-# Architect — Agent Instructions
-
-## What this agent is
-
-The architect is a strategic decomposition agent that breaks down vision issues
-into development sprints. It proposes sprints via PRs on the ops repo and
-converses with humans through PR comments.
-
-## Role
-
-- **Input**: Vision issues from VISION.md, prerequisite tree from ops repo
-- **Output**: Sprint proposals as PRs on the ops repo, sub-issue files
-- **Mechanism**: Formula-driven execution via `formulas/run-architect.toml`
-- **Identity**: `architect-bot` on Forgejo
-
-## Responsibilities
-
-1. **Strategic decomposition**: Break down large vision items into coherent
-   sprints that can be executed by the dev agent
-2. **Design fork identification**: When multiple implementation approaches exist,
-   identify the forks and file sub-issues for each path
-3. **Sprint PR creation**: Propose sprints as PRs on the ops repo with clear
-   acceptance criteria and dependencies
-4. **Human conversation**: Respond to PR comments, refine sprint proposals based
-   on human feedback
-5. **Sub-issue filing**: After design forks are resolved, file concrete sub-issues
-   for implementation
-
-## Formula
-
-The architect is driven by `formulas/run-architect.toml`. This formula defines
-the steps for:
-- Research: analyzing vision items and prerequisite tree
-- Design: identifying implementation approaches and forks
-- Sprint proposal: creating structured sprint PRs
-- Sub-issue filing: creating concrete implementation issues
-
-## Execution
-
-Run via `architect/architect-run.sh`, which:
-- Acquires a cron lock and checks available memory
-- Sources shared libraries (env.sh, formula-session.sh)
-- Uses FORGE_ARCHITECT_TOKEN for authentication
-- Loads the formula and builds context from VISION.md, AGENTS.md, and ops repo
-- Executes the formula via `agent_run`
-
-## Cron
-
-Suggested cron entry (every 6 hours):
-```cron
-0 */6 * * * cd /path/to/disinto && bash architect/architect-run.sh
-```
-
-## State
-
-Architect state is tracked in `state/.architect-active` (disabled by default —
-empty file not created, just document it).
