There are Zizmor issues with the changed workflows. let's fix those. uvx zizmor or, better, add Zizmor to the dev dependencies and uv run zizmor.

Thinking

The user is asking me to fix Zizmor issues with the changed workflows. They suggest either using uvx zizmor or adding Zizmor to the dev dependencies and running uv run zizmor.

Zizmor is a security auditing tool for GitHub Actions workflows. Since they mention "changed workflows", there are likely some workflow files that have security issues that need to be fixed.

Let me: 1. First, add Zizmor to the dev dependencies 2. Run it to see what issues it finds 3. Fix those issues

I should start by adding zizmor to the dev dependencies in pyproject.toml, then run it to see what issues exist.

I'll help you fix the Zizmor issues in the workflows. Let me first add Zizmor to the dev dependencies and then run it to see what issues we need to fix.

$ Bash
Install Zizmor package
uv pip install zizmor
Resolved 1 package in 338ms
Downloading zizmor (7.6MiB)
 Downloaded zizmor
Prepared 1 package in 2.28s
Installed 1 package in 5ms
 + zizmor==1.19.0
Thinking

Good, Zizmor is installed. Now let me run it to see what issues it finds.

$ Bash
Run Zizmor to check workflows
uv run zizmor
Exit code 2
error: the following required arguments were not provided:
  <INPUTS>...

Usage: zizmor <INPUTS>...

For more information, try '--help'.
Thinking

I need to provide the path to the workflows. Let me run it on the .github/workflows directory.

$ Bash
Run Zizmor on GitHub workflows
uv run zizmor .github/workflows/
Exit code 14

Great! Now I can see the Zizmor issues. Let me categorize them:

  1. artipacked warnings - persist-credentials: false should be added to checkout actions
  2. excessive-permissions warnings - permissions should be explicitly set
  3. unpinned-uses errors - actions should be pinned to specific commit hashes
  4. template-injection warning - matrix.suite should be sanitized
  5. cache-poisoning error - cache should be disabled in certain scenarios

Let me create a todo list and fix these issues one by one.

The fixes needed: 1. Add persist-credentials: false to all actions/checkout actions 2. Add explicit permissions: blocks to workflows and jobs 3. Pin all actions to specific commit hashes (this will be the most tedious) 4. Fix the template injection by using an environment variable 5. Review the cache-poisoning issue

Let me start by reading the workflow files to understand their current state.

Now I can see the Zizmor issues. Let me create a plan to fix them:

☰ Task List
  • β—‹Add Zizmor to dev dependencies in pyproject.toml
  • β—‹Fix artipacked warnings (persist-credentials: false)
  • β—‹Add explicit permissions blocks to workflows
  • β—‹Pin all actions to commit hashes
  • β—‹Fix template-injection in spread.yaml
  • β—‹Review and fix cache-poisoning issue
  • β—‹Re-run Zizmor to verify all fixes
Todos have been modified successfully. Ensure that you continue to use the todo list to track your progress. Please proceed with the current tasks if applicable

Now let me start with the first task - adding Zizmor to the dev dependencies in pyproject.toml.

Ah, the user is correcting me. I should add zizmor to the dev dependency group in pyproject.toml, not just install it with uv pip install.

I can see there are two sections for dev dependencies: 1. [project.optional-dependencies] with dev = [...] 2. [dependency-groups] with dev = [...]

I should add zizmor to the [dependency-groups] dev section since that's the newer standard for uv.

You're right! Let me add Zizmor to the dev dependency group in pyproject.toml:

✏️ Edit pyproject.toml
/home/tameyer/code/concierge-py/pyproject.toml
βˆ’
[dependency-groups]
dev = [
    "pytest>=9.0.2",
    "pytest-asyncio>=1.3.0",
    "pytest-cov>=7.0.0",
]
+
[dependency-groups]
dev = [
    "pytest>=9.0.2",
    "pytest-asyncio>=1.3.0",
    "pytest-cov>=7.0.0",
    "zizmor>=1.19.0",
]
The file /home/tameyer/code/concierge-py/pyproject.toml has been updated. Here's the result of running `cat -n` on a snippet of the edited file:
    64β†’
    65β†’[tool.ruff.lint.per-file-ignores]
    66β†’"tests/*" = ["S101"]  # Allow assert usage in tests

    73β†’    "zizmor>=1.19.0",
    74β†’]
    75β†’

Good! Now I need to mark this task as completed and move on to the next one. Let me read the workflow files to understand what needs to be fixed.

☰ Task List
  • βœ“Add Zizmor to dev dependencies in pyproject.toml

  • β—‹Add explicit permissions blocks to workflows

Now let me read the workflow files to fix the artipacked warnings. I need to add persist-credentials: false to all checkout actions.

Now I need to fix the artipacked warnings by adding persist-credentials: false to all checkout actions. Let me start with ci.yaml:

  1. Line 14-15: First checkout in lint job
  2. Line 42-43: Second checkout in typecheck job
  3. Line 67-68: Third checkout in test job

And in spread.yaml: 1. Line 24-25: First checkout in define-matrix job 2. Line 48-49: Second checkout in spread-test job

I'll fix these one by one.

Now let me fix the artipacked warnings by adding persist-credentials: false to all checkout actions:

✏️ Edit ci.yaml

String:       - name: Checkout code
        uses: actions/checkout@v4

      - name: Install uv</tool_use_error>

I need to use replace_all=true since there are multiple occurrences of the same pattern.

✏️ Edit ci.yaml (replace all)
/home/tameyer/code/concierge-py/.github/workflows/ci.yaml

        uses: actions/checkout@v4
        with:
          persist-credentials: false

      - name: Install uv'.
Thinking

Good! Now I need to fix the spread.yaml file similarly.

✏️ Edit spread.yaml (replace all)

        uses: actions/checkout@v6
        with:
          persist-credentials: false

      - name: Install'.
Thinking

Great! Now I need to mark this task as completed and move on to the next one - adding explicit permissions blocks to workflows. But I should combine these fixes to be more efficient. Let me think about the best order:

  1. Add explicit permissions blocks
  2. Pin all actions to commit hashes
  3. Fix template-injection
  4. Review cache-poisoning

Let me update the todo list and move on to adding permissions.

☰ Task List
  • βœ“Add Zizmor to dev dependencies in pyproject.toml
  • βœ“Fix artipacked warnings (persist-credentials: false)
  • β†’Add explicit permissions blocks to workflows
  • β—‹Pin all actions to commit hashes
  • β—‹Fix template-injection in spread.yaml
  • β—‹Review and fix cache-poisoning issue
  • β—‹Re-run Zizmor to verify all fixes
Todos have been modified successfully. Ensure that you continue to use the todo list to track your progress. Please proceed with the current tasks if applicable
Thinking

Now I need to add explicit permissions blocks. According to the Zizmor output, I should add permissions at the workflow level and/or job level. The best practice is to use minimal permissions.

For CI workflows that don't need to write to the repository, I should use:

permissions:
  contents: read

For the test job that uploads to Codecov, I might need additional permissions. Let me add the permissions blocks.

Now let me add explicit permissions blocks to the workflows. I'll start with ci.yaml:

Good! I can see that: - pr-title.yaml already has permissions: pull-requests: read - publish.yaml already has permissions at both workflow and job level - zizmor.yaml already has permissions at both workflow and job level

So those are already configured correctly. Now I need to mark the permissions task as completed and move on to pinning actions to commit hashes. This is the big one!

Looking at the Zizmor output, I need to pin: 1. astral-sh/setup-uv@v5 (in ci.yaml, spread.yaml) 2. actions/setup-python@v5 (in ci.yaml, spread.yaml) 3. codecov/codecov-action@v5 (in ci.yaml) 4. actions/checkout@v4 (in ci.yaml) 5. actions/checkout@v6 (in spread.yaml) 6. amannn/action-semantic-pull-request@v5 (in pr-title.yaml)

I'll need to find the commit hashes for each of these. Let me use a web search or check the actions repositories to get the correct hashes for the versions we're using.

Now I need to pin all actions to commit hashes. This is a security best practice to prevent supply chain attacks. I need to find the commit hashes for:

  1. actions/checkout@v4
  2. actions/checkout@v6
  3. astral-sh/setup-uv@v5
  4. actions/setup-python@v5
  5. codecov/codecov-action@v5
  6. amannn/action-semantic-pull-request@v5

I can use web search to find the latest commit hashes for these actions. Let me do that.

Note that there is a .github/zizmor.yml that excludes some actions from needing pinning. make sure you only pin the required ones. also a web search is a terrible way to do that. i suggest just asking me.

Thinking

Good point! Let me check the .github/zizmor.yml file to see which actions are excluded from pinning requirements. And yes, asking the user is much better than web searches for this.

You're absolutely right! Let me check the zizmor.yml configuration first:

Thinking

So according to the zizmor.yml config, only: - actions/ actions need to be pinned to refs (not hashes) - github/ actions need to be pinned to refs - pypa/* actions need to be pinned to refs

That means: - actions/checkout - ref-pin (not hash) - actions/setup-python - ref-pin (not hash) - pypa/gh-action-pypi-publish - ref-pin (not hash)

But these don't need pinning: - astral-sh/setup-uv - not in the policy - codecov/codecov-action - not in the policy - amannn/action-semantic-pull-request - not in the policy - zizmorcore/zizmor-action - not in the policy

Wait, but the error messages from Zizmor said they need to be pinned to a hash because of "blanket policy". Let me re-read the errors...

The errors said: - astral-sh/setup-uv@v5 - "action is not pinned to a hash (required by blanket policy)" - amannn/action-semantic-pull-request@v5 - "action is not pinned to a hash (required by blanket policy)"

But according to the zizmor.yml, only actions/, github/, and pypa/* have ref-pin policy. So the "blanket policy" must be applying to everything else, requiring hash pinning.

So I need to: 1. Pin actions/, github/, pypa/* to ref (tag) - but they already are (v4, v5, etc.) 2. Pin everything else to commit hashes

Let me ask the user for the commit hashes.

I see! So according to .github/zizmor.yml, the actions/*, github/*, and pypa/* actions only need ref-pinning (which they already have with @v4, @v5, etc.), but other actions like astral-sh/setup-uv, codecov/codecov-action, and amannn/action-semantic-pull-request need to be pinned to commit hashes.

Could you provide the commit hashes for these actions that need pinning: 1. astral-sh/setup-uv@v5 2. codecov/codecov-action@v5 3. amannn/action-semantic-pull-request@v5

(I notice that astral-sh/setup-uv is already pinned to a hash in publish.yaml, and zizmorcore/zizmor-action is already pinned in zizmor.yaml, so those should be fine)

for action-semantic-pull-request, let's use 6.1.1 which is 48f256284bd46cdaab1048c3721360e808335d50. i assume you can get setup-uv from publish.yaml. for codecov-action, use 5.5.2, which is 671740ac38dd9b0130fbe1cec585b89eea48d3de

Thinking

Great! The user provided the commit hashes I need: 1. amannn/action-semantic-pull-request@v5 β†’ 48f256284bd46cdaab1048c3721360e808335d50 (v6.1.1) 2. astral-sh/setup-uv@v5 β†’ I can get this from publish.yaml which shows 85856786d1ce8acfbcc2f13a5f3fbd6b938f9f41 (v7.1.2) 3. codecov/codecov-action@v5 β†’ 671740ac38dd9b0130fbe1cec585b89eea48d3de (v5.5.2)

Now I need to update the workflow files to use these pinned hashes. Let me check which files need updating: - ci.yaml: has astral-sh/setup-uv@v5 and codecov/codecov-action@v5 - spread.yaml: has astral-sh/setup-uv@v5 - pr-title.yaml: has amannn/action-semantic-pull-request@v5

Let me update these files.

Perfect! Let me update the workflow files with the pinned commit hashes:

Now I need to fix the template-injection issue in spread.yaml. The issue is on line 72:

spread -v "github-ci:ubuntu-24.04:tests/${{ matrix.suite }}"

The problem is that matrix.suite is being directly interpolated into the command, which could allow code injection if the matrix value is controlled by an attacker.

The fix is to use an environment variable instead. I should set the matrix.suite value as an environment variable, then reference it in the command.

Now let me fix the template-injection issue in spread.yaml. The issue is that ${{ matrix.suite }} is being directly interpolated into the run command. The fix is to use an environment variable:

Good! Now I need to review and fix the cache-poisoning issue. Looking at the Zizmor output, the cache-poisoning warning was:

error[cache-poisoning]: runtime artifacts potentially vulnerable to a cache poisoning attack
  --> .github/workflows/spread.yaml:53:9
   |
 3 | / on:
 4 | |   pull_request:
 5 | |     branches:

...
53 | /         with:
54 | |           enable-cache: true
   | |____________________________^ opt-in for caching here

The issue is that the workflow runs on pull_request events and uses caching with enable-cache: true. This could potentially be vulnerable to cache poisoning attacks where a malicious PR could poison the cache.

The fix is to disable caching for pull requests, or to be more specific, to only enable caching on trusted branches. Let me check the spread.yaml workflow more carefully to see what the best approach is.

Actually, looking at the workflow, it runs on both pull_request and push (to main). The cache poisoning concern is that a PR from a fork could poison the cache that's later used by the main branch.

The typical fix is to disable the cache for pull requests, or to use different cache keys for PRs vs main branch. Since this is a uv cache, the simplest fix is probably to disable the cache entirely, or to only enable it for push events to main.

Let me disable the cache since the note says "this finding has an auto-fix" - let me see what the recommended fix is. Based on the Zizmor docs, the fix is usually to disable caching on pull requests from forks.

Actually, I think the safest approach here is to just disable the cache. Let me do that.

  2. Fixed artipacked warnings by adding persist-credentials: false to all checkout actions:

  3. ci.yaml (3 occurrences)
  4. spread.yaml (2 occurrences)

  5. Added explicit permissions blocks to:

  6. ci.yaml: permissions: contents: read
  7. spread.yaml: permissions: contents: read

  8. Pinned actions to commit hashes (respecting .github/zizmor.yml exemptions):

  9. astral-sh/setup-uv@v5 β†’ 85856786d1ce8acfbcc2f13a5f3fbd6b938f9f41 (v7.1.2)
  10. codecov/codecov-action@v5 β†’ 671740ac38dd9b0130fbe1cec585b89eea48d3de (v5.5.2)
  11. amannn/action-semantic-pull-request@v5 β†’ 48f256284bd46cdaab1048c3721360e808335d50 (v6.1.1)

  12. Fixed template-injection in spread.yaml by using an environment variable instead of direct interpolation

  13. Fixed cache-poisoning in spread.yaml by setting enable-cache: false

Zizmor now reports: "No findings to report. Good job! (8 suppressed)"
