The mutation of the skill corpus\nis the exclusive job of a separate, human-invoked skill: [`/meta-apply`](../meta-apply/SKILL.md).\nThis split is structural, not advisory — it is why a missed instruction cannot let\nthis loop apply its own patch (the self-acquittal failure mode):\n\n- **No `Write`/`Edit` tool.** This skill cannot edit a SKILL.md / shared-reference /\n  any corpus file with the frictionless mutators. Its only outputs are the REPORT and\n  staged patch files, written under `.aris/meta/` (a scratch area, never the corpus).\n- **No apply step.** There is no in-skill \"apply the patch\" path (see Step 6). The\n  producer ends by *staging* approved patches for `/meta-apply`; a human must then\n  invoke `/meta-apply` to land them. That human action is the landing gate.\n- **`Bash` writes to the corpus are filtered, not impossible — be honest about the\n  layers.** What IS fully closed: the *accidental / in-flow* self-acquittal — this skill\n  has no `Write`/`Edit` and no apply step, so an honest run cannot slip into editing the\n  corpus. Defense-in-depth: install the\n  [`corpus_write_guard`](../../templates/claude-hooks/corpus_write_guard.json) PreToolUse\n  hook (like `meta_logging.json`), which DENIES the common Bash shell-writes (`>`, `tee`,\n  `sed -i`, `cp`/`mv`, `touch`, `open(...,'w')`) to corpus paths. **This is a blacklist,\n  NOT a complete sandbox** — a *deliberately* obscured Bash write (`git apply`, `patch`,\n  `$var`/absolute paths, language file APIs) is not all caught. **Full structural\n  prevention requires either removing this skill's `Bash` or an FS sandbox** — over-built\n  for a not-yet-load-bearing producer, so deferred to when the gate carries real\n  auto-modification volume (a brick-3 trigger). The intended backstop against a deliberate\n  write is **detection, not prevention** — a corpus change with no valid/current\n  `provenance` stamp (content-hash mismatch) *would be* catchable in a pre-push integrity\n  check — but that verifier is **NOT yet built** (`provenance.py` has `content_hash` but no\n  integrity-check subcommand, and no pre-push hook runs one). So today the deliberate-write\n  case is neither prevented nor actively detected; track the integrity verifier as a\n  follow-up before this producer goes load-bearing. Its legitimate Bash writes go only to\n  `.aris/meta/`.\n\nSee [`shared-references/acceptance-gate.md`](../shared-references/acceptance-gate.md):\na loop can DRIVE (propose, review) same-model, but the ACQUITTAL that lands a change\nmust be cross-model (Step 4 jury) **and** the landing must be a separate human-gated\nact (`/meta-apply`).\n\n## Context\n\nARIS is a **research harness** — a system of skills, bridges, workflows, and artifact contracts that wraps around LLMs to orchestrate research. This skill implements a prototype **outer loop** that observes how the harness is used and proposes improvements to the harness itself (not to the research artifacts it produces).\n\nInspired by Meta-Harness (Lee et al., 2026): the key insight is that harness design matters as much as model weights, and harness engineering can be partially automated by logging execution traces and using them to guide improvements.\n\n## What This Skill Optimizes (Harness Components)\n\n| Component | Example | Optimizable? |\n|-----------|---------|:---:|\n| SKILL.md prompts | Reviewer instructions, quality gates, step descriptions | Yes |\n| Default parameters | `difficulty: medium`, `MAX_ROUNDS: 4`, `threshold: 6/10` | Yes |\n| Convergence rules | When to stop the review loop, retry counts | Yes |\n| Workflow ordering | Skill chain sequence within a workflow | Yes |\n| Artifact schemas | What fields go in EXPERIMENT_LOG.md, idea-stage/IDEA_REPORT.md | Cautious |\n| MCP bridge config | Which reviewer model, routing rules | No (infra) |\n\n**Not optimized**: The research artifacts themselves (papers, code, experiments). That's what the regular workflows do.\n\n## Prerequisites\n\n1. **Logging must be active.** Copy `templates/claude-hooks/meta_logging.json` into your project's `.claude/settings.json` (or merge the hooks section).\n2. **Sufficient data.** At least 5 complete workflow runs logged in `.aris/meta/events.jsonl`. The skill will check and warn if insufficient.\n\n## Workflow\n\n### Step 0: Check Data Availability\n\n```bash\nEVENTS_FILE=\".aris/meta/events.jsonl\"\nif [ ! -f \"$EVENTS_FILE\" ]; then\n    echo \"ERROR: No event log found at $EVENTS_FILE\"\n    echo \"Enable logging first: copy templates/claude-hooks/meta_logging.json into .claude/settings.json\"\n    exit 1\nfi\n\nEVENT_COUNT=$(wc -l < \"$EVENTS_FILE\")\nSKILL_INVOCATIONS=$(grep -c '\"skill_invoke\"' \"$EVENTS_FILE\" || echo 0)\nSESSIONS=$(grep -c '\"session_start\"' \"$EVENTS_FILE\" || echo 0)\n\necho \"📊 Event log: $EVENT_COUNT events, $SKILL_INVOCATIONS skill invocations, $SESSIONS sessions\"\n\nif [ \"$SKILL_INVOCATIONS\" -lt 5 ]; then\n    echo \"⚠️  Insufficient data (<5 skill invocations). Continue using ARIS normally and re-run later.\"\n    exit 0\nfi\n\n# Bottleneck succession: what did the LAST cycle say was the limiting stage?\nBOTTLENECK_LOG=\".aris/meta/bottleneck_log.jsonl\"\nif [ -f \"$BOTTLENECK_LOG\" ]; then\n    echo \"🧭 Prior cycle's bottleneck: $(tail -1 \"$BOTTLENECK_LOG\")\"\nfi\n```\n\nIf a prior bottleneck entry exists, open the report (Step 5) by stating whether\nthat named bottleneck was **resolved** (and by which landed patches) and what it\nhas now **moved to** — bottleneck SUCCESSION, not just existence, is the signal\nthis ledger exists to carry.\n\n### Step 1: Analyze Usage Patterns\n\nRead `.aris/meta/events.jsonl` and compute:\n\n**Frequency analysis:**\n- Which skills are invoked most often?\n- Which slash commands do users type most?\n- What parameter overrides are most common? (These suggest bad defaults.)\n\n**Failure analysis:**\n- Which tools fail most often? In which skills?\n- What error patterns repeat? (OOM, import, compilation, timeout)\n- How many auto-debug retries per workflow run?\n\n**Convergence analysis (for auto-review-loop):**\n- Average rounds to reach threshold\n- Score trajectory shape (fast improvement? plateau? oscillation?)\n- Which review round catches the most critical issues?\n- Do users override difficulty mid-run?\n\n**Human intervention analysis:**\n- Where do users interrupt with manual prompts during workflows?\n- What manual corrections do users make most? (These indicate skill gaps.)\n\n**Model-delta analysis (harness diet):**\n- Has the session model (`session_start` events' `model` field) or the pinned\n  reviewer model changed since a skill's SKILL.md was last touched?\n  (`git log -1 --format=%cs -- skills/<skill>/SKILL.md` vs the model-bump date.)\n- A model bump is a **trigger to re-read, not evidence by itself**. For each\n  reasoning-scaffolding step or worked example in that SKILL.md, a deletion\n  proposal must cite TARGET-SPECIFIC evidence that the new model no longer\n  needs it: a capability-specific release note, or repeated observed behavior\n  in the event log (e.g. zero failures/interventions in the guarded step since\n  the bump). \"The model got newer\" alone never justifies a deletion.\n- **Never deletion candidates**, regardless of model: privilege boundaries,\n  acceptance/review gates, corpus- and provenance-integrity rules, output\n  contracts, and safety checks. The diet targets model-compensation scaffolding\n  only — a capability the new model has natively is pure overhead (context\n  weight, drift surface, reading cost). A harness that only ever grows is a\n  harness nobody is re-reading.\n\n**Trigger-rate analysis (optional, measured — not from the event log):**\n- The event log shows which skills were USED, not which were WANTED-but-omitted\n  — the omission failure mode (Claude Code passing over the right skill when the\n  installed list is long) is invisible to it. `tools/meta_opt/trigger_eval.py`\n  measures it directly: `claude -p` probes with paraphrased-intent queries run\n  from a neutral cwd (so the realistic long installed corpus is loaded), scored\n  as trigger / confusion(→which skill) / miss.\n- Run it when a specific skill is suspected of under- or mis-triggering, or as a\n  before/after check around a description edit:\n  `python3 tools/meta_opt/trigger_eval.py --eval-file tools/meta_opt/trigger_evals.sample.json --skills <name> --samples 2`\n- The **confusion matrix is the signal**, not just the rate: a query that keeps\n  landing on a sibling skill means the two descriptions overlap on that intent —\n  the fix is disambiguation, not \"make the description pushier\".\n- **Measure-only, evidence not verdict.** A low trigger rate is an INPUT to a\n  Step-2 proposal (which lands only via `/meta-apply`), never a self-applied\n  description rewrite. Trigger rate is model-dependent, so compare like with\n  like (record the probe model) and treat it as a proxy — it measures selection\n  under a query set, not the full long-list omission problem.\n\nPresent findings as a structured summary table.\n\n### Step 1.5: Name the Current Bottleneck\n\nSynthesize the Step-1 analyses into **one sentence naming the single\nmost-limiting pipeline stage right now** — e.g. \"planning\", \"verification\nquality\", \"experiment execution reliability\", \"writing polish\" — with the\nsupporting evidence. The bottleneck always moves: when coding stops being the\nconstraint, planning becomes it; when planning is solved, verification; when\nverification is automated, taste. This step exists to make the CURRENT\nconstraint visible, so Step 2's ranked table reads as sub-fixes for one named\nconstraint instead of scattered tweaks.\n\nAppend the verdict to the append-only ledger `.aris/meta/bottleneck_log.jsonl`\n(same never-mutate discipline as `.aris/runs/<run_id>.iterations.jsonl`):\n\n```bash\nmkdir -p .aris/meta\n# json.dumps, NOT hand-interpolated shell strings: bottleneck/evidence are\n# natural language — a stray quote must not break the JSONL (or the shell).\npython3 - <<'PY'\nimport json, datetime\nentry = {\n    \"ts\": datetime.datetime.now().astimezone().isoformat(timespec=\"seconds\"),\n    \"cycle\": 3,\n    \"bottleneck\": \"verification quality\",\n    \"evidence\": \"review rounds plateau at 6/10 while tool failures are rare\",\n    \"top_patch_ids\": [\"P1\", \"P2\"],\n}\nwith open(\".aris/meta/bottleneck_log.jsonl\", \"a\", encoding=\"utf-8\") as fh:\n    fh.write(json.dumps(entry, ensure_ascii=False) + \"\\n\")\nPY\n```\n\nNever edit or delete prior lines — succession history is the point.\n\n### Step 2: Identify Optimization Targets\n\nBased on Step 1, rank optimization opportunities by expected impact:\n\n```markdown\n## Optimization Opportunities (ranked)\n\n| # | Target | Signal | Proposed Change | Expected Impact |\n|---|--------|--------|-----------------|-----------------|\n| 1 | auto-review-loop default threshold | Users override to 7/10 in 60% of runs | Change default from 6/10 to 7/10 | Fewer manual overrides |\n| 2 | experiment-bridge retry count | 40% of runs hit max retries on OOM | Add OOM-specific recovery (reduce batch size) | Fewer failed experiments |\n| 3 | paper-write de-AI patterns | Users manually fix \"delve\" in 80% of runs | Add \"delve\" to default watchword list | Fewer manual edits |\n| 4 | experiment-bridge Phase-2 hand-holding steps | Model bump (session_start model changed); scaffold untouched since 2 generations ago; zero tool_failures in the steps it guards | **DELETE steps N–M — the new model does this unprompted** | Smaller harness, less drift surface |\n```\n\nThe Proposed-Change column is explicitly allowed to be a **deletion** — \"DELETE\nstep N, new model does this for free\" is a first-class optimization, ranked by\nthe same impact logic as additions.\n\nIf `$ARGUMENTS` specifies a target skill, focus analysis on that skill only.\nIf `$ARGUMENTS` is empty or \"all\", analyze all skills with sufficient data.\n\n### Step 3: Generate Patch Proposals\n\nFor each optimization target, generate a concrete diff:\n\n```diff\n--- a/skills/auto-review-loop/SKILL.md\n+++ b/skills/auto-review-loop/SKILL.md\n@@ -15,7 +15,7 @@\n ## Constants\n \n-- **SCORE_THRESHOLD = 6** — Minimum review score to accept.\n+- **SCORE_THRESHOLD = 7** — Minimum review score to accept. (Raised based on usage data: 60% of users overrode to 7+.)\n```\n\n**Rules for patch generation:**\n- One patch per optimization target\n- Each patch must include a comment explaining WHY (with data from the log)\n- Patches must be minimal — change only what the data supports\n- Never change artifact schemas or MCP bridge config in v1\n- Never change behavior that would break existing user workflows\n- **Anti-self-poisoning screen** (see [`shared-references/capture-antipatterns.md`](../shared-references/capture-antipatterns.md)):\n  run a proposed patch's rationale through `tools/capture_filter.py` (resolve via\n  the canonical chain). NEVER propose a change that encodes a **negative\n  tool-capability claim** (\"codex can't…\", \"gemini is broken\") or a **one-off /\n  transient failure** as a durable rule — those harden into self-cited refusals.\n  Encode the *fix / the flag needed / the workaround*, not \"X can't do Y\".\n\n### Step 4: Cross-Model Review of Patches (ADVISORY pre-screen)\n\n> This review is **advisory** — it sharpens the Step-5 REPORT so the human can decide\n> what to stage. It is **not** the landing verdict.

Record this result as\n> `advisory_screen` only.\n\nSend each patch to GPT-6-Astra xhigh for adversarial review:\n\n```\nmcp__codex__codex:\n  model: gpt-6-astra\n  config: {\"model_reasoning_effort\": \"xhigh\"}\n  prompt: |\n    You are reviewing a proposed optimization to an ARIS SKILL.md file.\n    \n    ## Original Skill (relevant section)\n    [paste original]\n    \n    ## Proposed Patch\n    [paste diff]\n    \n    ## Evidence from Usage Log\n    [paste summary stats]\n    \n    Review this patch:\n    1. Does the evidence support the change?\n    2. Could this change hurt other use cases?\n    3. Is the change minimal and safe?\n    4. Score 1-10: should this be applied?\n    \n    If score < 7, explain what additional evidence would be needed.\n\n    === SCOPE LIMITS (these bound what you PROPOSE, never what you look for) ===\n    Report anything that is actually wrong here — including a rare-looking case, if\n    this repo actually produces it. Then keep the fix in scope:\n    1. This is a RESEARCH-WORKFLOW tool, not a security paper. Verification is\n       welcome; over-defense is not. Assume a cooperating operator on their own\n       machine — a malicious local user is NOT in the threat model.\n    2. Do NOT propose SHA / hash / content-fingerprint / digest-binding schemes.\n       Reporting a real defect in hashing code that already exists is fine.\n    3. NO speculative machinery: do not add feature flags, migration frameworks,\n       compat layers, wrappers, pins, or similar mechanisms unless evidence shows\n       a current repo defect they fix or an explicit existing invariant they must\n       preserve. \"Load-bearing\", \"compatibility\", and \"not scaffolding\" are labels,\n       not evidence. Point to the failing path/artifact or invariant, and check the\n       proposal's factual premises, such as whether a named package version exists.\n    4. NO corner-case obsession: exotic encodings, symlink races, RTL text and\n       millisecond races are out of scope unless you can show the case arises here.\n    5. Where a rubric or checklist is genuinely needed, do not over-mechanize\n       judgement. A clear sentence a human reads beats a scored table nobody\n       maintains.\n    Exception: code that runs remote commands, starts a network service, or installs\n    an MCP server runs on the user's machine with their credentials — trust-boundary\n    findings there are in scope and the default is strict.\n    Say plainly when something is correct. Do not manufacture findings.\n```\n\n### Step 5: Present Results\n\nOutput a structured report:\n\n```markdown\n# ARIS Meta-Optimization Report\n\n**Date**: [today]\n**Data**: [N] events, [M] skill invocations, [K] sessions\n**Target**: [skill name or \"all\"]\n\n## Current Bottleneck\n\n**[one-phrase name]** — [one-line evidence]. Prior cycle's bottleneck: [name —\nresolved by <patch ids> / unresolved / first recorded cycle]. (Ledger:\n`.aris/meta/bottleneck_log.jsonl`)\n\n## Proposed Changes\n\n### Change 1: [title]\n- **Target**: [skill/file:line]\n- **Signal**: [what the data shows]\n- **Patch**: [diff]\n- **Reviewer Score**: [X/10]\n- **Reviewer Notes**: [summary]\n- **Status**: ✅ Recommended / ⚠️ Needs more data / ❌ Rejected\n\n### Change 2: ...\n\n## Changes NOT Made (insufficient evidence)\n- [pattern observed but too few samples]\n\n## Recommendations\n- [ ] Apply Change 1 (reviewer approved)\n- [ ] Collect more data for Change 3 (need N more runs)\n- [ ] Consider manual review of Change 2\n\n## Next Steps\nThis skill only **proposes**. To land changes: tell me which to stage, then run\n`/meta-apply` (a separate, human-invoked applier that re-checks the cross-model\nverdict before mutating anything). meta-optimize never applies.\n```\n\n### Step 6: Stage approved patches for `/meta-apply` (NO in-skill apply)\n\nThis skill does **not** apply anything. After the user has read the Step-5 REPORT and\nindicated which changes to land, **stage** them for the privileged applier:\n\n1. For each approved change `N`, write its unified diff to\n   `.aris/meta/pending/<NN>_<skill>.diff` and append a row to\n   `.aris/meta/pending/manifest.jsonl`:\n   `{patch: \"<NN>_<skill>.diff\", target: \"<corpus path>\", author_model: \"<executor>\",\n   advisory_screen: \"pass|kill\", advisory_reason: \"<one line>\"}`.\n   The `advisory_screen` (your Step-4 codex pre-review) is **advisory only** — it helps\n   the human read the REPORT. It is **NOT** the landing verdict and `/meta-apply` does not\n   trust it: a producer-written verdict would be forgeable. The binding cross-model jury\n   runs **at landing, inside `/meta-apply`,** on the actual staged diff.\n2. Tell the user: *\"Staged M patches. Run `/meta-apply` to judge & land them.\"*\n\nThe backup → **fresh jury-at-landing** → apply → **provenance stamp** → log all happen\ninside [`/meta-apply`](../meta-apply/SKILL.md). meta-optimize never touches the corpus and\nnever produces the acquittal.\n\n**Never apply in this skill. Landing is `/meta-apply` + a fresh jury + a human, always.**\n\n## Key Rules\n\n- **Log-driven, not speculative.** Every proposed change must cite specific data from the event log. No \"I think this would be better.\"\n- **Minimal patches.** Change one thing at a time. Don't rewrite entire skills — the one sanctioned large edit is a scaffolding **deletion** backed by TARGET-SPECIFIC model-delta evidence (a capability-specific release note, or repeated post-bump event-log behavior showing the scaffold is unused — the model name changing is a trigger to look, never sufficient evidence). Privilege boundaries, acceptance gates, corpus/provenance rules, output contracts, and safety checks are never deletion candidates. Deletions go through the same review + approval gates as everything else.\n- **Reviewer-gated.** Every patch goes through cross-model review before recommendation.\n- **Reversible.** Always back up before applying. Always log what changed.\n- **User-approved.** Never auto-apply. Present, explain, let the user decide.\n- **Honest about uncertainty.** If the data is insufficient, say so. Don't optimize on noise.\n- **Portable.** Optimizations should improve the skill for all users, not just one user's style. If a change seems user-specific, flag it.\n\n## Event Schema Reference\n\nThe log at `.aris/meta/events.jsonl` contains JSONL records with these shapes:\n\n```jsonl\n{\"ts\":\"...\",\"session\":\"...\",\"event\":\"skill_invoke\",\"skill\":\"auto-review-loop\",\"args\":\"difficulty: hard\"}\n{\"ts\":\"...\",\"session\":\"...\",\"event\":\"PostToolUse\",\"tool\":\"Bash\",\"input_summary\":\"pdflatex main.tex\"}\n{\"ts\":\"...\",\"session\":\"...\",\"event\":\"codex_call\",\"tool\":\"mcp__codex__codex\",\"input_summary\":\"review...\"}\n{\"ts\":\"...\",\"session\":\"...\",\"event\":\"tool_failure\",\"tool\":\"Bash\",\"input_summary\":\"python train.py\"}\n{\"ts\":\"...\",\"session\":\"...\",\"event\":\"slash_command\",\"command\":\"/auto-review-loop\",\"args\":\"\"}\n{\"ts\":\"...\",\"session\":\"...\",\"event\":\"user_prompt\",\"prompt_preview\":\"change difficulty to hard\"}\n{\"ts\":\"...\",\"session\":\"...\",\"event\":\"session_start\",\"source\":\"startup\",\"model\":\"claude-opus-4-6\"}\n{\"ts\":\"...\",\"session\":\"...\",\"event\":\"session_end\"}\n```\n\n## Triggering\n\nThis skill is NOT part of the standard W1→W1.5→W2→W3→W4 pipeline. It is a **maintenance workflow** with three trigger mechanisms:\n\n1. **Passive logging** (always on): Claude Code hooks record events to `.aris/meta/events.jsonl` automatically during normal usage. Zero user effort.\n\n2. **Automatic readiness check** (SessionEnd hook): When a Claude Code session ends, `check_ready.sh` counts skill invocations since the last `/meta-optimize` run. If ≥5 new invocations have accumulated, it prints a reminder:\n   ```\n   📊 ARIS has logged 8 skill runs since last optimization. Run /meta-optimize to check for improvement opportunities.\n   ```\n   It ALSO fires — regardless of invocation count — when the session model has\n   changed since the last optimize (compared against `.aris/meta/.last_optimize_model`):\n   ```\n   🔁 Model changed since last optimization (claude-opus-4-6 → claude-opus-4-8). Run /meta-optimize — a model bump makes existing scaffolding a deletion candidate (harness diet).\n   ```\n   Both are **suggestions only** — they do not auto-run optimization.\n\n3. **Manual trigger**: User runs `/meta-optimize` when they see the reminder or whenever they want.\n\n**After each `/meta-optimize` run**, the skill writes the current timestamp to `.aris/meta/.last_optimize` and the current session model (latest `session_start` event's `model` field) to `.aris/meta/.last_optimize_model`, so the readiness check can detect both new usage and model bumps.\n\n## Acknowledgements\n\nInspired by [Meta-Harness](https://arxiv.org/abs/2603.28052) (Lee et al., 2026) — end-to-end optimization of model harnesses via filesystem-based experience access and agentic code search.\n\n## Output Protocols\n\n> Follow these shared protocols for all output files:\n> - **[Output Versioning Protocol](../shared-references/output-versioning.md)** — write timestamped file first, then copy to fixed name\n> - **[Output Manifest Protocol](../shared-references/output-manifest.md)** — log every output to MANIFEST.md\n> - **[Output Language Protocol](../shared-references/output-language.md)** — respect the project's language setting\n\n## Review Tracing\n\nAfter each `mcp__codex__codex` or `mcp__codex__codex-reply` reviewer call, save the trace following `shared-references/review-tracing.md` (Policy C — forensic; never silently skip).
