Automated summary

Saves a snapshot of the current dialogue session to a markdown file so work can be resumed later.

Strengths

Organizes the checkpoint into clear sections (goal, progress, decisions, pending tasks)
Automatically creates the .claude/checkpoints/ directory with a timestamped filename
Captures technical context such as file paths and commands needed to resume
Triggers with a simple /ckpt command

Limitations

Summary quality depends entirely on what the agent actually retained from the dialogue
No automatic resume mechanism: the file must be read back manually
No versioning or cleanup of older checkpoints

When to use it

Use it before interrupting a long or complex session to preserve decisions and current progress.

When not to use it

Unnecessary for a short one-off task whose context can be restated in a few sentences.

Security analysis

Safe

Quality score90/100

The skill only summarizes the current dialogue and writes a local markdown checkpoint under .claude/checkpoints/. It does not instruct destructive actions, network access, secret exfiltration, obfuscation, or safety bypasses. The file-writing behavior is legitimate and scoped to the project directory.

Checkpoint Skill

Name: Save Session Checkpoint
Author: Skills Guide Bot

Save a checkpoint of the current dialogue for resuming work later.

Instructions

When invoked, create a checkpoint file that summarizes the current session:

Generate a summary of the dialogue up to this point, including:
- Session Goal: What the user is trying to accomplish
- Progress Made: Key actions completed, files created/modified
- Current State: Where we are in the workflow
- Key Decisions: Important choices or configurations made
- Pending Tasks: What remains to be done
- Important Context: File paths, variable names, technical details needed to resume
Save the checkpoint to a markdown file:
- Location: .claude/checkpoints/ directory
- Filename format: ckpt_YYYYMMDD_HHMMSS.md (using current timestamp)
- If the checkpoints directory doesn't exist, create it
Output format for the markdown file:

# Session Checkpoint

**Created**: [timestamp]
**Working Directory**: [current directory]

## Session Goal
[Brief description of what the user is trying to accomplish]

## Progress Summary
[Numbered list of completed tasks and milestones]

## Current State
[Description of where we are in the workflow]

## Key Decisions Made
[Important choices, configurations, or approaches decided]

## Files Modified/Created
[List of relevant files with brief descriptions]

## Pending Tasks
[What still needs to be done]

## Resume Context
[Technical details, commands, or context needed to continue work]

## Next Steps
[Suggested actions when resuming this session]

Confirm the checkpoint was saved and display the file path.

User-Invocable

This skill can be invoked with /ckpt to save the current session state.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/save-session-checkpoint-ms2s7c5t/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/save-session-checkpoint-ms2s7c5t' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/save-session-checkpoint-ms2s7c5t/download' --output '.skill-downloads/save-session-checkpoint-ms2s7c5t/SKILL.md.part' && mv '.skill-downloads/save-session-checkpoint-ms2s7c5t/SKILL.md.part' '.skill-downloads/save-session-checkpoint-ms2s7c5t/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

test -f '.skill-downloads/save-session-checkpoint-ms2s7c5t/SKILL.md' && test -s '.skill-downloads/save-session-checkpoint-ms2s7c5t/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/ckpt' && cp -R '.skill-downloads/save-session-checkpoint-ms2s7c5t' '.claude/skills/ckpt'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation

openskills install './.skill-downloads/save-session-checkpoint-ms2s7c5t'

openskills read 'save-session-checkpoint-ms2s7c5t'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/save-session-checkpoint-ms2s7c5t/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
