Conciseness

The body is a lean, directive bullet list with no padding or explanation of known concepts — every bullet is an instruction. Not 5 because the worktree/suggested-mode rule and preserve-fields rule each repeat across Workflow, Constraints, Execution Boundaries, and Gotchas, which could be consolidated.

Actionability

Concrete, executable directives for an instruction-only skill: "Resolve existing automations first by id, name, prompt, and local TOML evidence", the heartbeat-vs-cron routing rule, and "Use suggested create/update when proposing worktree automations with a non-null local environment setup config". Not 5 because no tool request shapes are shown inline; the concrete examples are delegated to references/tool-examples.md rather than covering common cases in the main file.

Workflow Clarity

The Workflow section sequences goal confirmation, existing-automation resolution, field mapping, preflight/rollback definition, then validation, and the Validation section supplies an explicit feedback loop: "Run the smallest command or test that exercises the changed behavior" and "Fail fast: stop at first failed gate; do not proceed until it is fixed and rerun". The Failure Mode section adds error-recovery paths, matching the top anchor.

Progressive Disclosure

The Progressive Disclosure section clearly signals four one-level-deep references (contract.yaml, tool-examples.md, evals.yaml, task-profile.json), each labeled with its purpose, and all four exist in the bundle. Not 5 because the fifth pointer, "Infrastructure/references/deferred-skill-context/agent-ops-codex-automation-architect/", does not resolve within the skill bundle, leaving a dangling external path.

Specificity

"designing, reviewing, or updating Codex app automations" names the domain and several specific actions, matching the 'several specific actions; minor gaps' anchor. Not 5 because coverage is incomplete: the body's consolidation, preflight, and validation work is absent from the description; not 3 because three distinct concrete verbs go beyond 1-2 actions.

Completeness

The explicit "Use when..." trigger clause is present, but the description consists solely of the when-clause; the what (what the skill does or produces) is only implied by the embedded verbs rather than stated separately. Not 2 because the verbs do convey concrete capability; not 4/5 because there is no distinct what-statement as in the anchor examples.

Trigger Term Quality

"cron jobs, scheduled tasks, recurring runs, heartbeat follow-ups" gives comprehensive natural-term coverage with multiple synonyms for the domain (cron/scheduled/recurring/heartbeat), plus the core "automations" term. No common user phrasing for this domain is missing.

Distinctiveness Conflict Risk

The "Codex app" qualifier carves a clear niche with mostly distinct triggers. Not 5 because the unqualified "cron jobs" and "scheduled tasks" terms carry minor overlap risk with generic OS/crontab or CI scheduling requests that are not Codex app automations.
