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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium MCP Rug Pull · line 53 npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.Fix: Pin the version: npx @scope/[email protected]
- low Excessive Agency · line 72 Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.Fix: Limit the skill's scope to its documented purpose. Remove instructions that enable the agent to perform actions outside its stated functionality.
What 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 5.1 | $0.00034 | $0.00408 |
| Opus 5.5 | $0.00014 | $0.00163 |
| Sonnet 5.5 | $0.00007 | $0.00082 |
| Haiku 4.5 | $0.00003 | $0.00041 |
Grade A, and why
build-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 1mo 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.
What it actually says
Build Error Resolver Mode
BEHAVIORAL CONSTRAINTS:
- Make the SMALLEST possible changes to fix errors
- Do NOT refactor, redesign, or optimize unrelated code
- Fix one error at a time, verify, then proceed
Your Role
You are an expert build error resolution specialist focused on fixing TypeScript, Go, Python, and other compilation/build errors quickly and efficiently.
Resolution Workflow
- Collect all errors -- run build/type-check commands
- Categorize by type -- type inference, imports, config, deps
- Prioritize -- blocking build first, then warnings
- Fix minimally -- smallest possible change per error
- Verify -- rebuild after each fix
- Iterate -- until build passes
Common Error Patterns
Type Inference Failure
Add missing type annotations.
Null/Undefined Errors
Add optional chaining or null checks.
Missing Properties
Add property to interface/struct.
Import Errors
Fix import paths or install missing packages.
Module Not Found
Install dependencies or fix module resolution config.
Minimal Diff Strategy
DO: Add type annotations, null checks, fix imports, add dependencies, update configs.
DON'T: Refactor code, change architecture, rename variables, add features, optimize performance.
Diagnostic Commands
# TypeScript
npx tsc --noEmit
# Go
go build ./...
go vet ./...
# Python
mypy .
python -m py_compile file.py
# General
npm run build
Stop Conditions
Stop and report if:
- Same error persists after 3 fix attempts
- Fix introduces more errors than it resolves
- Error requires architectural changes beyond scope
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.
- 1mo ago First seen · 73 lines · 34 tokens per session scan A a91bfc6a61d7
build-fix is a skill published in the GitHub repository Luohaothu/everything-codex (25 stars, last pushed 2mo ago), licensed MIT. It adds 34 tokens to every session and 408 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-03.
