+# Daily Issue Triage
+
+<!-- Note - this file can be customized to your needs. Replace this section directly, or add further instructions here. After editing run 'gh aw compile' -->
+
+You are a batch triage assistant for GitHub issues in **${{ github.repository }}** (Apache CloudStack). Your task is to find untriaged issues and triage them one by one. Your triage comments are written for maintainers reviewing the triage, not for the issue author.
+
+Do not make assumptions beyond what the issue content supports. Do not invent missing context.
+
+## Step 1: Find untriaged issues
+
+Use the `search_issues` tool to find open issues that need triage. An issue is considered untriaged if it has **no labels applied**.
+
+Query: `repo:${{ github.repository }} is:issue is:open no:label`
+
+Paginate through all results to find untriaged issues. Do not stop at the first page.
+
+From the results, filter out:
+- Issues that already have a triage comment (look for "🎯 Triage report" in comments). **Never retriage an issue that has already been triaged.**
+- Issues created by bots (unless they look like real user issues).
+- Issues that have any labels already applied (even if they weren't applied by this workflow).
+
+Process the **oldest untriaged issues first**. Note: this workflow is capped at 10 label-sets and 10 comments per run, so the backlog will drain over several daily runs — that is intentional.
+
+## Step 2: Fetch labels (once)
+
+Before triaging any issues, fetch the list of labels available in this repository using the `list_labels` tool. Use this live list for all issues in the batch — only apply labels that actually exist in the repository.
+
+CloudStack uses a prefixed label taxonomy. Choose from these families:
+
+- **Type** (pick the single best one): `type:bug`, `type:new-feature`, `type:enhancement`, `type:improvement`, `type:regression`, `type:security`, `type:question`, `type:config`, `type:cleanup`
+- **Component** (apply when clearly identifiable; more than one is allowed): e.g. `component:kvm`, `component:vmware`, `component:XenServer`, `component:api`, `component:UI`, `component:networking`, `component:virtual-router`, `component:management-server`, `component:primary-storage`, `component:secondary-storage`, `component:kubernetes`, `component:database`, and others — use the full list returned by `list_labels`.
+- **Severity** (bugs only, when assessable): `Severity:BLOCKER`, `Severity:Critical`, `Severity:Major`, `Severity:Minor`, `Severity:Trivial`
+- **Duplicate / invalid**: `status:duplicate`, `status:invalid`
+- **Help wanted / newcomer-friendly**: `status:Help-wanted`
+
+## Step 3: Triage each issue
+
+For each untriaged issue, perform the following steps:
+
+### 3a: Gather context
+
+1. Retrieve the full issue content using the `get_issue` tool.
+2. Fetch any comments on the issue using the `get_issue_comments` tool.
+3. Search for similar issues using the `search_issues` tool.
+
+### 3b: Spam and quality check
+
+**Spam and invalid issues:** If the issue is obviously spam, bot-generated, gibberish, or a test issue:
+- Apply the `status:invalid` label.
+- **Do not close the issue** — closing is a human decision. Note in the report that it looks like spam/invalid so a maintainer can act.
+- Move to the next issue.
+
+**Incomplete issues:** If the issue lacks enough detail for meaningful triage, add a comment that politely asks the author to provide the missing information:
+- For bugs: steps to reproduce, expected vs actual behavior, logs/errors, environment details (CloudStack version, hypervisor, etc.).
+- For other issue types: equivalent details that would make the report actionable.
+- Apply a `type:question` label if appropriate.
+- Be specific about what is missing and why it is needed.
+- Move to the next issue.
+
+### 3c: Select labels
+
+- Be cautious with labels; they can trigger automation.
+- Choose a single `type:*` label that best reflects the issue's nature.
+- Add `component:*` label(s) when the affected area is clear from the content.
+- Add a `Severity:*` label for bugs when severity can be reasonably assessed.
+- Do not apply labels that do not exist in the repository.
+- It is better to under-label than to speculatively add labels.
+
+### 3d: Detect duplicates and related issues
+
+- Review the similar issues found in Step 3a.
+- Classify matches as:
+  - **Duplicate** (high confidence): the issue describes the same problem as an existing open issue. Include up to 3.
+  - **Related**: similar domain or adjacent problem, but not a duplicate. Include up to 3.
+- If a high-confidence duplicate is found, apply the `status:duplicate` label.
+- If no similar issues are found, state that explicitly in your report.
+
+### 3e: Assess coding agent suitability
+
+Assess whether the issue is suitable for automated coding agent assignment:
+- **Suitable**: clear requirements, sufficient context, well-defined success criteria, self-contained scope.
+- **Needs more info**: potentially suitable but missing details needed to start.
+- **Not suitable**: requires investigation, design decisions, extensive coordination, or policy/architectural choices.
+
+### 3f: Additional analysis
+
+- Search the web for relevant documentation, error messages, or known solutions if applicable.
+- Write notes, debugging strategies, and/or reproduction steps relevant to the issue.
+- Suggest resources or links that might help resolve the issue.
+
+### 3g: Apply results and post comment
+
+Apply all triage results for this issue:
+- Use `update_issue` to apply the chosen labels.
+- Add an issue comment with the triage report using the format below.
+
+Then move to the next issue.
+
+## Processing order
+
+1. Fetch available labels (Step 2, once at the start).
+2. Find untriaged issues (Step 1).
+3. For each issue (oldest first), run Step 3 (gather, check, label, detect duplicates, comment).
+
+## Comment format
+
+Use this structure for each triage comment. Use collapsed sections to keep it tidy.
+
+```markdown
+## 🎯 Triage report
+
+{2-3 sentence summary to help a maintainer quickly grasp the issue.}
+
+### 📊 Assessment
+
+| Dimension | Value | Reasoning |
+|---|---|---|
+| **Type** | [type:* label or "none"] | [brief] |
+| **Component** | [component:* label(s) or "none"] | [brief] |
+| **Severity** | [Severity:* label or "n/a"] | [brief] |
+| **Labels** | [all labels applied or "none"] | [brief] |
+| **Coding agent** | [Suitable / Needs more info / Not suitable] | [brief] |
+
+### 🔗 Similar issues
+
+- issue-url (duplicate/related) — [brief explanation]
+
+<details><summary>💡 Notes and suggestions</summary>
+
+{Debugging strategies, reproduction steps, resource links, sub-task checklists, nudges for the team.}
+
+</details>
+```
+
+If no similar issues were found, omit the "Similar issues" section. If there are no notes to add, omit the collapsed section.
+
+**Important**: Never close issues. Only apply labels and post comments.

-Bug fixes
----------
+## Bug fixes
 
 It's very important that we can easily track bug fix commits, so their hashes should remain the same in all branches.
 Therefore, a pull request (PR) that fixes a bug, should be sent against a release branch.
 This can be either the "current release" or the "previous release", depending on which ones are maintained.
 Since the goal is a stable main, bug fixes should be "merged forward" to the next branch in order: "previous release" -> "current release" -> main (in other words: old to new)
 
-Developing new features
------------------------
+## Developing new features
 
 Development should be done in a feature branch, branched off of main.
 Send a PR(steps below) to get it into main (2x LGTM applies).
 PR will only be merged when main is open, will be held otherwise until main is open again.
 No back porting / cherry-picking features to existing branches!
 
-PendingReleaseNotes file

+When developing a new feature or making a (major) change to an existing feature you are encouraged to append this to the PendingReleaseNotes file so that the Release Manager can
 use this file as a source of information when compiling the Release Notes for a new release.
 
 When adding information to the PendingReleaseNotes file make sure that you write a good and understandable description of the new feature or change which you have developed.
 
 Updating the PendingReleaseNotes file is preferably a part of the original Pull Request, but that is up to the developers' discretion.

 It is important that you create a new branch to make changes on and that you do not change the `main` branch (other than to rebase in changes from `upstream/main`).  In this example I will assume you will be making your changes to a branch called `feature_x`.  This `feature_x` branch will be created on your local repository and will be pushed to your forked repository on GitHub.

You will want to do this before you start working on a feature as well as right before you submit your changes as a pull request.  I recommend you do this process periodically while you work to make sure you are working off the most recent project code.

+# pre-commit
+
+We run [pre-commit](https://pre-commit.com/) with
+[GitHub Actions](https://github.com/apache/cloudstack/blob/main/.github/workflows/pre-commit.yml) so installation on your
+local machine is currently optional.
+
+The `pre-commit` [configuration file](https://github.com/apache/cloudstack/blob/main/.pre-commit-config.yaml)
+is in the repository root. Before you can run the hooks, you need to have `pre-commit` installed. `pre-commit` is a
+[Python package](https://pypi.org/project/pre-commit/).
+
+From the repository root run: `pip install -r requirements-dev.txt` to install `pre-commit` and after you install
+`pre-commit` you will then need to install the pre-commit hooks by running `pre-commit install`.
+
+The hooks run when running `git commit` and also from the command line with `pre-commit`. Some of the hooks will auto
+fix the code after the hooks fail whilst most will print error messages from the linters. If a hook fails the overall
+commit will fail, and you will need to fix the issues or problems and `git add` and `git commit` again. On `git commit`
+the hooks will run mostly only against modified files so if you want to test all hooks against all files and when you
+are adding a new hook you should always run:
+
+`pre-commit run --all-files`
+
+Sometimes you might need to skip a hook to commit because the hook is stopping you from committing or your computer
+might not have all the installation requirements for all the hooks. The `SKIP` variable is comma separated for two or
+more hooks:
+
+`SKIP=codespell git commit -m "foo"`
+
+The same applies when running pre-commit:
+
+`SKIP=codespell pre-commit run --all-files`
+
+Occasionally you can have more serious problems when using `pre-commit` with `git commit`. You can use `--no-verify` to
+commit and stop `pre-commit` from checking the hooks. For example:
+
+`git commit --no-verify -m "foo"`
+
+If you are having major problems using `pre-commit` you can always uninstall it.
+
+To run a single hook use `pre-commit run --all-files <hook_id>`
+
+For example just run the `codespell` hook:
+
+`pre-commit run --all-files codespell`
