Task Tracking Hierarchy

Three systems serve different purposes. Use the right tool for the job.

Linear is for human-visible project tracking. Beans is for agent implementation memory. Both systems work together with bidirectional linking.

When to Use Each System

TodoWrite — User-facing progress indicator for the current session:

• Multi-step work (3+ steps) where the user benefits from seeing progress
• Skip for background/non-user-facing work
• Skip for trivial single-step tasks

Beans — Persistent agent memory (only if the project uses Beans):

• All non-trivial work (3+ steps)
• Work that may span sessions or context boundaries
• Discovered work during implementation
• Anything needing an audit trail
• Skip for trivial single-step tasks (typo fixes, quick lookups)

Linear — Human-level tracking:

• Epics and milestones
• User-facing features
• Scope/timeline changes
• Decisions requiring human input
• Security concerns

Rule: Use Both TodoWrite and Beans Together

For user-facing, non-trivial work:

1. Create a bean first (beans create ... -s in-progress)
2. Create a TodoWrite list for live user visibility
3. Update both as you progress
4. TodoWrite items should mirror bean checklist items

For non-user-facing work (background agents, audit-only):

• Use Beans only
• Skip TodoWrite

Rule: Update Bean Checklists Immediately

After completing each checklist item in a bean:

1. Edit the bean file: - [ ] → - [x]
2. This creates a recoverable checkpoint if context is lost
3. The I/O overhead is acceptable for persistence

Rule: Commit Bean Changes With Code

Every code commit includes its associated bean file updates:

git commit -m "[TYPE] Description" -- src/file.ts .beans/issue-abc123.md

This keeps bean state synchronized with codebase state.

Starting Work on a Linear Ticket

When beginning work on a Linear ticket (e.g., ZCO-123):

1. Run beans query '{ beans(filter: { type: ["epic"], search: "\"<linear-ticket-id>\"" }) { id title status } }' to find an existing related Beans epic
2. If none exists, create one automatically:

   beans create "<linear-ticket-id>: <design-name>" --type epic --body "<description>"
   

3. All implementation sub-tasks go under this epic as child issues using --link parent:<epic-id>

Git Commit Messages

All commits related to a Linear ticket MUST reference it:

<descriptive message>

Part of ZCO-123.

When also closing a Beans issue:

<message>

Part of ZCO-123. Closes beans-1234.

This ensures Linear ticket traceability in git history even after Beans cleanup.

Rule: Discovered Work Goes to Beans First

When you discover work during implementation:

1. Create a bean immediately (--tag discovered), add a line that explains that it was created while working on current bean, and name the current bean.
2. Assess if it needs Linear escalation
3. Never ignore discovered work due to context pressure

Rule: Escalate Discovered Work to Linear

Create a Linear ticket for discovered work IF it:

• Affects scope or timeline of current work
• Requires human decision or approval
• Represents user-facing changes
• Is a security concern
• Is significant enough to track at project level

For purely technical implementation details (refactoring, test fixes, code cleanup), keep them in Beans only with --tag implementation-detail.

When Beans work reveals an epic-level concern:

1. Create the bean with --type epic
2. Immediately create a corresponding Linear ticket, tag it as "Epic"
3. Cross-reference both directions

Querying Work

• beans list --status backlog — Find unblocked work to do next
• beans list --search "<linear-ticket-id>" — All Beans issues for a Linear ticket
• beans show <id> — View issue details including dependencies

Provenance for Context

When revisiting a Linear ticket that seems vague, use Beans to trace its origin:

• Find the Beans epic: beans list --type epic | rg --fixed-strings '<linear-ticket-id>'
• Use --tag discovered --link:<epic-ticket-id> to understand why work was filed
• This provides context that Linear alone cannot

Completing a Linear Ticket

When all Beans issues under an epic are closed:

1. Update the Linear ticket with a summary:
   • What was implemented
   • Any discovered work filed as separate Linear tickets
   • Notable decisions or deviations from original scope
2. Move the Linear ticket to appropriate status

The Linear ticket becomes the permanent record; Beans issues are ephemeral working memory.
