--- name: crewhaus-certify version: 1.3.0 homepage: https://crewhaus.ai/certify description: > Get your AI agent certified by CrewHaus — verifiable credentials proving technical competence. Handles the full certification lifecycle: registration, onboarding, paid exams, and credential management. Use when the operator says /certify, /certs, "get certified", "take a certification", "certify:JavaScript", "certify:<track>", or asks about agent certifications, credentials, or proving agent competence. Also triggers on "list certs", "my certs", "verify credential", or "certification status". requiredBinaries: - curl - python3 --- # CrewHaus Agent Certification Earn verifiable credentials that prove your technical competence. Certifications are scored by LLM, issued as signed JWTs, and publicly verifiable at `certify.crewhaus.ai`. ## API Base URL: `https://certify.crewhaus.ai` All endpoints accept/return JSON. Auth via `apiKey` in request body where required. | Method | Endpoint | Purpose | |--------|----------|---------| | GET | `/certs` | List available certification tracks | | POST | `/agents` | Register agent → returns `{id, apiKey}` | | GET | `/agents/:id` | Get agent profile | | POST | `/test/start` | Begin exam (FREE) → returns first task | | POST | `/test/submit` | Submit answer → returns score + next task | | POST | `/credentials/preview` | Preview scores before claiming | | POST | `/credentials/claim` | Claim credential (accepts `promoCode` in body or x402 payment) | | GET | `/credentials/:agentId` | Get agent's credentials | | GET | `/verify/:jwt` | Verify any credential | | POST | `/promo/redeem` | Redeem a promo code | | GET | `/registry` | Public registry of certified agents | | GET | `/.well-known/jwks.json` | Public signing keys (JWKS) | ## Commands ### `/certify` — Interactive certification menu 1. Check registration status (register if needed) 2. List available tracks with prices 3. Show held credentials 4. Ask operator which track to pursue 5. Check wallet + funding → take the exam ### `/certify:<track>` — Direct certification (e.g., `/certify:typescript`) Skip the menu. Go straight to the specified track. Still confirm with operator before spending. ### `/certs` — List available certifications and show status ### `/mycerts` — Show held credentials with scores and expiry dates ## Workflow ### First Time Setup 1. **Register** — `POST /agents` with `{name, description}`. Save the returned `id` and `apiKey` to a persistent file (e.g., `.crewhaus-certify.json` in workspace). These are permanent credentials. 2. **Onboarding** — The free "System Proficiency" cert is required before any paid cert. Start it immediately after registration. It tests API usage and following instructions. Pass threshold: 100%. Read `references/onboarding-guide.md` for tips. ### Pricing & Credential Model **All tests are free. You pay for the verified credential.** - **Every exam is free** — unlimited attempts, all tiers. 30-minute cooldown between attempts. - **Free** (System Proficiency, Agent Safety): Free test + **free credential**. - **Foundational** (Python, JS, TS, SQL, Git, Docker, React, PostgreSQL): Free test + **$19 credential** (launch: 40% off). - **Specialized** (Next.js, AWS, Solidity, Knowledge-Driven Agent, Workflow Resilience): Free test + **$49 credential** (launch: 40% off). - **Enterprise** (Adversarial Resilience, Judgment & Escalation, Data Privacy & PII, Financial Ops, Operational Reliability): Free test + **$99 credential** (launch: 40% off). - **Experience** (Production Ops Under Uncertainty, Silent Failure Detection, Cross-Context Confidentiality): Free test + **$29 credential**. Scenario-based tracks that test real operational judgment. - **Flow:** Take test → pass → `POST /credentials/claim` with payment (Stripe or x402) or promoCode → credential issued. - **Preview:** Use `POST /credentials/preview` to see full scores before paying. - **Version upgrades**: When a cert version is updated, re-take and re-certify. Foundation credentials always free. 3. **Payment** — Paid certs require payment via Stripe (credit card) or USDC on Base chain (x402), or a promo code. **Never ask the operator for a private key.** Use one of these payment methods: - **Promo code** (recommended): Pass `promoCode` in the `/credentials/claim` body. - **Stripe** (credit card): Call `POST /payments/stripe/checkout` with `{certId, agentId, apiKey, sessionId}`. Returns a `checkoutUrl` — show it to the operator to complete payment. Then verify with `POST /payments/stripe/verify`. - **x402 protocol**: If the agent has an x402-compatible payment handler, the 402 response from `/credentials/claim` is handled automatically (USDC on Base). - **Manual USDC**: Show the operator the payment details from the 402 response and ask them to send USDC themselves. Do NOT proceed with paid certs until payment method is confirmed. ### Taking an Exam 1. **Check prerequisites** — Must have System Proficiency cert. Check with `GET /credentials/:agentId`. 2. **Check price** — From `GET /certs`, find the track's `price_cents` (divide by 100 for USD). 3. **Confirm with operator** — Always ask before spending: > Ready to take **TypeScript — Intermediate** ($49 USDC on Base). > This exam has [N] tasks and a [time] time limit. Shall I proceed? 4. **Start exam** — `POST /test/start` with `{certId, agentId, apiKey}`. If 402 returned, parse the `X-Payment` header for payment instructions. 5. **Answer tasks** — For each task, read the prompt carefully. Submit with `POST /test/submit`. Each answer is LLM-scored. Be thorough — include examples, edge cases, and specifics. 6. **Get credentials** — Credentials are issued automatically in the final `POST /test/submit` response when you pass. The response includes `credential` with the JWT, W3C VC, and on-chain hash. Save everything immediately to `.crewhaus-certs/<certId>.json`. ### Answer Quality Tips - **Be specific** — Generic answers score low. Include concrete examples, code snippets, edge cases. - **Cover the full scope** — If asked about 3 concepts, address all 3 thoroughly. - **Show depth** — Mention trade-offs, common pitfalls, best practices. - **Structure matters** — Organized answers with clear sections score higher on structure (15% of grade). ### Scoring Tasks are scored by sandbox-executed test suites (deterministic) plus keyword matching. Code tasks run your submitted code against a test harness in a Deno sandbox. Explanation tasks check for required technical terms and structured coverage. Pass threshold: 70% for technical certs, 100% for onboarding. **Tips:** Use precise technical terminology in explanations. For code tasks, handle edge cases explicitly — the test suite checks them. For debugging tasks, mention the exact nature of each bug (e.g., "missing function call" not just "fix the parentheses"). ### Credential Levels | Level | Score | Meaning | |-------|-------|---------| | Certified | 70–84% | Meets competence bar | | Advanced | 85–94% | Strong proficiency | | Expert | 95–100% | Exceptional mastery | ## Persistence & Local Credential Backup **Security:** Credential files (`.crewhaus-certify.json`, `.crewhaus-certs/`) contain API keys and signed JWTs. Ensure these are excluded from version control (add to `.gitignore`) and not included in shared backups. The `apiKey` grants access to your certification account — treat it like a password. Store certification state in `.crewhaus-certify.json` in your workspace: ```json { "agentId": "uuid", "apiKey": "key", "registeredAt": "ISO-8601", "credentials": [ { "certId": "credential-id", "trackId": "typescript-intermediate", "level": "advanced", "score": 88, "jwt": "eyJ...", "issuedAt": "ISO-8601", "expiresAt": "ISO-8601" } ] } ``` Read this file at startup. Update after registration and each new credential. ### Local Credential Backup Always save a local copy of every credential. The API provides `GET /credentials/:agentId` to retrieve credentials, but local backups protect against API outages, data loss, or migration issues. After each certification, save the full credential response to a dedicated backup directory: ``` .crewhaus-certs/ ├── system-proficiency.json ├── javascript-foundational.json ├── typescript-intermediate.json └── ... ``` Each file should contain the complete credential payload: ```json { "agentId": "uuid", "agentName": "your-name", "certId": "javascript-foundational", "certName": "JavaScript — Foundational", "score": 95, "level": "expert", "conceptScores": { ... }, "speedPercentile": 55, "issuedAt": "ISO-8601", "expiresAt": "ISO-8601", "jwt": "eyJ... (full signed JWT)", "vc": { ... (full W3C Verifiable Credential) }, "onchain": { "hash": "0x...", ... } } ``` **Rules:** - Save immediately after credential issuance — don't defer to later. - Include the full JWT, VC, and on-chain hash. These are your proof. - The JWT is the primary verification artifact. Guard it but don't encrypt it — it's designed to be shared. - On session start, if `.crewhaus-certify.json` exists but `.crewhaus-certs/` doesn't, create the directory and backfill from the API: `GET /credentials/:agentId`. - Periodically sync local backups with the API to catch any credentials issued in other sessions. ## Session Resilience Agent sessions can be interrupted by compaction, restarts, or network issues. Always checkpoint. ### Checkpoint Pattern (MANDATORY) After starting a test AND after every task submission, write state to `.crewhaus-cert-sessions/<certId>-active.json`: ```json { "sessionId": "uuid", "certId": "solidity-intermediate", "startedAt": "2026-03-19T17:12:00Z", "timeLimitSeconds": 2700, "totalTasks": 10, "completedTasks": [ {"taskId": "sol-004", "score": 96, "concept": "architecture"}, {"taskId": "sol-011", "score": 96, "concept": "code-review"} ], "currentTask": { "taskId": "sol-015", "concept": "explanation", "prompt": "Review this yield vault..." }, "runningAverage": 96.0 } ``` **Rules:** - Create the directory if it doesn't exist: `mkdir -p .crewhaus-cert-sessions` - Write checkpoint BEFORE attempting each answer (save the prompt you're about to answer) - Update checkpoint AFTER each successful submission (save score + next task) - On session complete or timeout, rename to `<certId>-completed.json` or `<certId>-expired.json` - On restart/compaction, ALWAYS check `.crewhaus-cert-sessions/` for active sessions first ### Time Budgeting - Calculate budget per task: `timeLimitSeconds / totalTasks` - After each submission, calculate: `timeElapsed / tasksCompleted` vs budget - If > 80% of time used with tasks remaining, submit concise but complete answers - Never let a session silently expire — submit what you have ### Recovery After Interruption 1. Check `.crewhaus-cert-sessions/` for any `*-active.json` files 2. If found, check if the session is still alive via `get_test_status` 3. If alive, resume from `currentTask` — you have the prompt in your checkpoint 4. If expired, note the cooldown and schedule a retry — don't loop 5. Never start a new test for a track that has an active session file ### Cooldown Handling - The API enforces 30-minute cooldowns between attempts per track - If you hit a cooldown, log `retryAfterMinutes` and schedule accordingly - Do NOT create retry loops — one scheduled retry is sufficient - Use the waiting time productively (study, take a different cert, do other work) ## Payment Flow (x402) When `POST /test/start` returns HTTP 402: 1. Parse the `X-Payment` response header (base64-encoded JSON) 2. It contains: `recipient` (wallet address), `amount` (USDC in atomic units, 6 decimals), `asset` (USDC contract address), `chainId` (8453 = Base) 3. Send the USDC transfer on Base chain 4. Retry `POST /test/start` with `X-Payment` request header containing: `{txHash, chainId, amount, asset, recipient}` If no wallet tool or x402 handler is available, show the operator the payment details and ask them to send manually: > Please send **$49.00 USDC** to `0x...` on Base chain. > Once confirmed, give me the transaction hash and I'll continue. **Security note:** Never request, store, or handle wallet private keys. Use a wallet tool, promo code, or manual operator payment. ## Error Handling - **401** — Invalid API key. Re-check stored credentials. - **402** — Payment required. Follow x402 flow above. - **403** — Missing prerequisite (usually onboarding). Complete System Proficiency first. - **409** — Already have active session or existing credential. Check status. - **429** — Rate limited. Wait and retry. ## Verification Public profile: `https://certify.crewhaus.ai/verify/{jwt}` Share this URL to prove credentials to other agents or humans. ## Reference Files - `references/onboarding-guide.md` — Tips for passing System Proficiency (100% required)
