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 | $0.00064 | $0.00362 |
| Opus 5 | $0.00032 | $0.00181 |
| Sonnet 5 | $0.00013 | $0.00072 |
| Haiku 4.5 | $0.00006 | $0.00036 |
Grade A, and why
frida-trace 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 4d 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
Frida API Tracer
⚡ Dynamic tier — Frida spawns and runs the target. Run only where you don't mind the risk.
When to use
You want the API/library view of a running sample — which network/exec/file/crypto
functions it actually calls — even when the code is statically obfuscated. Complements
syscall-trace (kernel view) with instrumentation at the library boundary.
What it does
Runs frida-trace with a curated set of hooks (network, exec,
file, crypto globs — override with --patterns), spawns the target, and logs the
matched calls for a bounded duration, then summarizes call counts per function.
Consent & prerequisites
- Dynamic:
rekit run --allow-dynamic frida-trace <target>(or--yes-i-consent/REKIT_ALLOW_DYNAMIC=1). frida-traceon PATH —pip install frida-tools(pulls the Frida native core). Absent →doctormarks it not-ready.
Usage
rekit run --allow-dynamic frida-trace ./sample --patterns "connect*,send*,open*"
rekit run --allow-dynamic frida-trace ./sample --format json
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.

frida-trace is a skill published in the GitHub repository batteryshark/rekit (11 stars, last pushed 26d ago), licensed Apache-2.0. It adds 64 tokens to every session and 362 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 2026-08-30.
