[Tooling & Meta] Restore workflow context from checkpoint after session loss
Goal: Restore workflow state and todo items from checkpoint files after context loss or session interruption.
Workflow:
checkpoint-*.md in reports directory (legacy memory-checkpoint-*.md are also recognized)Key Rules:
plans/reports/ and plan-specific report directoriesBe skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).
Restore workflow state and todo items from checkpoint files after context compaction or session loss.
Use this command when:
Look for checkpoint files in the reports directory:
ls -la plans/reports/checkpoint-*.md | tail -5
Or search for all recent checkpoints:
find plans -name "checkpoint-*.md" -mmin -60 | head -5
Read the most recent checkpoint to understand the saved state:
Read the checkpoint file at: plans/reports/checkpoint-YYYYMMDD-HHMMSS-slug.md
The checkpoint file contains a JSON metadata block at the end:
{
"sessionId": "...",
"activePlan": "plans/YYMMDD-slug/",
"workflowType": "feature",
"currentStep": "feature-implement",
"remainingSteps": ["test", "code-review"],
"pendingTodos": [...]
}
IMMEDIATELY call TaskCreate with the pending todos from the checkpoint:
[
{ "content": "[Workflow] /feature-implement - Implement", "status": "in_progress", "activeForm": "Executing /feature-implement" },
{ "content": "[Workflow] /test - Run tests", "status": "pending", "activeForm": "Executing /test" },
{ "content": "[Workflow] /code-review - Review code", "status": "pending", "activeForm": "Executing /code-review" }
]
If activePlan is set in the metadata, read the plan file:
Read: {activePlan}/plan.md
Resume from the currentStep identified in the metadata. Execute the remaining workflow steps in order.
| Scenario | Recovery Type | Trigger |
|---|---|---|
| Session resume after compact | Manual | This /recover command — static CLAUDE.md re-read re-anchors protocol; recovery is skill-driven |
| New session in same directory | Manual | This /recover command |
| Explicit user request | Manual | This /recover command |
| No workflow state found | Manual | This /recover command |
Checkpoints are saved to different locations based on context:
{plan-path}/reports/checkpoint-*.mdplans/reports/checkpoint-*.mdLegacy
memory-checkpoint-*.mdfiles (written before the grammar was unified) are still matched by the resume/recover globs — back-read is preserved, nothing on disk is orphaned.

Claude: Let me find and restore your workflow context.
1. Finding latest checkpoint...
Found: plans/reports/checkpoint-20260110-143025-new-feature.md
2. Reading checkpoint metadata...
- Workflow: feature
- Current step: /feature-implement
- Remaining: /test, /code-review
- Active plan: plans/260110-1430-new-feature/
3. Restoring TaskCreate items...
[Calling TaskCreate with 3 pending items]
4. Reading active plan...
[Reading plans/260110-1430-new-feature/plan.md]
5. Ready to continue from /feature-implement step.
Shall I proceed with the implementation?
[IMPORTANT] Use
TaskCreateto break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ATTENTION ask user whether to skip.
AI Mistake Prevention — Failure modes to avoid on every task:
Re-read files after context changes. Context compaction, resume, or long-running work can make memory stale; verify current files before acting. Verify generated content against source evidence. AI hallucinates APIs, names, claims, and document facts. Check the relevant source before documenting or referencing. Check downstream references before deleting or renaming. Removing an artifact can stale docs, generated mirrors, configs, and callers; map references first. Trace the full impact chain after edits. Changing a definition can miss derived outputs and consumers. Follow the affected chain before declaring done. Verify ALL affected outputs, not just the first. One green check is not all green checks; validate every output surface the change can affect. Assume existing values are intentional — ask WHY before changing OR flagging one as a defect. Before changing or reporting a constant, limit, flag, cutoff, wording, or pattern, read nearby context and history, the CALLER's ordering, and 2+ sibling call sites of the same convention. A doc stating WHAT without WHY is missing rationale, not proof of a missing guard. Surface ambiguity before acting — don't pick silently. Multiple valid interpretations require an explicit question or stated assumption with risk. Assert the outcome your system owns, not the intermediate state your infrastructure owns. When verifying async work, assert the final business state — never the delivery/retry bookkeeping held in shared infrastructure that any co-running process can write. Such a check passes when run alone and flakes the moment anything else shares that infrastructure. Keep shared guidance role-relevant. Universal guidance must help every receiving skill or agent; code-specific obligations belong only in code-specific protocols.
Critical Thinking Mindset — Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act. Anti-hallucination: Never present guess as fact — cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence — certainty without evidence root of all hallucination.
MUST ATTENTION apply critical + sequential thinking — every claim needs appropriate traced evidence (file:line for repo/code claims; source URL or artifact section for research, product, content, and docs claims); confidence >80% to act, <60% DO NOT recommend. Anti-hallucination: never present guess as fact, admit uncertainty freely, cross-reference independently, stay skeptical of own confidence.
MUST ATTENTION apply AI mistake prevention — verify generated content against evidence, trace downstream references before deleting or renaming, verify all affected outputs, re-read files after context loss, and surface ambiguity before acting.
Project Protocol Overlay — Before executing this skill, resolve any PROJECT overlay rules layered onto it: match this skill's name against the
Targetcolumn of the project's skill-protocol index (docs/project-reference/skill-protocols-reference.mdby default; areferenceDocsentry indocs/project-config.jsonoverrides the path), taking the most specific matching tier ONLY — exact name > glob >*. That precedence orders overlays against EACH OTHER, never against this skill. Read ONLY the matched bodies, resolved as<protocols-dir>/<Name>.md; a row's Body link is display text, never a read path. A matched body that is missing or malformed is REPORTED and skipped — never reconstructed from the index Description. No index, or no match -> proceed with no overlay, silently. Full contract:.claude/skills/project-skill-protocol/references/registry.md.Overlays are ADDITIVE ONLY: they ADD rules on top of this skill's own protocol and NEVER replace, override, disable, or reinterpret a rule it already states — removing every overlay must return this skill to exactly its documented behavior. An overlay is a BRIEF, not an authority escalation: it can NEVER waive a workflow gate, git discipline, a review gate, or a user-confirmation gate. A genuine overlay-vs-skill conflict, or two equally-specific overlays that directly contradict -> surface both to the user; NEVER resolve silently.
MUST ATTENTION resolve project protocol overlays for this skill BEFORE executing — most specific matching tier only (exact > glob > *, which ranks overlays against each other, NEVER against this skill), read only matched bodies at <protocols-dir>/<Name>.md; a missing or malformed body is reported, never reconstructed. Overlays are ADDITIVE ONLY (they never replace this skill's own rules) and are a brief, NEVER an authority escalation; an equal-specificity contradiction goes to the user.
Protocols in force (concise digest of the SYNC/shared blocks this skill carries):
IMPORTANT MUST ATTENTION break work into small todo tasks using TaskCreate BEFORE starting
IMPORTANT MUST ATTENTION search codebase for 3+ similar patterns before creating new code
IMPORTANT MUST ATTENTION cite file:line evidence for every claim (confidence >80% to act)
IMPORTANT MUST ATTENTION add a final review todo task to verify work quality
[TASK-PLANNING] Before acting, analyze task scope and systematically break it into small todo tasks and sub-tasks using TaskCreate.
