Eve Plan Implementation

Eve Plan Implementation (Jobs)

Translate a plan document into Eve jobs, parallelize work, and drive review/verification through job phases and dependencies.

Orchestration model: The root epic is the orchestrator — it plans, delegates, and coordinates but does not execute heavy work itself. Phase jobs are sub-orchestrators that break a phase into tasks. Task jobs are workers — each one receives a self-contained description and executes independently with no access to the parent's context.

When to Use

• A plan/spec exists and the work should be orchestrated as Eve jobs.
• The initial job says "use eve-plan-implementation to implement the plan."

Workflow

1) Load context (orchestrator)

• Read the plan doc and extract phases, deliverables, and blockers.
• If present, read AGENTS.md for repo-specific rules.
• Fetch current job context:

  eve job current --json
  

• Stay lightweight: the orchestrator reads just enough to plan the breakdown. Delegate deep analysis (reading large files, exploring code) to worker jobs.

2) Create or confirm the root epic (orchestrator)

If the root job does not exist, create one:

eve job create \
  --project $EVE_PROJECT_ID \
  --description "Implement <plan name>" \
  --review human \
  --phase backlog

If a root job already exists, use it as the orchestrator. The root epic never executes implementation work — it creates phase jobs, wires up dependencies, and waits.

3) Break down into phase jobs (sub-orchestrators)

Create one child job per plan phase. Each phase job acts as a sub-orchestrator: it breaks its scope into task jobs and coordinates them.

eve job create \
  --project $EVE_PROJECT_ID \
  --parent $EVE_JOB_ID \
  --description "Phase: <name>. Deliverable: <artifact/result>" \
  --phase ready

Add dependencies so the parent waits on each phase:

eve job dep add $EVE_JOB_ID $PHASE_JOB_ID --type waits_for

4) Create task jobs under each phase (workers)

Split each phase into 2-6 atomic tasks with clear deliverables.

If a phase has only one task, execute it directly in the phase job rather than creating a child — avoid unnecessary orchestration overhead.

For multi-task phases, create child worker jobs. Each worker description must be self-contained: the executing agent has no access to the parent's context, the plan document, or prior conversation. Include in the description:

• The objective and deliverable
• Relevant file paths and module names
• Any constraints, conventions, or context the worker needs to succeed

eve job create \
  --project $EVE_PROJECT_ID \
  --parent $PHASE_JOB_ID \
  --description "Task: <objective>. Deliverable: <result>. Files: <paths>. Context: <anything the worker needs>" \
  --phase ready

Make the phase wait on its tasks:

eve job dep add $PHASE_JOB_ID $TASK_JOB_ID --type waits_for

5) Parallelize by default

• Independent tasks should have no dependencies and run in parallel.
• Use blocks only for true sequencing requirements.

6) Execute tasks and update phases

Workers pick up task jobs and execute them independently. Each worker:

1. Reads its own job description for scope and context.
2. Does the work (reads files, writes code, runs tests).
3. Reports completion.

eve job update $TASK_JOB_ID --phase active
# do the work
eve job submit $TASK_JOB_ID --summary "Completed <deliverable>"

If no review is required:

eve job close $TASK_JOB_ID --reason "Done"

7) Verification and review

• Add a dedicated verification job (tests, manual checks) gated after implementation tasks.
• Submit the phase job when all tasks are complete.
• When all phases complete, submit the root epic for review.

8) Orchestrator waiting signal

After an orchestrator (root or phase) creates its child jobs and wires dependencies, it should return a waiting signal. This frees the orchestrator's resources while children execute in parallel:

{
  "eve": {
    "status": "waiting",
    "summary": "Spawned child jobs and added waits_for relations"
  }
}

Context Management

Orchestrators should stay lightweight:

• Read just enough to plan the decomposition — don't analyze entire codebases.
• Push context into child descriptions — file paths, conventions, constraints.
• Delegate reading and analysis to workers. A worker that needs to understand a module should read it itself.
• Avoid duplicating work — if two tasks need the same context, mention the shared source in both descriptions rather than summarizing it for them.

Minimal Mapping from Beads to Eve Jobs

• Epic -> root job (issue_type via --type if available).
• Phase -> child job under the epic.
• Task -> child job under the phase.
• bd dep add -> eve job dep add <parent> <child> --type waits_for
• bd ready/blocked -> eve job dep list <id> + eve job list --phase ...

Optional: Git controls template

If tasks require code changes on a shared branch:

eve job create \
  --project $EVE_PROJECT_ID \
  --description "Task: <objective>" \
  --git-ref main \
  --git-ref-policy explicit \
  --git-branch feature/<name> \
  --git-create-branch if_missing \
  --git-commit required \
  --git-push on_success

Keep git controls consistent across tasks so all changes land in one PR.
