description	Deck hygiene pass — retag stale cards, prune 90-day unverified parks, surface defunct references, orphaned dependencies, and jargon titles. AUTO-INVOKE on "tidy up the deck", "hygiene pass", "clean up the queue", or /refine-deck. The board itself gets refactored each iteration.

When to invoke

Invoke when the user says "tidy up the deck", "check for stale cards", "hygiene pass", "clean up the queue", "archive old", "audit the deck", or invokes /refine-deck. Covers retagging stale cards, pruning 90-day unverified parks, surfacing defunct file:line references, surfacing orphaned dependencies (epics with no children, meta-fix families not wired, log.md migration TODOs), surfacing engineer-jargon titles for retitling, and proposing new canonical tags (XP refactor mercilessly + Kanban continuous improvement).

Preflight

If any ! block below shows goc: command not found, Permission for this action has been denied, or no such file or directory: .game-of-cards/deck/, stop and invoke Skill(kickoff) first. Kickoff detects which setup step is missing (CLI not installed, Bash allowance not granted, project state not scaffolded) and walks the user through it. Re-invoke this skill only after kickoff completes.

Context (project-local extension)

!cat .game-of-cards/hooks/refine-deck.md 2>/dev/null || true

Refine the deck

Every iteration the BOARD gets better, not just the code on it: this skill is the recurring hygiene tax that keeps the deck's read-pattern guarantee alive as filing slows down and rot accumulates. The hook above may extend the flow with project-specific categories or thresholds (scope rules in reference.md § Rationale).

Surface rot and act on it before commit. Two action paths depending on the finding's nature:

• Hygiene findings (mechanical: stale unverified parks, defunct file:line cites, missing summaries, orphaned-edge mechanical wires) — apply the edit directly; a non-firing tag row is the one exception, reported and never edited.
• Structural findings (epic-shaped clusters, missing canonical-reference families, contribution-recall proposals, meta-decision umbrellas, newly-emergent tag candidates surfaced by a project hook's pattern-discovery pass) — file via Skill(create-card), disprove via Skill(advance-card) <title> disproved, or park --tag unverified per Step 4.5. "Surfaced and discussed in chat" is not a disposition.

Long-form material lives in reference.md — a sibling file in this skill's directory. Read the named section only when the situation actually applies:

Step 1 — sanity floor

!b=.claude/skills/_goc-bootstrap.sh; if [ -f $b ]; then sh $b validate; else goc validate; fi 2>&1 || echo "[refine-deck] validate found rot; the skill body below will route you through fixing it"

If validate fails with half-edge errors, run goc repair-edges to preview the missing reverse-edge writes, then goc repair-edges --apply and re-run goc validate. If repair reports a structural cycle, park that card for human review instead of guessing which edge is wrong. Fix unknown tags / missing required fields FIRST too. Hygiene runs on a valid deck. The precondition above is intentionally soft-gated so a failing validator surfaces its output into this skill rather than blocking the skill load.

Step 2 — survey by category

Stale unverified parks

!b=.claude/skills/_goc-bootstrap.sh; if [ -f $b ]; then sh $b --tag unverified -v; else goc --tag unverified -v; fi 2>&1 || true

For each entry: check created against today's date. Cards parked

90 days that nobody has reproduced or refuted are decay candidates. Options:

• Retry the falsifying recipe. If the body's "what-evidence-would-falsify-it" recipe is now feasible (infra exists, sweep budget available), run it. On evidence: drop the unverified tag (promote) or flip to disproved.
• Demote to disproved. If three independent rounds have failed to reproduce, the lead is dead. Skill(advance-card) <title> disproved with a one-line "Three rounds attempted; no reproduction" rebuttal.
• Keep parked. Add a one-line note in log.md explaining why this round didn't have the budget; the 90-day clock resets.

Stale-open cards (no log activity)

!b=.claude/skills/_goc-bootstrap.sh; if [ -f $b ]; then sh $b --status open --json; else goc --status open --json; fi 2>&1 | head -100

Cards with status: open whose log.md has no entries in 60+ days are at risk of being forgotten. For each: read the body, decide if the lead is still real, and either:

• Re-prioritize via Skill(next-card) (recommend it on the next loop iteration).
• Escalate the gate from none to decision if blocking on a framing question.
• Flip to disproved if the original evidence has rotted away.

Defunct file:line citations

Check each open card's cites against current code with an ANCHOR test, not a bounds test. An in-range line number is no evidence the cite is current: a file that grew keeps every old number valid while the code that was there moved down, so line ≤ EOF can only fire on a file that SHRANK. Compare what is AT the cited line now against what the card says is there. Per cite (long form: reference.md § Citation anchor check):

1. Resolve the path — cards write engine.py:N for goc/engine.py:N; prefer a non-mirror match. Ranges map both endpoints.
2. Anchor = that line's text at the commit that last WROTE the number: walk git log --follow --format=%H -- <card>/README.md oldest → newest and take the newest commit where the cite token turns from absent to present — the filing commit for a virgin cite, the repair commit for one an earlier pass rewrote. Anchoring a repaired number at the filing commit reads unrelated code and moves the cite onto it.
3. Anchor ≠ the line in HEAD → the cite is defunct.
4. Relocate the anchor text in HEAD and rewrite the number only on a unique match of a non-trivial line (>~12 chars, not a blank or a bare brace). Never guess.

Cites step 4 declines — anchor gone, ambiguous, or trivial — are REPORTED for a human to read, never silently skipped. Anchor text that exists nowhere usually means the cited code was refactored away: re-read the card and, if the refactor also fixed the defect, close via Skill(finish-card) with a note "fixed incidentally by ".

Missing summaries

Pre-2026-05-01 cards may have empty or absent summary: fields. Surface these:

goc --status all --json | \
  jq '.[] | select(.summary == "" or .summary == null) | .title'

For each surfaced card: read the body, write a ≤3-sentence summary into the frontmatter. Mechanical doc edit; no status change.

Tags without firing predicates

Per Skill(card-schema), a tag must satisfy its own row, not a fixed text window; the row's check column says whether that is scorable or a judgment (reference.md § Tag sweeps). Survey 5–10 random cards per round. Report, never strip — a non-firing row costs a line of output, not curated grouping.

Orphaned dependencies

Relational rot the validator cannot see: it enforces edge SYMMETRY at commit time but not edge ABSENCE — epics with zero linked children; meta-fix cards whose body lists a family roster but carry zero edges; open cards with legacy **Depends on:** / **Next:** / **Part of:** body markers but empty schema arrays; unactioned log.md migration TODOs (formerly parent: X / formerly spawned_from: X). Run the four sub-checks in reference.md § Orphaned-dependency sub-check scripts, judge each surfaced card's edge direction, and wire it via goc advance X --by Y (symmetric-by-construction, so the validator stays happy). A card whose family members are code sites has nothing to wire — leave it.

Card metadata quality pass

Title antipatterns + missing-summary scan via:

goc quality-pass --status all

What it surfaces:

• Title antipatterns — same regex predicates goc new uses to reject filings (engineer-jargon: r88, path-2, phase-3, bug-140, _md_/_py_ infixes, camelCase tokens, math symbols). Catches legacy cards filed before the antipattern guard was wired. For each surfaced title: rename via goc move <old> <new> so cross-references rewrite atomically.
• Missing summaries — pre-2026-05-01 cards may lack the summary: frontmatter field that triage views (goc -v) depend on. For each: read the body, write a ≤3-sentence summary into the YAML.

Step 3 — file new canonical tag candidates

When a coherent body of work emerges that isn't covered by an existing tag (e.g., a sprint of 6 cards all about a specific research front), file via Skill(create-card) a card whose DoD is the SCHEMA.md PR adding the new tag + its predicate. Adding the tag itself remains a SCHEMA.md PR per the schema's "Adding new tags" rule; the filing that schedules that PR is imperative. Like every other structural finding, the candidate either becomes a card here, gets disproved (the proposed predicate doesn't fire on a sufficient set), or parks --tag unverified per Step 4.5 — not a chat-only proposal.

Step 4 — surface and act

For each surfaced issue, output one line documenting the action taken (hygiene) or the card filed / disprove flip / park (structural):

<title>: <issue> → <action>

Sample lines in reference.md § Example Step 4 output.

Step 4.5 — Park-or-disprove unfollowed structural candidates (mandatory)

Project hooks may extend Step 2 with a pattern-discovery pass that surfaces more structural candidates than this round can verify and file. Structural candidates that didn't get applied this round MUST go somewhere durable before commit:

1. Filed as a new card via Skill(create-card).
2. Disproved via Skill(advance-card) <title> disproved — when you re-read the cited code and the candidate is wrong on its face.
3. Unverified via Skill(create-card) ... --tag unverified — when the candidate has substance but no verification budget this round. Body must include: the candidate's hypothesis with file:line (verbatim quote), why deferred, falsification recipe, the category (Step 2 sub-section) that surfaced it.
