+# 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).
+
+## Related issues
+
+- #96: Architect agent parent issue
+- #100: Architect formula — research + design fork identification

+- PR has question comments (Q1, Q2, Q3... format)

+     - Acceptance criteria (max 5)
+     - Dependencies
+   - File via Forgejo API on the **disinto repo** (not ops repo)
