Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00028 | $0.01976 |
| Opus 5 | $0.00014 | $0.00988 |
| Sonnet 5 | $0.00006 | $0.00395 |
| Haiku 4.5 | $0.00003 | $0.00198 |
Grade A, and why
ce:setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Compound Engineering Setup
Interaction Method
Ask the user each question below using the platform's blocking question tool: AskUserQuestion in Claude Code (call ToolSearch with select:AskUserQuestion first if its schema isn't loaded), request_user_input in Codex, ask_user in Gemini, ask_user in Pi (requires the pi-ask-user extension). Fall back to presenting each question as a numbered list in chat only when no blocking tool exists in the harness or the call errors (e.g., Codex edit modes) — not because a schema load is required. Never silently skip or auto-configure. For multiSelect questions, accept comma-separated numbers (e.g. 1, 3).
Interactive setup for compound-engineering — diagnoses environment health, cleans obsolete repo-local CE config, and helps configure required tools. Review agent selection is handled automatically by ce-code-review; project-specific review guidance belongs in CLAUDE.md or AGENTS.md.
Phase 1: Diagnose
Step 1: Determine Plugin Version
Detect the installed compound-engineering plugin version by reading the plugin metadata or manifest. This is platform-specific -- use whatever mechanism is available (e.g., reading plugin.json from the plugin root or cache directory). If the version cannot be determined, skip this step.
If a version is found, pass it to the check script via --version. Otherwise omit the flag.
Step 2: Run the Health Check Script
Before running the script, display: "Compound Engineering -- checking your environment..."
Run the bundled check script from the installed skill directory, not from the user's current project. Resolve the skill directory first from the harness-provided skill path/root when available; in Claude Code, use the loaded skill base directory. If the harness cannot expose a skill directory, locate the installed ce-setup skill directory before running the script.
bash "$CE_SETUP_SKILL_DIR/scripts/check-health" --version VERSION
Or without version if Step 1 could not determine it:
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ce:setup is a skill published in the GitHub repository Jerrylalala/compound-engineering (5 stars, last pushed 3mo ago), licensed MIT. It adds 28 tokens to every session and 1,976 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
