Conciseness

Mostly efficient (tables, exact paths, tight step descriptions) but with real duplication: the 'Invocation Triggers' section repeats the frontmatter description verbatim, 'Anti-Patterns To Reject' (9 items) largely restates 'Critical Rules', and the NEVER-SEND rule appears ~6 times — some repetition is a deliberate safety design, but the doc flags its own redundancy ('Stated multiple times'), fitting the 3 anchor ('could be tightened') rather than the 4 anchor's 'minor instances'.

Actionability

The guidance is largely concrete (exact KB paths, script invocations with flags, report section/format spec, decision tables), but every named executor — scripts/kb_reader.py, scripts/search_window_calculator.py, scripts/draft_safety_validator.py — and all three references/*.md files are missing from the bundle, and the Step 1 window computation is pseudocode ('window_start = now - 9_hours'), so key details needed to execute live only in nonexistent files. This fits the 3 anchor ('some concrete guidance but incomplete… missing key details') rather than 4, where gaps would be minor.

Workflow Clarity

Steps 0–10 are clearly sequenced with fail-fast prerequisites, explicit skip/stop conditions, an empty-inbox path, and an error-handling table with per-situation behaviors — but the central safety validation has no recovery loop: draft_safety_validator.py 'FAILs if detected' with no stated remediation step. This fits the 4 anchor ('most checkpoints present; minor validation gaps'); the 5 anchor would require an explicit feedback loop for that failure.

Progressive Disclosure

The body is well-sectioned with clearly signaled, one-level-deep reference links (kb_file_contract.md, triage_decision_framework.md, drafts_only_safety.md), but scored against the actual bundle structure, all three referenced files (and all three scripts) are absent — the promised detail material is missing, so the disclosure structure is incomplete. This lands at the 3 anchor ('some structure but could be better organized'); the 2 anchor would require inlined bulk content or buried references, which is not the case.

Specificity

The description lists seven-plus concrete actions ("Searches recent emails, classifies them via the user's taxonomy, researches new senders, generates recommendations, drafts replies (NEVER sends), delivers a report in the user's preferred format, and updates the knowledge base") with comprehensive pipeline coverage including the safety property, matching the 5 anchor for multiple specific concrete actions rather than the 4 anchor's 'minor gaps in coverage'.

Completeness

Both 'what' and 'when' are explicitly answered: the full triage pipeline states what it does, and "Designed to run on a recurring schedule (1-3x daily) or on demand. Use when the user wants their inbox processed, in any variation (e.g., ...)" gives explicit trigger guidance with concrete phrases, exactly matching the 5 anchor.

Trigger Term Quality

Eight natural user phrasings are enumerated ("triage my inbox", "inbox triage", "check my email", "run email triage", "process my inbox", "what's new in my email", "handle my email", "email triage") covering verb and noun synonym variations comprehensively, matching the 5 anchor rather than the 4 anchor's 'a few natural terms missing'.

Distinctiveness Conflict Risk

The recurring-triage niche is clear and "Requires the inbox-setup skill to have been run first" disambiguates the paired sibling, but generic triggers like "check my email" and "handle my email" share the email domain with the closely related inbox-setup skill, creating minor overlap risk — between the 4 anchor ('minor overlap risk with closely related skills') and the 5 anchor ('minimal conflict risk').
