Sub-agents — prometeo, forja, centinela
The three agents that execute the Inceptor loop.
Three Claude Code sub-agents under .claude/agents/ execute the Inceptor
development loop. The main Claude Code session is the orchestrator — it dispatches
agents via the Task tool and reads their output to drive the next step.
The three agents
prometeo — planner
Reads INTEGRATION-PLAN.md and decomposes a phase, milestone, or issue into an
ordered, dependency-aware execution plan.
- Does: read the plan, check GitHub issue state, build a dependency graph, produce a typed execution plan with risk ratings
- Does not: write code, run
npm/npx, or modify files - Invoked when: the orchestrator receives a phase/milestone/issue to work
forja — implementer
Implements a single issue: writes code, runs npx commands, makes atomic commits
on a feature branch.
- Does: create/modify files per acceptance criteria, run
npx shadcn add/npx astro add, commit with Conventional Commits + issue ref - Does not: validate work (centinela’s job), open PRs (orchestrator’s job)
- Invoked when: prometeo’s plan is approved for a specific issue
centinela — validator
Validates forja’s work and returns APPROVED or REJECTED with a routing token.
- Does: run
npm run build,npm run check,npm run test, forbidden-import scan, ethics checklist check - Returns:
APPROVED|REJECTED+ one ofRETRY_FORJA,NEEDS_HUMAN,BLOCKED_UPSTREAM - Invoked when: forja finishes a commit sequence
The loop
orchestrator
→ prometeo (plan) → you approve
→ forja (implement) → commits on branch
→ centinela (verify) → APPROVED / REJECTED
→ (on APPROVED) push branch, open PR, close issue
→ repeat for next issue
On REJECTED, the routing token drives what happens next:
| Token | Meaning | Next step |
|---|---|---|
RETRY_FORJA | Fixable code issue | Re-dispatch forja with centinela’s diff |
NEEDS_HUMAN | Ambiguous / outside spec | Escalate to human |
BLOCKED_UPSTREAM | Dependency unresolved | Stop; fix the upstream issue first |
