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.
npx agentmods add commands/jerrylalala/compound-engineering/silgit clone --depth 1 https://github.com/Jerrylalala/compound-engineeringWhat it costs to keep this loaded
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 | $0.00018 | $0.00762 |
| Opus 5 | $0.00009 | $0.00381 |
| Sonnet 5 | $0.00004 | $0.00152 |
| Haiku 4.5 | $0.00002 | $0.00076 |
Grade A, and why
sil 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 2d 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 — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/sil
Use this command when work in this repository changes any Claude-facing workflow behavior that must remain reflected in the Codex integration layer.
When To Use
Run /sil after any of these:
- changed
plugins/compound-engineering/commands/workflows/brainstorm.md - changed
plugins/compound-engineering/commands/workflows/plan.md - changed
plugins/compound-engineering/commands/workflows/review.md - changed shared document contract for
docs/brainstorms/ordocs/plans/ - changed the minimal Codex workflow sync script
- changed user-facing Codex workflow docs or README guidance
Do not use /sil for unrelated changes that do not affect the Codex mirror.
Goal
Keep the Codex-side workflow layer aligned without mutating Claude execution workflows into runtime-agnostic abstractions.
For this private fork, /sil means minimal Codex sync only. It does not mean reinstalling the full converted plugin into Codex.
Codex-owned layer:
.codex/skills/workflows-brainstorm/SKILL.md.codex/skills/workflows-plan/SKILL.md.codex/skills/workflows-review/SKILL.md
Shared contract and usage docs:
docs/specs/codex-workflow-compatibility.mddocs/zh-CN/CODEX-WORKFLOWS.mdREADME.md
Sync mechanism:
scripts/sync-codex-workflows.ps1
Procedure
- Read the current diff and identify whether the change affects:
- brainstorm behavior
- plan document structure
- review output expectations
- Codex installation or discovery
- Update the matching
.codexskill files. - If the shared document contract changed, update
docs/specs/codex-workflow-compatibility.mdfirst. - If local or installed usage changed, update
docs/zh-CN/CODEX-WORKFLOWS.mdandREADME.md. - Run exactly:
powershell -ExecutionPolicy Bypass -File scripts/sync-codex-workflows.ps1 - Verify only these three skills remain as top-level workflow entrypoints in
~/.codex/skills/:workflows-brainstormworkflows-planworkflows-review
- Report exactly what was synced and what was intentionally left unchanged.
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.

sil is a command published in the GitHub repository Jerrylalala/compound-engineering (5 stars, last pushed 3mo ago), licensed MIT. It adds 18 tokens to every session and 762 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.
