Persisting Progress Across Sessions

Use this skill when a session ends mid-orchestration (context compaction, manual restart, crash) and you need to resume without repeating completed work.

The Resume Protocol

Step 1 — Find the Incomplete MANIFEST

# List all in-progress features
ls .jonggrang/.output/features/

Look for a MANIFEST.yaml with status: running or status: paused. Read it:

cat .jonggrang/.output/features/{feature_id}/MANIFEST.yaml

Key fields to read:

• current_phase — next phase to execute
• active_phases — which phases this run is executing
• phases — per-phase status (completed / failed / pending)
• agents — which agents ran and their output paths
• validation — review_passed, tests_passed, coverage_met

Step 2 — Reconstruct Context from Phase Outputs

Do NOT re-run completed phases. Read their outputs instead:

# Phase 7 output (architecture plan)
cat .jonggrang/.output/features/{feature_id}/07-lead-architecture-plan.json

# Phase 8 output (implementation)
cat .jonggrang/.output/features/{feature_id}/08-developer-{task_id}.json

# Any reviewer reports
cat .jonggrang/.output/features/{feature_id}/09-reviewer-report.json

Step 3 — Identify Resumption Point

current_phase in MANIFEST  →  start from this phase
phases[N].status == 'failed'  →  retry this phase
phases[N].status == 'completed'  →  skip, output already exists

Step 4 — Resume the Orchestration

Call orchestrating-feature with resume: true and the feature_id. Pass the reconstructed context as a summary — do NOT re-read all source code; trust the phase outputs.

Resuming feature: {feature_id}
Completed phases: 1, 2, 3, 4, 7, 8
Current phase: 9 (design-verification)
Architecture plan: [summary from 07-lead-architecture-plan.json]
Implementation: [summary from 08-developer.json]

Cross-Session State Guarantee

The MANIFEST survives session resets. The ephemeral state does NOT:

File	Survives reset?	Action on resume
MANIFEST.yaml	✅ Yes	Read to get current phase
feedback-loop-state.json	❌ No	Assume clean state, re-run review/test if dirty_bit lost
compaction-state.json	❌ No	Will be refreshed on next Task spawn
session-roles.json	❌ No	Will be re-populated on next session start

When Tests Were Running

If context compacted during phase 13 (testing), check validation.tests_passed in MANIFEST:

• false → re-spawn tester
• true → proceed to phase 14 (coverage)

Stale Lock Cleanup

On resume, clean up any stale lock files left by crashed agents:

const { cleanStaleLocks } = require('./lib/locks');
cleanStaleLocks(projectRoot);  // removes locks older than 30 minutes

Example Resume Flow

Session ended at phase 9.
MANIFEST shows: phases[8].status = 'completed', phases[9].status = 'running'

Resume steps:
1. Read 07-lead-architecture-plan.json → architecture context
2. Read 08-developer-*.json → what was implemented
3. Re-spawn reviewer for phase 9 with the implementation context
4. Continue from phase 9 forward
