Compact table of all 56 rules: code + title + 1-line purpose + category + always_on + NEW v7 fields (intents, atomic_set, output_element). Use first to see what exists.

Full text of a single rule by code (R01..R56) + v7 machine metadata (intents, triggers, atomic set + full set members, expected output element). Full text is read from data/rules/rule_texts/.md when migrated; falls back to purpose_1line with a migration note.

Filter the 56-rule table by purpose bucket: structure | lexical | EEAT | unique | all. Specific buckets exclude off-topic rules (R31/R32).

Introspection: intent→rules map, rule→intents map, orphan rules (unreachable via any intent), atomic-set integrity, and matcher trigger inventory. Run after ANY edit to data/*.json. v6 had no such tool — which is how 32 of 56 rules stayed unreachable unnoticed.

Suggest rules for a heading (retriever+suggester, NOT a decider). v7 contract: matched:false means ZERO candidates + disambiguation_questions (no silent generic set). Atomic sets are served COMPLETE (TABLE_SET incl. R14 outro; STEP/LIST incl. R10 outro). why_matched names the exact trigger tokens. For Sales/homepage sections ALWAYS pass section_role — sales headings are benefit statements with no intent keywords and cannot be classified from text alone. expected_document_shape feeds the writing skill's G42 structure-parity gate.

Forbidden Guard — restricted terms + lexical rules (LEX-002/003), payload inlined. Returns records WITH inlined content (v7 payload contract).

ILG Quick Pick — internal-link rules + examples (PI 6.3.034/035), payload inlined. Returns records WITH inlined content (v7 payload contract).

Tech QA — technical SEO signals. Returns records WITH inlined content (v7 payload contract).

Topical Strategy — topical mapping guidelines. Returns records WITH inlined content (v7 payload contract).

Quality Control — validation + system status. Returns records WITH inlined content (v7 payload contract).

Extract metadata from knowledge .md files (GKB_KB_DIR) into gkb_index.jsonl (GKB_INDEX_PATH). v7: clean title extraction — skips markdown noise and AI-conversation openers, prefers the first real heading. The only tool that writes by default; degrades to in-memory with a warning if the index path is not writable.

Summarise the index: totals by family, type, language. PURE READ — result returned in the response (v6 crashed with EPERM trying to write gkb_manifest.json into CWD). Pass persist:true to also snapshot into GKB_OUTPUT_DIR (best-effort, warns on failure).

Filter metadata-only records by family/type/tag/keyword/pi_code/id (stateless, no full content).

Progressive disclosure: pipe-delimited rows id|family|type|title (~50-100 tokens). Follow with gkb_query or gkb_read_kb_content on the ids you need.

Read full content from a KB file — v6 contract preserved: {filename, offset, limit} line-based → {content, total_lines, has_more}. v7: filename also accepts a record id (e.g. LEX-002); path resolves via GKB_SEO_ROOT/KB or GKB_KB_DIR (v6 hardcoded __dirname/KB and ignored the env root).

Jaccard keyword similarity between one record and the rest of the index.

Check all indexed files exist and SHA256 hashes match. PURE READ — returns {ok, missing, hash_mismatches} in the response (v6 crashed writing runlog.json to CWD). persist:true snapshots to GKB_OUTPUT_DIR, best-effort.

Execute multiple operations in one call — types: query | smart_orchestrate | micro_query | validate | manifest. Response keeps the v6 envelope {summary,results,errors,timestamp}. smart_orchestrate ops accept v7 params (section_role, intent_override, unique_angle, max_intents).

Orchestrate rules for MULTIPLE headings in one call (whole outline / whole homepage). Each item accepts the full v7 orchestrate params. include_relations:true adds shared-rule analysis across headings (which atomic sets repeat, which intents dominate) — useful for structure variety checks.

Analyze multiple text targets: mode 'keyword_extraction' (top domain keywords per text), 'rule_mapping' (orchestrate per text = heading), or 'content_analysis' (length + KB keyword overlap). Kept from v6 for compatibility.
