next-card

name	next-card
description	Pick the highest-leverage open card to work on next. Read-only verdict — does NOT flip status (pull-card claims). AUTO-INVOKE on "what's next", "pick something", "what should I do", or autonomous-loop work. Filters to `human_gate: none` for loop safety.

Codex GoC Command

When this skill says goc ..., resolve the executable before running the command:

• In the game-of-cards source checkout, use uv run goc ....
• If goc is already on PATH, use goc ....
• If this skill is loaded from the Game of Cards Codex plugin, use the bundled helper at <plugin-root>/skills/_goc-bootstrap.sh ...; the plugin root is the parent directory that contains both skills/ and bin/.
• If the plugin root is not obvious from the loaded skill path, locate the helper with:

GOC_BOOTSTRAP=$(find "$HOME/.codex/plugins/cache" -path '*/game-of-cards/*/skills/_goc-bootstrap.sh' -type f -perm -111 -exec ls -t {} + 2>/dev/null | head -n 1)
test -n "$GOC_BOOTSTRAP" || { echo "GoC Codex plugin bootstrap not found" >&2; exit 127; }
"$GOC_BOOTSTRAP" --help

Use that helper path in place of bare goc for the rest of the skill. Do not edit deck files directly just because goc is not on PATH.

When to invoke

Invoke when the user says "what's next", "pick something", "work on the queue", "what should I do", "next item", "drain the deck", or initiates autonomous-loop work. Kanban pull principle — work is taken, not pushed.

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

!b=.claude/skills/_goc-bootstrap.sh; if [ -f $b ]; then sh $b --status active -v; else goc --status active -v; fi 2>&1 | head -20

!b=.claude/skills/_goc-bootstrap.sh; if [ -f $b ]; then sh $b --ready -v${GOC_WORKER:+ --worker "$GOC_WORKER"}; else goc --ready -v${GOC_WORKER:+ --worker "$GOC_WORKER"}; fi 2>&1 || true

Pick the next card

Kanban's pull principle (Anderson): work is taken when capacity is ready, not pushed by a planner. The runner — human or autonomous loop — pulls one card at a time, top of the value-sorted queue, gated by the autonomy ladder so a cron run cannot accidentally land a research-impacting decision unsupervised. The deck is the queue; this skill is the picker.

Recommend, do not claim. Status does NOT flip here — that is Skill(advance-card)'s contract. The pull is a two-step gesture (pick, then claim) so the human or /loop can abort between them without half-state on disk.

Before recommending, read the active slice above. Active cards are claimed soft locks; avoid recommending the same card or adjacent/conflicting work unless the user explicitly asks to continue that active card.

User argument: $ARGUMENTS — if non-empty (a title or area like an area tag or path prefix), narrow the queue. If empty, scan the full ready slice (--ready keeps cards with open advances prereqs — they are pullable with an "awaiting: (you may start)" advisory line, since advances is a soft "should precede" not a hard start-gate; hard waits are expressed via waiting_on / waiting_until).

Selection criteria

goc lists open cards sorted by value desc then created asc. The top entry is the auto-pick candidate, subject to the autonomy gate below.

Contribution ladder

high outranks medium outranks low. Tags refine:

• contribution: high — wrong algorithm vs. cited literature, silent state corruption, broken public API, default config that contradicts the science. Doc claims that contradict an authoritative source — tags: [documentation] + contribution: high is the high-impact doc-quality slot. Treat these as load-bearing.
• contribution: medium — tolerance creep, vacuous assertions, tests that pass for the wrong reason, missing guard rails.
• contribution: low — README pinned-metric stale, docstring documents removed flag, stale references.

Effort / independence / reversibility

• Effort — files touched, area of the project (library code vs application code, test coverage required). Library default changes carry higher cost.
• Independence — fixes whose effect can be verified without first fixing another card ship before the dependent ones. Read the body's "Why it matters" notes and any advanced_by: chain.
• Reversibility — prefer fixes with low blast radius. Local demo edits before library changes.

Autonomy gate (the human_gate field)

Every card carries human_gate: none | decision | session:

• none — autonomous-loop-safe; cron may auto-pick.
• decision — needs ONE human go/no-go before work proceeds. The body MUST already carry the framing in a ## Decision required section (per Skill(card-schema)). The human resolves asynchronously.
• session — needs interactive working session. Research-impacting framework derivations, open architectural choices.

Pickability rule (uniform across cron, /loop, explicit-by-title):

• none → recommend.
• decision → DO NOT recommend. End the session cleanly with a one-line summary pointing at the parked card and (if available) its body's ## Decision required recommendation line. Do not pause an idle agent. No commits, no half-step writes — control returns to the human at their convenience.
• session → refuse to auto-pick under autonomous mode; ask for explicit confirmation under interactive mode that "yes, this is the working session for this topic." On no/silence, end like decision.

Autonomous-mode rule (/loop, cron, or any non-interactive invocation): walk down --ready and recommend the top. If every ready candidate is decision or session, the run halts with a one-line summary listing the parked cards. Better to ship nothing than to land a research move without a review checkpoint.

Explicit invocation by title: read the named card via goc show <title> and check the gate. Apply the rules above on the specific card.

Reclassify after reading

The human_gate is a hypothesis from the filing round; the body often reveals the real shape. Before recommending work, re-check whether the fix would:

• Close (or reopen) a gap in docs/framework/*.md.
• Pick one of two literature-backed mechanism candidates.
• Set a sign / direction convention.
• Introduce a new named primitive.
• Flip a default whose rationale is documented against a paper or axiom.
• Update an empirical / publication-tier claim.

If any apply, the gate should be at least decision (likely session). Recommend escalation via Skill(advance-card) to fix the gate, not working it autonomously. The right move is a 2-line edit to the frontmatter + (if upgrading to decision) writing the ## Decision required section in the body — then the run ends and the human comes back.

Output

A single recommendation with:

• Slug + one-line subject of the recommended card.
• 2-line rationale — contribution, why it's the highest-leverage open pick, any advanced_by edges that matter.
• Next-step pointer: typically "Run Skill(advance-card) <title> active to claim, then work it." If gated decision or session, point at the parked framing and end.

The output is a recommendation, not a plan. The user (or /loop) picks whether to actually run Skill(advance-card) next.
