GEPA reflective prompt evolution optimizer for superred agent targets

superred-optimizer-gepa-agentic

An agent-target variant of GEPA reflective prompt evolution for the superred red-teaming framework.

This keeps GEPA's core reflective-mutation loop — one evolving textual candidate, refined between runs by a reflection LM call on the best-scoring rollout so far — but adds an agentic delivery policy on top: at initialize() it inspects the in-scope controllables, classifies which ones look like agent content surfaces (tool returns, retrieved context, memory records, web/document content — AgentDojo-style read__..., inspect-agent tool:<name>, skill aliases, and generic memory/RAG/web hints all count as weak signals), builds a deterministic per-run injection plan across whichever surfaces actually fire (capped per run), and falls back to the plain prompt channel only when no content surface is available. Reflection also gets richer scoped context than the base optimizer: which surfaces were selected and observed, preserved tool returns, static observables, and a bounded slice of the agent trace.

This is a separate package from superred-optimizer-gepa — the chatbot GEPA implementation there is intentionally left unchanged; see its ASSUMPTIONS.md for the base algorithm and this package's ASSUMPTIONS.md for the agentic delivery layer and what is deliberately deferred (full Pareto-frontier maintenance, full tool catalog register/replace).

Install

pip install superred-optimizer-gepa-agentic

Usage

from gepa_agentic_optimizer import GEPAAgenticOptimizer

optimizer = GEPAAgenticOptimizer(
    max_attempts=20,
    max_content_injections_per_run=3,
)

Wire it into a Controller against an agent target (e.g. agentdojo_target, inspect_agent_target) — see the framework's architecture overview for a full Controller.run() example.

Behaviour notes

• Surface naming is a weak signal, not a contract. Detection also uses PostCall metadata, value type, and runtime content shape, so it degrades gracefully against agent targets that don't follow the AgentDojo/inspect-agent naming conventions.
• GEPA-style strict-improvement acceptance: a reflected candidate only stays in the pool if it succeeded or scored strictly better than its parent, closer to the paper's acceptance test than the base gepa package's single-instance collapse (still not a full replay-based acceptance test, since superred has no fixed minibatch to replay).
• tool_catalog_rewrite_doc gives a minimal text-rewrite capability when a visible tool catalog identifies a content/read/search-like tool; full register/replace of tool definitions is a documented follow-up, not implemented, because it needs a stricter JSON contract than this optimizer currently assumes.
