About this skill

AI-consumed reference. Optimized for Claude to read during execution. Human-readable explanation: see docs/architecture/HIERARCHICAL_PLANNING.md or docs/getting-started/ depending on topic.

Plan Orchestrator

Single entry point for the 11-verb hierarchical-planning vocabulary. Routes user intent → backing script in aura-frog/scripts/plans/. Replaces 10 separate command files with one consolidated dispatcher.

Owner command: commands/plan.md (single user-facing command) Bare-word router: hooks/bare-word-router.cjs (active-plan vocabulary) Data model: .claude/plans/ per Tech Spec §6

verb_table[11]

verbs[11]{verb,tier_in,tier_out,script,mutates_active_json}:
  bootstrap,—,T0+T1+T2,new-plan.sh,true
  expand,T1/T2/T3,T2/T3/T4,expand-node.sh,false
  next,T3,T4,next-task.sh,true
  status,—,—,render-plan-tree.sh,false
  replan,T1-T4,T1-T4,replan-node.sh,false
  promote,T4,T1/T2,promote-node.sh,false
  archive,T2+,T2+,archive-feature.sh,false
  undo,T1-T4,T1-T4,undo-decision.sh,true
  freeze,T1-T4,T1-T4,freeze-branch.sh,false
  thaw,T1-T4,T1-T4,thaw-branch.sh,false
  conflicts,—,—,conflicts-scan.sh,false

bootstrap is the unprefixed /aura-frog:plan (no verb) — T0/T1/T2 interview. Every other verb requires an explicit target node ID or option flags.

intent_keywords[11]

Used by Stage 2 of the routing pipeline when the user's input has no explicit verb prefix. Match by stemmed substring (case-insensitive).

keywords[11]{verb,phrases}:
  bootstrap,"plan|bootstrap|set up the plan|init plan|new plan"
  expand,"expand|decompose|break down|drill down|split into stories|split into tasks"
  next,"next|next task|what's next|claim next|dispatch next|pick up"
  status,"status|tree|render|show plan|where are we|progress"
  replan,"replan|rework|reset|redo plan|discard plan|change plan"
  promote,"promote|surface|bubble up|elevate|discovery|insight up"
  archive,"archive|compress|wrap up|finalize feature|close out"
  undo,"undo|rollback|revert|restore|step back"
  freeze,"freeze|pause|halt|park|block|stop work on"
  thaw,"thaw|unfreeze|resume|continue|unblock"
  conflicts,"conflict|collision|overlap|incompatible|conflicts list|conflict check"

A user utterance like "let's expand FEAT-A into stories" matches expand via expand|decompose. "rollback" matches undo. "what's next" matches next.

3-stage routing pipeline

When invoked (via /aura-frog:plan <input> or bare-word router), execute in order — stop at the first stage that produces a single match.

Stage 1 — Explicit verb prefix (deterministic)

Pattern: <verb> [<target_id_or_flags>] where <verb> ∈ verb_table.

Examples:

  • expand FEAT-A → run expand-node.sh FEAT-A
  • next → run next-task.sh
  • freeze TASK-00042 --reason "blocked on db schema" → run freeze-branch.sh TASK-00042 --reason "..."
  • conflicts list --open → run conflicts-scan.sh list --open

If the first token matches a verb in verb_table → dispatch directly. Skip Stage 2/3.

Legacy command shape support: If invoked via a plan-<verb>.md alias stub (e.g. /aura-frog:plan-expand FEAT-A), treat as Stage 1 with the verb implied — the stub file passes the verb explicitly.

Stage 2 — Intent classification (keyword match)

If Stage 1 doesn't match, scan input against intent_keywords. Match each keyword group; collect verbs whose phrases appear in the input.

  • Single match → run resolve-node.sh against any node-shaped token (matches ^(MISSION|INIT|FEAT|STORY|TASK)-[A-Z0-9]+$ OR title substring), then dispatch the matched verb.
  • Multi-match (e.g. "expand and replan FEAT-A" hits both expand + replan) → surface to user: Two intents detected: expand, replan. Run one at a time — which first?
  • Zero matches → fall through to Stage 3.

Stage 3 — LLM fallback (ambiguous)

No explicit verb, no keyword match. Surface a structured prompt:

Couldn't auto-route this. The plan vocabulary is: bootstrap, expand, next, status,
replan, promote, archive, undo, freeze, thaw, conflicts. Closest matches: <top 2 by
edit distance>. Reply with a verb or `/aura-frog:plan status` to see the tree.

Do not guess. Do not auto-dispatch in Stage 3.

Node resolution

When a verb takes a <target> arg, the target may be:

  1. Full ID (FEAT-A, TASK-00042) — exact match required.
  2. Title substring (auth-flow) — case-insensitive substring of the node's intent: frontmatter field.
  3. Special tokens — --active resolves to active.task from active.json. --feature resolves to active.feature.

Delegate to scripts/plans/resolve-node.sh <input> — exit 0 single match, 1 multi-match (print candidates), 2 no match.

Atomicity contract (applies to every mutating verb)

Every backing script that writes a node file must:

  1. Read the current .claude/plans/active.json and target node file.
  2. Save checkpoint to .claude/plans/checkpoints/<NODE_ID>.<ISO8601>.json containing pre-mutation state + git SHA.
  3. Mutate the target file with revision += 1.
  4. Validate via bash scripts/plans/validate-plan-tree.sh — abort + restore checkpoint if any invariant fails.
  5. Append history.jsonl decision event: {ts, verb, target, before_revision, after_revision, agent}.
  6. Atomic write — write to <file>.tmp, then mv over the target. Never partial-write a node file.

Backing scripts

Script Owner verb Purpose
new-plan.sh bootstrap Init .claude/plans/ skeleton (existing, idempotent)
expand-node.sh expand Decompose T2→T3 or T3→T4. Dispatches feature-architect or story-planner agent.
next-task.sh next Dispatch next ready T4 — reads graph-index.json when the project has a fresh one, else rescans the active T3's task files. --rebuild regenerates the index.
freeze-branch.sh freeze Cascade-freeze descendants. Save checkpoint, refuse on done/archived.
thaw-branch.sh thaw Reverse freeze. Validate blocker resolved + git-diff compatibility per §21.6.
archive-feature.sh archive Compress completed T2 to summary + move originals to archive/.
conflicts-scan.sh conflicts Wrap L1+L2 detection (conflict-detector hook). List/show/resolve/history/check.
replan-node.sh replan Mutate target + descendants. Budget-aware (refuse if replan_count >= replan_budget).
promote-node.sh promote Bubble T4 discovery up to T2/T1 — append to discoveries[], increment revision.
undo-decision.sh undo Restore latest .claude/plans/checkpoints/<id>.*.json (LIFO).
resolve-node.sh (helper) Resolve <input> to node ID. Exit 0/1/2.

Existing: new-plan.sh, validate-plan-tree.sh, render-plan-tree.sh. All others new in v3.7.2.

graph-index.json — the adjacency cache

<plans_dir>/graph-index.json holds one record per node (tier, status, parent, children, depends_on, path, intent), so the questions asked on every dispatch and every render — who is my parent, which tasks under this story are ready — do not require re-walking the tree and re-parsing frontmatter out of every .md. Built and maintained by hooks/lib/vault-index.cjs.

graph_index[5]{aspect,behaviour}:
  Opt-in,"Nothing creates it implicitly. `next-task.sh --rebuild`, `render-plan-tree.sh --rebuild` or `validate-plan-tree.sh --rebuild` writes it the first time."
  Maintained,"`_lib.sh#set_field` patches the affected entry after each mutation — one file read, not a rescan. No-op when the index does not exist."
  Self-healing,"Readers reject it when a node file is missing, newer than the index, or any directory changed since the build (which is how a newly created task is caught), and fall back to their own scan."
  Authority,"The .md files are the source of truth. validate-plan-tree.sh never READS the index — it PRODUCES one, and only from a tree whose invariants passed."
  Disable,AF_GRAPH_INDEX_DISABLED=true

The index can only ever cost time, never accuracy: every consumer keeps the filesystem scan as its fallback, and takes it whenever the index is absent, stale or disabled.

Bare-word activation

When .claude/plans/active.json exists, the user may type a verb as the first token of a short message and have it route here. hooks/bare-word-router.cjs handles detection; this skill receives the routing hint and dispatches per Stage 1.

Activation conditions (all must hold):

  • .claude/plans/active.json is present and parseable.
  • First token of the user prompt is a member of verb_table[].verb.
  • Total word count ≤ 5 (so "next" routes but "next steps are unclear" doesn't).

When a verb requires a target but none is given, suggest the most likely:

  • next → run; needs nothing.
  • expand → suggest active.feature or active.story.
  • freeze/thaw/replan/promote/undo → suggest active.task if set.

Override prefixes

User can bypass the router and force a verb:

  • must do: <verb> <args> → Stage 1 only; never fall through.
  • just do: <verb> <args> → same.
  • exactly: <verb> <args> → same.

These prefixes also bypass any confirmation prompts in the backing scripts (treat as --force).

Disable mechanism

  • AF_PLAN_ROUTING_DISABLED=true → skill exits early, /aura-frog:plan falls back to direct script invocation per command file protocol.

Related Rules

  • rules/workflow/run-plan-bridge.md — anchor /run to active T4.
  • rules/core/plan-trust-policy.md — when memory vs plan tree conflict, prefer plan.
  • rules/workflow/checkpoint-discipline.md — checkpoint format + when required.
