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 5.1 | $0.02502 | $0.02502 |
| Opus 5 | $0.01251 | $0.01251 |
| Sonnet 5 | $0.00500 | $0.00500 |
| Haiku 4.5 | $0.00250 | $0.00250 |
Grade A, and why
scout 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 6d 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 This Is
scout is a Gin-like browser automation library for Go using a pure Chrome DevTools Protocol (CDP) implementation over WebSocket. No rod, no chromedp. It has two API layers: a core browse package (Engine/Context/Group/HandlerFunc for developers) and an agent package (Session-based, structured-output API for AI agents). Includes an MCP server binary at cmd/scout and a conversational browser UI at cmd/scout ui serve.
Commands
# Build & verify
go build ./...
go vet ./...
golangci-lint run --timeout 5m ./... # examples/ excluded via .golangci.yml
# Tests (Chrome required for integration tests; integration suites are
# behind the `integration` build tag, so the default run is unit-only)
go test ./... # unit tests only, no Chrome
go test -tags integration ./... # all tests (unit + integration)
go test -tags integration -run TestIntegrationClick ./... # single test
go test -tags integration -run TestIntegration -timeout 600s ./... # all integration tests
go test -tags integration -v -race -timeout 600s ./agent/... # agent package with race detector
# Coverage
make cover-check # runs tests + coverctl policy enforcement
# Pre-commit hook (gofmt, vet, lint, unit tests, coverctl, nox baseline)
make hooks # install
bash scripts/pre-commit.sh # run manually
# AG-UI server (conversational browser UI)
scout ui serve --provider=ollama --model=mistral # local LLM
scout ui serve --provider=claude # Claude (needs ANTHROPIC_API_KEY)
scout ui serve --provider=openai # OpenAI (needs OPENAI_API_KEY)
cd ui && npm install && npm run dev # Vue frontend at :3000
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.

scout CLAUDE.md is an instructions file published in the GitHub repository klarlabs-studio/scout (11 stars, last pushed 2d ago), licensed MIT. It adds 2,502 tokens to every session, about $0.0125 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 2026-08-31.
