recursive-execution

recursive-execution is a skill for Claude Code, Codex from Jartan-LLC/grimoire. It costs 22 tokens per session (559 once invoked), scanned A, original, MIT.

A set of rules for coordinating recursive development agents in ordered waves.

In plain words
What is it for?
It is for enforcing scope separation, interface matching, sequential wave barriers, foreground parallel execution, retries, and escalation when an agent fails.
Why use it?
It defines how agents share work, wait for dependent work, handle failures, and delegate fixes without losing changes.

Token cost

What 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.

Security

Grade A, and why

recursive-execution 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 4d 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.

The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

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.

recursive-execution is a skill published in the GitHub repository Jartan-LLC/grimoire (2 stars, last pushed 17d ago), licensed MIT. It adds 22 tokens to every session and 559 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
