skillberry-ai/cap-evolve

Skill Claude CodeCodex

Answers a short arithmetic question with just the number. Use when the user asks to compute a sum, difference, or product and wants only the result back.

skillberry-ai/cap-evolve

Plugin Claude Code

Optimize AI-agent capabilities (skills, tools/MCP, prompts, system prompts) against your eval, honestly. Skills-native and host-agnostic, with honest train/val/test discipline (sealed test, val-only gate) enforced by core-owned hooks. Exposes every phase/algorithm/capability/optimizer/orchestrate skill as a…

skillberry-ai/cap-evolve

Agent

Read-only failure analyst for the cap-evolve diagnose phase. Use to turn a candidate's failing val rollouts + traces into a structured reflective dataset (per-task failure signatures, clusters, and one actionable hypothesis per cluster) WITHOUT editing any files. Safe to fan out in parallel — many diagnosers can run…

skillberry-ai/cap-evolve

Agent

Writing edit-proposer for the cap-evolve optimizer step. Use to apply ONE targeted edit to a candidate working copy, given the reflective dataset from the diagnoser. Has write tools and uses a strong model. Edits only the candidate workdir handed to it — never the sealed test split, test rollouts, or gold files (the…

skillberry-ai/cap-evolve

Hook

Runs before the agent uses a tool for Edit, Write, MultiEdit and NotebookEdit tool calls, executing deny_sealed_edits.py via python3. From skillberry-ai/cap-evolve.

skillberry-ai/cap-evolve

Hook

Runs when the agent finishes a response, executing require_green_check.py via python3. From skillberry-ai/cap-evolve.

skillberry-ai/cap-evolve

Hook

Runs when a subagent finishes, executing require_green_check.py via python3. From skillberry-ai/cap-evolve.

skillberry-ai/cap-evolve

Hook

Runs when a session starts, executing inject_router.py via python3. From skillberry-ai/cap-evolve.

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Free-form optimization algorithm for agent orchestration mode: the conversational agent owns the whole search — proposing capability edits itself, screening them cheaply, gating each on full val, and sealing test once. Use when orchestrationmode is agent and algorithmskill is agent-optimize. For a deterministic loop…

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Deprecated agent-mode algorithm (evo-graph port): a weakness-graph search that dispatched one solver agent per failure cluster and reverted a whole round on regression. Do not start new runs with it — its per-weakness fan-out is already agent-optimize's sibling fan-out, done behind the honest val significance gate…

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Runs the GEPA optimization loop (arXiv:2507.19457) — sample-efficient reflective Pareto search. A cheap train-minibatch pre-gate decides whether a proposal is worth an expensive val evaluation, and parents are sampled from a per-instance frontier so specialists survive instead of being averaged away. Use when rollouts…

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Runs a global hill-climb optimization loop where the parent is always the current best candidate and the val significance gate decides acceptance. Use as the algorithm for most runs — the first run on a new project, binary pass/fail scorers, and small task sets. Pick how each iteration's reflection is focused with…

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Runs the SkillOpt single-lineage optimization loop, which organizes a hill-climb into epochs over mini-batches of train tasks under a textual learning rate — an integer edit budget that decays on a constant|linear|cosine schedule — and ends each epoch with one extra gated consolidation step. Parent is always the…

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Optimize the tool surface of an EXTERNAL MCP server — one the agent talks to but does not implement. Use when an agent wired to an MCP server mis-selects tools, fills arguments wrong, or is offered a noisy 40-tool set it mostly ignores. Covers MCP tool descriptions, per-parameter documentation, in-description…

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Optimize an Agent Skill package itself — its SKILL.md (frontmatter + body), its references, and its bundled scripts. Use when the capability under optimization IS a skill, you want the downstream agent to trigger it correctly and follow it without wasted steps, or you want a step the agent keeps skipping turned into…

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Optimize an agent's system prompt, developer message, or policy text — the instructions that shape its behavior. Use when the artifact to improve is a prompt or policy file rather than tools or a skill package: the agent lacks a rule, misses the required output format, or applies the wrong decision criterion. Covers…

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Optimize an agent's OWN tool surface (tools it implements, not an external MCP server). Use when the agent mis-selects tools, fills arguments wrong, calls the same tool N times in a row, or has a confusing, redundant, or oversized toolset. Covers tool names and descriptions, parameter docs, tool schemas, handler code…

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Drives any shell-invokable coding agent (Claude Code, Codex, Gemini CLI, opencode, Cursor, Factory Droid, GitHub Copilot CLI, Kimi, Pi, Antigravity, OpenClaw, IBM Bob, or a fully custom command) as the edit proposer in a cap-evolve run, resolving the named optimizer from optimizers/registry.yaml. Use this as the…

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Drive the entire cap-evolve pipeline end to end, autonomously. Use when the user wants the whole optimization run with minimal hand-holding. Sequences intake → implement-and-check → baseline → the chosen algorithm loop → finalize → report, enforces the cap-evolve-check hard gate before spending budget, decides when to…

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Front door for cap-evolve: routes an optimization request to the right pipeline phase. Use when someone wants an agent, skill, system prompt, tool surface, or MCP toolset to score higher on an eval, benchmark, or task suite — "optimize my skill", "raise the pass rate on these tasks", "my agent keeps failing these…

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Establish the starting point. Use after implement-and-check and before any algorithm. Creates the run directory, freezes the seeded train/val/test split (written once), scores the unmodified seed capability on val, and records it as the candidate every algorithm must beat. Reports the remaining headroom so a saturated…

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Extract the learning signal from execution traces — the textual analogue of a gradient. Use between evaluation and proposing edits. Reads a candidate's rollouts and traces, separates good signals to keep from bad signals to fix, builds a reflective dataset (per failing task — Inputs, Generated Outputs, Feedback) and…

skillberry-ai/cap-evolve

Skill Claude CodeCodex

Score a candidate on a split with honest, variance-aware evaluation. Use whenever you need a number for a candidate (the algorithm calls it internally; you can also call it directly to inspect). Runs the target via the adapter for each task, scores each rollout, aggregates mean + standard error, and reports pass^k…
