## What it does

This skill covers the grade-then-fix loop for a Claude Managed Agent. `outcome_builder.py` turns the agent's build sheet into a `user.define_outcome` payload. A rubric is mandatory, and `max_iterations` is clamped between 1 and 20 — the loop is never open-ended.

\`verdict_reader.py` then reads the grader result and names the next move: SHIP on `satisfied`, SHARPEN and re-run on `needs_revision`, ESCALATE on `max_iterations_reached` or `failed`, RESUME on `interrupted`. With one iteration or less left, it tells you to make the single highest-value fix or escalate right away. Each pass has to flip at least one rubric line from fail to pass, or the run stops at the cap.

After a version passes, `eval_scaffold.py` builds held-back cases and a parallel run plan, capped at the 25-thread CMA ceiling. Those cases stay unseen during iteration — grading generalization on cases the agent already tuned against tells you nothing. This is a separate phase from the first launch and from putting the agent on a schedule.

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add alirezarezvani/claude-skills
```
In the agent chat (not a shell):
```text
/plugin install agent-launcher-skills@claude-code-skills
```
This installs the whole agent-launcher-skills plugin with all its skills

2. **Skills CLI (Vercel)**
```bash
npx skills add alirezarezvani/claude-skills --skill grade-iterate -a claude-code
```

3. **Manually: put the files in place**
- File: `~/.claude/skills/grade-iterate/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/grade-iterate/

### Codex

**Manually: put the files in place**
- File: `.agents/skills/grade-iterate/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/grade-iterate/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install alirezarezvani/claude-skills grade-iterate
```

2. **Manually: put the files in place**
- File: `.github/skills/grade-iterate/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/alirezarezvani/claude-skills --path agent-launcher/skills/grade-iterate
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/grade-iterate/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/alirezarezvani/claude-skills/tree/HEAD/agent-launcher/skills/grade-iterate/SKILL.md

## When to use it
- define a rubric and iteration cap for a CMA agent
- read a grader verdict and pick the next move
- tell a prompt fix from a tool fix after a failure
- run held-back cases in parallel once a version passes
- record the verdict on the goal before scheduling

## Example prompts
- Grade my agent against the rubric and tell me what to fix
- Iterate until it passes the rubric
- Scaffold held-back cases and a parallel run plan for my agent

description: Phase 3 of building a Claude Managed Agent — the bounded grade→iterate loop. Define a CMA outcome (a required markdown rubric graded by an isolated grader), read each verdict, decide the next move (sharpen / re-run / promote to schedule), and once a version passes, run held-back eval cases in parallel. Use when the user says "grade my agent", "make it pass the rubric", "iterate until it's good", "is it good enough", or when the orchestrator routes phase=grade-iterate. outcome_builder.py builds the user.define_outcome payload (rubric required, max_iterations clamped 1..20 — never unbounded); verdict_reader.py reads the grader result and recommends the next move; eval_scaffold.py generates held-back cases + a parallel run plan (capped at the 25-thread CMA ceiling). Distinct from stage-launch (first launch) and run-without-you (scheduling).

# Phase 3 — Grade → Iterate (the bounded loop)

This is the plugin's **loop**: CMA's `outcome` primitive self-grades the agent's
work in an isolated context and feeds failing verdicts back for the next attempt.
It is **always bounded** by `max_iterations` (1..20) — never "improve forever".

See [`../../references/loops-and-workflows.md`](../../references/loops-and-workflows.md)
and the outcome section of
[`../../references/cma-primitives.md`](../../references/cma-primitives.md).

## Workflow

1. **Define the outcome.**
   ```bash
   python3 scripts/outcome_builder.py \
     --sheet ./my-agent/build-sheet.json --max-iterations 5 \
     --out ./my-agent/payloads/outcome.json
   ```
   The **rubric is required**; `max_iterations` is clamped to 1..20. Send the
   payload as a `user.define_outcome` event (append to the running session).
2. **Read every verdict first.**
   ```bash
   python3 scripts/verdict_reader.py --result ./my-agent/last-verdict.json
   ```
   Tables the rubric outcome and recommends: **SHIP** (`satisfied`), **SHARPEN**
   then re-run (`needs_revision`), **ESCALATE** (`max_iterations_reached` /
   `failed`), **RESUME** (`interrupted`). With ≤1 iteration left it flips to
   "make the single highest-value fix or escalate now".
3. **Loop invariant.** Each iteration must move ≥1 rubric line fail→pass, or the
   run halts at the cap and escalates. Don't burn the budget on cosmetic edits.
4. **Once a version passes, run held-back eval.**
   ```bash
   python3 scripts/eval_scaffold.py \
     --sheet ./my-agent/build-sheet.json --out ./my-agent/eval.json --concurrency 5
   ```
   Held-back cases (never seen during iteration) run in parallel, capped at the
   25-thread CMA ceiling, each graded against the same rubric.
