Conciseness

Every section earns its place (When to Use, Do NOT invoke, command, args table, examples, output format, notes) with no concept explanations Claude wouldn't know. Minor trimming possible: the opening line ("not already documented in context, memories, or Markdown files in the codebase") largely repeats the "Do NOT invoke" section. Fits anchor 4 (efficient, minor instances that could be trimmed) rather than 5's every-token-earns-its-place.

Actionability

Gives the exact executable command with a realistic example ("API rate limits are 100 req/min per tenant"), an argument table, three additional copy-paste examples covering distinct scenarios, and the exact output format. The referenced script scripts/log-learning.sh exists in the bundle and behaves as documented (appends timestamped entries to .claude/learning.yaml). Fully executable and copy-paste ready — anchor 5.

Workflow Clarity

This is a simple single-action skill: run the logging script with a summary. Per the simple-skill exception, a single unambiguous action can score 5; here the action, its argument, and its effect are all unambiguous, and the operation is non-destructive (a single append, with argument validation inside the script itself).

Progressive Disclosure

The body is ~60 lines of well-organized single-level content: no inlined material that belongs in a separate file, and its one bundle dependency (scripts/log-learning.sh) is correctly referenced and matches the actual bundle structure. Clear section headers make navigation trivial, fitting the simple-skill exception for well-organized skills with no need for external references.

Specificity

"Capture new learnings discovered during code exploration or user interaction" names the domain and a concrete action, and enumerates contexts ("codebase, tools, workflows, or domain knowledge"), but offers only one action (capture/log) with no detail on how learnings are recorded. This matches anchor 3 (domain plus 1-2 concrete actions, not comprehensive) rather than anchor 4, which requires several specific actions.

Completeness

Both parts are present: the "what" ("Capture new learnings ... that were not present in context, memories, or codebase documentation") and an explicit "when" ("This skill should be invoked when Claude discovers something new ... that could benefit future sessions"). The "when" clause is explicit but reads as generic instruction rather than concrete trigger phrasing, so it fits anchor 4 (both present, when could be more explicit) rather than anchor 5.

Trigger Term Quality

Includes solid natural keywords like "code exploration", "user interaction", "tools", "workflows", "domain knowledge", and "codebase documentation". A few natural trigger phrases users would actually say are missing (e.g., "learned something new", "undocumented behavior", "remember this for later"), keeping it at anchor 4 rather than 5's comprehensive synonym/variation coverage.

Distinctiveness Conflict Risk

The scope is fairly distinct — capturing newly discovered knowledge that is explicitly *not* in context, memories, or documentation — with a clear niche versus general documentation skills. Minor overlap risk remains with memory-management or documentation-writing skills that also "capture information", matching anchor 4 rather than 5's minimal-conflict clear niche.
