How it works

A scan reads a handful of files as text, applies fixed rules and prints what it found. It is a check you run before the agent runs.

1. Scan a repository

Point it at a folder. It finds the agent config files by name, reads them, and follows the scripts they call.

Each finding has a rule ID, a severity from info to critical, the file and line, the evidence, and a confidence level. The same input always gives the same findings: no model decides what is dangerous.

The scan never executes, imports or installs anything from the folder, and it makes no network calls. Secret values that appear in evidence are redacted by known token format.

2. Decide what to accept

The first run on a real repository usually finds things you decide are fine.

Accept the current findings with a baseline. A baseline hides a finding only while its rule, file, JSON path and evidence text stay the same; any change to the evidence is a new finding.

A suppression needs a reason. To hold MCP servers and hooks steady, lock records their hashes and verify reports any later change.

accept and lock

$ tripcord baseline create .$ tripcord lock .$ tripcord verify .

3. Block it in pull requests

Run the check on every pull request so a change cannot add risky config unnoticed.

diff compares the pull request with its base and reports only what it introduced or made worse. Configuration and baselines are read from the base commit, so the pull request cannot switch off its own findings.

The command exits 1 when a finding reaches the threshold, which fails the CI job. A GitHub Action runs the same check on pull requests; JSON and SARIF output feed other tools. CI use needs a license.

in CI

$ tripcord diff origin/main HEAD --fail-on high$ tripcord diff origin/main HEAD --sarif results.sarif

What stays out of scope

So you know where to look elsewhere.

Your application source, dependencies and build scripts are not scanned.
Nothing is monitored while the agent runs, and nothing already executed is undone.
A finding is a pattern match, not proof of bad intent.
