Conciseness

The body is mostly lean, command-first prose, but the error-handling section offers two alternative packages ("uv tool install claude-code-tools" / "cargo install aichat-search") with no guidance on choosing between them, plus tangential curl installers and a prerequisite ("Node.js 18+ (for action menus)") referencing a feature never explained. Not 2 because the core workflow is efficient and unpadded; not 4 because the install block's choice-parity and stray prerequisite are unnecessary content.

Actionability

Concrete executable commands appear throughout — `aichat search --json -n 10 "[query]"` with the `-g "project"` filter, the session-file path pattern `~/.claude/projects/*/[session-id].jsonl`, and a worked example. Not 5 because step 3 says "Use `jq` to extract fields" without showing the actual jq expression, leaving a small execution gap.

Workflow Clarity

The five-step workflow is clearly sequenced (understand → search → parse → deep-dive with a 3-file cap → summarize) and includes error-recovery paths ("If no results found, suggest alternative search terms" and the command-failure handling section). Not 5 because checkpoints are implicit in the step list rather than embedded as explicit validation steps; the read-only nature of the skill means no destructive/batch cap applies.

Progressive Disclosure

Sections are clean and well-labeled (Workflow, Output Format, Example, Constraints, Error Handling) and the skill is appropriately self-contained with no bundle files or nested references. Not 5 because the ~74-line body exceeds the under-50-line simple-skill exception and the install/prerequisites block is a minor organization gap mixing recovery guidance with environment setup.

Specificity

"Search previous code agent sessions for specific work, decisions, or code patterns" names the domain and one concrete action with its search targets, but stops short of the several specific actions (parse, deep-dive, summarize) the skill actually performs. Not score 2 because the action and targets are concrete rather than generic; not 4 because only one action is enumerated.

Completeness

The "what" is clear (search previous sessions for work, decisions, patterns), but there is no user-task "Use when..." clause — the only conditional is the agent-scoping "For CLI agents WITHOUT subagent support (e.g., Codex CLI)", which addresses which agent should invoke it, not when the task arises. Per the judging guidelines, a missing explicit trigger clause caps completeness at 3.

Trigger Term Quality

Natural terms like "search", "sessions", "decisions", and "code patterns" are present, but common variations users would say — "history", "past conversations", "transcripts", "find" — are absent. Not 4 because the missing synonyms are among the most likely user phrasings for this need.

Distinctiveness Conflict Risk

"Previous code agent sessions" carves a clear niche, and the agent-conditional scoping further separates it from sibling skills (e.g., a subagent-based equivalent). Not 5 because somewhat generic phrases like "code patterns" and "specific work" leave minor overlap risk with general search or memory skills.
