anthropic-grade-optimizer

name	anthropic-grade-optimizer
description	Audits and optimizes Claude-directing artifacts (CLAUDE.md, SKILL.md, subagent, hook, MCP config, system or user prompt, workflow, api_config) against 189 cited Anthropic rules across 11 dimensions, calibrated per model (Opus 4.7, Sonnet 4.6, Opus 4.6, Haiku 4.5). Every finding ships with verbatim quote and source URL; authorial voice is preserved.
when_to_use	Operator asks to audit, optimize, review, lint, score, refactor, or "make Anthropic-grade" any prompt, CLAUDE.md, SKILL.md, subagent, hook, MCP config, api_config, or workflow. Also triggers on model migration ("good for Opus 4.7?", "optimize for Haiku"), compliance review, or fixing adherence/verbosity/hallucination drift in a Claude artifact.

Anthropic-Grade Optimizer

Audits any Claude-directing artifact against the official Anthropic doctrine, calibrates findings by target model, and proposes surgical optimizations that preserve authorial voice. Every finding cites a verbatim source URL; the skill ships with cited rules only.

Hierarchy of authority

Anthropic doctrine is the sole source of scoring rules. Optional interpretive lenses inform how to reason about findings (what to preserve, when to defer, how to phrase recommendations) — they stay outside the rubric. On collision, Anthropic always wins.

Honest scope

189 unique cited rules across 11 dimensions, each with a verbatim quote and source URL. Read references/rules-anthropic.yaml § meta.total_unique_rules for the canonical count — every other counter in the skill must read from there to prevent drift. Rules with deterministic detection (regex, code-check) are audited automatically by scripts/pass1_mechanical.py. Rules with qualitative criteria (llm-judge, heuristic) are audited by following references/pass2-protocol.md. Coverage gaps and known limitations live in references/gaps.md and must appear in the coverage_caveat block of every report.

Pass-1 deterministic coverage in v1.2: ~52 rules (~28% of 189). Pass-2 covers the remaining ~137 qualitative rules. Hybrid detection is supported via the requires_pass2_grade flag on findings.

Quick start

Canonical entry point (default):

python scripts/run.py <artifact_path> --target opus-4-7 --mode audit

The orchestrator chains classify → pass 1 → score → emit, and surfaces Pass 2 prompts for the LLM. This is the single right answer for ~95% of audits.

Manual flow is for one specific case: an operator forcing fine-grained control over a single phase (re-running pass 1 only, scoring an external findings file, debugging the classifier). Do not use it as a parallel path — the orchestrator is the contract.

1. Ingest — receive the artifact path or content, target model (default opus-4-7), mode (default audit).
2. Classify — Run scripts/classify_artifact.py to detect artifact type and load the rule subset from references/rubric-by-type.yaml.
3. Audit — Pass 1 mechanical via scripts/pass1_mechanical.py. Pass 2 qualitative reasoning following references/pass2-protocol.md against references/rules-anthropic.yaml.
4. Diagnose — Classify each finding as 🔴 must-fix, 🟡 should-fix, 🟢 may-fix, ❓ open-question, or ⚪ preserve (authorial voice).
5. Optimize (when mode = optimize or full) — Produce surgical diffs per references/pass2-protocol.md § Diff Generation. Each diff cites source_url + verbatim_quote. When a rule has a canonical snippet, emit a verbatim patch from assets/snippets/ rather than paraphrasing.
6. Validate (when mode = full) — Re-score post-diff; abort when a hard rule is introduced or voice drift exceeds 10%.
7. Emit — Concise report (summary + scorecard + diff). Verbose mode adds reasoning trail, preservation log, and open questions.

Worked example 1 — auditing a SKILL.md for Opus 4.7

Operator request: "audit this skill for Opus 4.7" Artifact: `~/.claude/skills/pdf-tools/SKILL.md` (240 lines)

Step 1 — Classify: type=skill, has_frontmatter=true, body_lines=235. Step 2 — Load rubric: 24 D-SKILL rules + 17 D-CLAR + 10 D-STRUCT + 8 D-EXAMPLE + 5 D-EVAL + safety. Suppress AR-CC-S09 doctrine-conflict? No (skill body). Step 3 — Pass 1 fires: AR-CC-S20 (lib mentioned without pip install), AR-CC-S22 (3 script refs unframed), AR-CLAR-006 (7 negatives, 1 positive alt). Step 4 — Triage: 1 🔴 (AR-CC-S20), 2 🟢 (S22, CLAR-006). Step 5 — Optimize emits snippet patches: none (no rule with canonical snippet fires). Inline diff for AR-CC-S20 adds "Install required package: pip install pypdf". Step 6 — Validate: post-diff score 92 (was 78). Voice drift 4% — under 10% gate. Step 7 — Emit concise report.

Worked example 2 — strange-loop self-audit

Operator request: "run the skill on its own SKILL.md" Artifact: `anthropic-grade-optimizer/SKILL.md`

Step 3 — Pass 1 fires: AR-CC-S14 (name contains "anthropic" reserved word) and possibly AR-CC-S21 (TOC) and AR-CC-S22 (script framing). Step 4 — AR-CC-S14: see § Self-audit: Open Questions below for the operator's documented decision (semantic-justification exception). Step 5 — No-op for the AR-CC-S14 finding (declared exception). Step 7 — Concise report flags the open question and links to the §.

Worked example 3 — auditing an api_config snippet

Operator request: "is this Python snippet safe for Opus 4.7?" Artifact: a `client.messages.create(...)` call with `temperature=0.7`, `effort='low'`, last message role=assistant. Type: `api_config`. Target: `claude-opus-4-7`.

Step 3 — Pass 1 fires: AR-MODEL-002 prefill (HARD, last role=assistant); AP-15 sampling param temperature (HARD); AR-REASON-017 effort=low on opus-4-7 with coding signal (severity_amplification → HARD); AR-MODEL-021..025 emitted as one Open Question with 5 options (collapsed via open_question=True). Step 4 — Triage: 3 🔴 (002, AP-15, REASON-017), 1 ❓ (021..025). Step 5 — Optimize emits inline diffs for AR-MODEL-002 / AP-15 (remove sampling params, move continuation to user message per AR-MODEL-024 if that pattern is the operator's choice).

The Three Laws

These three laws encode the discipline that separates Anthropic-grade from "looks rigorous":

1. Cite or stay silent. Every 🔴 / 🟡 finding carries a source_url. When a source is absent, the finding is downgraded to EXTERNAL_ENRICHMENT or dropped — Anthropic-grade ships only cited rules.
2. Artifact type comes first. Apply the rule subset for the detected type. Firing a SKILL.md rule against a CLAUDE.md is a false positive — see references/rubric-by-type.yaml § false_positive_rules.
3. Voice drift trumps score. Raising the score by diluting the operator's voice is a regression in disguise. Optimizations with voice_drift > 10% abort; with --push-ceiling the gate tightens to 5%.

Artifact types (9)

Detection happens on filename plus content; each type loads a tailored rule subset from references/rubric-by-type.yaml:

Type	Path signal	Primary dimensions
claude_md	CLAUDE.md, CLAUDE.local.md	D-CC (memory), D-CLAR, D-STRUCT
skill	SKILL.md in skills/<name>/	D-CC (skill), D-CLAR, D-STRUCT
slash_command	.claude/commands/<name>.md (legacy)	D-CC (skill subset)
subagent	.claude/agents/<name>.md	D-CC (subagent), D-AGENT, D-CLAR
hook_config	settings.json hooks key	D-CC (hooks)
mcp_config	.mcp.json, .claude.json	D-CC (mcp)
system_prompt / user_prompt	inline / API artifact	D-CLAR, D-STRUCT, D-EXAMPLE, D-REASON, D-CONTEXT, D-MODEL, D-TOOL, D-VISION
api_config	Python/JSON snippet with client.messages.create or model="claude-..."	D-MODEL, D-REASON, D-CONTEXT (cache), D-TOOL, D-VISION
workflow	YAML pipeline	D-AGENT, D-EVAL

Target-model modulation

Each model has a profile cell in references/modulation-matrix.yaml. Critical anti-patterns flagged automatically:

• Opus 4.7 — rejects temperature / top_p / top_k (HTTP 400), rejects manual thinking:{enabled,budget_tokens} (400), rejects prefill on the last assistant turn (400). Interprets prompts literally — state scope explicitly. ALL-CAPS imperatives over-suppress output. Effort levels are strict; pair xhigh with coding/agentic. Tool use decreases by default; raise effort or prompt explicitly when more tool use is wanted.
• Opus 4.6 / Sonnet 4.6 — rejects prefill (400). Adaptive thinking is recommended.
• Haiku 4.5 — adaptive thinking unsupported, effort parameter unsupported, 200k-token context. Needs maximum explicitness; few-shot is more critical (5+ examples).

When a target model lacks a profile (e.g., a new release), inherit from the closest sibling and stamp the report with confidence: low. Fallback rules live in references/modulation-matrix.yaml.

The 11 dimensions

Dim	Focus	Weight
D-CLAR	Clarity, directness, positive framing	16%
D-STRUCT	XML tags, hierarchy, formatting	11%
D-EXAMPLE	Few-shot 3-5 examples in <example>	8%
D-REASON	CoT, adaptive thinking, self-check	12%
D-CONTEXT	Doc placement, grounding, cache	10%
D-MODEL	Model-specific calibration	10%
D-AGENT	Stop conditions, ground truth, delegation	8%
D-EVAL	Verification embedded in prompt	7%
D-TOOL	Tool definitions, schemas, parallel	6%
D-VISION	Image placement, coords, formats	4%
D-CC	Claude Code ecosystem (memory/skill/agent/hook/MCP)	8%

Severity → triage

Severity	Score impact	Triage
hard / critical / never	-10 to -20	🔴 must-fix
soft / high	-5 to -8	🟡 should-fix
medium	-3 to -5	🟡 should-fix
low / warning	-1 to -2	🟢 may-fix
(5+ migration options, group fix)	n/a	❓ open-question
(authorial voice signal)	n/a	⚪ preserve

Emphasis conflict (D9, type-aware)

Two Anthropic sources disagree about ALL-CAPS / IMPORTANT / YOU MUST:

• code.claude.com/docs/en/best-practices endorses emphasis to tune adherence.
• github.com/anthropics/skills/skill-creator flags ALL-CAPS as yellow, preferring an explanation of the underlying reason.

Resolution applies by artifact type:

Artifact type	Emphasis verdict
claude_md, system_prompt, user_prompt	Endorsed (suppress yellow-flag finding)
skill, subagent body	Yellow flag (raise finding, explain WHY)
tool_description	Neutral (no doctrine)

When AR-CC-S09 fires on a claude_md, suppress it as a false positive (anti-pattern AP-10).

Detection methods

Prefer determinism (cheapest instrument that solves):

• regex / code-check → scripts/pass1_mechanical.py
• heuristic (line counts, structural shape) → scripts/pass1_mechanical.py
• hybrid (regex emits candidate, LLM grades substance) → Pass 1 emits with requires_pass2_grade=true; Pass 2 finalizes
• llm-judge → reason directly with the artifact text loaded; cite the rule + verbatim quote

Reach for llm-judge only when no script can decide.

Operating modes

• audit (default) — read-only report, no diffs proposed.
• optimize — generate diffs without validating.
• full — audit → optimize → validate → emit. Loops up to three passes when score < 85.
• --push-ceiling — applies may-fix (🟢) findings; tightens voice_drift to 5%.
• --fast — top-5 findings only; single pass.
• --no-exceptions — disables operator-declared exceptions (see § Self-audit). Reports the strict raw score instead of the active score. The orchestrator always shows both side by side when an exception is in effect, so this flag is for downstream tooling that needs the unadjusted number.

Adaptive modes (auto-trigger)

Trigger	Mode	Effect
Artifact > 800 lines	STRATIFIED-AUDIT	Map blocks → triage → deep-audit top-K (default K=5)
Initial score ≥ 85 + zero 🔴	AFFIRMATION	Short report; surface 🟢 only with --push-ceiling
Artifact < 50 tokens + minimal markers	HIGH-UNCERTAINTY	Ask "intentional brevity or unfinished?" before expanding
Target model lacks profile	FALLBACK-MODEL	Inherit sibling, mark INFERRED, reduce D-MODEL weight 10% → 5%

Verbose adds: per-finding reasoning trail, preservation log (what stayed and why), and explicit open questions for authorial decisions.

Workflow

1. Run python scripts/classify_artifact.py <path> → {type, line_count, signals}.
2. Read references/rubric-by-type.yaml for the type's rule_ids.
3. Run python scripts/pass1_mechanical.py <path> --type <type> --target-model <model> → deterministic findings (including hybrid candidates).
4. For each rule with detection_method=llm-judge in the type's subset, read the relevant section, reason about adherence, cite the rule's verbatim_quote, and append the finding to the bundle.
5. Apply D9 emphasis-conflict resolution by artifact type (see references/rubric-by-type.yaml § false_positive_rules).
6. Run python scripts/score_calculator.py <findings.json> → {score, per_dimension, voice_drift_estimate}.
7. Triage findings (🔴/🟡/🟢/❓/⚪).
8. When mode ≠ audit, run python scripts/optimize.py <path> --findings <json> --type <type> to produce surgical diffs and snippet patches (each cited).
9. When mode = full, simulate post-diff, re-score, validate gate.
10. Emit report (concise default; verbose with --verbose).

Scope discipline (positive framing)

This skill audits prompts and Claude-directing artifacts. Its responsibilities:

• Audits: cited findings only, with verbatim_quote + source_url.
• Proposes diffs: surgical, one rule per diff, voice-preserving.
• Stays in source language: preserves the artifact's authorial voice.
• Defers to operator: the operator stays in the editor's seat — diffs apply only with --apply to an <path>.optimized.<ext> sibling, never overwriting the original.

Out-of-scope (sibling tools handle these):

• Evaluating Claude's responses — that work belongs to eval pipelines.
• Auditing application code that consumes the Claude API beyond the prompts and artifacts themselves.
• Inventing rules without a source URL — every finding ships cited.

Edge cases

When a rule could fire but no verbatim source quote can be found, hold the finding back. Add it to the report's coverage_caveat block as a candidate for the next dissection round. Anthropic-grade means cited or silent.

When two rules conflict and no documented resolution exists (see references/gaps.md for the 10 known conflicts), surface both findings and elevate the decision to the open questions block — the operator decides.

Self-audit: Open Questions

The skill audits itself on every release via the canonical entry point:

python scripts/run.py SKILL.md --target opus-4-7 --mode audit

Declared exceptions (operator-justified, registered in scripts/run.py § DECLARED_EXCEPTIONS):

• AR-CC-S14 — reserved word "anthropic" in name. The doctrine quote "Cannot contain reserved words: 'anthropic', 'claude'." applies to skill names. The operator decision is to keep the name anthropic-grade-optimizer because it is the most precise descriptor of the skill's purpose. A rename to doctrine-grade-optimizer would lose the explicit doctrinal anchor and degrade trigger reliability for operators searching by domain. The Pass-1 detector continues to flag it on every run; the orchestrator splits the report into active score (exception applied) and raw score (--no-exceptions) so consumers retain full information. D-CC dimension shows the residual penalty transparently — voice fidelity over hidden adjustment.

The full self-audit run, including findings, both scores, and dimension breakdown, is committed at evals/SELF-AUDIT.md and re-runs on every release.

• rules-anthropic.yaml — 189 rules with source_url + verbatim_quote + detection_method (v1.2). The canonical SSOT for rule count and content.
• rules-master.yaml — index by dimension (points into rules-anthropic.yaml).
• modulation-matrix.yaml — 4 models × ~10 cells, each {value, source_url, confidence}.

Assets (canonical snippets)

• assets/snippets/ — 18 canonical snippets (16 rule-bound + 2 advisory). Every snippet is byte-by-byte verbatim from the live Anthropic doc, with a header table declaring triggers_rule, applies_to, model_specific, source_url, insertion_pattern, and voice_drift. Snippets cover high-leverage rules: AR-MODEL-018 (code-review coverage), AR-MODEL-011 (investigate before answering), AR-MODEL-007/AR-AGENT-009 (parallel tool calls), AR-CLAR-011 (action vs research posture, two snippets), and 12 more.
• assets/snippets/index.yaml — rule_id → snippet map consumed by scripts/optimize.py. Type-aware suppression prevents AP-9 false patches (e.g., subagent files never receive subagent-orchestration snippets).

Scripts (6 entry points in scripts/)

• run.py — orchestrator; runs classify → pass 1 → score → emit. Single entry point for most workflows.
• classify_artifact.py <path> — returns {type, line_count, language, has_frontmatter, signals}.
• pass1_mechanical.py <path> --type <type> --target-model <model> — emits findings array (regex + code-check + hybrid candidates).
• score_calculator.py <findings.json> — emits {score, per_dimension, voice_drift_estimate}.
• optimize.py <path> --findings <json> --type <type> [--apply] — emits diffs and snippet patches; with --apply writes to <path>.optimized.<ext> (preserving the original).
• run_eval_suite.py — replays evals/fixtures/ ground-truth suite.

All scripts use forward slashes and read paths via the CLAUDE_SKILL_DIR env var, defaulting to the parent of the script directory (per AR-CC-S06). On Windows, scripts force UTF-8 stdout to render the triage glyphs (🔴/🟡/🟢/❓/⚪) without cp1252 crashes.

Validation (eval suite + strange-loop)

The skill validates itself via evals/. The fixture set covers good / bad / adversarial-minimal cases for every artifact type, plus cross-type fixtures that exercise the false-positive suppression matrix. Ground-truth scores live in evals/ground-truth.yaml; scripts/run_eval_suite.py replays them. The strange-loop self-audit (evals/SELF-AUDIT.md) re-runs the skill against its own SKILL.md on every release and commits the result for transparency.
