Teknium 9f1b1977bc docs(skills): salvage dropped trigger content into skill bodies
For 14 of 74 compressed skills, the original description contained
trigger keywords, technique counts, attribution, or use-case phrases
not covered by the existing body content. Prepends a 'When to use' /
'What's inside' block near the top so the agent still has the full
context when the skill is loaded.

Skills salvaged:
- codex, ascii-video, creative-ideation, excalidraw, manim-video, p5js
- gif-search, heartmula, youtube-content
- lm-evaluation-harness, obliteratus, vllm, axolotl
- powerpoint

Remaining 60 skills were verified to already cover the dropped content
in their existing body sections (When to Use, overview, intro prose)
or had short descriptions fully captured by the new compressed form.

# Codex CLI
Delegate coding tasks to [Codex](https://github.com/openai/codex) via the Hermes terminal. Codex is OpenAI's autonomous coding agent CLI.
## When to use
- Building features
- Refactoring
- PR reviews
- Batch issue fixing
Requires the codex CLI and a git repository.
## Prerequisites
- Codex installed: `npm install -g @openai/codex`
- OpenAI API key configured
- **Must run inside a git repository** — Codex refuses to run outside one
- Use `pty=true` in terminal calls — Codex is an interactive terminal app
## One-Shot Tasks
```
terminal(command="codex exec 'Add dark mode toggle to settings'", workdir="~/project", pty=true)
```
For scratch work (Codex needs a git repo):
```
terminal(command="cd $(mktemp -d) && git init && codex exec 'Build a snake game in Python'", pty=true)
```
## Background Mode (Long Tasks)
```
# Start in background with PTY
terminal(command="codex exec --full-auto 'Refactor the auth module'", workdir="~/project", background=true, pty=true)
# Returns session_id
# Monitor progress
process(action="poll", session_id="<id>")
process(action="log", session_id="<id>")
# Send input if Codex asks a question
process(action="submit", session_id="<id>", data="yes")
# Kill if needed
process(action="kill", session_id="<id>")
```
## Key Flags
| Flag | Effect |
|------|--------|
| `exec "prompt"` | One-shot execution, exits when done |
| `--full-auto` | Sandboxed but auto-approves file changes in workspace |
| `--yolo` | No sandbox, no approvals (fastest, most dangerous) |
## PR Reviews
Clone to a temp directory for safe review:
```
terminal(command="REVIEW=$(mktemp -d) && git clone https://github.com/user/repo.git $REVIEW && cd $REVIEW && gh pr checkout 42 && codex review --base origin/main", pty=true)
```
## Parallel Issue Fixing with Worktrees
```
# Create worktrees
terminal(command="git worktree add -b fix/issue-78 /tmp/issue-78 main", workdir="~/project")
terminal(command="git worktree add -b fix/issue-99 /tmp/issue-99 main", workdir="~/project")
# Launch Codex in each
terminal(command="codex --yolo exec 'Fix issue #78: <description>. Commit when done.'", workdir="/tmp/issue-78", background=true, pty=true)
terminal(command="codex --yolo exec 'Fix issue #99: <description>. Commit when done.'", workdir="/tmp/issue-99", background=true, pty=true)
# Monitor
process(action="list")
# After completion, push and create PRs
terminal(command="cd /tmp/issue-78 && git push -u origin fix/issue-78")
terminal(command="gh pr create --repo user/repo --head fix/issue-78 --title 'fix: ...' --body '...'")
# Cleanup
terminal(command="git worktree remove /tmp/issue-78", workdir="~/project")
```
## Batch PR Reviews
```
# Fetch all PR refs
terminal(command="git fetch origin '+refs/pull/*/head:refs/remotes/origin/pr/*'", workdir="~/project")
# Review multiple PRs in parallel
terminal(command="codex exec 'Review PR #86. git diff origin/main...origin/pr/86'", workdir="~/project", background=true, pty=true)
terminal(command="codex exec 'Review PR #87. git diff origin/main...origin/pr/87'", workdir="~/project", background=true, pty=true)
# Post results
terminal(command="gh pr comment 86 --body '<review>'", workdir="~/project")
```
## Rules
1. **Always use `pty=true`** — Codex is an interactive terminal app and hangs without a PTY
2. **Git repo required** — Codex won't run outside a git directory. Use `mktemp -d && git init` for scratch
3. **Use `exec` for one-shots**`codex exec "prompt"` runs and exits cleanly
4. **`--full-auto` for building** — auto-approves changes within the sandbox
5. **Background for long tasks** — use `background=true` and monitor with `process` tool
6. **Don't interfere** — monitor with `poll`/`log`, be patient with long-running tasks
7. **Parallel is fine** — run multiple Codex processes at once for batch work
