Raw Blame History

CascadingDev Automation System

Overview

The CascadingDev automation system processes discussion files during git commits to maintain structured summaries. It operates in two phases:

Phase 1 (Basic): Always runs, no dependencies

Parses VOTE: lines from discussions
Tracks latest vote per participant
Updates summary .sum.md files automatically

Phase 2 (AI-Enhanced): Optional, requires Claude API

Extracts questions, action items, and decisions using AI
Tracks @mentions and awaiting replies
Processes only incremental changes (git diff)
Maintains timeline and structured summaries

Architecture

automation/
├── workflow.py      # Main orchestrator, called by pre-commit hook
├── agents.py        # Claude-powered extraction agents
├── summary.py       # Summary file formatter and updater
└── __init__.py

Phase 1: Vote Tracking (Always Enabled)

How It Works

Pre-commit hook triggers automation/workflow.py --status
Finds all staged .discussion.md files
Parses entire file for VOTE: lines
Maintains latest vote per participant
Updates corresponding .sum.md file's VOTES section
Auto-stages updated summaries

Vote Format

- ParticipantName: Any comment text. VOTE: READY|CHANGES|REJECT

Rules:

Only the latest vote per participant counts
Case-insensitive vote tokens (vote:, VOTE:, Vote:)
Three valid values: READY, CHANGES, REJECT
Must follow participant bullet format: - Name: ...

Example

Discussion file:

- Alice: I like this approach. VOTE: READY
- Bob: We need tests first. VOTE: CHANGES
- Alice: Good point, updated the plan. VOTE: CHANGES

Resulting summary:

<!-- SUMMARY:VOTES START -->
## Votes (latest per participant)
READY: 0 • CHANGES: 2 • REJECT: 0
- Alice: CHANGES
- Bob: CHANGES
<!-- SUMMARY:VOTES END -->

Phase 2: AI-Enhanced Processing (Optional)

Requirements

Phase 2 supports multiple AI providers with automatic fallback chains and intelligent model selection. Configuration is managed through config/ai.yml (copied into every generated project).

Configuration: config/ai.yml (Primary Method)

Edit the configuration file to set your preferred AI providers and fallback chain:

# config/ai.yml
runner:
  # Default command chain (balanced speed/quality)
  command_chain:
    - "claude -p"
    - "codex --model gpt-5"
    - "gemini --model gemini-2.5-flash"

  # Fast command chain (simple tasks: vote counting, gate checks)
  # Used when model_hint: fast in .ai-rules.yml
  command_chain_fast:
    - "claude -p"                      # Auto-selects Haiku via subagent
    - "codex --model gpt-5-mini"
    - "gemini --model gemini-2.5-flash"

  # Quality command chain (complex tasks: design, implementation planning)
  # Used when model_hint: quality in .ai-rules.yml
  command_chain_quality:
    - "claude -p"                      # Auto-selects Sonnet via subagent
    - "codex --model o3"
    - "gemini --model gemini-2.5-pro"

  sentinel: "CASCADINGDEV_NO_CHANGES"

How it works:

The automation runner (patcher.py) iterates through the command_chain from top to bottom.
It attempts to generate a patch or summary with the first provider.
If the provider fails (e.g., API error, invalid output), it automatically retries with the next provider in the chain.
This continues until a provider succeeds or the chain is exhausted.
This resilience ensures that the automation can proceed even if one AI provider is temporarily unavailable or performs poorly on a given task.
.ai-rules.yml can specify model_hint: fast or model_hint: quality per rule
Fast models (Haiku, GPT-5-mini) handle simple tasks (vote counting, gate checks)
Quality models (Sonnet, O3) handle complex tasks (design discussions, planning)
This optimization reduces costs by ~70% while maintaining quality

Environment Overrides (Optional)

Temporarily override config/ai.yml for a single commit:

# Override command for this commit only
CDEV_AI_COMMAND="claude -p" git commit -m "message"

# Chain multiple providers with || delimiter
CDEV_AI_COMMAND="claude -p || codex --model gpt-5" git commit -m "message"

Environment variables take precedence but don't modify the config file.

Common non-interactive setups:

Provider	CLI Tool	Command Example	Authentication	Notes
Claude	`claude`	`claude -p`	Run `claude` and follow prompts to sign in	Supports custom subagents in `~/.claude/agents/`. Create with `./tools/setup_claude_agents.sh`. Uses Haiku (fast) or Sonnet (quality).
OpenAI	`codex`	`codex --model gpt-5`	Run `codex` and sign in with ChatGPT account	Codex CLI is OpenAI's terminal coding agent. Default model: GPT-5. Use `gpt-5-mini` for faster, cheaper responses.
Google	`gemini`	`gemini --model gemini-2.5-flash`	Run `gemini` and sign in with Google account	Free tier: 60 req/min. Use `gemini-2.5-flash` (fast) or `gemini-2.5-pro` (1M context, quality). Open source (Apache 2.0).

Recommended Setup: Use the provided setup script to create Claude subagents:

# One-time setup (creates ~/.claude/agents/cdev-patch.md and cdev-patch-quality.md)
./tools/setup_claude_agents.sh

Automated Discussion Status Promotion

A key feature of the automation system is its ability to automatically update the status of a discussion file based on participant votes. This moves a feature, design, or other discussion through its lifecycle without manual intervention.

How it works:

The workflow.py script is triggered on commit.
It scans staged discussion files for YAML front matter containing a promotion_rule.
It tallies VOTE: READY and VOTE: REJECT votes from eligible participants.
If the vote counts meet the configured thresholds, the script updates the status: field in the file's front matter (e.g., from OPEN to READY_FOR_DESIGN).
The updated discussion file is automatically staged.

Configuration (in discussion file front matter):

The entire process is controlled by a promotion_rule block within the YAML front matter of a discussion file (e.g., feature.discussion.md).

---
type: feature-discussion
stage: feature
status: OPEN
promotion_rule:
  allow_agent_votes: false
  ready_min_eligible_votes: 2
  reject_min_eligible_votes: 1
  ready_status: "READY_FOR_DESIGN"
  reject_status: "FEATURE_REJECTED"
---

Alice: Looks good. VOTE: READY
Bob: I agree. VOTE: READY

Parameters:

allow_agent_votes (boolean, optional): If true, votes from participants named AI_* will be counted. Defaults to false.
ready_min_eligible_votes (integer | "all", optional): The number of READY votes required to promote the status. Can be an integer or the string "all" (requiring all eligible voters to vote READY). Defaults to 2.
reject_min_eligible_votes (integer | "all", optional): The number of REJECT votes required to reject the discussion. Defaults to 1.
ready_status (string, optional): The target status to set when the ready threshold is met. Defaults to stage-specific values (e.g., READY_FOR_DESIGN for the feature stage).
reject_status (string, optional): The target status to set when the reject threshold is met. Defaults to stage-specific values (e.g., FEATURE_REJECTED).

This automation turns the discussion and voting process into a state machine, enabling a self-driving project workflow.

This creates two subagent files:

cdev-patch.md - Uses Haiku model (fast, cost-efficient) - auto-selected when TASK COMPLEXITY: FAST
cdev-patch-quality.md - Uses Sonnet model (higher quality) - auto-selected when TASK COMPLEXITY: QUALITY

The claude -p command automatically selects the appropriate subagent based on the TASK COMPLEXITY hint in the prompt:

Simple tasks (vote counting, gate checks) → command_chain_fast → Haiku
Complex tasks (design, implementation planning) → command_chain_quality → Sonnet
Default tasks → command_chain → auto-select based on complexity

Option 2: Direct API (Alternative)

pip install anthropic
export ANTHROPIC_API_KEY="sk-ant-..."

If no AI provider is configured or responding, Phase 2 features are silently skipped and only Phase 1 (votes) runs.

Features

1. @Mention Tracking

Extracts @Name and @all mentions from discussions to track who's waiting for replies.

Format:

- Alice: @Bob what do you think about OAuth2?
- Carol: @all please review by Friday

Summary section:

<!-- SUMMARY:AWAITING START -->
## Awaiting Replies

### @Bob
- @Alice: What do you think about OAuth2?

### @all
- @Carol: Please review by Friday
<!-- SUMMARY:AWAITING END -->

2. Question Tracking

Identifies questions and tracks their answers.

Markers (optional but recommended):

- Alice: Q: Should we use OAuth2 or JWT?
- Bob: A: I'd recommend OAuth2 for third-party auth.

Also detects:

Lines ending with ?
Question: prefix
Re: replies (indicate partial answers)

Summary section:

<!-- SUMMARY:OPEN_QUESTIONS START -->
## Open Questions
- @Alice: Should we cache API responses?

### Partially Answered:
- @Bob: What about rate limiting?

<!-- SUMMARY:OPEN_QUESTIONS END -->

3. Action Item Management

Tracks tasks from creation → assignment → completion.

Markers (optional but recommended):

- Alice: TODO: Research OAuth2 libraries
- Bob: I'll handle the JWT implementation.
- Alice: DONE: Completed library research, recommending authlib.
- Dave: ACTION: Review security implications

Summary section:

<!-- SUMMARY:ACTION_ITEMS START -->
## Action Items

## Decisions (ADR-style)

### Decision 1: Use OAuth2 + JWT hybrid approach
- **Proposed by:** @Alice
- **Supported by:** @Bob, @Carol
- **Rationale:** OAuth2 for robust third-party auth, JWT for stateless sessions
- **Alternatives considered:**
  - Pure JWT authentication
  - Session-based auth with cookies
<!-- SUMMARY:DECISIONS END -->

Conversation Guidelines

Natural Conversation (Recommended)

Write naturally - AI normalization extracts markers automatically:

# Examples of natural conversation that AI understands:

- Alice: I think we should use OAuth2. Does anyone know if we need OAuth 2.1 specifically?
  VOTE: READY

- Bob: Good question Alice. I'm making a decision here - we'll use OAuth 2.0 for now.
  @Carol can you research migration paths to 2.1? VOTE: CHANGES

- Carol: I've completed the OAuth research. We can upgrade later without breaking changes.
  VOTE: READY

AI normalization (via agents.py) extracts:

Decisions from natural language ("I'm making a decision here - ...")
Questions from conversational text ("Does anyone know if...")
Action items with @mentions ("@Carol can you research...")
Votes (always tracked: VOTE: READY|CHANGES|REJECT)

Explicit Markers (Fallback)

If AI is unavailable, these explicit line-start markers work as fallback:

# Markers (✅ = works without AI as simple fallback)

QUESTION: <question>   # ✅ Explicit question marker
Q: <question>          # ✅ Short form

TODO: <action>         # ✅ New unassigned task
ACTION: <action>       # ✅ Task with implied ownership
ASSIGNED: <task> @name # ✅ Claimed task
DONE: <completion>     # ✅ Mark task complete

DECISION: <choice>     # ✅ Architectural decision

VOTE: READY|CHANGES|REJECT  # ✅ ALWAYS tracked (with or without AI)

@Name                  # ✅ Mention extraction (simple regex)

Example with explicit markers:

- Alice: QUESTION: Should we support OAuth2?
- Bob: TODO: Research OAuth2 libraries
- Bob: ASSIGNED: OAuth2 library research
- Carol: DECISION: Use OAuth2 for authentication
- Dave: @all Please review. VOTE: READY

Two-Tier Architecture

AI Normalization (Primary): Handles natural conversation, embedded markers, context understanding
Simple Fallback: Handles explicit line-start markers when AI unavailable

Benefits:

✅ Participants write naturally without strict formatting
✅ Resilient (multi-provider fallback: claude → codex → gemini)
✅ Works offline/API-down with explicit markers
✅ Cost-effective (uses fast models for extraction)

Implementation Details

Incremental Processing

The system only processes new content added since the last commit:

Uses git diff HEAD <file> to get changes
Extracts only lines starting with + (added lines)
Feeds incremental content to AI agents
Updates summary sections non-destructively

Participant Agent Scripts

Before any output writers run, the runner checks the matched rule for a participants list. Each entry is a Python script path that will be executed with the staged file:

rules:
  feature_discussion_update:
    participants:
      - path: "agents/moderator.py"
      - path: "agents/visualizer.py"
        background: true
    outputs:
      self_append:
        path: "{path}"
        output_type: "feature_discussion_writer"

Key points:

Agent scripts live under agents/ and reuse the shared SDK in src/cascadingdev/agent/.
AgentContext exposes helpers like read_text() and append_block() to work safely against the repo root.
ProviderClient calls the configured AI chain (Claude → Codex → Gemini) and can return free-form or JSON responses.
The included moderator agent appends a single guided comment per commit, guarded by  to remain idempotent.
The visualizer agent watches for @AI_visual mentions, generates PlantUML diagrams, and links them back to the discussion.
Add background: true for tool-style agents (researcher, visualizer) so the runner launches them asynchronously; their follow-up work lands in the working tree after the commit and can be included in the next commit. These service agents provide information only and intentionally omit VOTE: lines to avoid influencing promotion thresholds.

Adding new personas is as simple as dropping a script into agents/ and registering it in .ai-rules.yml.

Marker Block System

Summary files use HTML comment markers for non-destructive updates. In addition to the content sections, a special state marker is used to persist structured data across runs.

Persistent Summary State

To enable robust, incremental updates, the system stores the aggregated state of questions, action items, decisions, and mentions in a JSON blob within a comment at the top of the summary file.

<!-- SUMMARY:STATE {"action_items": [...], "decisions": [...], "mentions": [...], "questions": [...]} -->

How it works:

Before processing new discussion content, the summary.py script reads this state blob from the .sum.md file.
New items extracted from the latest discussion changes are merged with the existing state.
This merging logic deduplicates items and updates their status (e.g., a question moving from OPEN to ANSWERED).
The updated state is written back to the marker.
The visible summary sections (like OPEN_QUESTIONS) are then regenerated from this canonical state.

This approach prevents information loss and ensures that the summary accurately reflects the cumulative history of the discussion, even as the discussion file itself grows.

Content Sections

<!-- SUMMARY:SECTION_NAME START -->
## Section Header
<content>
<!-- SUMMARY:SECTION_NAME END -->

Sections:

VOTES - Vote counts and participants
DECISIONS - ADR-style decisions
OPEN_QUESTIONS - Unanswered questions
AWAITING - Unresolved @mentions
ACTION_ITEMS - TODO → ASSIGNED → DONE
TIMELINE - Chronological updates (future)
LINKS - Related PRs/commits (future)

Implementation Stage Enhancements

Checkbox items in implementation.discussion.md are parsed and normalised into implementation/tasks.md and the summary's Tasks block.
Promotion to testing now checks two conditions before updating YAML frontmatter:
1. All detected checkboxes are [x].
2. At least one human participant has a VOTE: READY.
These safeguards run even when AI providers fail, ensuring the stage cannot advance on agent votes alone or with unfinished work.

Error Handling

The workflow is non-blocking:

Always exits 0 (never blocks commits)
Prints warnings to stderr for missing dependencies
Falls back to Phase 1 (votes only) if API key missing
Continues on individual agent failures

Testing

# Run all tests
pytest tests/

# Test vote parsing
pytest tests/test_workflow.py -v

# Manual test in a project
cd /path/to/cascadingdev-project
echo "- Test: Comment with vote. VOTE: READY" >> Docs/features/test/discussions/test.discussion.md
git add Docs/features/test/discussions/test.discussion.md
git commit -m "Test workflow"  # Triggers automation

Configuration

AI Provider Options

1. Claude CLI (Default)

# No configuration needed if you have 'claude' command available
# The system defaults to: claude -p '{prompt}'

# To customize:
git config cascadingdev.aicommand "claude -p '{prompt}'"

2. Gemini CLI

git config cascadingdev.aiprovider "gemini-cli"
git config cascadingdev.aicommand "gemini '{prompt}'"

3. OpenAI Codex CLI

git config cascadingdev.aiprovider "codex-cli"
git config cascadingdev.aicommand "codex '{prompt}'"

4. Direct API (Anthropic)

pip install anthropic
export ANTHROPIC_API_KEY="sk-ant-..."
# CLI commands will fallback to API if available

5. Custom AI Command

# Use any command that reads a prompt and returns JSON
git config cascadingdev.aicommand "my-ai-tool --prompt '{prompt}' --format json"

Disabling AI Features

Simply don't configure any AI provider. The system will:

Log a warning: [agents] warning: No AI provider configured, skipping AI processing
Continue with Phase 1 (vote tracking only)
Still extract @mentions (doesn't require AI)

Future Enhancements

🚧 Phase 3 (Planned):

Timeline auto-population from git commits
Link tracking (related PRs, commits)
Multi-file decision tracking
Slack/Discord notification integration
Summary diffs between commits
Natural language summary generation

Troubleshooting

"agents module not available"

Cause: Import path issue when workflow.py runs from pre-commit hook.

Solution: Already fixed in workflow.py with dual import style:

try:
    from automation import agents
except ImportError:
    import agents  # Fallback for different execution contexts

"No AI provider configured"

Cause: No AI CLI command or API key configured.

Solution: Choose one:

# Option 1: Use Claude CLI (default)
git config cascadingdev.aicommand "claude -p '{prompt}'"

# Option 2: Use Gemini CLI
git config cascadingdev.aiprovider "gemini-cli"
git config cascadingdev.aicommand "gemini '{prompt}'"

# Option 3: Use Anthropic API
pip install anthropic
export ANTHROPIC_API_KEY="sk-ant-..."

Or accept Phase 1 only (votes only, still useful)

"AI command failed with code X"

Cause: AI CLI command returned error.

Solution:

Test command manually: claude -p "test prompt"
Check command is in PATH: which claude
Verify command syntax in config: git config cascadingdev.aicommand
Check stderr output in warning message for details

Summary sections not updating

Cause: Markers might be malformed or missing.

Solution:

Check summary file has proper markers (see "Marker Block System")
Regenerate from template if needed
File should be created automatically by pre-commit hook

Votes not being detected

Cause: Format doesn't match parser expectations.

Solution: Ensure format is:

- ParticipantName: Comment text. VOTE: READY

Common issues:

Missing - bullet
Missing : after name
Typo in vote value (must be READY, CHANGES, or REJECT)
Multiple participants on one line (not supported)
