  • 🛡️ SCA: Software Composition Analysis
  • 🔐 Secrets Detection: Secrets Management
  • 📜 License Compliance: License Compliance
  • 🛠️ End Of Life: End-of-Life Software Packages
  • 📊 Coverage: Test Coverage
  • 📊 Performance Testing: Test Performance and Reliability
  • 🧑‍💻 Linter: Code Linting
  • 🧪 Unit Tests: Automated Unit Testing
  • 🔎 SAST: Static Application Security Testing
  • 🏗️ IaC Security: Infrastructure-as-Code Misconfiguration Scanning
  • 🔗 Supply Chain: SBOM Generation, Signing and Provenance
  • 🧱 Workflow Security: Hardening of the pipeline definition itself

Usage Examples

Basic Usage

Scan a repository for CI/CD improvement suggestions:

zanadir scan --dir /path/to/your/repo

Output Formats

Zanadir supports three output formats: table (default), JSON and SARIF.

Table Output (Default)

zanadir scan --dir . --output table

Sample Output:

Coverage 10/11 - 1 category needs attention:

|--------------------------------|--------------------------------|-------------------|
|            CATEGORY            |          DESCRIPTION           |  SUGGESTED TOOLS  |
|--------------------------------|--------------------------------|-------------------|
| Performance and Reliability    | Tools for load, stress and     | k6, JMeter,       |
| Testing Tools                  | reliability testing, to verify | Gatling, Apache   |
|                                | a system holds up under        | Bench, Artillery, |
|                                | expected and peak traffic.     | BlazeMeter        |
|--------------------------------|--------------------------------|-------------------|

When nothing is missing, the scan says so rather than printing an empty table:

Coverage 11/11 - all categories are covered.

The headline is bold on an interactive terminal. Colour is omitted when the output is piped or written with --output-file, and when NO_COLOR is set.

JSON Output

zanadir scan --dir . --output json

Sample Output:

[
  {
    "ID": "Performance Testing",
    "Name": "Performance and Reliability Testing Tools",
    "Description": "Tools for measuring code coverage to ensure testing completeness and software quality.",
    "Suggestions": [
      {
        "Name": "k6",
        "Repository": "https://github.com/grafana/k6",
        "Description": "Grafana k6 is an open-source, developer-friendly, and extensible load testing tool. k6 allows you to prevent performance issues and proactively improve reliability.",
        "Language": ""
      },
      {
        "Name": "JMeter",
        "Repository": "https://github.com/apache/jmeter",
        "Description": "An Apache project designed to load test functional behavior and measure performance, with support for various protocols and servers.",
        "Language": ""
      }
    ]
  }
]

SARIF Output

zanadir scan --dir . --output sarif

SARIF is the standard interchange format for static analysis results. Emitting it lets uncovered categories show up in GitHub's Security tab, and in any other SARIF-consuming platform, alongside your other scanners.

Each uncovered category becomes one SARIF rule and one result at warning level, with the suggested tools listed in the result's help text. Results are anchored at a CI configuration file — the place the missing tool would be added. A missing control is not a defect on a particular line, but every SARIF consumer expects a location, and GitHub code scanning rejects a report whose results have none.

Markdown Output

zanadir scan --dir . --output markdown

Markdown is the format for putting a scan in front of people rather than in a file. Tools link to their repositories, and the report opens with a hidden marker so a workflow can update the comment it posted last time instead of adding a new one on every push.

Sample Output:

<!-- zanadir-report -->
### zanadir

Coverage 10/11 - 1 category needs attention:

| Category | Description | Suggested tools |
| --- | --- | --- |
| Performance and Reliability Testing Tools | Tools for load, stress and reliability testing. | [k6](https://github.com/grafana/k6), [JMeter](https://github.com/apache/jmeter) |

When nothing is missing the table is omitted, leaving a single line.

Writing the report to a file

Use --output-file to write the report to a path instead of stdout. This works with every format, and is the reliable way to produce a machine-readable report: redirecting stdout captures the debug log as well, so --output sarif --debug > report.sarif yields a file that is not valid JSON.

zanadir scan --dir . --output sarif --output-file zanadir.sarif

To publish the report from a GitHub Actions workflow:

- name: Run zanadir
  run: zanadir scan --dir . --output sarif --output-file zanadir.sarif

- name: Upload SARIF
  uses: github/codeql-action/upload-sarif@v3
  with:
    sarif_file: zanadir.sarif

Uncovered categories then appear in the repository's Security tab alongside your other scanners.

Posting the report to a pull request

SARIF puts uncovered categories in the Security tab, which people visit occasionally. A pull request comment is where they already are.

permissions:
  contents: read
  pull-requests: write

steps:
  - name: Run zanadir
    run: zanadir scan --dir . --output markdown --output-file zanadir.md

  - name: Post the report
    run: gh pr comment "$NUMBER" --body-file zanadir.md --edit-last --create-if-none
    env:
      GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
      NUMBER: ${{ github.event.pull_request.number }}

--edit-last keeps one comment up to date instead of adding one per push. It matches on the last comment by the same user, so if something else comments as github-actions too, match the marker instead:

  - name: Find the previous report
    uses: peter-evans/find-comment@v4
    id: previous
    with:
      issue-number: ${{ github.event.pull_request.number }}
      body-includes: "<!-- zanadir-report -->"

  - name: Post the report
    uses: peter-evans/create-or-update-comment@v5
    with:
      comment-id: ${{ steps.previous.outputs.comment-id }}
      issue-number: ${{ github.event.pull_request.number }}
      body-path: zanadir.md
      edit-mode: replace

A pull request from a fork gets a read-only token, so the comment step cannot post. Guard it with if: github.event.pull_request.head.repo.full_name == github.repository rather than reaching for pull_request_target, which would run your workflow with write access to a fork's code.

Coverage Score

Every scan is summarised as a coverage score: the categories that apply to the repository, minus the ones still uncovered.

Three rules keep the number honest:

  • Excluded categories leave the denominator. A repository is not marked down for a category it has declared irrelevant with --excluded-categories.

  • So do categories with nothing to scan. A repository with no Terraform, Helm chart, Kubernetes manifest or Dockerfile is not told to add Checkov, and is scored out of ten rather than eleven. The scan says which:

    IaC Security is not applicable and is out of the score: nothing in this
    repository needs it.
    

    Two categories are ruled out this way. IaC Security needs infrastructure to scan, and the detection is deliberately broad — a directory called infra, k8s or charts is enough to keep it. Workflow Security needs GitHub Actions, because every tool in it reads that format, so a GitLab-only repository is not told to add actionlint.

    The rest apply to any codebase, and the ones that arguably do not — load testing a library, an SBOM for something that ships nothing — cannot be told apart from the ones that do, so guessing would rule out categories a repository does need.

  • Baseline-accepted gaps still count as uncovered. A baseline records that a gap is tolerated, not that it was closed. A score that rose because someone committed a file would measure nothing.

README Badge

--badge writes the score as a shields.io endpoint file:

zanadir scan --dir . --badge zanadir-badge.json
{
  "schemaVersion": 1,
  "label": "zanadir",
  "message": "10/11",
  "color": "green"
}

Publish that file from CI and point a badge at it. Put it on a branch of its own rather than committing it to the default branch: a protected default branch only takes changes through a pull request, so a workflow that pushes the badge there is rejected.

![zanadir](https://img.shields.io/endpoint?url=https://raw.githubusercontent.com/OWNER/REPO/badges/zanadir-badge.json)

A job that keeps it current on every push to the default branch, publishing to a badges branch it creates on the first run:

badge:
  if: github.event_name == 'push'
  runs-on: ubuntu-latest
  permissions:
    contents: write
  steps:
    - uses: actions/checkout@v4

    - name: Run zanadir
      run: zanadir scan --dir . --badge zanadir-badge.json

    - name: Publish the badge when it moved
      run: |
        set -euo pipefail
        cp zanadir-badge.json "$RUNNER_TEMP/zanadir-badge.json"
        rm -f zanadir-badge.json
        git config user.name github-actions
        git config user.email github-actions@github.com
        if git fetch --depth=1 origin badges 2>/dev/null; then
          git switch --discard-changes -C badges FETCH_HEAD
        else
          git switch --orphan badges
        fi
        cp "$RUNNER_TEMP/zanadir-badge.json" zanadir-badge.json
        git add zanadir-badge.json
        if git diff --cached --quiet; then exit 0; fi
        git commit -m "chore: update zanadir badge"
        git push origin badges

The badges branch holds that one file and nothing else. If a ruleset covers every branch rather than only the default one, exclude badges from it.

The colour tracks the score: green at 80% or above, yellow at 60%, orange at 40%, red below that, and bright green only at full coverage.

Effectiveness

Presence is not protection. A scanner wired up so it can never fail a build leaves a repository worse off than one with no scanner at all, because everybody believes the control is there. All of these used to report covered:

- uses: gitleaks/gitleaks-action@v2
  continue-on-error: true          # the job stays green whatever it finds
on:
  schedule: [{cron: "0 3 * * *"}]  # nothing is blocked at merge time
on:
  push: {branches: [main]}         # pull requests are never checked

A scan now grades each control it finds and reports the ones that protect less than their presence suggests:

3 covered categories are weakened:
  Linter is partial (.github/workflows/pushonly.yml)
  SCA is advisory (.github/workflows/nightly.yml)
  Secrets Detection is advisory (.github/workflows/ci.yml)
Verdict Meaning
enforcing the control can fail the build on the path that gates a change
partial it can fail a build, but not on that path - pushes only, say
advisory it runs, and cannot block anything
unknown the configuration cannot be read well enough to say

A weakened control does not fail a scan unless you ask it to. --enforce and --fail-on act only on categories with no tooling; --fail-on-weakened is what turns a weak control into a failure:

zanadir scan --dir . --fail-on-weakened
Enforcement failed: controls that cannot fail a build: Secrets Detection (advisory)

The two are independent. --enforce on its own still ignores weakened controls, so upgrading does not start failing builds that passed before. --fail-on narrows both.

A baseline accepts a weakness at the verdict it had when accepted:

version: 1
categories:
  - Performance Testing
weakened:
    Secrets Detection: partial

So accepting partial does not also accept it becoming advisory later. If the control gets worse than its recorded verdict, the scan fails again. --write-baseline records the verdicts for you.

Some of this is generic - continue-on-error defeats any control, and so does a workflow that only runs on a schedule. The rest is specific to one tool, and a rule can say so:

  - id: "tfsec-rule"
    regex: "(?i)\\btfsec\\b"
    weakenedWhen:
      - runMatches: "--soft-fail\\b"
        verdict: "advisory"
      - input: "soft_fail"
        equals: "true"
        verdict: "advisory"

A check is either a regex over the step's shell command or one action input compared to a value - deliberately not an expression language. Covered today: trivy --exit-code 0, gitleaks --exit-code 0, tfsec and checkov --soft-fail / soft_fail: true, and anchore/scan-action with fail-build: false.

Two deliberate silences. An if: condition is never interpreted, because it can reference arbitrary context and reading one wrong is worse than admitting it cannot be read - the control is reported unknown instead. And a category is judged by its strongest control, so one properly wired scanner keeps the category quiet however many weak ones sit beside it.

Controls declared outside the pipeline

Dependabot and Renovate are detected from their configuration - .github/dependabot.yml, renovate.json and the other names Renovate accepts - not from a CI job, because that is not where they live.

They are graded advisory. Both run on the forge's own schedule and open pull requests; neither can fail a build. So a repository whose only dependency control is Dependabot is reported as covered and weakened, which is a more useful answer than either "you have no SCA" or "you are covered":

1 covered category is weakened:
  SCA is advisory (.github/dependabot.yml)

Platform coverage

GitHub Actions is graded in full. GitLab CI is graded for the two signals that are unambiguous there - allow_failure: true, which is continue-on-error under another name, and when: manual, a job that only runs when somebody asks.

GitLab's rules:, only: and except: are deliberately not interpreted. Whether a branch pipeline gates a merge depends on a project setting that is not in the repository, so reading them would be guessing. A GitLab job with neither weakening field is reported unknown, which says nothing rather than something wrong. CircleCI has no equivalent signal and is not graded.

In SARIF a weakened control is a note, pointing at the file that produced the verdict, while a missing category stays a warning.

Language-Aware Suggestions

Zanadir detects which languages a repository uses and suggests only tools that apply to it — a Go project is not offered ESLint, and a JavaScript project is not offered Pylint. Tools that work regardless of ecosystem (Trivy, Gitleaks, Codecov, and so on) are always suggested.

Detection is based on dependency manifests in the repository root and its immediate subdirectories, so common monorepo layouts work:

Language Detected from
Go go.mod
Python requirements.txt, pyproject.toml, setup.py, Pipfile
JavaScript package.json
Ruby Gemfile, *.gemspec
Java pom.xml, build.gradle, build.gradle.kts
Rust Cargo.toml
PHP composer.json
C# *.csproj, *.sln

node_modules, vendor and other dependency directories are skipped, since their manifests describe code the project did not write. If no language is recognised, every tool is suggested, exactly as before.

Advanced Usage

Exclude Specific Categories

Skip certain categories during analysis:

zanadir scan --dir . --excluded-categories "SCA,Secrets Detection"

Category names must match the list above. An unrecognized name is rejected with an error rather than being silently ignored.

Enforce Mode

Zanadir provides an --enforce flag to ensure that all CI/CD suggestions are fulfilled. If any suggestion is not met, the CI pipeline will fail. This helps enforce security best practices and compliance in automated workflows.

zanadir scan --dir . --enforce

The category that failed the build is printed to stderr:

Enforcement failed: uncovered categories: SCA, Secrets Detection

Failing on Specific Categories

--enforce is all-or-nothing, which makes it hard to adopt on an existing repository: a single uncovered category fails every build. Use --fail-on to enforce only the categories you care about, while the rest stay informational:

zanadir scan --dir . --fail-on "SCA,Secrets Detection"

--fail-on implies enforcement, so --enforce is not needed alongside it. Category names are matched case-insensitively.

Baseline

A baseline records the gaps a repository knowingly accepts. Those categories are still reported, but they no longer fail a scan — so enforcement can be switched on before everything is fixed, and only new gaps break the build.

Generate one from the current state:

zanadir scan --dir . --write-baseline

This writes .zanadir-baseline.yaml (override with --baseline <path>) and exits successfully:

# zanadir baseline: categories that are uncovered but accepted.
# These are still reported; they just do not fail a scan.
# Regenerate with: zanadir scan --dir . --write-baseline
version: 1
categories:
    - Coverage
    - Performance Testing

Then enforce against it. The scan passes while the repository's gaps match the baseline, and fails as soon as a new one appears:

zanadir scan --dir . --enforce --baseline .zanadir-baseline.yaml

Commit the baseline so the accepted gaps are reviewable, and shrink it over time.

Debug Mode

Get detailed logging information:

zanadir scan --dir . --debug

Config File

--config (-c) reads flag values from a YAML file, so a team stops repeating them on every invocation. Each key is the name of the flag it sets:

# .zanadir.yml
excluded-categories: [Performance Testing]
enforce: true
fail-on-weakened: true
baseline: .zanadir-baseline.yaml
badge: zanadir-badge.json
output: markdown
zanadir scan --dir . -c .zanadir.yml
zanadir scan --dir . -c .zanadir.yml --output json   # the command line wins
  • A flag given on the command line overrides the same key in the file.
  • An unknown key is an error, so a misspelt exclude-categories fails the scan instead of silently scanning without the exclusion.
  • Relative paths (baseline, badge, output-file) are resolved against the directory holding the config file, not the directory you run from.
  • zanadir fix -c reads the same file and uses only excluded-categories and debug.
  • dir and write-baseline stay on the command line: one says what to scan, the other is a one-off action rather than a setting.

Custom Rules

zanadir only recognises the tools in its catalogue, so an in-house scanner reads as a missing category. Teach it with rules: in the config file, in the same shape as the built-in rules:

rules:
  - id: acme-scan
    applyOn: [Job.Run]          # Artifact.Name, Job.Name, Job.Package, Job.Run
    categories: [SAST]
    regex: '\bacme-scan\b'
    weakenedWhen:               # optional: configurations that cannot fail a build
      - runMatches: '--report-only'
        verdict: advisory       # advisory or partial

Custom rules add to the catalogue and never replace a built-in rule, so an id that is already taken is an error, as is a regex that does not compile or an unknown category. A rule that matches counts as coverage and is graded like any other, so --fail-on-weakened catches acme-scan --report-only too. zanadir fix uses the same rules to decide what is uncovered.

Complete Example

# Scan with all options
zanadir scan \
  --dir /path/to/repo \
  --output json \
  --excluded-categories "Linter" \
  --enforce \
  --debug

zanadir fix

A scan tells you what is missing. fix prints the configuration to add:

zanadir fix --dir .
Data Leakage & Secrets Detection is not covered. Add to .github/workflows/security.yml:

  - name: Detect secrets
    uses: gitleaks/gitleaks-action@v2
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

  https://github.com/gitleaks/gitleaks

It prints only; no file is touched. The CI platform is detected from the repository, and snippets are emitted for GitHub Actions or GitLab CI accordingly.

Not every suggested tool has a template. A category whose tools are all untemplated is skipped rather than emitting something half-right, so fix covers fewer categories than scan reports. Templates live in fixer/templates.yaml and pin actions to major tags; adding one is a self-contained contribution.

Generating a workflow

--write generates a standalone .github/workflows/zanadir-suggested.yml instead of printing:

zanadir fix --dir . --write
Wrote .github/workflows/zanadir-suggested.yml (9 categories).
It runs as its own job, so it repeats checkout and adds a check to pull requests.

Existing workflows are never edited, so nothing you wrote can be damaged; the worst case is a file you delete. Re-running overwrites the generated file and produces the same result, and zanadir refuses to overwrite a file at that path that it did not generate.

That standalone job is the trade-off: it repeats checkout and adds its own entry to the checks list, which is noisier than adding the steps to a job you already have. Move them into your own workflow whenever you prefer.

--write currently generates GitHub Actions only. On other platforms, run without it and paste the snippets.

--excluded-categories works as it does for scan.

Installation

You can install Zanadir using Go:

# Install directly from source
go install github.com/MustacheCase/zanadir@latest

Or using Homebrew:

# Install using Homebrew (custom tap)
brew tap --custom-remote MustacheCase/zanadir https://github.com/MustacheCase/zanadir.git
brew install mustachecase/zanadir/zanadir

The tap is this repository, so the formula lives in Formula/zanadir.rb.

GitHub Actions

If you're using GitHub Actions, you can use our Zanadir-based action to run CI\CD scans on your code during your CI workflows.

Contributors

Zanadir is still in its experimental phase. We are working hard to release the first stable version soon.
