checkpoint

checkpoint is a command for coding agents from tdimino/claude-code-minoan. It costs 0 tokens per session (235 once invoked), scanned A, original, MIT.

A command that creates a named checkpoint, or bookmark, containing the current session’s Git branch, commit, workflow phase, changed files, and optional summary.

In plain words
What is it for?
Use it to mark milestones such as finishing a module, starting a refactor, or preparing for deployment.
Why use it?
It records where work stands before or after an important change, making progress easier to review later.

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 5d 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.

What it actually says

Create Session Checkpoint

Create a named bookmark in the current session capturing: label, git state (branch + HEAD commit), current workflow phase, modified files, and optional summary. Checkpoints are stored in tracker.db and queryable via /checkpoint-list.

Arguments

$ARGUMENTS - checkpoint label (required), optionally followed by --summary "description".

Instructions

if [ -z "$ARGUMENTS" ]; then
  echo "Usage: /checkpoint <label> [--summary \"description\"]"
  exit 1
fi

node ~/.claude/skills/claude-tracker-suite/scripts/checkpoint-session.js create $ARGUMENTS

Examples

  • /checkpoint "finished auth module" — label only
  • /checkpoint "started refactor" --summary "breaking out auth into separate service"
  • /checkpoint "pre-deploy" — mark state before risky action
  • /checkpoint-list — query checkpoints
  • /tag — attach keyword tags to sessions
  • /claude-tracker-search — search sessions by keyword

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.

checkpoint is a command published in the GitHub repository tdimino/claude-code-minoan (41 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 235 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
