Codex default deny skill staging

Skill whyy9527/codexception/examples/codex-default-deny-skill-staging

Add or rename Codex-native skills in a default-deny ~/.codex git repository. Use when new files under ~/.codex/skills appear untracked, hook scripts need .gitignore allowlisting, or Finder creates .DS_Store noise.From its SKILL.md

Codex Default-Deny Skill Staging

Use When

~/.codex/.gitignore starts with * and selectively allows curated config.
Adding a real Codex-native skill under ~/.codex/skills.
Adding a hook script under ~/.codex/hooks.
git status --short --untracked-files=all shows runtime noise next to the intended files.

Failure Mechanism

A default-deny config repo protects secrets and runtime state, but it also means new hook scripts or skill files may not be staged unless explicitly allowlisted. Broad staging can accidentally pick up runtime files if ignore rules are wrong.

Procedure

Read ~/.codex/.gitignore before staging.
Add precise allowlist rules for curated hook scripts or skill directories.
Keep runtime files ignored: auth.json, config.toml, sessions, logs, sqlite files, caches, and generated bridge wrappers.
Use explicit staging paths, for example:

git -C ~/.codex add .gitignore hooks.json hooks/codexception-activator.sh skills/codexception

Do not stage skills/.DS_Store or generated bridge symlinks.

Verification

git -C ~/.codex status --short --untracked-files=all
~/.codex/claude-bridge/validate.sh
Secret scan over staged candidates before commit.

High-Risk Actions

Do not use git add -A, git add ., or git commit -a in ~/.codex.
Do not track config.toml, auth.json, sessions, logs, sqlite databases, or generated bridge wrappers.
Do not shrink bridge allowlists just because this machine has stale links.
