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 | $0.00024 | $0.00703 |
| Opus 5.5 | $0.00010 | $0.00281 |
| Sonnet 5.5 | $0.00005 | $0.00141 |
| Haiku 4.5 | $0.00002 | $0.00070 |
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.

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build and Fix (CDD Mode)
Incrementally fix build and type errors with minimal, safe changes. CDD 原则：编译失败时必须调用 sequential-thinking 分析，禁止盲目试错。
Step 1: Detect Build System
Identify the project's build tool and run the build:
| Indicator | Build Command |
|---|---|
package.json with build script |
npm run build or pnpm build |
tsconfig.json (TypeScript only) |
npx tsc --noEmit |
Cargo.toml |
cargo check 2>&1 |
pom.xml |
mvn compile |
build.gradle |
./gradlew compileKotlin |
go.mod |
go build ./... |
pyproject.toml |
pyright . or mypy . |
*.csproj / *.sln |
dotnet build --no-restore |
CMakeLists.txt |
cmake --build build/ |
*.uproject |
UnrealBuildTool |
Step 2: Parse and Group Errors
- Run the build command and capture stderr
- Group errors by file path
- Sort by dependency order (fix imports/types before logic errors)
- Count total errors for progress tracking
Step 3: Fix Loop (CDD Mode — Think Before Fix)
For each error:
- Read the file — Use Read tool to see error context (10 lines around the error)
- Think first — Invoke
sequential-thinkingMCP to analyze root cause (禁止盲目试错) - Diagnose — Identify root cause (missing import, wrong type, syntax error)
- Fix minimally — Use Edit tool for the smallest change that resolves the error
- Re-run build — Verify the error is gone and no new errors introduced
- Move to next — Continue with remaining errors
Step 4: Guardrails
Stop and ask the user if:
- A fix introduces more errors than it resolves
- The same error persists after 3 attempts (likely a deeper issue)
- The fix requires architectural changes (not just a build fix)
- Build errors stem from missing dependencies (need
npm install,cargo add, etc.)
Step 5: Summary
Show results:
- Errors fixed (with file paths)
- Errors remaining (if any)
- New errors introduced (should be zero)
- Suggested next steps for unresolved issues
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-fix is a command published in the GitHub repository zhmxiaowo/opencode-simple (2 stars, last pushed 7mo ago), licensed MIT. It adds 24 tokens to every session and 703 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 2026-08-31.
