Conciseness

Several sections restate what Claude already knows or what the frontmatter already specifies: the Priority Guidelines table ("critical | Blocks core functionality, data loss risk, security issue"), the Area Tags table ("frontend | UI, components, client-side code"), the Detection Triggers section duplicating the description's trigger list, and the Copilot Chat Integration prompts. Not 2 because the core operational material (entry templates, ID format, grep commands, promotion rule) is dense and earns its tokens; not 4 because the padding is more than minor trimmable instances.

Actionability

Fully executable throughout: complete copy-paste entry templates for all three file types, ID format with concrete examples ("LRN-20250115-001", "ERR-20250115-A3F"), runnable commands ("grep -n \"Pattern-Key: <pattern_key>\" .learnings/LEARNINGS.md", "./skills/self-improvement/scripts/extract-skill.sh skill-name --dry-run"), and concrete promotion examples showing verbose learning → concise CLAUDE.md rule. Covers the common cases (log, dedupe, resolve, promote, extract) with no gaps.

Workflow Clarity

Multi-step workflows are clearly sequenced with an explicit promotion threshold ("Recurrence-Count >= 3", 2 distinct tasks, 30-day window), search-first dedupe, a dry-run step, a "Verify: Read skill in fresh session to ensure it's self-contained" checkpoint, and a Skill Quality Gates checklist. Not 5 because the promotion and resolution workflows lack the explicit verification checkpoints that extraction has (e.g., no step confirming the promoted rule actually landed in the target file). Not 3 because sequences are complete and checkpoints exist in the risky workflows.

Progressive Disclosure

References are one level deep, clearly signaled as markdown links, and gated ("Read these only when installing or configuring the skill"); installation.md, hooks-setup.md, amp-setup.md, and context-maintenance.md all exist in references/, and scripts/extract-skill.sh exists. Not 5 because references/examples.md is never linked from the body, leaving part of the bundle undiscoverable from SKILL.md, and the 485-line body keeps some material (full entry templates) inline that could live in a reference file. Not 3 because structure and navigation are otherwise good with clearly signaled references.

Specificity

Lists multiple concrete actions covering the domain's full cycle: "Captures learnings, errors, corrections, and feature requests", "distill into a memory file or new skill", "promotes accumulated patterns", and "review learnings before major tasks". Not 4 because coverage spans capture, promotion, and review phases with no obvious minor gaps left unstated.

Completeness

Explicitly answers "what" ("Captures learnings, errors, corrections, and feature requests to enable continuous improvement") and "when" with five numbered trigger conditions plus review timing ("Also review learnings before major tasks"). Not 4 because the "when" clause is fully explicit with concrete trigger phrases rather than merely present-but-improvable.

Trigger Term Quality

Includes literal natural phrases users say when this skill applies ("'No, that's wrong...'", "'Actually...'") plus condition-style triggers ("requests a capability that doesn't exist", "knowledge is outdated or incorrect", "A better approach is discovered for a recurring task"). Not 4 because both conversational quotes and their condition synonyms are present; no natural variant is obviously missing (file extensions are N/A for a conversation-triggered skill).

Distinctiveness Conflict Risk

Actively routes overlap-prone neighbors elsewhere: "For ACTIVE runtime failures where the agent needs to apply and verify a fix mid-task, use `self-healing` instead" and "For CI-only/headless learning capture, use self-improvement-ci", carving a clear niche. Not 4 because adjacent skills are explicitly disambiguated rather than differing only in wording.
