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 | $0.00054 | $0.00928 |
| Opus 5 | $0.00027 | $0.00464 |
| Sonnet 5 | $0.00011 | $0.00186 |
| Haiku 4.5 | $0.00005 | $0.00093 |
Grade A, and why
faust-header-gen 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.
How it starts
The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Faust Header Gen
Read a Faust-generated C file and produce a matching extern "C" header. Eliminates the manual step of writing and maintaining a synth.h, which was historically a source of errors whenever the Faust class name (-cn) changed or new functions were added.
Requirements
- Python 3.8+
Instructions
Arguments are in $ARGUMENTS. Pass them directly to the generator:
python3 "$(dirname "$0")/gen_header.py" $ARGUMENTS
What the generated header contains
| Element | Detail |
|---|---|
| Include guard | #ifndef CLASSNAME_H / #define CLASSNAME_H (or custom via --guard) |
FAUSTFLOAT default |
#ifndef FAUSTFLOAT / #define FAUSTFLOAT float guard so the header can be included without the generated C |
| Dependency note | Comment stating faust/gui/CInterface.h must be included before this header (it defines UIGlue, MetaGlue, FAUSTFLOAT) |
extern "C" wrapping |
Guarded by #ifdef __cplusplus so the header works for both C and C++ consumers |
| Opaque forward declaration | typedef struct ClassName ClassName; — declares a named struct tag even though the generated C uses an anonymous struct typedef. This is the correct pattern for C++ consumers who hold only opaque pointers. |
| Public function prototypes | All non-static functions whose names end with the class name, grouped into: Lifecycle, Metadata, Query, Initialisation, User Interface, DSP |
RESTRICT stripped |
The generated C uses RESTRICT on parameter declarations. Headers omit it — restrict is an optimisation hint, not a type qualifier that affects linkage. |
void on zero-arg functions |
newSynth() in the generated C becomes newSynth(void) in the header — correct C for "no arguments". |
Options
| Option | Default | Description |
|---|---|---|
-o FILE |
stdout | Write header to file instead of stdout |
--guard NAME |
CLASSNAME_H |
Override the include guard name |
--exports FILE |
— | Also write a linker exports file (one _symbol per line, for .exp dylib builds) |
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.

faust-header-gen is a skill published in the GitHub repository gertsylvest/meta-team (5 stars, last pushed 1mo ago), licensed MIT. It adds 54 tokens to every session and 928 once invoked, about $0.0003 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.
