Conciseness

The 47-line body assumes Claude's competence throughout: no concept is explained (no definition of FCC, GitHub issues, or reactions), and every sentence carries operational weight (e.g., "one location's failure does not establish decommissioning", "do not probe private/operator networks to classify a report"). It matches the 'lean and efficient; every token earns its place' anchor; not 4 because there is no section that could be trimmed without losing guidance.

Actionability

Concrete, copy-paste-ready commands are provided for retrieval (two `gh api ... --paginate` variants including the incremental `since` form) and for reactions (`gh api repos/.../reactions -f content=rocket`), plus exact document paths, exact reference file, and a concrete cross-language verification step ("Check that address/port pairs and locality annotations agree across languages"). It matches the 'fully executable; specific examples cover the common cases' anchor; not 4 because the editing instructions (grouping, ordering, entry extension) are specific enough that no key execution detail is missing.

Workflow Clarity

The workflow is clearly sequenced (retrieve evidence → classify → validate → apply doc edits → translate → verify cross-language → react → report → update checkpoint) with explicit validation steps ("Validate address/port syntax and check the current collection for duplicates") and error-recovery feedback loops ("If a mutation returns an uncertain result, inspect existing reactions before retrying", "do not advance past work lost to a fetch or translation failure", "without moving the checkpoint backward"). This matches the 5 anchor's 'explicit validation steps; feedback loops for error recovery'; the batch/destructive cap does not apply because validation and rollback guards are present.

Progressive Disclosure

The short body is a clear overview that delegates the long-lived state and detailed conventions to a single, well-signaled one-level-deep reference — "Use [update-memory.md](references/update-memory.md) for the checkpoint, document paths, locality caveats, and grouping conventions" — and the bundle file exists at references/update-memory.md (60 lines) containing exactly those things (checkpoint, doc paths, locality caveats, grouping/format, update log). It matches the 'clear overview with well-signaled one-level-deep references' anchor; the cross-skill pointer to ../translate-docs-zh-en/SKILL.md is clearly signaled and one hop, not a nested chain.

Specificity

"Check or update the rtp2httpd FCC address collection using community reports in GitHub issue 5" names two concrete actions against a precisely identified target (rtp2httpd FCC collection, GitHub issue 5), matching the 'several specific actions; minor gaps in coverage' anchor. It falls short of 5 because sub-operations of an update (adding addresses, syncing the English doc, contributor reactions) are not enumerated, and stays above 3 because the object of the actions is far more specific than the 'Processes PDF files and extracts content' level.

Completeness

The 'what' is clear (check or update the FCC address collection from issue 5 reports), but there is no 'Use when...' clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. The 'when' is only weakly implied by the verbs "Check or update", fitting the anchor 'Has a clear what but when is missing or only weakly implied' rather than the 4 anchor's explicit 'when'.

Trigger Term Quality

"rtp2httpd FCC address collection", "community reports", "GitHub issue", and "Check or update" are natural phrases a user of this repo would say, giving good keyword coverage with only a few natural terms missing. Not 5 because common synonyms and variations a user might say ("IP addresses", "IPTV", "sync", "multicast") are absent; not 3 because coverage clearly exceeds the 'Works with PDF files' single-keyword level.

Distinctiveness Conflict Risk

Naming the specific repository (rtp2httpd), the specific artifact (FCC address collection), and the specific source (GitHub issue 5) creates a clear niche with distinct triggers and minimal conflict risk with any other skill. It matches the 5 anchor exactly; nothing generic remains that could overlap with another skill.
