Conciseness

Mostly efficient, Tessl-specific instruction with little generic padding, but a few passages could be trimmed: "Keep JSON valid: quote every key and string, no trailing commas, no comments" restates JSON basics, and Section 3's closing scope paragraph ("Checking every scheduled skill would require a platform launch-preflight hook and is outside this workflow") is justification Claude does not need to act. Not 3 because the bulk of the content (field rules, cap behavior, apply-time vs validate-time checks) is non-obvious and earns its place.

Actionability

Concrete, executable commands throughout (`tessl schedule --help`, `tessl env view --json --workspace <workspace> <environment>`, `tessl schedule validate`, `tessl schedule list --json --limit 100`) plus a complete JSON example and exact ref formats. Not 5 because Section 3 instructs copying provider scripts "verbatim and unmodified from this skill's `scripts/` directory" while no scripts/ directory exists in the bundle, and `tessl skill new` is named without showing its arguments. Not 3 because the guidance is otherwise copy-paste ready with specific error-recovery steps.

Workflow Clarity

A clearly sequenced seven-phase workflow (Preflight → Gather → Author → Choose key → Write → Validate → Explain next) with an explicit validation checkpoint and feedback loop: "Fix anything it reports and run it again until it passes", followed by a troubleshooting list for schedules that do not appear after push. Preflight checks (file existence, key collisions, current CLI surface) catch errors early.

Progressive Disclosure

The body is a decision workflow with the full field list and shorthand tables correctly split into two real, clearly signaled, one-level-deep references (references/schedules-block.md, references/cron-cadence.md), both of which exist in the bundle. Not 5 because the body also references "this skill's `scripts/` directory" (linear.sh, slack.sh, notion.sh) as the source for credential pre-flight scripts, and that directory does not exist in the bundle — a referenced path that cannot be resolved.

Specificity

Lists multiple concrete actions with comprehensive coverage: "Create a repo-defined schedule in a project's tessl.json", "optionally authoring the repo-local skill it runs", "chooses the most readable supported schedule format, adds and validates the entry, and explains what happens on push". Every stage of the task (create, author, format, add, validate, explain) is explicitly stated; nothing is left vague.

Completeness

Clearly answers both questions: the "what" is stated in the first sentence and elaborated concretely (choose format, add, validate, explain on push), and an explicit "Use when the user wants to schedule a skill to run on a recurring cadence..." clause gives concrete triggers. It even adds a "Not for..." boundary clause.

Trigger Term Quality

Includes literal quoted phrases users would naturally say ("run X every morning", "kick off the report nightly", "schedule this weekly") plus synonyms (schedule, cadence, recurring, nightly, weekly) and the concrete file target ("add a `schedules` block to tessl.json"). Coverage of natural terms is comprehensive for this domain.

Distinctiveness Conflict Risk

A clear niche (repo-defined schedules in tessl.json) with explicit routing away from adjacent skills: "Not for one-off runs (use `tessl launch`) or for moving an existing UI/CLI schedule into the file (use schedule-migrate)". Minimal risk of triggering for the wrong skill.
