What it does
Checkpoint is an agent skill from hashgraph-online/awesome-codex-plugins. Save bounded progress as kernel.checkpoint/v1 for exact resume after reset. Triggers: checkpoint, save progress, context reset, compact soon, long task.
Its SKILL.md is about 730 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Session handoff. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Session handoff
Example prompts
- “/checkpoint”
Requirements
- Pre-approved tools (allowed-tools): Read, Bash, Grep, Glob, Write
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Gather provenance

What it can do on your machine
Read from SKILL.md and the folder at commit 16b4156. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadBashGrepGlobWrite
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Checkpoint loads about 725 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 270 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Bash, Grep, Glob, Write
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

<skill id="checkpoint"><purpose>
The small resumable manifest. A handoff transfers a whole session; a checkpoint records
bounded progress INSIDE a long-running task so work can continue after a context reset
with a fresh, minimal context instead of an inherited transcript.When to fire (EXP-L21: attention efficiency decays to ~11% late-session; a reset from a checkpoint restores the flat ~50-70k load-bearing line):
- a long task crosses a natural boundary (a commit lands, a phase completes)
- context is about to compact, or the session is degrading (anchor-drift, I0.13)
- the manifest's execution.checkpoints list says so
Checkpoint vs handoff: same task + same session continuation → checkpoint.
Ending the session / transferring to a future session with decisions and policy → handoff.
</purpose>
<flow>
1. Gather provenance:
```bash
git branch --show-current && git rev-parse HEAD && git status --short
```Write
_meta/checkpoints/{task}-{timestamp}.jsonper schemas/kernel.checkpoint.v1.schema.json:- task: goal + handoff_ref/contract_ref if they exist
- steps_completed: each with EVIDENCE (commit sha, test output, command result), never intent. Receipts describe intent; files describe reality.
- current_outputs: files produced so far
- provenance.dirty_tree_sha256: when dirty, sha256 of
git diff --binary HEAD - pending_steps: what remains, in order
- resume: position (exact place in the work), entrypoint (skill to re-enter), next_operation (the LITERAL first action — "retarget tests/run-tests.sh lines ~1250 registration tests", not "continue the migration")
- context (optional): required selectors + budget if the resume should be bounded
Quote every sha/commit string (all-digit shas parse as integers and fail validation).
Validate — MANDATORY:
bash "${CLAUDE_PLUGIN_ROOT:-.}/orchestration/manifest/kernel-manifest" validate _meta/checkpoints/{file}.jsonRecord:
bash agentdb write-end '{"skill":"checkpoint","saved_to":"_meta/checkpoints/{file}.json","position":"..."}'
Resume path: /kernel:ingest discovers the newest manifest automatically
(kernel-manifest latest — checkpoints and handoffs share discovery), or accepts an
explicit path.
</flow>
<hard_stops>
- steps_completed without evidence → not a checkpoint, a hope. Add evidence or move the step to pending_steps.
- unvalidated json → does not exist. Validate before reporting done. </hard_stops>

Codex loads it when a task matches its description.
Can I use Checkpoint in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add hashgraph-online/awesome-codex-plugins --skill checkpoint -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/checkpoint, .gemini/skills/checkpoint, .github/skills/checkpoint and .opencode/skills/checkpoint in your project.
What does Checkpoint need to run?
Going by SKILL.md and its folder, Checkpoint needs the command-line tools its instructions call (git). Its frontmatter pre-approves these tools: Read, Bash, Grep, Glob, Write.
Does Checkpoint access the network?
