What is code-pathfinder CLAUDE.md?

A project instruction file for Claude Code that documents how to build, test, lint, and run a Go-based code-analysis tool. It also lists commands for scanning projects and diagnosing analysis results.

Use it as a reference when compiling the binary, running Go tests or linting, starting the analysis server, scanning a project, running CI output, or investigating resolution and taint-analysis issues.

It gives Claude Code the repository context needed to run the right commands and understand the available operating modes. This reduces guesswork when building, testing, or troubleshooting the codebase.

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.

Model	Per session	Once invoked
Fable 5.1	$0.03473	$0.03473
Opus 5.5	$0.01389	$0.01389
Sonnet 5.5	$0.00695	$0.00695
Haiku 4.5	$0.00347	$0.00347

Security

Grade A, and why

code-pathfinder CLAUDE.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 1mo 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.

Essential Build Commands

Building the Binary

cd sast-engine
gradle buildGo

The binary is output to build/go/pathfinder. The build automatically cleans previous builds first.

Running Tests

gradle testGo          # Run all Go tests
go test ./...          # Direct Go test command
go test -v ./graph/... # Run tests for specific package with verbose output

Linting

gradle lintGo
# or directly:
golangci-lint run

Running the Binary

# MCP server mode (for AI coding assistants)
./build/go/pathfinder serve --project <path>
./build/go/pathfinder serve --http --address :8080 --project <path>

# Scan mode (using Python SDK rules)
./build/go/pathfinder scan --project <path> --ruleset <path_to_rules>

# CI mode (loads rules from remote/local, outputs SARIF/JSON/CSV)
./build/go/pathfinder ci --project <path> --ruleset cpf/java --output sarif

# Resolution diagnostics
./build/go/pathfinder resolution-report --project <path>

# Taint analysis diagnostics
./build/go/pathfinder diagnose --project <path>

Running a Single Test

go test -v -run TestBuildCallGraph ./graph/callgraph/builder/
go test -v -run TestTypeInference ./graph/callgraph/resolution/

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.
