Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00235 |
| Opus 5.5 | $0.00000 | $0.00094 |
| Sonnet 5.5 | $0.00000 | $0.00047 |
| Haiku 4.5 | $0.00000 | $0.00023 |
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 1mo 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

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 3d ago), 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.
