/archcore:document

Record the present state: a technical decision, existing code, or a supplied research material. The first word of the arguments selects the mode; a gate inside the mode's track selects the document type. Write affinity: knowledge types; a filed research and the decision cascade's plan belong to vision. The standard cascade can add a cpat (experience).

Command tense: /archcore:plan declares a future canon delta, /archcore:document records the present state — including work that shipped without a plan — and /archcore:review reconciles a past declared delta. Δ vocabulary: skills/_shared/delta-routing.md.

Load skills/_shared/gate-contract.md and skills/_shared/elicitation-contract.md before executing any gate.

Modes

Mode	Track and entry	Types the entry gate selects
decision	skills/_shared/tracks/decision.md, decision.classify	adr, rfc; rule through the standard cascade; an existing rfc draft on the topic → decision.resolve, which records an adr on an accepted verdict
code	skills/_shared/tracks/describe.md, describe.read	spec, doc, guide, scenario
research	skills/_shared/tracks/research.md, research.frame	research, rnd by the closing test; one external material → evidence

A document type name is not a mode. When the subject text names a type (skills/_shared/gate-contract.md, Entry terms) that the mode's track produces, the selecting gate treats that type as settled and asks no type question: document decision rfc for gRPC reaches the RFC branch. A leading word that is not a mode is topic text and goes through classification (Step 3). No mode produces a journey; an intended user path belongs to /archcore:plan.

When to use

• "We decided to go with microservices" — settled decision
• "Record the decision to use PostgreSQL"
• "Document why we chose JWT over sessions"
• "Make this our team standard for error handling"
• "Draft an RFC for switching from REST to gRPC"
• "Should we switch to Kubernetes?" — open proposal
• "We accepted the proposal — resolve the RFC" — proposal resolution
• "Document the auth module"
• "Capture how the payment system works"
• "Create reference docs for the config system" — reference material
• "Write a guide for the release process" — how-to instructions
• document code scenario for checkout — a user flow with examples over an existing spec
• document research <report> — file a ready investigation
• document research <material> — file one external material as evidence

Not document:

• Planning a feature, an initiative, or an intended user journey → /archcore:plan
• Checking documents against code, reviewing branch changes, or docs health → /archcore:review
• First-time setup → /archcore:init

Routing table

Signal	Route
No arguments	→ git investigation of the branch changes, then one classifying question (Step 3, Unclear)
The first word is a mode — decision, code, research	→ mode entry, no routing (Step 2)
Decision signals: "we decided", "record this decision", "document why we chose X", "make it our standard", "draft an RFC", a "should we switch to Y" proposal. A bare "compare X vs Y" with no proposed target belongs to /archcore:plan's research track; a proposal to add a new capability with no named technical target ("should we add caching?") is feature framing → /archcore:plan, sdd track	→ decision track — skills/_shared/tracks/decision.md, entry at decision.classify
Resolution signals: "resolve the RFC", "we accepted the proposal", "reject the RFC" — an rfc draft exists on the topic	→ decision track — skills/_shared/tracks/decision.md, entry at decision.resolve
Code-doc signals: "document the auth module", "capture how the payment system works", reference material (registry, glossary, lookup), how-to instructions, a user flow with examples over an existing spec	→ describe track — skills/_shared/tracks/describe.md, entry at describe.read
Research-material signals: a supplied investigation report, benchmark, transcript, or vendor document to file as is	→ research track — skills/_shared/tracks/research.md, entry at research.frame
Unclear	→ git investigation, then one classifying question (Step 3)

Execution

Step 1: Ground

Apply skills/_shared/research-compatibility.md under its condition 1 — a request or type naming research or evidence, the research track, or a grounding result of either type. If this skill has no shell tool and no probe result was supplied, report needs-vocabulary-probe with the helper path and stop before the first MCP call that names either type. 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. Apply skills/_shared/actor-subject-compatibility.md under its own condition 1 — a request whose subject names scenario or journey, or a grounding result of either type. When that probe returns yes, add scenario and journey to the type filter below. On older engines, keep the legacy filter; a code request whose subject names scenario then reports the required version and exits without a write. When the probe returns yes, add research and evidence to the type filter below. On older engines, keep the legacy filter.

Search .archcore/ on the request topic across all three categories — vision, knowledge, experience. Do not exclude a category from reads. Pass a type filter matched to this command's moment (adr, rfc, spec, doc, guide, rule, plus rnd as decision evidence, and research and evidence when the probe returned yes) instead of relying on the global type ranking. When a found document carries implements, depends_on, or related relations, pull the linked documents one hop across categories. Duplicate handling lives in the tracks' check-existing gates — do not resolve duplicates here.

If .archcore/ does not exist, announce initialization in one line and call mcp__archcore__init_project without asking a question. If .archcore/ exists but contains no documents, proceed on outer-context grounding and report that zero documents were found.

Global sources. If a mcp__archcore__list_documents / mcp__archcore__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.

Step 2: Mode entry

If the first word is a mode, execute the mapped entry without routing:

• decision → decision track. An rfc draft on the topic plus resolution wording enters decision.resolve; any other request enters decision.classify, which selects adr, rfc, or the standard outcome. A type name in the subject (adr, rfc, rule) satisfies that gate's skip_when.
• code → describe track at describe.read. describe.draft selects spec, doc, guide, or scenario; a type name in the subject settles its type question. describe.read records features/*.feature files as evidence when present; a scenario with no covering spec routes to the earliest gate that produces the spec per skills/_shared/gate-contract.md.
• research → research track at research.frame; the supplied report satisfies frame inputs without an interview (investigation versus one external material: skills/_shared/gate-contract.md, Entry terms), and the closing test selects the type — a report that ends in a recommendation is an rnd, a report that covers a scope is a research. One external material with no investigation enters research.gather as standalone evidence, records the request in the evidence draft's Clarifications, and exits after gather. Follow the compatibility contract's no-write exit when the type is unsupported.

Then go to Step 4.

Step 3: Classify

Classify the target as resolution, decision, code-doc, research material, or unclear:

• Resolution — the request names a verdict on an existing open proposal (resolution signals above) and an rfc draft on the topic exists → decision track at decision.resolve. Check this before Decision: wording that also reads as a settled-decision signal ("we accepted the proposal") routes here whenever a matching rfc draft exists.
• Decision — the request records a settled choice or an open proposal (decision signals above) → decision track at decision.classify.
• Code-doc — the request describes existing code, reference material, a procedure, or a user flow over an existing spec (code-doc signals above) → describe track at describe.read.
• Research material — the request supplies a ready report or one external material to file (research-material signals above) → research track at research.frame.
• Unclear — inspect git state and the working tree first: recent commits and changed files are evidence of what the user has been working on. If the evidence still supports both readings, ask one classifying question — "Is this a decision to record or existing code to document?" — with the recommendation drawn from the git evidence.

Step 4: Execute the track

Run the selected track gate by gate per skills/_shared/gate-contract.md. The track owns check-existing, per-gate elicitation, composition, and relation wiring.

Question budget: per skills/_shared/elicitation-contract.md — auto mode draws from the shared per-invocation ceiling; a mode entry raises to the track's per-gate maxima.

Result

Report the produced documents grouped by category:

• knowledge — adr, rfc, spec, doc, guide, rule, evidence, scenario
• vision — research (scope-covering report), rnd (recommendation-closed report, or compatibility fallback), plan (architecture cascade)
• experience — cpat (standard cascade opt-in)

List each document's path and relation edges. Name tracks and steps in plain words; do not print a gate address of the form <track>.<stage>. Close with one recommended next action naming only /archcore:plan, /archcore:review, or a repeat /archcore:document invocation with its mode.
