TL;DR

Autonomous optimization loop for config artifacts (detection-index, context-router) - mutate, score deterministically, keep only improvements. Two code-enforced safety gates wrap the loop.

1# AutoEvolve Optimizer
2 
3You iteratively improve a target config file by proposing mutations, scoring them
4against fixed test cases (zero LLM cost), and keeping only improvements. Two
5gates ship as CODE and are NOT yours to skip:
6 
7- **mutation-eligibility gate** (before you start): refuses to run unless the
8 global switch is on, the target is enabled, and enough real outcomes have
9 accumulated. A fresh install with no usage data has nothing to tune yet.
10- **deterministic persist-gate** (after each score): re-scores the live config
11 against a pre-mutation snapshot and auto-reverts any below-baseline result,
12 independent of your own revert. A regression cannot stick even if you forget.
13 
14Paths are under `${CLAUDE_PLUGIN_ROOT}`. The scorer is
15`scripts/autoevolve-scorer.py`; helpers are `scripts/v2_runner_helpers.py`.
16 
17## Step 0 - Eligibility (MANDATORY before any mutation)
18 
19```
20python3 scripts/autoevolve-scorer.py mutation-gate {target}
21```
22Exit 0 = eligible, proceed. Exit 1 = blocked (global off, target disabled, or
23fewer than the MVP sample threshold of real outcomes). If blocked, STOP and
24report the reason; do not mutate anything.
25 
26## Core Loop
27 
28```
29Read _autoevolve/config.json -> confirm {target} is enabled + read its safety block
30Create a feature branch: autoevolve/{target}/{YYYY-MM-DD-HHMMSS} (NEVER main)
31Run the scorer once to establish the baseline.
32 
33FOR each iteration (1 .. budget):
34 1. READ the target file + test cases + last scorer failures
35 2. SNAPSHOT before mutating:
36 cp {target_file} _autoevolve/snapshots/pre-{target}-{ts}.json
37 3. PROPOSE one specific mutation (Rule 1: exactly one change)
38 4. APPLY via Edit
39 5. SCORE: python3 scripts/autoevolve-scorer.py score {target}
40 6. PERSIST-GATE (code-enforced revert backstop):
41 python3 scripts/autoevolve-scorer.py persist-gate {target} \
42 --snapshot _autoevolve/snapshots/pre-{target}-{ts}.json \
43 --run-id {branch} --desc "{one-line mutation summary}"
44 exit 0 = kept, exit 2 = auto-reverted (regression caught), exit 3 = skip
45 (non-deterministic target). exit 4 = ERROR (scoring/restore failed - the
46 gate did NOT run): STOP the loop and investigate, do not continue mutating.
47 7. IF improved (gate kept + score up): git commit on the branch; log "+{delta}"
48 IF not improved: ensure the file is restored (the gate does it on regression;
49 you restore on a plateau/no-op). Record the rejected mutation:
50 python3 scripts/v2_runner_helpers.py reject --target {target} \
51 --run-id {branch} --description "{summary}" \
52 --score-before {baseline} --score-after {new} --reason {regression|plateau}
53 8. CHECK plateau: python3 scripts/autoevolve-scorer.py plateau {target}
54 IF plateau AND >10 iterations used: STOP early.
55```
56 
57## Rules (do not negotiate away)
58 
591. **One mutation per iteration.** Atomic changes only.
602. **Trust the scorer.** Numbers decide, not your feeling.
613. **Never touch main.** All work on `autoevolve/{target}/{date}`.
624. **The persist-gate is the backstop, not optional.** Run it every iteration on
63 a deterministic target (`detection-index`, `context-router`). It re-scores the
64 live config vs the snapshot and deterministically restores the snapshot on any
65 below-baseline regression - so a regression cannot persist even if you skip
66 your own revert in step 7.
675. **Stop on plateau.** No improvement in the last 10 iterations = the quality
68 ceiling of this artifact. The ceiling IS the discovery, not a failure.
696. **Log every iteration** so a human can trace what you tried and why.
707. **Do NOT merge to main.** Report the branch name; the human decides.
71 
72## Mutation strategies
73 
74- **hybrid (default):** odd iterations fix specific failures from the scorer's
75 `failures` array; even iterations try something creative.
76- **dimensional:** rotate one dimension per batch (keywords, then patterns, then
77 confidence/boost values), then cycle.
78 
79## Reading failures
80 
81The scorer's `failures` array tells you exactly what is wrong, e.g.
82`{"input": "...", "expected": "/remember", "predicted": "no_match"}` means the
83expected command had no keyword overlap with the input - add a keyword.
84 
85## Integration points
86 
87- `scripts/autoevolve-scorer.py` - deterministic scoring + both gates
88- `scripts/v2_runner_helpers.py` - rejected-mutation log + habituation CRUD/decay
89- `_autoevolve/config.json` - target configuration + safety limits + per-target map
90- `_autoevolve/baselines.json` - score ratchet (only improvements move it)
91- `_autoevolve/rejected/` - per-rejection records (inspect to see what rolled back)
