Conciseness

Mostly lean: the failure-mode and blocked/warning tables are dense and every row carries a rule; no space is spent explaining concepts Claude already knows. Not a 5: minor trimmable parts remain — the vague 'Consumers' paragraph with its 'harness-routing convention' parenthetical, and rhetorical flourishes like "A missing link is honest. An indirect link is a broken promise."

Actionability

Concrete and executable in most places: exact path template `reports/{category}/{YYYY-MM-DD-HHMM}.md`, a full frontmatter block, keyword mappings, a paste-able LLM gate snippet, and specific error handling (`write_pending`, exit 10, `gbrain write-request <request_id>`). Not a 5: "Load latest. Given a category, find the most recent report file" gives no command or mechanism, and the save phase doesn't state the write command.

Workflow Clarity

The Actionability Gate retry loop is exemplary — compose, scan every link (with `git status` and `gbrain get <slug>` as explicit checkpoints), fix, re-check, capped at 2 retries — which is a true validate-fix-retry feedback loop. Not a 5: the save/load phases have validation gaps (no post-write verification in the phase list, and the load step is underspecified), so it sits between anchors 4 and 5.

Progressive Disclosure

Well-organized sections (Contract, Phases, Actionability Gate, When it fails, Anti-Patterns) with clearly signaled one-level references to external docs (`../conventions/agent-operator-protocol.md`, `skills/briefing/SKILL.md`); no bundle files exist to verify beyond the body. Not a 5: the ~70-line Actionability Gate section is a candidate for a separate reference file, which would keep SKILL.md a leaner overview.

Specificity

Names several concrete actions — "Save and load timestamped reports", "Keyword routing for fast lookup", "delivery-time link checks (Broken/Dead/Indirect/Missing)" — with a specific failure taxonomy. Not a 5: coverage has gaps, e.g. the search/query capability only appears in the body, not the description.

Completeness

The "what" is clear (save/load timestamped reports with keyword routing and link checks), and the "when" is stated explicitly via "Cron jobs save output as reports; the agent or user queries them by keyword" plus the consumers named (briefings, digests, research reports). Not a 5 because there is no explicit "Use when..." clause and the trigger guidance could be more specific.

Trigger Term Quality

Includes natural phrases users would say — "briefings", "meeting digests", "research reports", "save and load ... reports" — alongside the more technical "Actionability Gate". Not a 5: common variations and synonyms (e.g. "latest report", "show me the briefing") appear only in the triggers list, not the description itself.

Distinctiveness Conflict Risk

The timestamped-report format, keyword routing, and named Actionability Gate taxonomy give it a distinct identity unlikely to collide with unrelated skills. Not a 5: "save and load reports" is a fairly common capability shape, leaving minor overlap risk with generic note/save skills.
