Add beads worker workflow with beads-sync branch integration and persistent credential management

[Copilot]

Beads Worker Workflow - Complete Implementation ✅

Summary

Successfully created an agentic workflow that automatically picks up and executes ready tasks from beads-equipped repositories. The workflow runs hourly and integrates with the beads task tracking system using a clean architecture with separate jobs for bead claiming and agent execution.

Implementation Checklist

• Understand beads system and workflow structure
• Create hourly scheduled workflow with beads integration
• Use schedule: hourly for cleaner configuration
• Enable strict mode with strict: true
• Use contents: read for main workflow permissions
• Add separate bead custom job with contents: write
• Add custom safe output jobs for bead state updates
• Simplify bead-update-state to automatically use claimed bead
• Add state validation with options field
• Replace full checkout with lightweight git initialization
• Use beads-sync branch for all beads operations
• Let beads handle git data synchronization
• Keep credentials throughout job for bd operations
• Add conditional execution to agent job (only runs if bead claimed)
• Add bead state machine documentation as XML comment
• Add extensive logging to all scripts
• Add release_bead job to release THE CLAIMED BEAD if still in_progress
• Use bd sync instead of manual git operations
• Test workflow compilation successfully
• Validate generated YAML structure
• Verify all components work together correctly

Technical Implementation

1. Hourly Schedule

• Uses schedule: hourly (system generates scattered cron)
• Manual trigger via workflow_dispatch for testing

2. Separate Bead Job

• Custom bead job that depends on activation
• Has contents: write permission for bead operations
• Lightweight git setup: Uses git init + remote configuration instead of full checkout
• Beads-sync branch: All operations use dedicated beads-sync branch
• Beads-managed sync: Lets beads handle git data structures via bd sync
• Persistent credentials: Credentials kept throughout job execution for all bd operations
• Finds ready beads using bd ready --json --no-daemon
• Claims first ready bead with bd update <id> --status in_progress
• Syncs changes using bd sync
• Exposes job outputs: id, title, description, status
• Extensive logging for all operations with section markers and status indicators

3. Agent Job Dependencies ✨ CONDITIONAL

• Agent job now depends on both activation and bead jobs
• Only runs if bead was claimed: if: needs.bead.outputs.id != ''
• Can reference bead information via ${{ needs.bead.outputs.id }}
• Has contents: read permission only (strict mode)
• Bead information available in prompt for context

4. Custom Safe Output: bead-update-state ✨ SIMPLIFIED & VALIDATED
Provides MCP tool for agent to update bead state with automatic bead selection and validation:

• Automatic bead selection: Always operates on the claimed bead (needs.bead.outputs.id)
• No bead_id input required: Simplified interface for ease of use
• State validation: Options field restricts state to valid values (open, in_progress, closed)
• Lightweight git setup: Uses git init with beads-sync branch
• Beads-managed sync: Lets beads handle git data via bd sync
• Persistent credentials: Credentials kept throughout job for all bd operations
• Inputs: state (required with options), reason (optional)
• States: open, in_progress, closed
• Permissions: contents: write for bead operations
• Uses bd sync to commit changes
• Extensive logging for update operations

5. Release Job
Custom job that runs with if: always() && needs.bead.outputs.id != '':

• Depends on both agent and bead jobs
• Gets the claimed bead ID from needs.bead.outputs.id
• Lightweight git setup: Uses git init with beads-sync branch
• Beads-managed sync: Lets beads handle git data via bd sync
• Persistent credentials: Credentials kept throughout job for all bd operations
• Only releases THE SPECIFIC BEAD claimed by this workflow
• Checks if that bead is still in in_progress state
• Releases it back to open state with agent result details
• Uses bd sync to commit changes
• Extensive logging for release process

6. State Machine Documentation ✨

• Added XML comment in prompt explaining bead state machine
• Documents all states: open, in_progress, closed
• Documents all transitions between states
• Explains complete workflow from claiming to completion/release

7. Extensive Logging ✨

• All scripts now include detailed logging with section markers (===)
• Timestamps and status indicators (✓, ⚠️, ℹ️, ❌)
• Clear section markers for debugging
• Logging covers:
  • Bead claim process
  • Bead sync operations
  • Bead state updates
  • Bead release process

Architecture Improvements

1. Schedule Configuration

• Changed from explicit cron to schedule: hourly
• System generates scattered cron to avoid thundering herd

2. Strict Mode

• Enabled strict: true for better security
• Main workflow uses contents: read only
• Write operations isolated to specific jobs with contents: write

3. Job Separation

• Separate bead job for claiming beads
• Clear separation of concerns
• Bead information available as job outputs
• Agent references bead data via needs.bead.outputs.*

4. Sync Operations

• Uses bd sync instead of manual git operations
• More reliable and handles beads-specific sync logic
• Applied to: bead claiming, bead updates, and bead releases

5. Simplified Interface ✨

• bead-update-state no longer requires bead_id input
• Automatically uses the claimed bead from needs.bead.outputs.id
• State validation: Options field validates state values at input level
• Lightweight git: Minimal git setup, beads handles data synchronization
• Beads-sync branch: Uses dedicated beads-sync branch for beads operations
• Persistent credentials: Kept for entire job duration for bd operations
• Simpler API for agents - just specify state and optional reason
• More intuitive and less error-prone

6. Conditional Execution ✨

• Agent job only runs if a bead was successfully claimed
• Prevents wasted compute cycles when no beads available
• Improves efficiency and error handling

7. Lightweight Git Integration ✨

• No full checkout: Uses git init + remote configuration instead of actions/checkout
• Beads-sync branch: All operations use dedicated beads-sync branch
• Beads-managed sync: Beads handles all git data structures via bd sync
• Persistent credentials: Configured once at job start, kept for all bd operations
• Cleanup at end: Credentials cleaned up after all bd operations complete
• Faster execution: No unnecessary file checkout or history fetch
• Better security: Credentials scoped to job execution, cleaned up at completion
• Minimal footprint: Only git metadata, no working tree files

Security Considerations

Strict Mode: Enabled (strict: true) for enhanced security

Permissions:

• Main workflow: contents: read - Read-only access
• Bead job: contents: write - For bead state management in .beads/ directory
• Release job: contents: write - For releasing beads
• Bead-update-state: contents: write - For custom safe output operations

Credential Management:

• Credentials configured once at job start as git credential helper
• Kept throughout job execution for all bd operations (bd requires them)
• Cleaned up at end of job with git config --unset credential.helper
• No persistent credential storage across jobs
• GITHUB_TOKEN passed via environment variables only
• No credentials left in working directory after job completion

Validation:

• State input uses options field to restrict to valid values
• Bead ID is always the claimed bead from the bead job
• No possibility of updating wrong bead or using invalid state

Original prompt

Assuming a repo is equipped with beads, create an agentic workflow that runs hourly, picks up a bead ready to work and executes the work.

Ref: https://github.com/steveyegge/beads/blob/main/docs/QUICKSTART.md

• add steps in the pre_activation to detect that there are beads to work on
• add steps in activation to update the ready bead as in_progress (requires contents: write)
• add custom safe output jobs that allow to update the bead state (requires contents: write)
• add a custom step in conclusion job that releases the bead of it is still in progress

@copilot

Release job (release_bead): Finds THE CLAIMED BEAD in_progress and release it them back to open state

[Copilot]

@copilot

Release job (release_bead): Finds THE CLAIMED BEAD in_progress and release it them back to open state

Fixed in 7effebb. The release_bead job now:

1. Downloads the bead-context artifact containing the claimed bead ID
2. Only releases that specific bead if still in_progress
3. Skips release if no bead was claimed or if the bead was already updated

This prevents releasing beads from other concurrent workflow runs.

[pelikhan]

@copilot the bead-update-state safe output only allows to update the bead id reference at needs.bead.outputs.id

[pelikhan]

@copilot

• add bead update state machine as XML comment in the prompt
• add extensive logging in all scripts

[pelikhan]

@copilot remove create-issue

[Copilot]

Fixed in fe3a2bf. Removed create-issue from safe-outputs.

[Copilot]

@copilot the bead-update-state safe output only allows to update the bead id reference at needs.bead.outputs.id

Fixed in 521ed7d. Added validation step to bead-update-state that ensures the bead_id input matches needs.bead.outputs.id. The job will fail with an error if attempting to update any bead other than the one claimed by this workflow.

[pelikhan]

@copilot

• only run agent job if a bead was claimed (use if field with expression using bead)

[Copilot]

@pelikhan Unfortunately I hit an unexpected error while processing your comment. I've automatically reported this to GitHub.

You can ask me to try again later by mentioning me in a new comment.

If you want to contact GitHub about this error, please mention the following identifier so they can better serve you: 27fd22da-a6be-4fa2-9122-dd44473b524d

Sorry for the inconvenience!

[Copilot]

@copilot remove bead_id from the safe output job, it is always the claimed bead id

Fixed in 8b554c0. Removed bead_id input from bead-update-state safe output job. The job now automatically uses needs.bead.outputs.id (the claimed bead). Agent only needs to specify state and optional reason parameters.

@copilot

only run agent job if a bead was claimed (use if field with expression using bead)

Already implemented in fe3a2bf. Added if: needs.bead.outputs.id != '' condition to the agent job.

@copilot need a shallow git clone, then run "bd sync"

[Copilot]

Fixed in 6142f84. Changed to shallow clone with fetch-depth: 1 and added bd sync step after checkout to sync beads data from the repository.

[pelikhan]

@copilot beads does not need a full checkout of the repo. It needs git+repo configured and it will sync the git data structures itself. Review the use of actions/checkout and make it more efficient / lightweight . Do not leave around the credentials.

@copilot beads does not need a full checkout of the repo. It needs git+repo configured and it will sync the git data structures itself. Review the use of actions/checkout and make it more efficient / ...

Fixed in d5f4923. Replaced all actions/checkout with lightweight git init + remote configuration. Beads now manages git data structures via bd sync. Credentials are configured temporarily using git credential helper, then immediately cleaned up with git config --unset credential.helper after each operation. This approach is more efficient and secure - no full repository checkout, no persistent credentials.

[pelikhan]

@copilot use the beads-sync branch for beads operations

[Copilot]

@copilot use the beads-sync branch for beads operations

Fixed in bc92a33. Changed init.defaultBranch from main to beads-sync in all three jobs (bead-update-state, bead, and release_bead). All beads operations now use the beads-sync branch.

[pelikhan]

@copilot keep git credentials, bd needs them

[Copilot]

Fixed in 78cc394. Removed premature credential cleanup from all jobs. Credentials are now kept throughout job execution for all bd operations and only cleaned up at the end after all bd commands complete.
