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.
npx agentmods add instructions/adobe/spacecat-api-service/claude-mdgit clone --depth 1 https://github.com/adobe/spacecat-api-serviceWhat 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 | $0.07859 | $0.07859 |
| Opus 5 | $0.03929 | $0.03929 |
| Sonnet 5 | $0.01572 | $0.01572 |
| Haiku 4.5 | $0.00786 | $0.00786 |
Grade A, and why
spacecat-api-service 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 2d 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.
How it starts

Commands
Development
npm start # Start development server with hot reload
npm test # Run unit tests (excludes Post-Deploy tests)
npm run test:bundle # Test production bundle
npm run test-postdeploy # Run post-deployment tests
npm run test-e2e # Run end-to-end tests (30s timeout)
npm run lint # Run ESLint
npm run lint:fix # Auto-fix linting issues
npm run type-check # Both tiers below; blocking gate in CI and pre-commit
npm run type-check:base # Opt-in tsc --checkJs over // @ts-check files (serenity)
npm run type-check:strict # noImplicitAny over the strict file list (see tsconfig.strict.json)
Single Test Execution
npx mocha test/path/to/specific.test.js # Run single test file
npx mocha test/path/to/specific.test.js -g "pattern" # Run tests matching pattern
Integration Tests
# PostgreSQL suite (requires Docker + ECR access)
npx mocha --require test/it/postgres/harness.js --timeout 30000 'test/it/postgres/**/*.test.js'
# Single IT test file
npx mocha --require test/it/postgres/harness.js --timeout 30000 test/it/postgres/sites.test.js
# Mock-backed suites (e.g. serenity, which drives the Semrush vendor mock
# containers over real HTTPS — not in-process stubs, no live Semrush) are slower
# than the pure-DB suites — run them with --timeout 60000:
npx mocha --require test/it/postgres/harness.js --timeout 60000 test/it/postgres/serenity.test.js
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.
