Conciseness

Every section adds non-obvious information: exact tool calls ("memory_sessions { ... }", "memory_recall { ... }"), the directory-boundary rule, pagination handling, and provenance checking — no explanation of what sessions or memory are. The boundary-check point recurs in Why/Workflow/Anti-patterns/Checklist, but each occurrence serves a distinct function (rationale, procedure, contrast example, verification) rather than padding, so it fits the score-5 anchor ("every token earns its place") better than score 4's "minor instances of over-explanation".

Actionability

Guidance is fully executable: concrete JSON tool-call examples, exact match expression ("session.cwd === projectPath || session.cwd.startsWith(projectPath + sep)"), explicit path resolution ("path.resolve(process.cwd(), $ARGUMENTS)"), pagination instructions ("follow nextCursor ... Preserve filters between pages"), and a concrete expected-output sample. This matches the score-5 anchor (copy-paste ready, covers common cases); score 4's "minor gaps" does not apply.

Workflow Clarity

Five clearly sequenced steps with explicit checkpoints: provenance validation in step 4 ("Check each result's session or project provenance before including it"), failure handling in step 2 ("No match: report that this project has no matching session and stop"), plus a Checklist section for verification. The operation is read-only (no destructive/batch cap applies), matching the score-5 anchor's explicit validation and verification steps; score 4 would require a missing checkpoint, and none is missing.

Progressive Disclosure

Sections are well organized and the one external reference is clearly signaled and one level deep ("See [TROUBLESHOOTING.md](TROUBLESHOOTING.md) if memory_sessions or memory_recall is not available"), fitting score 4's "good structure; references mostly clear". It falls short of score 5 because the referenced TROUBLESHOOTING.md is not present in the bundle (no references/, scripts/, assets/, or TROUBLESHOOTING.md exists alongside SKILL.md), leaving a dangling link, and the "See also" skills ("recap, session-history, recall") are named without paths or links.

Specificity

"Resume the most recent agent session for the current working directory, leading with any unanswered question" names the domain plus multiple concrete actions (resume most recent session, match by cwd, lead with the unanswered question) with comprehensive coverage for this narrow skill. It uses third person ("Resume", not "I"/"You") and matches the score-5 anchor's multiple-specific-actions pattern; the score-4 anchor's "minor gaps in coverage" does not apply since nothing in the skill's scope is left out of the description.

Completeness

Both questions are answered explicitly: the what ("Resume the most recent agent session for the current working directory, leading with any unanswered question") and the when ("Use when the user says 'where were we', 'resume', 'handoff', 'pick up where I left off', or starts a session with no fresh context"). This mirrors the score-5 anchor example structure exactly; score 4 would require the 'when' to be less explicit, which it is not.

Trigger Term Quality

The trigger list "where were we", "resume", "handoff", "pick up where I left off" plus "starts a session with no fresh context" covers natural synonyms a user would actually say, matching the score-5 anchor (comprehensive natural terms including synonyms). It clearly exceeds score 4 ("a few natural terms missing") because every common phrasing for session resumption is present.

Distinctiveness Conflict Risk

"handoff" / "pick up where I left off" / "where were we" are distinct triggers tied to a clear niche (resuming the most recent session for the current directory), giving minimal conflict risk per the score-5 anchor. It is not the broad, overlapping phrasing of score 4 ("minor overlap risk with closely related skills"), though sibling skills like recap exist — the specific trigger phrases keep this distinguishable.
