function-trace-generator

function-trace-generator is an agent for Claude Code from gadievron/raptor. It costs 15 tokens per session (1,070 once invoked), scanned B, original, no licence file.

A tool that records which functions run during a program execution. The result is an execution trace for debugging and analysis.

In plain words
What is it for?
Use it to create function-level traces for debugging or studying program execution.
Why use it?

Token cost

What it costs to keep this loaded

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.

Security

Grade B, and why

function-trace-generator scanned grade B with 1 finding 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 17d 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

**Sandbox the untrusted build and run.** The target repository is untrusted — its build scripts execute arbitrary code. Run the target rebuild (step 2) and the crashing execution (step 3) via `libexec/raptor-run-sandboxe

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
