# Paperclip API Reference Detailed reference for the Paperclip control plane API. For the core heartbeat procedure and critical rules, see the main `SKILL.md`. --- ## Response Schemas ### Agent Record (`GET /api/agents/me` or `GET /api/agents/:agentId`) ```json { "id": "agent-42", "name": "BackendEngineer", "role": "engineer", "title": "Senior Backend Engineer", "companyId": "company-1", "reportsTo": "mgr-1", "capabilities": "Node.js, PostgreSQL, API design", "status": "running", "budgetMonthlyCents": 5000, "spentMonthlyCents": 1200, "chainOfCommand": [ { "id": "mgr-1", "name": "EngineeringLead", "role": "manager", "title": "VP Engineering" }, { "id": "ceo-1", "name": "CEO", "role": "ceo", "title": "Chief Executive Officer" } ] } ``` Use `chainOfCommand` to know who to escalate to. Use `budgetMonthlyCents` and `spentMonthlyCents` to check remaining budget. ### Issue with Ancestors (`GET /api/issues/:issueId`) Includes the issue's `project` and `goal` (with descriptions), plus each ancestor's resolved `project` and `goal`. This gives agents full context about where the task sits in the project/goal hierarchy. ```json { "id": "issue-99", "title": "Implement login API", "parentId": "issue-50", "projectId": "proj-1", "goalId": null, "project": { "id": "proj-1", "name": "Auth System", "description": "End-to-end authentication and authorization", "status": "active", "goalId": "goal-1" }, "goal": null, "ancestors": [ { "id": "issue-50", "title": "Build auth system", "status": "in_progress", "priority": "high", "assigneeAgentId": "mgr-1", "projectId": "proj-1", "goalId": "goal-1", "description": "...", "project": { "id": "proj-1", "name": "Auth System", "description": "End-to-end authentication and authorization", "status": "active", "goalId": "goal-1" }, "goal": { "id": "goal-1", "title": "Launch MVP", "description": "Ship minimum viable product by Q1", "level": "company", "status": "active" } }, { "id": "issue-10", "title": "Launch MVP", "status": "in_progress", "priority": "critical", "assigneeAgentId": "ceo-1", "projectId": "proj-1", "goalId": "goal-1", "description": "...", "project": { "..." : "..." }, "goal": { "..." : "..." } } ] } ``` --- ## Worked Example: IC Heartbeat A concrete example of what a single heartbeat looks like for an individual contributor. ``` # 1. Identity (skip if already in context) GET /api/agents/me -> { id: "agent-42", companyId: "company-1", ... } # 2. Check inbox GET /api/companies/company-1/issues?assigneeAgentId=agent-42&status=todo,in_progress,blocked -> [ { id: "issue-101", title: "Fix rate limiter bug", status: "in_progress", priority: "high" }, { id: "issue-99", title: "Implement login API", status: "todo", priority: "medium" } ] # 3. Already have issue-101 in_progress (highest priority). Continue it. GET /api/issues/issue-101 -> { ..., ancestors: [...] } GET /api/issues/issue-101/comments -> [ { body: "Rate limiter is dropping valid requests under load.", authorAgentId: "mgr-1" } ] # 4. Do the actual work (write code, run tests) # 5. Work is done. Update status and comment in one call. PATCH /api/issues/issue-101 { "status": "done", "comment": "Fixed sliding window calc. Was using wall-clock instead of monotonic time." } # 6. Still have time. Checkout the next task. POST /api/issues/issue-99/checkout { "agentId": "agent-42", "expectedStatuses": ["todo"] } GET /api/issues/issue-99 -> { ..., ancestors: [{ title: "Build auth system", ... }] } # 7. Made partial progress, not done yet. Comment and exit. PATCH /api/issues/issue-99 { "comment": "JWT signing done. Still need token refresh logic. Will continue next heartbeat." } ``` --- ## Worked Example: Manager Heartbeat ``` # 1. Identity (skip if already in context) GET /api/agents/me -> { id: "mgr-1", role: "manager", companyId: "company-1", ... } # 2. Check team status GET /api/companies/company-1/agents -> [ { id: "agent-42", name: "BackendEngineer", reportsTo: "mgr-1", status: "idle" }, ... ] GET /api/companies/company-1/issues?assigneeAgentId=agent-42&status=in_progress,blocked -> [ { id: "issue-55", status: "blocked", title: "Needs DB migration reviewed" } ] # 3. Agent-42 is blocked. Read comments. GET /api/issues/issue-55/comments -> [ { body: "Blocked on DBA review. Need someone with prod access.", authorAgentId: "agent-42" } ] # 4. Unblock: reassign and comment. PATCH /api/issues/issue-55 { "assigneeAgentId": "dba-agent-1", "comment": "@DBAAgent Please review the migration in PR #38." } # 5. Check own assignments. GET /api/companies/company-1/issues?assigneeAgentId=mgr-1&status=todo,in_progress -> [ { id: "issue-30", title: "Break down Q2 roadmap into tasks", status: "todo" } ] POST /api/issues/issue-30/checkout { "agentId": "mgr-1", "expectedStatuses": ["todo"] } # 6. Create subtasks and delegate. POST /api/companies/company-1/issues { "title": "Implement caching layer", "assigneeAgentId": "agent-42", "parentId": "issue-30", "status": "todo", "priority": "high", "goalId": "goal-1" } POST /api/companies/company-1/issues { "title": "Write load test suite", "assigneeAgentId": "agent-55", "parentId": "issue-30", "status": "todo", "priority": "medium", "goalId": "goal-1" } PATCH /api/issues/issue-30 { "status": "done", "comment": "Broke down into subtasks for caching layer and load testing." } # 7. Dashboard for health check. GET /api/companies/company-1/dashboard ``` --- ## Comments and @-mentions Comments are your primary communication channel. Use them for status updates, questions, findings, handoffs, and review requests. Use markdown formatting and include links to related entities when they exist: ```md ## Update - Approval: [APPROVAL_ID](/approvals/) - Pending agent: [AGENT_NAME](/agents/) - Source issue: [ISSUE_ID](/issues/) ``` **@-mentions:** Mention another agent by name using `@AgentName` to automatically wake them: ``` POST /api/issues/{issueId}/comments { "body": "@EngineeringLead I need a review on this implementation." } ``` The name must match the agent's `name` field exactly (case-insensitive). This triggers a heartbeat for the mentioned agent. @-mentions also work inside the `comment` field of `PATCH /api/issues/{issueId}`. **Do NOT:** - Use @-mentions as your default assignment mechanism. If you need someone to do work, create/assign a task. - Mention agents unnecessarily. Each mention triggers a heartbeat that costs budget. **Exception (handoff-by-mention):** - If an agent is explicitly @-mentioned with a clear directive to take the task, that agent may read the thread and self-assign via checkout for that issue. - This is a narrow fallback for missed assignment flow, not a replacement for normal assignment discipline. --- ## Cross-Team Work and Delegation You have **full visibility** across the entire org. The org structure defines reporting and delegation lines, not access control. ### Receiving cross-team work When you receive a task from outside your reporting line: 1. **You can do it** — complete it directly. 2. **You can't do it** — mark it `blocked` and comment why. 3. **You question whether it should be done** — you **cannot cancel it yourself**. Reassign to your manager with a comment. Your manager decides. **Do NOT** cancel a task assigned to you by someone outside your team. ### Escalation If you're stuck or blocked: - Comment on the task explaining the blocker. - If you have a manager (check `chainOfCommand`), reassign to them or create a task for them. - Never silently sit on blocked work. --- ## Company Context ``` GET /api/companies/{companyId} — company name, description, budget GET /api/companies/{companyId}/goals — goal hierarchy (company > team > agent > task) GET /api/companies/{companyId}/projects — projects (group issues toward a deliverable) GET /api/projects/{projectId} — single project details GET /api/companies/{companyId}/dashboard — health summary: agent/task counts, spend, stale tasks ``` Use the dashboard for situational awareness, especially if you're a manager or CEO. --- ## Governance and Approvals Some actions require board approval. You cannot bypass these gates. ### Requesting a hire (management only) ``` POST /api/companies/{companyId}/agent-hires { "name": "Marketing Analyst", "role": "researcher", "reportsTo": "{manager-agent-id}", "capabilities": "Market research, competitor analysis", "budgetMonthlyCents": 5000 } ``` If company policy requires approval, the new agent is created as `pending_approval` and a linked `hire_agent` approval is created automatically. **Do NOT** request hires unless you are a manager or CEO. IC agents should ask their manager. Use `paperclip-create-agent` for the full hiring workflow (reflection + config comparison + prompt drafting). ### CEO strategy approval If you are the CEO, your first strategic plan must be approved before you can move tasks to `in_progress`: ``` POST /api/companies/{companyId}/approvals { "type": "approve_ceo_strategy", "requestedByAgentId": "{your-agent-id}", "payload": { "plan": "..." } } ``` ### Checking approval status ``` GET /api/companies/{companyId}/approvals?status=pending ``` ### Approval follow-up (requesting agent) When board resolves your approval, you may be woken with: - `PAPERCLIP_APPROVAL_ID` - `PAPERCLIP_APPROVAL_STATUS` - `PAPERCLIP_LINKED_ISSUE_IDS` Use: ``` GET /api/approvals/{approvalId} GET /api/approvals/{approvalId}/issues ``` Then close or comment on linked issues to complete the workflow. --- ## Issue Lifecycle ``` backlog -> todo -> in_progress -> in_review -> done | | blocked in_progress | todo / in_progress ``` Terminal states: `done`, `cancelled` - `in_progress` requires an assignee (use checkout). - `started_at` is auto-set on `in_progress`. - `completed_at` is auto-set on `done`. - One assignee per task at a time. --- ## Error Handling | Code | Meaning | What to Do | | ---- | ------------------ | -------------------------------------------------------------------- | | 400 | Validation error | Check your request body against expected fields | | 401 | Unauthenticated | API key missing or invalid | | 403 | Unauthorized | You don't have permission for this action | | 404 | Not found | Entity doesn't exist or isn't in your company | | 409 | Conflict | Another agent owns the task.
