ctx-kb-site-review

name	ctx-kb-site-review
description	Mechanical structural audit of the kb. Coerces malformed capitalization, flags malformed closeout frontmatter, and refuses to make judgment calls that require evidence. Writes a site-review closeout for the audit trail.
allowed-tools	Bash(ctx:*), Bash(ls:*), Read, Edit

Site-Review Pass

Walk .context/kb/ and .context/ingest/closeouts/ mechanically. Fix what is unambiguous (capitalization drift, missing frontmatter fields the CLI knows how to coerce). Flag what is not (claims that read as broken but require evidence to fix). Never invent prose. Never mint EV-### rows. Never modify a claim's Confidence band.

This is a janitor pass, not an editorial pass. Editorial judgment lives in /ctx-kb-ingest.

Authoritative background reading: .context/ingest/KB-RULES.md §Authority boundary; specs/kb-editorial-pipeline.md §Validation Rules.

When to Use

• The user says "audit the kb", "check kb for rot", "run a site-review", or invokes the explicit slash form.
• Before a release / handover where structural cleanliness matters.
• After bulk ingest where drift may have accumulated.
• When the doctor advisory has surfaced structural warnings the user wants triaged.

When NOT to Use

• The user wants new material extracted (use /ctx-kb-ingest).
• The user wants kb claims re-grounded against external sources (use /ctx-kb-ground).
• The user is asking a content question (use /ctx-kb-ask).
• The user wants to capture a quick finding (use /ctx-kb-note).

Authority Boundary (vs Other Skills)

• /ctx-kb-site-review: mechanical structural audit. May coerce capitalization that the spec deems lossless (e.g. Confidence: High → high). May flag any other malformation in the closeout's What changed block. May not modify a claim, an EV-### row's content, a Confidence band, a topic page's prose, or a ledger state. Those require evidence judgment.
• /ctx-kb-ingest: handles anything this skill flags as evidence-dependent.
• /ctx-kb-ground: handles anything this skill flags as source-staleness.

Usage Examples

/ctx-kb-site-review

No arguments. The pass walks the kb in full.

Pre-Write Gates

Three distinct refusals, each leaves zero residue:

• .context/ missing → suggest ctx init and stop.
• .context/kb/ missing → suggest ctx init --upgrade and stop.
• Kb scope undeclared (placeholder in .context/kb/index.md) → refuse with the scope message and stop.

Process

1. Verify pre-write gates. Refuse cleanly if any gate fails. Zero residue on refusal.

2. Walk topic pages. For every .context/kb/topics/<slug>/index.md and every sibling sub-page:

   • Status block check: does the page have the four-field Status block (Subject, Last verified, Author, Confidence)? Missing fields → flag in What changed. Do not synthesize.
   • Author field check: Author: hand-authored is prohibited per KB-RULES.md. Flag (do not auto-coerce; human intent matters).
   • Confidence band coercion: high|medium|low|speculative are the only valid values. Coerce capitalization (High → high, MEDIUM → medium) silently and record in What changed. Any other malformation (e.g. Confidence: probable) is flagged for the user.
   • TBD-cite markers: count them per page. The Confidence floor for any page with TBD-cite is speculative. If the page's Confidence is above speculative while TBD-cite is present, flag (do not auto-demote; demotion is evidence work).
   • EV-### citation resolution: every EV-### cited on the page must resolve to a row in .context/kb/evidence-index.md. Unresolved IDs → flag.
   • ## Related concepts in this kb presence: if the page is more than the lede + Status block AND the kb has plausibly adjacent topics, the section should be present. Absence is a soft flag (not auto-fixable).

3. Walk evidence-index.md.

   • Duplicate EV-### IDs: flag every duplicate; name both files / line numbers. The LLM cleanup pass (per spec's P1) handles renumbering, not this skill.
   • Three-digit padding: EV-12 should be EV-012. Flag (do not auto-coerce; renumbering cascades to citations on topic pages, which is ingest work).
   • : same rule as topic pages.

Edge Cases

Case	Expected behavior
.context/ missing	Refuse; suggest ctx init. No residue.
.context/kb/ missing	Refuse; suggest ctx init --upgrade. No residue.
Kb scope undeclared	Refuse with the scope message. No residue.
Zero topic pages on disk	Walk closeouts and ledger anyway. Note the bootstrap state in the closeout. Not a failure mode.
Zero closeouts on disk	Walk topic pages and ledger anyway. Note in the closeout body. Not a failure mode.
Confidence: High (capitalization drift)	Coerce to high silently; record in What changed.
Confidence: probable (unknown band)	Flag for the user; do not coerce.
Author: hand-authored	Flag for the user; do not coerce (human intent matters).
Duplicate EV-### ID across files	Flag both files; defer renumbering to the LLM cleanup pass per spec's P1.
EV-12 (missing zero-pad)	Flag for the user; do not auto-pad (cascades to citations).
Unresolved EV-### on a topic page	Flag; recommend /ctx-kb-ingest <slug> in Next pass hint.
Ledger row Updated predates source file mtime	Flag (lying-to-the-ledger advisory). Do not auto-edit.
Illegal ledger transition (e.g. comprehensive → highlights-extracted without superseded)	Flag; recommend the corrective ingest invocation. Do not auto-correct.
Closeout missing pass-mode frontmatter field	Flag; the handover-fold skips malformed closeouts so the user can fix or delete.
Closeout body's Pass-mode Declared: disagrees with frontmatter pass-mode:	Flag (false-finish signal); recommend hand-edit.
Closeout's Adjacency pre-flight is free prose instead of or a slug-list

Anti-Patterns

• Auto-fixing anything that requires evidence judgment (Confidence promotion/demotion, claim text edits, EV-### renumbering, ledger state changes, prose synthesis).
• Skipping the closeout once pre-write gates pass.
• Hand-editing INBOX.md or SESSION_LOG.md (other skills' surfaces; never this one's).
• Coercing Author: hand-authored to anything else. The user's intent matters; flag and wait.
• Auto-renumbering duplicate EV-### IDs. The cascade to citations is ingest work; this skill flags only.

Output Contract

For pre-write refusals, return only the specified refusal text and stop. No residue.

For passes that clear pre-write gates, end with this structured summary:

• Walked: counts (topic pages, evidence rows, ledger rows, closeouts).
• Coercions applied: count + one-line categories (e.g. "3 capitalization fixes on Confidence bands").
• Flags raised: count + categories (e.g. "2 unresolved EV-### citations; 1 ledger mtime mismatch").
• Closeout: filename on its own line.
• Next-recommended-action: explicit invocations to address each flag category (or none if the kb is clean).

Quality Checklist

Before reporting completion, verify:

• Pre-write gates passed (or the matching refusal was returned with zero residue).
• Every coercion applied is recorded in What changed with file + before/after.
• Every flag is recorded in Flags with file + line + nature.
• No topic-page prose was edited, no EV-### row was modified, no Confidence band was promoted/demoted, no ledger state was changed.
• Closeout written with all required frontmatter fields.
