怎么解的'), plus scenario triggers like familiar-bug debugging — strong natural-term coverage.

Distinctiveness Conflict Risk

Occupies a clear niche (cross-session memory recall via `trellis mem`) with distinct bilingual triggers specific enough to be unlikely to fire for unrelated skills.
