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 5.1 | $0.00053 | $0.00623 |
| Opus 5 | $0.00026 | $0.00311 |
| Sonnet 5 | $0.00011 | $0.00125 |
| Haiku 4.5 | $0.00005 | $0.00062 |
Grade A, and why
senmu-build-engineering 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 — 36 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Software Engineering
Use project rules first; continue for missing, conflicting, changing, or explicitly reviewed engineering contracts.
Route by Outcome
- Quality, defects, AI collaboration, review: Source Quality.
- Technology/framework/component choice: Technology Selection.
- Minimum correct implementation, reuse, overengineering: Implementation Economy.
- Architecture, dependencies, change budgets, debt: Architecture.
- Frontend state, navigation, forms, responsive/browser checks: Frontend.
- APIs, services, data, transactions, caches, queues, jobs: Backend.
- Test strategy, doubles, dependencies, data, flakiness: Testing.
- Source modernization or stack upgrades: Modernization.
- Derive rules from an existing codebase: Discovery.
- Only if local rules are absent/under review: Python, TypeScript, Go, Java, Ant Design, HTML/daisyUI.
Read matched references only; one profile does not imply others. Frontend/backend are references, not child skills or job roles.
Fast Path
Engineering alone handles a reversible, contract-preserving G1 change with one owner. Add no skills, PRD, ADR, or changelog. Follow Kernel isolation, proportional verification, and local commit. Check open-batch items narrowly; consolidate after test intent. Exclude security, privacy, permissions, payments, production data, paid/destructive actions, and releases.
What ships with it
27 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.

senmu-build-engineering is a skill published in the GitHub repository SenMuShare/senmu-buildos (2 stars, last pushed 3d ago), licensed Apache-2.0. It adds 53 tokens to every session and 623 once invoked, about $0.0003 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.
Other skills, from other repositories
openproject-codex
Use the OpenProject Codex plugin to inspect and manage work in Codex through the OpenProject API.
ambient-project
Quietly maintain a useful project view from meaningful work in the current Codex session. Use when work creates a task, bug, decision, idea, risk, milestone, plan, progress update, or explicit completion.
mindtrain
Configure a private MindTrain instance, query its knowledge catalog, create user-approved training domains and knowledge points from AI dialogue or local reference libraries, and run persistent conversational training through Trainer MCP. Use when the user configures MindTrain, asks what domains or topics exist…
use-wsl
Use one wslexec call per user-requested non-interactive Linux execution when Windows-native Codex needs WSL. Preserve the project working directory and never probe or retry automatically.
zcode-delegate
Delegate a coding task to the Z.AI ZCode CLI as a background implementer, then review its diff and land it yourself. Use this whenever the user wants to hand implementation work to ZCode — phrasings like "have ZCode do X", "delegate this to ZCode", "run it through ZCode", or "use ZCode to implement/fix/refactor" — or…

File sentinel that monitors the working directory for changes and marker comments, then auto-triggers appropriate skills. Poll-based via git diff against the last scan commit. Writes intake items for batch processing and routes marker actions through /do. Use for automatic reactions to file changes; do NOT use for…
