Recursive Execution

Agent Constraints

These apply to ALL agents in the recursive tree:

• No worktree isolation. Never use isolation: "worktree". Worktree agents work in a copy -- files get discarded on cleanup.
• No background agents. Never use run_in_background: true. Background dispatch triggers worktree isolation. Use foreground Agent calls -- send parallel agents in a single message for concurrency.
• Fix delegation. Simple fixes (unused import, missing return) directly. Logic fixes (bugs, structural merges) via a recursive-implementer scoped to affected files with findings in the prompt.
• Failure escalation. When a child agent fails: parent retries (max 2), restructures (split differently), or escalates to its own parent. Handle failures at the lowest level that has enough context to fix them.

Wave Execution

Waves execute sequentially. Within each wave, agents run in parallel.

Wave barrier: all agents must complete before running tests or starting the next wave. Send all wave agents as foreground calls in a single message when possible. Sequential dispatch is acceptable when needed.

Typical structure:

• Wave 0: Contracts + setup (uses recursive-implementer)
• Wave 1+: Implementation modules (parallel recursive-implementer agents)
• Final wave: Integration tests + documentation

Adapting mid-flight: the orchestrator may add missing deps, adjust types, reorder/merge modules, fix structural issues between waves, and adjust scope boundaries.

Review-Fix Evaluation

After each wave, spawn a recursive-reviewer scoped to the wave's output:

Post-Wave 0: review contracts for richness -- are interfaces complete enough for downstream modules? Fix gaps directly.

Post-implementation waves: review for bugs, structural artifacts, cross-module consistency. Fix Critical findings via implementer agents (max 2 rounds). Note Important findings.

Post-final wave: full codebase review. Fix Critical. Verify README.md and CHANGELOG.md exist -- create via implementer if missing.

Report: total tests, files, max nesting depth, findings summary (found/fixed).

Language Awareness

The wave plan's Language & Conventions section determines:

• Test command (pytest, npx vitest run, cargo test)
• Types/contracts file path
• Setup command (npm install, uv sync)

Include Language & Conventions in every subagent prompt.
