codex-expo-run-actions

Wire Expo projects into the Codex app with project-local run scripts and .codex/environments/environment.toml actions. Use when the user wants the Codex app Run button, build/run actions, action buttons, or a stable Expo start/run workflow from Codex.

Quality

Content

86%Weight 40%Scale 1-5

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

A well-organized, lean skill body with a clear numbered workflow, concrete actionable details, and excellent progressive disclosure through one real reference file. The main improvement is adding an explicit error-recovery feedback loop for the validation step.

Suggestions

Add an explicit feedback loop for the syntax sanity-check (e.g., 'If `bash -n` or `--help` fails, fix the script and re-run before wiring the environment action') to lift workflow_clarity to 5.

Inline a minimal copy-paste version of the build_and_run.sh script header or the environment.toml Run action snippet directly in the body so the skill is fully executable without opening the reference.

Consider a brief one-line note clarifying when to add the optional platform-specific action buttons beyond 'when the user asks' (e.g., project already has native folders) to reduce ambiguity.

DimensionReasoningScore

Conciseness

Lean, action-only prose (~65 lines) that assumes Claude's competence — no padding or explaining of what Expo/Metro are; every section earns its tokens.

5 / 5

Actionability

Provides concrete file paths, exact mode flags, detection rules, and TOML action names; full copy-paste script lives in the reference rather than inline, leaving minor gaps in the body itself.

4 / 5

Workflow Clarity

A clearly sequenced 5-step workflow with conditional logic and a syntax sanity-check step, but lacks an explicit validate->fix->retry feedback loop that would reach the top anchor.

4 / 5

Progressive Disclosure

A concise overview pointing to a single, well-signaled, one-level-deep reference file that actually exists, with content appropriately split for easy navigation.

Description

87%Weight 40%Scale 1-5

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, well-structured description that clearly states both the capability and explicit trigger conditions, with natural user-facing keywords and a distinct niche. Minor room to broaden trigger-term synonyms and action coverage to fully reach comprehensive.

DimensionReasoningScore

Specificity

Names the domain (Expo + Codex) and several concrete actions (project-local run scripts, environment.toml actions, Run button) with only minor gaps in coverage, fitting the anchor between several-specific-actions and comprehensive.

4 / 5

Completeness

Explicitly answers both what ('Wire Expo projects into the Codex app with project-local run scripts and .codex/environments/environment.toml actions') and when ('Use when the user wants the Codex app Run button...') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Includes natural trigger phrases a user would say ('Codex app Run button', 'build/run actions', 'action buttons', 'stable Expo start/run workflow') with good coverage, though a few synonyms are missing.

4 / 5

Distinctiveness Conflict Risk

The combination of 'Codex app', 'Expo', and 'Run button' forms a clear, distinct niche with minimal overlap risk against other skills.
