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 | $0.00047 | $0.00571 |
| Opus 5 | $0.00023 | $0.00285 |
| Sonnet 5 | $0.00009 | $0.00114 |
| Haiku 4.5 | $0.00005 | $0.00057 |
Grade A, and why
wasm-module-inspect 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 10d 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
WASM Module Inspect
Inspect a compiled .wasm binary to verify it is valid, understand its public API surface, and detect compilation features (SIMD, threads).
Requirements
- wabt (
wasm-validate,wasm2wat) — install viabrew install wabt(macOS),apt install wabt(Linux), or from https://github.com/WebAssembly/wabt/releases - wasm-opt (optional, Binaryen) — install via
brew install binaryenfor feature reporting
Instructions
The argument is in $ARGUMENTS. Pass it directly to the inspection script:
bash "$(dirname "$0")/inspect.sh" $ARGUMENTS
Output sections
| Section | What it reports |
|---|---|
SIZE |
Binary size in bytes and KB |
VALID |
Pass/fail from wasm-validate |
EXPORTS |
All exported functions, memories, tables, globals |
IMPORTS |
All imported functions (JS host functions the module depends on) |
SIMD |
Whether v128 (WASM SIMD) opcodes are present |
THREADS |
Whether atomic instructions are present (requires SharedArrayBuffer) |
FEATURES |
Full feature list from wasm-opt --print-features (if available) |
Typical usage
# After an Emscripten build — confirm exports match expected API
bash inspect.sh build/my-dsp.wasm
# Before deploying — confirm SIMD is present in the optimised build
bash inspect.sh dist/processor.wasm
What to look for
- Exports should be minimal — only the functions the JS/worklet layer calls (e.g.
_init,_process,_destroy). Unexpected exports indicate-s EXPORTED_FUNCTIONSwas not set correctly. - SIMD present confirms
-msimd128was applied and the WASM binary actually contains vectorised code. - Threads present means the page must be served with
COOP/COEPheaders — flag this if the deployment environment does not support them. - Large binary size may indicate the Emscripten filesystem (
-s FILESYSTEM=0not set) or C++ RTTI/exceptions were not disabled.
What ships with it
1 file 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.

wasm-module-inspect is a skill published in the GitHub repository gertsylvest/meta-team (5 stars, last pushed 1mo ago), licensed MIT. It adds 47 tokens to every session and 571 once invoked, about $0.0002 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.
