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 | $0.04461 | $0.04461 |
| Opus 5.5 | $0.01784 | $0.01784 |
| Sonnet 5.5 | $0.00892 | $0.00892 |
| Haiku 4.5 | $0.00446 | $0.00446 |
Grade A, and why
funcfinder AGENTS.md 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 today.
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 — 448 lines — stays where its author put it; the contents beside it link to each section on GitHub.
funcfinder for AI Agents
Quick Reference: Map codebases, extract functions, trace calls, save 99% tokens.
Build First!
./build.sh # Required before first use (~5 sec)
Builds 5 binaries: funcfinder, funcstats, deps, complexity, callgraph.
Releases
-
1.16.1 adds Goose to all five Go tools; docs/GOOSE.md owns the supported profile. Standalone compressors live in the separate lz78-goose repository; retain only tooling fixtures/evaluators here.
-
VERSIONis the version source for local build scripts and release tags; record user-visible changes in rootCHANGELOG.md. -
Verify the integrated release revision with tests, builds and CI before publishing
v<VERSION>. Keep parser measurement limits in release notes. -
.github/workflows/release.ymlbuilds all five tools for Linux/macOS amd64/arm64 and Windows amd64 on tag push, checks the version file, and publishes archives pluschecksums.txt. Verify the workflow and assets. -
Keep generated Go harnesses outside the source module or isolated by an ignored
build/go.mod; fullgo test ./...must enumerate project packages only. Tests of module discovery require TMP/TEMP outside every Go module.
The Toolkit at a Glance
| Tool | Purpose | Input |
|---|---|---|
funcfinder |
Map functions & types, extract bodies | file or dir |
deps |
Import dependencies + shard graph | dir |
callgraph |
Who calls whom | file or dir |
funcstats |
File statistics (LOC, comments, imports), call frequency & hotspots | file |
complexity |
Cognitive complexity per function | file |
Investigation Workflow
Small project (< 50 files)
# 1. Orient — full map in one shot (~30ms)
funcfinder --dir . --all --json > map.json
# 2. Find the target
grep -i "auth" map.json
# → auth/handler.go:42: AuthenticateUser
# 3. Extract the body
funcfinder --inp auth/handler.go --source go --func AuthenticateUser --extract
# 4. Trace who it calls
callgraph --inp auth/handler.go -l go --func AuthenticateUser
# 5. Trace who calls it (impact)
callgraph --dir . -l go --reverse --func AuthenticateUser
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.

funcfinder AGENTS.md is an instructions file published in the GitHub repository ruslano69/funcfinder (2 stars, last pushed today), licensed MIT. It adds 4,461 tokens to every session, about $0.0178 per session on Opus 5.5. 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.
