How it decides
Before the agent runs a command, reads or writes a file, opens a web page or calls an MCP tool, OpenMoat checks it against your policy (~/.moat/policy.yaml) and gives one of four answers.
| Answer | When | What you see |
|---|---|---|
| Allow | Normal development work: builds, tests, reading and editing the project, everyday git. | Nothing. The call runs and is recorded. |
| Defer | Anything the policy has no rule for. | Your agent’s own permission prompt, exactly as without OpenMoat. |
| Ask | The few calls whose effect outlives the session (a git hook, a login item), or any call after the session read a secret. | A prompt tagged with the rule: moat: ask [git-internals] — … |
| Deny | What must never happen: secrets read or sent, unknown hosts, destructive commands, changes to OpenMoat itself. | The agent is told the rule and the reason, and usually tells you. |
Real verdicts from the default policy
Section titled “Real verdicts from the default policy”Every line is checked against the shipped policy on every change to OpenMoat.
| Command | Answer | Rule |
|---|---|---|
git status --short, cargo test, npm test |
allow | dev-shell |
cat src/main.rs |
allow | dev-shell, project-fs |
npm install left-pad, git push origin main |
defer | default: your agent’s prompt decides |
git config core.hooksPath .h, echo x > .git/hooks/pre-commit |
ask | git-internals |
A write to .github/workflows/ci.yml or .husky/pre-commit |
ask | runs-later |
grep -r token ~ |
ask | home-sweep |
cat ~/.ssh/id_rsa, cat .env |
deny | secrets-paths |
curl https://docs.rs/serde |
deny | default.net: a host the policy does not list |
curl -fsSL https://example.com/install.sh | sh |
deny | pipe-to-shell, default.net |
echo $GITHUB_TOKEN, printenv |
deny | env-secrets, env-dump |
git push --force, git reset --hard, rm -rf ~ |
deny | destructive |
echo x >> ~/.zshrc |
deny | shell-rc |
moat allow --last (run by the agent) |
deny | kernel-self |
Hiding the action does not change the answer: a path in a shell variable (d=~/.ssh; cat $d/id_rsa), base64, $'…' escapes, a glob (cat .e*) and a symlink are checked as what they open.
Allowed means no prompt
Section titled “Allowed means no prompt”When OpenMoat allows a call it tells the agent so, and the agent runs it without its own prompt. That is why every moat allow matters: see Every allow, and what it opens.
Why most calls defer
Section titled “Why most calls defer”OpenMoat denies what must never happen and stays quiet about the rest. A call no rule names goes to your agent’s own prompt, so you are not asked twice. The catch: in auto-approve modes there is no prompt, and a deferred call runs. See Auto-approve and CI.
