What is stringer CLAUDE.md?

A set of project instructions for Stringer, covering Git work, secret handling, the Beads task backlog, and written records of important decisions.

It guides agents to use feature branches and pull requests, signed commits, secret checks, Beads issues, and decision records.

It keeps changes traceable and consistent, while reducing accidental direct pushes, leaked secrets, duplicate work, and forgotten tasks.

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	$0.01047	$0.01047
Opus 5.5	$0.00419	$0.00419
Sonnet 5.5	$0.00209	$0.00209
Haiku 4.5	$0.00105	$0.00105

Security

Grade A, and why

stringer 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.

CLAUDE.md — Stringer

Git Workflow

Always use PRs. Never push directly to main. Create a feature branch, commit, push, and open a PR with gh pr create.
Branch naming: <type>/<short-description> (e.g., feat/todo-collector, fix/config-loading)
Commit messages: conventional commits format (feat:, fix:, chore:, docs:, test:)
DCO sign-off required. Always use git commit -s (or --signoff) so every commit includes a Signed-off-by line. CI will reject commits without it.
Check for existing open PRs with gh pr list before creating new ones to avoid duplicates
Prefer adding commits to an existing open PR for related work

Secret Safety

Never commit secrets. The pre-commit hook runs gitleaks automatically.
If you get a gitleaks error, fix the issue — do not bypass with --no-verify.
New clones must run: git config core.hooksPath .githooks

Beads Backlog

Find work: bd ready --json
Before starting: claim an issue or create one with bd create
Reference issue ID in commits: feat: add scanner [stringer-bsf]
After PR merge: bd close <id> --reason "Completed in PR #N"

Decision Records

When a task involves choosing between approaches (libraries, patterns, formats, trade-offs), write a decision record before implementing.
Create docs/decisions/NNN-short-title.md using the template in AGENTS.md.
Set status to Proposed — do not implement until a developer accepts the decision.
Reference the beads issue ID in the record's Context field.

Build & Test

go build -o stringer ./cmd/stringer
go test -race ./...
golangci-lint run ./...

Current Focus

v1.11.0 released (2026-09-19) — benchmark-driven accuracy and performance release. All benchmark follow-ups (epics stringer-nxx, stringer-jfh, plus ds4, wmg) are closed through PR #461; the run of record is in docs/research/benchmark-2026-09.md and the README table.
CI hardening (in progress): nightly benchmark regression against pinned repos (stringer-umb), self-scan gate on new high-confidence findings (stringer-xb2), Windows/macOS test legs (stringer-ouz). Coverage artifact upload (stringer-td6) follows once the ci.yml change lands.
Decisions awaiting the owner: DR-019 (dephealth refactor; partly addressed by the registry worker pool in #451), DR-020 (AST interface-drift check; the current awk block comparison already covers most of it, see stringer-td7), DR-022 (opportunity axis; stringer-w1d not started).
Quick wins: P3/P4 unblocked tasks — run bd ready

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.
