Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

checkpoint scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to checkpoint — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Checkpoint Command

Create or verify a checkpoint in your workflow.

Usage

/checkpoint [create|verify|list] [name]

Create Checkpoint

When creating a checkpoint:

  1. Run /verify quick to ensure current state is clean
  2. Create a git stash or commit with checkpoint name
  3. Log checkpoint to .claude/checkpoints.log:
echo "$(date +%Y-%m-%d-%H:%M) | $CHECKPOINT_NAME | $(git rev-parse --short HEAD)" >> .claude/checkpoints.log
  1. Report checkpoint created

Verify Checkpoint

When verifying against a checkpoint:

  1. Read checkpoint from log

  2. Compare current state to checkpoint:

    • Files added since checkpoint
    • Files modified since checkpoint
    • Test pass rate now vs then
    • Coverage now vs then
  3. Report:

CHECKPOINT COMPARISON: $NAME
============================
Files changed: X
Tests: +Y passed / -Z failed
Coverage: +X% / -Y%
Build: [PASS/FAIL]

List Checkpoints

Show all checkpoints with:

  • Name
  • Timestamp
  • Git SHA
  • Status (current, behind, ahead)

Workflow

Typical checkpoint flow:

[Start] --> /checkpoint create "feature-start"
   |
[Implement] --> /checkpoint create "core-done"
   |
[Test] --> /checkpoint verify "core-done"
   |
[Refactor] --> /checkpoint create "refactor-done"
   |
[PR] --> /checkpoint verify "feature-start"

Arguments

$ARGUMENTS:

  • create <name> - Create named checkpoint
  • verify <name> - Verify against named checkpoint
  • list - Show all checkpoints
  • clear - Remove old checkpoints (keeps last 5)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
