What it does
Checkpoint is an agent skill from ipea/geobr. Save a structured state snapshot the next session can resume from — active plan, decisions and why, file pointers with line numbers, open questions, next 1-3 actions, and what to deliberately forget. Use before a break, a model switch, a collaborator handoff, or when context is approaching auto-compaction. Use when the user says "checkpoint", "save state", "where am I", "compress", "distil this session", "wrap up for handoff", "before we hit auto-compact".
Its SKILL.md is about 1.4k 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 Testing & QA. The repository describes itself as: Easy access to official spatial data sets of Brazil in R and Python.
When your agent uses it
- The user says checkpoint
- Distil this session
- Wrap up for handoff
- Before we hit auto-compact
Example prompts
- “checkpoint”
- “save state”
- “where am I”
- “/checkpoint”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Read, Write, Glob, Grep, Bash
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Gather state
- Write the checkpoint
- Propose memory updates (skip with --no-memory)
- Report
What it can do on your machine
Read from SKILL.md and the folder at commit 0969f92. 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:
ReadWriteGlobGrepBash
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 1.4k tokens when it runs. Until then it costs about 118 tokens; SKILL.md has 369 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, Write, Glob, Grep, Bash
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.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 369 words (~1,441 tokens).
“problem at two moments. The stop-point shape is adapted from Hugo Sant'Anna's clo-author v4.2.0; the "discarded as noise" section is from Breunig's long-context failure modes (dbreunig.com/2025/06/22/how-contexts-fail-and-how-to-fix-them.html) — naming failed hypotheses explicitly stops them being re-quoted by a future session. -->”

When should I use Checkpoint?
Checkpoint fits situations like: the user says checkpoint; distil this session; wrap up for handoff; before we hit auto-compact.
How do I install Checkpoint in Claude Code?
Run `npx skills add ipea/geobr --skill checkpoint -a claude-code`. Or copy the skill folder (.claude/skills/checkpoint in ipea/geobr) into .claude/skills/checkpoint in your project. Claude Code loads it when a task matches its description.
How do I install Checkpoint in Codex?
Run `npx skills add ipea/geobr --skill checkpoint -a codex`. Or copy the skill folder (.claude/skills/checkpoint in ipea/geobr) into .agents/skills/checkpoint in your project. 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 ipea/geobr --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). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Read, Write, Glob, Grep, Bash.
Does Checkpoint access the network?
SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Checkpoint safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Checkpoint use?
No licence was found for Checkpoint or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Checkpoint use?
About 1.4k tokens (SKILL.md is roughly 5.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Checkpoint?
Skills that share tags, products or a category with Checkpoint: Web Application Testing (anthropics/skills, 180k stars), Diagnosing Bugs (fossasia/eventyay-interpretation, 1.6k stars), TDD (fossasia/eventyay-interpretation, 1.6k stars) and TDD Workflow (hellangleZ/burn-in-cceverywhere-ralph, 112 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
