codex-subagent

Launch OpenAI Codex CLI as a subagent (ChatGPT subscription auth, no API key). Use when delegating a self-contained coding task to Codex from another agent — parallel implementation work, a second opinion, or an independent verification pass.

Quality

Content

85%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A tight, highly actionable skill body with executable commands, an explicit preflight validation checkpoint, and thorough failure-mode recovery. Its only weakness is a hardcoded, time-sensitive model-version pin repeated across sections.

Suggestions

Move the pinned model (gpt-5.6-sol) and reasoning-effort defaults into a single config note or a versioned/deprecated section so they don't age silently in two places.

In the Parallel runs example, reference the shared launch flags rather than repeating them verbatim to reduce redundancy.

Consider an explicit "only declare done after reviewing the diff" validation line in the Collect results section to make the feedback loop as crisp as the preflight one.

DimensionReasoningScore

Conciseness

Largely lean and operational, but it hardcodes a time-sensitive model pin ("Always use GPT 5.6 Sol (gpt-5.6-sol)") twice with no deprecated/old-patterns section, and the Parallel runs block repeats the same flags already shown in Launch.

2 / 3

Actionability

Provides complete, copy-paste-ready bash for preflight, launch, result collection, and parallel worktree runs — concrete commands with all required flags rather than pseudocode.

3 / 3

Workflow Clarity

Clear sequence (Preflight → Launch → Collect → Failure modes) with an explicit validation checkpoint ("codex login status" exit 0, stop if not logged in) and error-recovery guidance for hangs, login failures, and rate limits.

3 / 3

Progressive Disclosure

Self-contained single-file skill with no external references needed; content is well-organized into clearly signaled sections with no nested/deep references.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that concisely states the capability and gives an explicit, multi-trigger "Use when" clause. It is specific, natural-voiced, and clearly distinguishable from other skills.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "Launch OpenAI Codex CLI as a subagent", "parallel implementation work", "a second opinion", "independent verification" — rather than vague abstractions.

3 / 3

Completeness

Explicitly answers both what ("Launch OpenAI Codex CLI as a subagent") and when via an explicit "Use when delegating a self-contained coding task..." trigger clause.

3 / 3

Trigger Term Quality

Includes natural phrasing a user would actually say — "parallel implementation work", "a second opinion", "independent verification pass", "self-contained coding task" — with good coverage of variations.

3 / 3

Distinctiveness Conflict Risk

Scoped to a clear niche — Codex CLI as a subagent with ChatGPT-subscription auth — with distinct triggers unlikely to fire for unrelated skills.
