Checkpoint

You create, list, or recover lightweight mid-workflow checkpoints that allow a crashed or interrupted workflow to continue from a known-good position rather than restart from scratch.

Triggers

Alternate expressions and non-obvious activations (primary phrases are matched automatically from the skill description):

  • "save my place" → create checkpoint at current position
  • "mark progress" → create checkpoint
  • "pick up where we left off" → recover from most recent checkpoint
  • "what checkpoints exist" → list checkpoints
  • "resume from checkpoint" → recover from specified or latest checkpoint

Trigger Patterns Reference

PatternExampleAction
Create (named)"checkpoint this as iteration-3-complete"Run
aiwg checkpoint create --name iteration-3-complete
Create (anonymous)"create a checkpoint"Run
aiwg checkpoint create
List"show available checkpoints"Run
aiwg checkpoint list
Recover (latest)"recover from the last checkpoint"Run
aiwg checkpoint recover
Recover (specific)"recover checkpoint ckpt_7b2f1a"Run
aiwg checkpoint recover ckpt_7b2f1a

Behavior

When triggered:

  1. Extract intent:

    • Which subcommand:
      create
      ,
      list
      , or
      recover
      ?
    • Is a name or checkpoint ID provided?
    • For recover, should it use the most recent checkpoint or a specific one?
  2. Run the appropriate subcommand:

    # Create — anonymous
    aiwg checkpoint create
    
    # Create — named
    aiwg checkpoint create --name <name>
    
    # List all checkpoints
    aiwg checkpoint list
    
    # Recover — most recent checkpoint
    aiwg checkpoint recover
    
    # Recover — specific checkpoint by ID or name
    aiwg checkpoint recover <id>
    
  3. Checkpoints vs. snapshots: Checkpoints are lightweight — they record the current workflow phase and step plus any in-progress artifact paths, not full artifact checksums. Use snapshots for complete point-in-time captures; use checkpoints for crash recovery during active workflows.

    PurposeCrash recoveryReproducibility
    SizeSmall (phase + step + artifact refs)Full (versions + checksums)

    Use forResume interrupted runReplay from known state
  4. Automatic creation: Agent loops create checkpoints automatically between iterations. Manual

    create
    supplements this for critical workflow milestones.

  5. Storage: Checkpoints are stored in

    .aiwg/checkpoints/
    as lightweight JSON files.

  6. Report the result — on create, confirm the checkpoint ID and position; on recover, confirm which step the workflow will resume from.

Examples

Example 1: Create a named checkpoint

User: "Create a checkpoint after iteration 3 completes"

Extraction: Create subcommand, name

iteration-3-complete

Action:

aiwg checkpoint create --name iteration-3-complete

Response: "Checkpoint

iteration-3-complete
created (ID:
ckpt_7b2f1a
). Recorded position: Construction phase, iteration 3, step 12/15. In-progress artifacts:
.aiwg/working/tests/integration-plan-draft.md
. Stored at
.aiwg/checkpoints/ckpt_7b2f1a.json
."

Example 2: List checkpoints

User: "What checkpoints do we have?"

Extraction: List subcommand

Action:

aiwg checkpoint list

Response:

ID            Name                     Date                  Phase / Step
ckpt_3a8c12   (auto)                   2026-03-28 10:04:51   Construction / iter 1, step 8
ckpt_9f20de   (auto)                   2026-03-29 14:17:33   Construction / iter 2, step 15
ckpt_7b2f1a   iteration-3-complete     2026-03-30 09:55:02   Construction / iter 3, step 12

Example 3: Recover from the latest checkpoint

User: "The workflow crashed — recover from the last checkpoint"

Extraction: Recover subcommand, use most recent

Action:

aiwg checkpoint recover

Response: "Recovering from most recent checkpoint

iteration-3-complete
(ckpt_7b2f1a). Resuming Construction phase, iteration 3, step 12/15. In-progress artifact
.aiwg/working/tests/integration-plan-draft.md
reloaded. Ready to continue."

Example 4: Recover from a specific checkpoint

User: "Recover from checkpoint ckpt_9f20de"

Extraction: Recover subcommand, ID

ckpt_9f20de

Action:

aiwg checkpoint recover ckpt_9f20de

Response: "Recovering from checkpoint

ckpt_9f20de
(auto, 2026-03-29 14:17:33). Resuming Construction phase, iteration 2, step 15/15. No in-progress artifacts. Ready to continue from this position."

Clarification Prompts

If the user's intent is ambiguous:

  • "Should I create a new checkpoint here, list existing checkpoints, or recover from one?"
  • "Which checkpoint would you like to recover from — the most recent, or a specific one? Run
    aiwg checkpoint list
    to see what's available."
