get_helpread-only

Forge how-to on demand (no project needed): propose→adopt, what a System is, Balance Lab formats, sign-in. Call when unsure.

get_workflowread-only

Run FIRST in a new repo (no project): first-connect routine + the working-agreement block to ADD to AGENTS.md/CLAUDE.md now (tell the user in one line; remove if they object).

import_from_coderead-only

One-command codebase import: recipe + batch id — propose one Context overview + one System per real module; the owner adopts all at once.

design_ui_from_systemsread-only

Recipe to design the UI from Systems (user request only): steps + batch id — confirm canvas aspect, then screens + PLACED elements + edges in one batch.

post_log

Append a build-log entry to Activity — what you built/decided (commit-note style).

get_project_contextread-only

FULL design dump — LARGE, last resort; prefer get_project_meta + list_*/get_*/search.

list_projectsread-only

Projects your key reaches (id, name, role); pass an id as project_id to switch.

get_project_metaread-only

START HERE. Tiny overview: counts, members, task claims + working_now (avoid collisions), forge_workflow_version.

trace_ui_from_imageread-only

SECONDARY (user-driven UI): turn a screen's REFERENCE IMAGE into placed elements. Returns the image itself plus the recipe — the canvas resolution, the fraction→pixel conversion that stops coordinates landing wrong, and what is already on the screen so a second pass updates instead of duplicating. You look at the picture and send back propose_element / update_element with x/y/w/h; it all lands in

get_staleread-only

What has drifted between the Idea lane and the System Specs — the design's own out-of-sync list, computed deterministically (no AI, no tokens). Three kinds: Idea notes edited since the systems were generated from them (with the systems each one touches), Idea notes whose prose the systems have moved past, and specs whose stamped source fingerprint no longer matches. Read this before assuming the d

resync_from_idearead-only

The recipe for re-syncing ONE changed Idea note into the specs that depend on it — the same scoped job the app's "Re-sync N systems" button does, minus the button. Returns the note, the affected specs in full, and exactly how to send the result back. You do the writing; it lands in the owner's Inbox to ADOPT. CRUCIAL: send updates with `resync:true`, or the owner adopts your fix and the design sti

get_design_documentread-only

The WHOLE design as one readable document — Vision (+ Project DNA) → every System spec → reference notes, compiled deterministically from the current design. Read this to understand a project end-to-end instead of walking list_systems → get_system N times. Returns markdown plus the project `version` it was compiled from. Long designs come back PAGED — the header says 'part N of M', call again with

set_design_overview

Write the Design Document's Overview — the human-readable page a new team member reads first. WRITES DIRECTLY (no Inbox): it is a derived, clearly-labelled AI summary, not design truth, and the owner can clear or rewrite it in one click. HARD RULES, same as the in-app button: use ONLY facts stated in the design (call get_design_document with for_summary:true first); invent no mechanics, numbers or

get_briefingread-only

ONE-CALL orientation before you build: pass `files` you're about to edit (or a `task`) → the systems that own them, each with Goal + Acceptance + build status/files/last_commit/drift + coupled_systems (code neighbors an edit may break) + pending Inbox changes + recent decisions, plus open-rejection count, who's active, `recent_changes` (what happened since you were last here — a session handoff),

get_systemread-only

ONE system's full spec (Goal/Boundary/Acceptance, markdown, sources, status) + pending Inbox changes touching it.

list_systemsread-only

All systems, compact: id, name, status, 1-line goal.

get_build_regionread-only

System→code map per built system: implementing files, status, drift flag, last_commit, and acceptance-evidence COUNTS. Mapped files gone from the repo? report_drift. Pass `system:"<name|id>"` for ONE system plus the full text of its acceptance criteria (omitted from the map — it is the bulk of the payload). Big projects come back paged: the body says 'page N of M', call again with `page: N+1`.

report_drift

Flag CODE DRIFT — mapped files no longer match the repo. Advisory; a fresh report_build_status clears it.

get_historyread-only

DESIGN MEMORY: recorded decisions/logs/rejections with who/when. Read BEFORE changing a system's direction; empty = no recorded WHY — don't invent one.

get_impactread-only

BLAST RADIUS of a system (deterministic): upstream context, siblings, dependent screens/milestones, files, code-coupled systems, pending Inbox, recent activity. Run BEFORE changing it.

get_rejectionsread-only

Owner's DECLINED list — check at session start; follow each entry's guidance, then resolve_rejection(title).

resolve_rejection

Report you REVERTED a declined change (unlocks the owner's Clear). Call after realigning the build.

list_screensread-only

All screens, compact: id, name, purpose, status.

get_screenread-only

ONE screen's layout: canvas `resolution` (use THESE px), elements x/y/w/h, links, popups. Read before editing a screen. has_reference_image:true → get_screen_image shows you the actual image.

get_screen_imageread-only

A screen's reference image (HUD background) as an actual IMAGE you can see — reads the stored file inline (signed-URL fallback past 4MB).

update_element

Move/resize/relabel an element — DIRECT, live. element_id (preferred) or screen+label; x+y also places an unplaced one.

withdraw_proposal

Remove YOUR OWN still-pending Inbox item (id from the propose response / get_inbox).

delete_entitycan modify

PROPOSE a delete → Inbox (owner adopts; nothing deleted now). id preferred or exact name; flow_edge may use from+to.

dedupecan modify

Remove duplicate-named entries (keep first) — DIRECT, destructive.

reorder

Reorder milestones / tasks / elements — DIRECT. order = ids in new order; omitted keep relative order.

list_milestonesread-only

All milestones, compact: id, name, weeks, order, done/total.

get_milestoneread-only

ONE milestone: goal, weeks, difficulty, systems, every task (id/name/done/status/effort).

list_activityread-only

Change history {who, change, entity, kind, when}, newest first; filter kind/who/query.

get_inboxread-only

PENDING Inbox (the owner's triage queue). Check BEFORE proposing — avoid duplicates. Read-only.

searchread-only

Keyword search — compact hits {kind, id, name} + snippet.

propose_system

Propose a NEW system → Inbox. spec = ## Goal / ## Boundary (Owns · Doesn't own) / ## Acceptance. Exists? use update_system. (Alias: create_proposal.)

propose_context

Propose a new/updated Idea note → Inbox. Title-match to update; send the COMPLETE revised text. Set resync:true ONLY when you rewrote the note FROM the current systems (get_stale lists notes the systems have moved past) — it stops the adopted note from immediately nagging to re-generate the systems it was just written from.

propose_dna

Propose Project DNA and/or Tech Notes → Inbox (at least one).

update_system

Propose a system UPDATE → Inbox diff. get_system first; send the FULL revised spec. new_title renames; context_title+context bundles the Idea update. Set resync:true ONLY when you rewrote this spec FROM its upstream Idea (see resync_from_idea) — it re-stamps the staleness signal on adopt.

get_balanceread-only

Read Balance Lab: stat tables, boards with EVALUATED values, scenarios.

propose_balance_table

Propose a stat-doc TABLE → Inbox. csv (header; `key%` = percent; first column = name) OR schema+rows. Adopting REPLACES same-named.

propose_balance_board

Propose a node board → Inbox. Kinds const|formula|item|sheet|loadout|picker|pool|process|note|frame; formulas reference blocks by NAME; omit x/y = auto-layout. Adopting REPLACES same-named.

propose_milestone

Propose a NEW milestone (+ optional tasks) → Inbox.

report_milestone_progress

Mark existing-milestone tasks done → Inbox progress card (owner adopts the ticks).

report_build_status

Report a SYSTEM's status (todo|in-progress|implemented) — DIRECT, live. ALWAYS pass files (full list — it REPLACES); non-todo with no files shows done-but-EMPTY. 'implemented' counts as VERIFIED only when every UNIT-TESTABLE ## Acceptance bullet is backed via evidence[{criterion,proof}]; a bullet tagged [manual]/[e2e]/[ui]/[wip] is EXEMPT (verified by manual/e2e). Otherwise it's a CLAIM (verified:

propose_flow_edge

SECONDARY (user-driven UI): propose a link between two existing screens → Inbox.

propose_element

SECONDARY (user-driven UI): propose an element onto a screen → Inbox. ALWAYS pass x/y/w/h (px on the screen's `resolution` from get_screen); no coords = unplaced pile.

propose_screen

SECONDARY (user-driven UI): propose a NEW screen → Inbox. parent = popup over that screen; purpose grounds AI suggestions. Whole UI? design_ui_from_systems first.

report_screen_status

Report a SCREEN's status (todo|in-progress|implemented) → Inbox.

rename_screen

Rename a screen IN PLACE — DIRECT; links/elements follow (id-referenced).

update_milestone

Edit milestone goal/weeks/difficulty/name — DIRECT. new_name renames (never delete+recreate).

add_task

Add a task to a milestone — DIRECT. assignee:"me" claims on creation.

next_task

DISPATCHER (multi-agent): atomically pick + claim the next task to build — walks milestones in order, skips human-only tasks and any task whose systems share code files with a task another agent already holds or is actively touching, so parallel agents spread out instead of colliding. Returns the claimed task + systems, or why none is free. dry_run:true peeks without claiming.

update_task

Edit a task or CLAIM it — DIRECT. assignee:"me"+status:"in-progress" claims (errors if held; force:true for stale); done:true or assignee:"" releases.
