Checkpoint Resume
Rate-limit-resilient pipeline orchestrator. Saves progress to .claude/pipeline-state.json after every phase so long sessions survive interruptions.
Quick Reference
| Category | Rule | Impact | Key Pattern |
|---|
| Phase Ordering | ${CLAUDE_SKILL_DIR}/rules/ordering-priority.md | CRITICAL | GitHub issues/commits first, file-heavy phases last |
| State Writes | ${CLAUDE_SKILL_DIR}/rules/state-write-timing.md | CRITICAL | Write after every phase, never batch |
| Mini-Commits | ${CLAUDE_SKILL_DIR}/rules/checkpoint-mini-commit.md | HIGH | Every 3 phases, checkpoint commit format |
Total: 3 rules across 3 categories
On Invocation
If .claude/pipeline-state.json exists: run scripts/show-status.sh to display progress, then ask to resume, pick a different phase, or restart. Load Read("${CLAUDE_SKILL_DIR}/references/resume-decision-tree.md") for the full decision tree.
If no state file exists: ask the user to describe the task, build an execution plan, write initial state via scripts/init-pipeline.sh <branch>, begin Phase 1.
Execution Plan Structure
{
"phases": [
{ "id": "create-issues", "name": "Create GitHub Issues", "dependencies": [], "status": "pending" },
{ "id": "commit-scaffold", "name": "Commit Scaffold", "dependencies": [], "status": "pending" },
{ "id": "write-source", "name": "Write Source Files", "dependencies": ["commit-scaffold"], "status": "pending" }
]
}
Phases with empty dependencies may run in parallel via Task sub-agents (when they don't share file writes).
After Each Phase
- Update
.claude/pipeline-state.json — see Read("${CLAUDE_SKILL_DIR}/rules/state-write-timing.md")
- Every 3 phases: create a mini-commit — see
Read("${CLAUDE_SKILL_DIR}/rules/checkpoint-mini-commit.md")
References
Load on demand with Read("${CLAUDE_SKILL_DIR}/references/<file>"):
| File | Content |
|---|
references/pipeline-state-schema.md | Full field-by-field schema with examples |
references/pipeline-state.schema.json | Machine-readable JSON Schema for validation |
references/resume-decision-tree.md | Logic for resuming, picking phases, or restarting |
Scripts
scripts/init-pipeline.sh <branch> — print skeleton state JSON to stdoutscripts/show-status.sh [path] — print human-readable pipeline status (requires jq)
Key Decisions
| Decision | Recommendation |
|---|
| Phase granularity | One meaningful deliverable per phase (a commit, a set of issues, a feature) |
| Parallelism | Task sub-agents only for phases with empty dependencies that don't share file writes |
| Rate limit recovery | State is already saved — re-invoke /checkpoint-resume to continue |
Plan mode preserved across --resume (CC 2.1.132+) — --permission-mode plan is honored on resume, and ExitPlanMode re-applies plan mode for the rest of the session. See configure/references/cc-version-settings.md (## CC 2.1.132 Settings).
