What it does
Compass Integrity is an agent skill from chunxiaoxx/nautilus-compass. Use when the user is about to rely on prior session memory for a non-trivial decision, or when something feels off about a recall hit — runs the Merkle chain check, drift summary, and daemon liveness in one pass and surfaces any tampering, drift bursts, or daemon-down state before the user acts on stale or corrupted memory.
Its SKILL.md is about 1.3k 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 Agent memory. It works with Model Context Protocol. The repository describes itself as: Open memory & reliability layer for AI agents + independent judging/verification (NACRE judge, caliber-bench meta-benchmark, preregistered criteria) — by Nautilus Platform.
When your agent uses it
- The user is about to rely on prior session memory for a non-trivial decision
- Something feels off about a recall hit — runs the Merkle chain check
- Daemon liveness in one pass and surfaces any tampering
- Daemon-down state before the user acts on stale
Example prompts
- “/compass-integrity”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- User says "do we remember", "did we discuss", "based on past sessions" — they're about to lean on memory.
- User points at a specific memory file or session ID — verify the chain covers it cleanly.
- Drift incident already suspected ("why did the assistant flip on X?", "this looks like a regression") — pull recent drift history.
- Session start in a project with memory/, before any recall fires — preflight.
- After a crash, conflict resolution, or merge — chain may have been broken by a non-writer edit.
What it can do on your machine
Read from SKILL.md and the folder at commit 32f7e92. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Compass Integrity loads about 1.3k tokens when it runs. Until then it costs about 86 tokens; SKILL.md has 530 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 passed
The automated check found no risky patterns in SKILL.md.
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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 530 words (~1,274 tokens).
“Compass writes a Merkle hash chain over project memory and a per-session drift signal. Both can be silently broken — a chain mismatch means a memory file was edited outside the writer; a drift-red session means the past assistant output…”

Questions about Compass Integrity
What does Compass Integrity do?
A skill your agent uses when the user is about to rely on prior session memory for a non-trivial decision, or when something feels off about a recall hit — runs the Merkle chain check, drift…. Compass Integrity is an agent skill from chunxiaoxx/nautilus-compass. Use when the user is about to rely on prior session memory for a non-trivial decision, or when something feels off about a recall hit — runs the Merkle chain check, drift summary, and daemon liveness in one pass and surfaces any tampering, drift bursts, or daemon-down state before the user acts on stale or corrupted memory.
When should I use Compass Integrity?
Compass Integrity fits situations like: the user is about to rely on prior session memory for a non-trivial decision; something feels off about a recall hit — runs the Merkle chain check; daemon liveness in one pass and surfaces any tampering; daemon-down state before the user acts on stale.
How do I install Compass Integrity in Claude Code?
Run `npx skills add chunxiaoxx/nautilus-compass --skill compass-integrity -a claude-code`. Or copy the skill folder (skills/compass-integrity in chunxiaoxx/nautilus-compass) into .claude/skills/compass-integrity in your project. Claude Code loads it when a task matches its description.
How do I install Compass Integrity in Codex?
Run `npx skills add chunxiaoxx/nautilus-compass --skill compass-integrity -a codex`. Or copy the skill folder (skills/compass-integrity in chunxiaoxx/nautilus-compass) into .agents/skills/compass-integrity in your project. Codex loads it when a task matches its description.
Can I use Compass Integrity 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 chunxiaoxx/nautilus-compass --skill compass-integrity -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/compass-integrity, .gemini/skills/compass-integrity, .github/skills/compass-integrity and .opencode/skills/compass-integrity in your project.
What does Compass Integrity need to run?
SKILL.md names no scripts, command-line tools or credentials: Compass Integrity is instructions for the agent only.
Does Compass Integrity access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Compass Integrity safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Compass Integrity use?
Compass Integrity has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Compass Integrity use?
About 1.3k tokens (SKILL.md is roughly 5.1k 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 Compass Integrity?
