A command that saves a snapshot of the current coding session for later resumption.

Use it to record the Git branch and commit, project folder, optional notes, and a reference to the optimizer's session state, then restore the snapshot later.

It preserves key project details and your notes when you need to stop work or move to a fresh session.

checkpoint — Command for Claude Code by kristijankopacevic

Install

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.

Clone the repo

git clone --depth 1 https://github.com/kristijankopacevic/optiflow-mcp

Made for: Claude Code.

Or install optiflow, the plugin that ships this one along with the rest of its 4 commands, 5 hooks, 1 MCP server.

Per session 38 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 356 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00038	$0.00356
Opus 5.5	$0.00015	$0.00142
Sonnet 5.5	$0.00008	$0.00071
Haiku 4.5	$0.00004	$0.00036

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 2mo 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

Save an optiflow session-handoff checkpoint and tell the user where it was written.

The real command Claude Code exposes for this is /optiflow:checkpoint (the plugin namespace prefix is not optional — there is no bare /checkpoint). It writes a JSON file under .optiflow/checkpoints/ in the current project, containing:

the current git branch/HEAD (auto-derived via real git calls; null if cwd isn't a repo or has no commits yet),
the current working directory,
$ARGUMENTS (if any) as the checkpoint's sole decisions[] entry — this is the ONLY way decisions[]/nextSteps[]/openFiles[] get populated; a hook-triggered auto-checkpoint (on PreCompact/SessionEnd) can never supply free-text like this, so if the user wants a next-session-ready summary, $ARGUMENTS matters,
a REFERENCE to token-optimizer-mcp's own session state (never a copy of it — see docs/modules.md).

Run:

optiflow checkpoint "$ARGUMENTS"

After it runs, tell the user the checkpoint id it printed and that /optiflow:restore (or /optiflow:restore <id>) will render it back later, in a fresh session if needed.

Changes

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.
