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 | $0.00043 | $0.00373 |
| Opus 5 | $0.00022 | $0.00187 |
| Sonnet 5 | $0.00009 | $0.00075 |
| Haiku 4.5 | $0.00004 | $0.00037 |
Grade A, and why
build-and-fix 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 8d 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.
This is a copy
100% identical to build-and-fix — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Build and Fix Loop
Purpose
An autonomous loop for the agent to identify, analyze, and fix build errors using pnpm build.
Loop Logic
- Identify: Run
pnpm buildto identify build failures. - Analyze: Examine the build output to determine:
- The failing package and file.
- The specific compiler or build error message.
- Refer to ../common-references/troubleshooting.md for common TS errors.
- Fix: Apply the minimum necessary change to resolve the error (e.g., fixing TypeScript types, correcting imports, or updating configurations).
- Verify: Re-run
pnpm build.- If passed: Finish.
- If failed: Analyze the new failure and repeat the loop.
Termination Criteria
- The project builds successfully (as reported by
pnpm build). - Reached max iteration limit (default: 5).
- The error persists after multiple distinct fix attempts, indicating a need for human intervention.
Examples
Scenario: Fixing a TypeScript compilation error
pnpm buildfails because of a type mismatch inpackages/common/src/index.ts.- Agent analyzes the error and finds an incorrect interface implementation.
Resources
- pnpm Commands for Node.js: Common commands for building and managing dependencies.
- TypeScript Documentation: Official documentation for TypeScript.
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.

build-and-fix is a skill published in the GitHub repository yu-iskw/coding-agent-fabric (1 stars, last pushed 7d ago), licensed Apache-2.0. It adds 43 tokens to every session and 373 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to build-and-fix, differing in 0 lines, and is treated as a copy.
