/archcore:plan

Plan future work from the project context. Context resolution (skills/_shared/gate-contract.md, section Context resolution) records the claims, unknowns, hazards, and authority; the conductor (skills/_shared/delta-routing.md) selects the documents a later reader needs; instruments produce them. Vision types are the primary output. Reads cover all three categories: vision supplies intent and resumption targets, knowledge supplies constraints, experience supplies precedent.

When to use

• "Plan a new feature for CSV export" → typically one spec and one plan
• "Upgrade the HTTP client across three services with a coordinated rollout" → a plan alone
• "Plan the notifications platform" → a prd, one spec per capability, one plan
• "Fix the typo in the onboarding copy" → no document; implement directly
• "I need market research before we plan" → acquisition instrument
• "We must trace these requirements for the auditor" → only the requirement levels that obligation names
• "Investigate X before we plan" → research; "Compare the alternatives for Y" → rnd
• "REST or a queue for SAP? Two teams disagree", with the facts of both options recorded → rfc
• research <topic> as the first word → the type research

Not plan:

• Recording a decision → /archcore:document
• Documenting existing code → /archcore:document
• Codifying a team standard → /archcore:document
• Checking documents against code → /archcore:review

Entry

Apply in this order:

Signal	Action
No arguments, one draft with a state block this command resumes	Resume it at its earliest incomplete gate
No arguments, several such drafts	Resume rule 10 in skills/_shared/gate-contract.md
No arguments, a clear request in the session or one unfinished plan	Offer a start menu of at most four items, each with the evidence that names it, the recommended item first
No arguments and no reliable signal	Ask one question — what outcome to plan; a dirty branch alone is not a target
The first word is a type slug	The explicit type request per explicit-type-request-wins.adr; a leading research requests the type research
Any other request	Context resolution, then Selection per skills/_shared/delta-routing.md
A decision surfaces at a gate	Record the adr through the decision instrument (skills/_shared/tracks/decision.md), then return to the open gate

Research boundary: discovery feeding an mrd → brd → urd requirements chain belongs to acquisition. A request naming a pending decision or a set of candidates to choose between produces rnd only when the evidence to choose is missing; any other investigation produces research. WHEN the deciding facts are already recorded and the open part is whose weights win — two owners disagree, or the owner has not chosen — the decision instrument records an rfc, and no rnd is created. A standalone external material is filed through /archcore:document. A request proposing a specific target for team review ("let's adopt Y", "draft an RFC for Y") belongs to /archcore:document's decision instrument; a lone "should we switch to Y" with the evidence to choose missing stays here as rnd.

Execution

1. Ground

Complete this step before asking the user any question. The research vocabulary probe (skills/_shared/research-compatibility.md) runs only under its own condition 1 — a request or type naming research or evidence, a selection engaging the research instrument, or a grounding result of either type. Add research and evidence to the planning-moment filter below only when the probe returns yes; a topic search without a type filter finds documents of both types on every engine. If this skill has no shell tool, use the probe result the host supplied; if none was supplied, report needs-vocabulary-probe with the helper path and stop before the first MCP call that names either type.

The actor-subject probe (skills/_shared/actor-subject-compatibility.md) runs under its own condition 1 — a request naming scenario or journey, a selection engaging the illustrate instrument, or a grounding result of either type — and adds both types to the filter below only when it returns yes. The same no-shell rule applies: report needs-vocabulary-probe and stop before the first MCP call that names either type.

1. Search .archcore/ with mcp__archcore__search_documents and mcp__archcore__list_documents across all three categories. Pass a planning-moment type filter — for example types=["idea", "prd", "plan", "spec", "rnd", "rfc", "adr", "rule", "task-type", "cpat"] — and add "scenario", "journey" when the actor-subject probe returned yes — instead of relying on the global type ranking. Do not exclude a category from reads.
2. WHEN a found document carries implements, depends_on, or related relations, pull the linked documents one hop via mcp__archcore__list_relations and mcp__archcore__get_document.
3. WHEN a found draft on the topic carries an archcore:track state block, resume it per the resume rules in skills/_shared/gate-contract.md and skills/_shared/delta-routing.md instead of opening a new track.
4. Read git state — current branch, recent commits, working tree — and the code areas the topic names. Record the concrete files and modules for Step 5, and note owner documents whose referenced paths changed after them — the staleness input to Selection.
5. IF .archcore/ exists but contains no documents, THEN proceed on outer-context grounding (git state and the codebase) and report that zero documents were found.
6. IF .archcore/ does not exist, THEN announce initialization in one line and call mcp__archcore__init_project without asking a question.

Global sources. If a list_documents / search_documents result has global: true / read_only: true / source_kind: "global", load skills/_shared/globals.md. Also load it when a search_documents response's coverage names a source other than "local" — even when results is empty: the empty page is exactly where that file's retry ladder applies. Never modify a global document and never target one with add_relation. Absent any global match, proceed as usual.

2. Select

Build the context record per skills/_shared/gate-contract.md, section Context resolution, then run Selection per skills/_shared/delta-routing.md and report its selection line. Never ask the user to choose an instrument.

3. Budget

Interview mechanics, question form, and the ceiling of 5 questions per invocation: skills/_shared/elicitation-contract.md.

4. Execute the selection

Invoke each selected instrument, in conductor order, per the instrument registry and sequencing rules in skills/_shared/delta-routing.md. Run each instrument's gates per skills/_shared/gate-contract.md: evaluate skip_when first at every gate, keep track state only in the archcore:track block inside the draft artifact (with the claims: field this command adds), persist each gate close in one mcp__archcore__update_document call, and follow the resume rules on re-entry. Gate bodies, per-gate questions, and relation wiring live in the track files — do not restate them.

Before delegating research or evidence work, pass the current vocabulary probe result and absolute plugin root to the assistant. If the assistant returns needs-vocabulary-probe, run the helper and resume the same task. Before delegating any other document write or relation work, pass the absolute plugin root to the assistant. The assistant reads skills/_shared/relation-authoring.md under that root.

5. Map tasks to files

WHEN the selection produced a plan document:

1. Annotate each task in the plan's Tasks section with the concrete files or modules that grounding surfaced for it, using @path/to/file notation, in one mcp__archcore__update_document call.
2. WHEN grounding surfaced no file or module for a task, state that no target was found for that task. Do not guess a path.
3. Confirm the plan carries its ## Declared Delta section per sequencing rule 9 of skills/_shared/delta-routing.md.

WHEN the selection produced no plan document, skip to Result — the exit gate or the selection line names the follow-ups.

6. Implement fork

WHEN a blocking exit check stopped the selection, skip this step and go to Result. Otherwise, offer exactly two exits and let the user choose:

• Implement now — start on the mapped task list, first phase first, against the files mapped in Step 5.
• Stop here — the draft documents and relations stay in .archcore/; a later /archcore:plan invocation resumes any draft that still carries a state block.

Result

Report:

• The selection line, and the inferred scope when no argument set it.
• Produced documents grouped by category — vision, knowledge, experience — with each document's path and status.
• Relations created, plus candidate mcp__archcore__add_relation targets among existing documents, or a statement that none match.
• retire claims reported for closeout discharge, when any exist.
• Next actions, naming only v2 commands: /archcore:plan to continue the selection, /archcore:document <subject> to record a decision or document code touched during implementation, /archcore:review to check the implementation against the recorded plan and reconcile its Declared Delta.
• WHEN contract drafting remains open on a material user-owned choice, name the draft spec, the unanswered choice, and the behavior it changes. Do not offer implementation until that check passes. Name the three ways to continue — answer the choice, delegate it ("you decide"), or proceed anyway — and the resume command /archcore:plan <spec title>.
• Name instruments and stages in plain words; do not print a gate address of the form <track>.<stage>.
