The body is mostly efficient and free of concepts Claude already knows, but Codex-priming guidance is restated across three sections ("Mental Model", the "Codex posture" entry in "Prompt Contents", and the dedicated "Codex Posture" section), and "What To Avoid" / "Stop Condition" overlap with earlier watch-out and proof/stop content, so it could be tightened.

It gives concrete, copy-paste-ready templates: grounding bash commands (git status --short --branch, git diff --name-status), a labeled Prompt Contents block, and specific Candidate Codex seam shapes with exact inputs and result-packet fields, plus explicit rules like "one job, bounded sources, one deliverable, clear stop condition".

The sections imply a sequence (Ground Before Writing -> Prompt Contents -> Codex Posture -> Stop Condition) and give an explicit stop condition, but there are no explicit validation or verification checkpoints in the drafting workflow itself, matching the "sequence present but checkpoints missing or implicit" anchor rather than the validation-loop anchor above.

No bundle files exist (references/, scripts/, assets/ all empty) and the skill is a self-contained instruction document organized into well-labeled sections (One Sentence, Mental Model, Ground Before Writing, Prompt Contents, Codex Posture, What To Avoid, Stop Condition) with a single clearly-signaled one-level cross-skill reference ([agent-goal](../agent-goal/SKILL.md)) and no nested references.

It names multiple concrete actions and the artifact produced — "Draft a compact, cold-start prompt to paste into Claude Code, with Claude as orchestrator and Codex available through /codex:rescue for bounded evidence gathering, focused implementation, commands, verification, cleanup, and creative support" — matching the "lists multiple specific concrete actions" anchor; it is not the level below because it goes well beyond naming only a domain and a few actions.

It explicitly answers both what (drafting a compact cold-start handoff prompt with Claude as orchestrator and Codex via /codex:rescue) and when (an explicit "Use when the user says ..." clause with many triggers), matching the "clearly answers both what AND when with explicit triggers" anchor; it is not the level below because the 'when' is explicit, not merely implied.

It includes a rich set of natural phrases a user would actually say ("hand this off", "wrap up for the next session", "resume this later", "continue in a new chat", "write a continuation prompt", "make a prompt I can copy-paste", "create a delegation brief") plus the /handoff invocation, giving good coverage of natural trigger terms rather than just a few relevant keywords.

It carves out a clear niche and explicitly disambiguates from adjacent skills — "Not for /goal lines (use agent-goal) or prompts that ship inside product code" — with distinct triggers, making it unlikely to fire for the wrong skill; it is not the level below because it actively excludes overlap rather than remaining only somewhat specific.
