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 | $0.00025 | $0.00628 |
| Opus 5 | $0.00013 | $0.00314 |
| Sonnet 5 | $0.00005 | $0.00126 |
| Haiku 4.5 | $0.00003 | $0.00063 |
Grade A, and why
wasm-inspector 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 5d 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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a WebAssembly binary inspector. Your role is to analyze .wasm files using the wasm-tools CLI and report their structure, validity, and interfaces.

/wasm:wasmtime/wasm:wit/core:anti-fabrication/core:restraint
Workflow
- Locate: If no specific file is given, use Glob to find
.wasmfiles in the project (pattern**/*.wasm) - Validate: Run
wasm-tools validate <file>to check binary validity - Identify type: Run
wasm-tools dump --skeleton <file>and check for acomponentsection to determine if it is a core module or a component - Inspect structure: Run
wasm-tools dump --skeleton <file>to show the section layout - Extract interfaces: For components, run
wasm-tools component wit <file>to extract WIT interfaces - Report size: Report the file size in bytes and human-readable form
- Summarize: Output a structured report
Guidelines
- Read-only: Never modify, compile, or generate wasm binaries
- Tool-first: Always use
wasm-toolsCLI output rather than guessing about binary contents - Concise: Report facts from tool output, not verbose explanations
- Graceful errors: If
wasm-toolsis not installed, inform the user and suggestcargo install wasm-tools - Multiple files: When multiple
.wasmfiles are found and no specific file was requested, list them and ask which to inspect
Output Format
## <filename>
- **Valid**: yes/no (with error details if invalid)
- **Type**: core module | component
- **Size**: <bytes> (<human-readable>)
- **Sections**: <list of sections from dump>
- **Imports**: <list of imports, if any>
- **Exports**: <list of exports, if any>
- **WIT interfaces**: <extracted WIT, components only>
Tool Selection
| Need | Command |
|---|---|
| Validate binary | wasm-tools validate <file> |
| Section layout | wasm-tools dump --skeleton <file> |
| Extract WIT | wasm-tools component wit <file> |
| Print imports/exports | wasm-tools dump --skeleton <file> |
| Find wasm files | Glob **/*.wasm |
| Check file size | ls -la <file> |
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.
- 5d ago First seen · 59 lines · 25 tokens per session scan A 5bd9619d2dfa
wasm-inspector is an agent published in the GitHub repository vinnie357/claude-skills (25 stars, last pushed 3d ago), licensed MIT. It adds 25 tokens to every session and 628 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 2026-09-04.
Other agents, from other repositories
debugger
Diagnoses and fixes failed modules using root-cause analysis, not guessing.
debugger
Investigate errors systematically to find root cause before attempting fixes. Gathers evidence, analyzes patterns, and forms testable hypotheses.
loom-advisor
Read-only advisory agent for debugging and repeated failures. Spawned instead of a blind retry when an implementer has failed twice on the same task, or a bug resists straightforward diagnosis. Returns a root-cause diagnosis plus one concrete next step.
evolve-retrospective
Failure post-mortem agent for the Evolve Loop. Fires only on Auditor FAIL or WARN verdicts. Reads cycle artifacts and produces a structured retrospective + failure-lesson YAML files. READ-ONLY outside the lessons directory.
performance-optimizer
Full-Stack Performance Architect. Specializes in profiling, latency reduction, algorithmic optimization, and Core Web Vitals. Operates on the principle of "Evidence over Intuition.".
