#
# This formula orchestrates the architect agent's workflow:
#   Step 1: Preflight — validate prerequisites and identify target issue
#   Step 2: Research + pitch — analyze codebase and write sprint pitch
#   Step 3: Sprint PR creation with questions (issue #101)
#   Step 4: Answer parsing + sub-issue filing (issue #102)

# AGENTS.md maintenance is handled by the gardener (#246).

description = """
This step performs preflight checks and identifies the most unblocking vision issue.

Actions:
1. Pull latest code from both disinto repo and ops repo
2. Read prerequisite tree from $OPS_REPO_ROOT/prerequisites.md
3. Fetch open issues labeled 'vision' from Forgejo API
4. Check for open architect PRs on ops repo (handled by #101/#102)
5. If open architect PRs exist, handle accept/reject responses (see Capability B below)
6. If no vision issues, signal PHASE:done

Skip conditions:
- If no vision issues are found, signal PHASE:done

Output:
- Sets ARCHITECT_TARGET_ISSUE to the issue number of the selected vision issue
- Exports VISION_ISSUES as a JSON array of issue objects

## Capability B: Handle accept/reject on existing pitch PRs

When open architect PRs exist on the ops repo:

1. Fetch comments on each open architect PR via Forgejo API
2. Look for human response:

   **ACCEPT** (case insensitive): Human wants to proceed
   - Architect does deep research for design forks (same as #100 research but now identifying decision points)
   - Formulates multiple-choice questions (Q1, Q2, Q3...)
   - Updates the sprint spec file on the PR branch:
     - Adds `## Design forks` section with fork options
     - Adds `## Proposed sub-issues` section with concrete issues per fork path
   - Comments on the PR with the questions formatted as multiple choice
   - Signal PHASE:done (answer processing is #102)

   **REJECT: <reason>** (case insensitive, reason after colon):
   - Journal the rejection reason via profile_write_journal (if .profile exists)
     — the architect learns what pitches fail
   - Close the PR via Forgejo API (do not merge — rejected pitches do not persist in sprints/)
   - Remove the branch via Forgejo API
   - Signal PHASE:done

   **No response yet**: skip silently, signal PHASE:done

All git operations use the Forgejo API (create branch, write/update file, create PR,
close PR, delete branch). No SSH.

id    = "research_pitch"
title = "Research + pitch: analyze codebase and write sprint pitch"
description = """
This step performs deep codebase research and writes a sprint pitch for the
selected vision issue.

Actions:

1. Read the codebase deeply:
   - Read all files mentioned in the issue body
   - Search for existing interfaces that could be reused
   - Check what infrastructure already exists

2. Assess complexity and cost:
   - How many files/subsystems are touched?
   - What new infrastructure would need to be maintained after this sprint?
   - What are the risks (breaking changes, security implications, integration complexity)?
   - Is this mostly gluecode or greenfield?

3. Write sprint pitch to scratch file for PR creation step (#101):

# Sprint pitch: <name>

## Vision issues
- #N — <title>

## What this enables
<what the project can do after this sprint that it can't do now>

## What exists today
<current state — infrastructure, interfaces, code that can be reused>

## Complexity
<number of files, subsystems, estimated sub-issues>
<gluecode vs greenfield ratio>

## Risks
<what could go wrong, what breaks if this is done badly>

## Cost — new infra to maintain
<what ongoing maintenance burden does this sprint add>
<new services, cron jobs, formulas, agent roles>

## Recommendation
<architect's assessment: worth it / defer / alternative approach>

IMPORTANT: Do NOT include design forks or questions yet. The pitch is a go/no-go
decision for the human. Questions come only after acceptance.

Output:
- Writes sprint pitch to $SCRATCH_FILE (/tmp/architect-{project}-scratch.md)
- The pitch serves as input for sprint PR creation step (#101)

id    = "sprint_pr_creation"
title = "Sprint PR creation with questions (issue #101)"
description = """
This step creates a PR on the ops repo with the sprint proposal when no PR exists yet.

## Capability A: Create pitch PR (from research output)

If step 2 (research/pitch) produced a pitch and no PR exists yet:

1. Create branch `architect/<sprint-slug>` on ops repo via Forgejo API
   - Sprint slug: lowercase, hyphenated version of sprint name
   - Use Forgejo API: POST /repos/{owner}/{repo}/git/branches

2. Write sprint spec file to sprints/<sprint-slug>.md on the new branch:

# Sprint: <name>

## Vision issues
- #N — <title>

## What this enables
<what the project can do after this sprint that it can't do now>

## What exists today
<current state — infrastructure, interfaces, code that can be reused>

## Complexity
<number of files/subsystems, estimated sub-issues>
<gluecode vs greenfield ratio>

## Risks
<what could go wrong, what breaks if this is done badly>

## Cost — new infra to maintain
<what ongoing maintenance burden does this sprint add>
<new services, cron jobs, formulas, agent roles>

## Recommendation
<architect's assessment: worth it / defer / alternative approach>

3. Create PR on ops repo via Forgejo API:
   - Title: `architect: <sprint summary>`
   - Body: pitch content (what it enables, complexity, risks, cost)
   - Base branch: primary branch (main/master)
   - Head branch: architect/<sprint-slug>
   - Footer: "Reply `ACCEPT` to proceed with design questions, or `REJECT: <reason>` to decline."

4. Signal PHASE:done

## Forgejo API Reference

All operations use the Forgejo API with `Authorization: token ${FORGE_TOKEN}` header.

### Create branch
```
POST /repos/{owner}/{repo}/branches
Body: {"new_branch_name": "architect/<sprint-slug>", "old_branch_name": "main"}
```

### Create/update file

```

### Create PR
```
POST /repos/{owner}/{repo}/pulls
Body: {"title": "architect: <sprint summary>", "body": "<pitch-content>", "head": "architect/<sprint-slug>", "base": "main"}
```

### Close PR

id    = "answer_parsing"
title = "Answer parsing + sub-issue filing (issue #102)"
description = """
This step processes human answers to design questions and files sub-issues.

## Preflight: Detect PRs in question phase

An architect PR is in the question phase if ALL of the following are true:
- PR is open
- PR body or sprint spec file contains a `## Design forks` section (added by #101 after ACCEPT)
- PR has question comments (Q1, Q2, Q3... format)

## Answer parsing

Human comments on the PR use this format:
```
Q1: A
Q2: B
Q3: A
```

Parser matches lines starting with `Q` + digit(s) + `:` + space + letter A-D (case insensitive).
Ignore other content in the comment.

## Processing paths

### All questions answered (every `### Q` heading has a matching `Q<N>: <letter>` comment)

1. Parse each answer (e.g. `Q1: A`, `Q2: C`)
2. Read the sprint spec from the PR branch
3. Generate final sub-issues based on answers:
   - Each sub-issue uses the appropriate issue template (bug/feature/refactor from `.codeberg/ISSUE_TEMPLATE/`)
   - Fill all template fields:
     - Problem/motivation (feature) or What's broken (bug/refactor)
     - Proposed solution (feature) or Approach (refactor) or Steps to reproduce (bug)
     - Affected files (max 3)
     - Acceptance criteria (max 5)
     - Dependencies
   - File via Forgejo API on the **disinto repo** (not ops repo)
   - Label as `backlog`
4. Comment on PR: "Sprint filed: #N, #N, #N"
5. Merge the PR (sprint spec with answers persists in `ops/sprints/`)

### Some questions answered, not all

1. Acknowledge answers received
2. Comment listing remaining unanswered questions
3. Signal PHASE:done (check again next poll)

### No answers yet (questions posted but human hasn't responded)

1. Skip — signal PHASE:done
