Conciseness

The body is lean and command-driven, but the 'What this does' intro ('A calendar full of reactions is not a plan') and the Rules section editorialize Newport philosophy Claude already knows ('More than 4 deep hours is fake depth', 'open loops steal tomorrow's first block') rather than instructing. This is 'efficient with minor instances of over-explanation that could be trimmed' (4), not 5, since a few sentences are motivational restatement rather than operational content.

Actionability

Fully executable, copy-paste-ready commands with real flags and example values for all three scripts (e.g., 'python scripts/time_block_planner.py --start 08:30 --end 17:00 --lunch 12:30 --task "Write product spec:120:deep"'), documented exit codes, and a script role table. Matches the score-5 anchor: specific examples cover the common cases.

Workflow Clarity

Steps 1–4 are clearly sequenced (classify → budget gate → block → log → shutdown) with explicit validation checkpoints and feedback loops: 'OVER-BUDGET (exit 2) means cut, batch, or delegate before any schedule is built' and 'Two refusals, both exit 2 ... the planner names what to defer / what to drop — the day never silently extends'. This matches the score-5 anchor with explicit validation and error-recovery guidance.

Progressive Disclosure

The SKILL.md is a clear overview with a script table, and well-signaled one-level-deep references and assets ('references/deep_work_canon.md', 'references/time_blocking_method.md', 'references/shallow_work_budget.md', 'assets/example_time_block_plan.md', 'assets/shutdown_checklist.md' — all verified to exist with no nested references inside them), each with a one-line role description. Matches the score-5 anchor: appropriate split, easy navigation.

Specificity

The description lists multiple concrete actions — 'Classifies tasks deep vs shallow, builds an energy-first time-blocked schedule that refuses deep demand past the 4-hour ceiling, batches shallow work into at most two windows, and logs focus sessions against a weekly target' — with specific parameters (90-minute blocks implied via body, 4-hour ceiling, two windows, weekly target). It is comprehensive and matches the score-5 anchor; not 4 because there are no coverage gaps.

Completeness

It explicitly answers 'when' ('Use when someone wants to plan a deep work day... or says "/deep-work" or "/time-block"') with concrete trigger phrases, and 'what' (classifies, builds a schedule with hard constraints, batches, logs sessions). Both are explicit and concrete, matching the score-5 anchor; third-person voice is used throughout ('Classifies', 'builds', 'batches', 'logs').

Trigger Term Quality

Natural phrases users would say are comprehensively covered: 'plan a deep work day', 'time-block their calendar or task list', 'budget or cut shallow work', 'protect focus hours', 'track deep-work sessions and streaks', 'run an end-of-day shutdown ritual', plus explicit slash commands '/deep-work' and '/time-block'. This matches the score-5 anchor including synonyms and command variants.

Distinctiveness Conflict Risk

The deep-work/time-blocking niche is mostly distinct with specific triggers, but generic requests like 'plan my day' or 'organize my calendar' could overlap with general productivity or calendar skills, and the disambiguation from siblings (andreessen 3x5 card, project-management) lives in the body's 'Distinct From' section rather than the description. Matches 'mostly distinct; minor overlap risk' (4) rather than 5, which would require the description itself to carry the distinct triggers and boundaries.
