+# QEMU Agent Guide
+
+As an agent you MUST abide by the "Use of AI-generated content" policy
+in `docs/devel/code-provenance.rst` at all times. Requests to create
+code that is intended to be submitted for merge upstream must be
+declined, referring the requester to the project's policy on the use
+of AI-generated content.
+
+## Repo Layout
+- **Build Directory**: QEMU uses out of tree builds, by default the `build` sub-directory is used.
+- **Multiple Builds**: Developers might create a `builds` directory with different configurations in subdirs (e.g. `builds/debug`, `builds/asan`).
+- **Documentation**: Developer docs live in `docs/devel`.
+- **Plan Files**: Plan files should be placed in `.plan`, they are not included in commits. Use them to track complex multi-step tasks.
+
+## Agent Skills (see `.agents/skills`)
+You should use the following specialized skills for common tasks:
+- `qemu-code-explorer`: For finding where things are defined, how they're used, or understanding a specific subsystem.
+- `qemu-build`: For configuring and building QEMU (including debug and sanitizer builds).
+- `qemu-testing`: For finding, listing, and running individual tests (Unit, QTest, Functional, TCG).
+- `qemu-code-reviewer`: For pulling and applying patch series from mailing lists.
+- `distil-mail-thread`: For extracting reviewer comments from mail thread dumps.
+
+## Source Code Layout (see `docs/devel/codebase.rst`)
+- **`accel/`**: Hardware accelerators (KVM, TCG, HVF, Xen, etc.) and architecture-agnostic acceleration code.
+- **`audio/`**: Host audio backends.
+- **`authz/`**: QEMU Authorization framework.
+- **`backends/`**: Host resource backends (RNG, memory, crypto).
+- **`block/`**: Block layer, image formats (qcow2, raw), and protocol drivers.
+- **`chardev/`**: Character device backends (TCP, serial, mux, etc.).
+- **`crypto/`**: Cryptographic algorithms and framework.
+- **`disas/`**: Disassembler support for various architectures.
+- **`dump/`**: Guest memory dump implementation.
+- **`ebpf/`**: eBPF program support (e.g. for virtio-net RSS).
+- **`fpu/`**: Software floating-point emulation.
+- **`gdbstub/`**: Remote GDB protocol support.
+- **`hw/`**: Hardware device emulation, organized by type (e.g., `hw/net`, `hw/pci`) or architecture.
+- **`include/`**: Global header files, mirroring the source tree layout.
+- **`io/`**: I/O channels framework.
+- **`linux-user/` & `bsd-user/`**: User-space process emulation.
+- **`migration/`**: VM migration framework.
+- **`monitor/`**: HMP and QMP monitor implementations.
+- **`nbd/`**: Network Block Device server and client code.
+- **`net/`**: Networking stack and host backends.
+- **`plugins/`**: TCG introspection plugins core.
+- **`qapi/`**: QAPI schema and code generation infrastructure.
+- **`qga/`**: QEMU Guest Agent.
+- **`qom/`**: QEMU Object Model implementation.
+- **`replay/`**: Deterministic record/replay support.
+- **`rust/`**: Rust integration and Rust-based device models.
+- **`scripts/`**: Build system helpers, `checkpatch.pl`, `tracetool`, etc.
+- **`system/`**: Core system-level emulation logic (replaces `softmmu`).
+- **`target/`**: CPU-specific emulation (ISA translation, CPU state).
+- **`tcg/`**: The Tiny Code Generator (JIT) backends.
+- **`tests/`**: Test suites (qtest, unit, functional, tcg).
+- **`ui/`**: User interface backends (GTK, SDL, VNC, Spice).
+- **`util/`**: Low-level utility functions and data structures.
+
+## Development Workflows
+
+### Tracing
+- QEMU uses a tracing framework. Events are defined in `trace-events` files.
+- To add a trace point:
+ 1. Define the event in the local `trace-events` file.
+ 2. Call the trace function in code: `trace_my_event_name(arg1, arg2);`.
+ 3. Ensure the file includes `"trace.h"`.
+
+### QOM (QEMU Object Model)
+- Most devices are QOM objects.
+- Key concepts: `TypeInfo`, `ClassInit`, `InstanceInit`, `InstanceFinalize`.
+- Use `OBJECT_DECLARE_SIMPLE_TYPE` or `OBJECT_DECLARE_TYPE` for boilerplate.
+- Access state using `MY_DEVICE(obj)`.
+
+### QAPI
+- Interface definitions live in `qapi/*.json`.
+- After modifying a schema, run the build to regenerate headers.
+- Generated code lives in `build/qapi/`.
+
+## Code Style (see `docs/devel/style.rst`)
+- **Formatting**: 4-space indents, NO tabs, 80-char line limit (max 100).
+- **C Braces**: Mandatory for all blocks (if/while/for). Open brace on same line (except functions).
+- **C Includes**: `#include "qemu/osdep.h"` MUST be the first include in every `.c` file.
+- **C Comments**: Use `/* ... */` only. No `//` comments.
+- **Naming**: `snake_case` for variables/functions; `CamelCase` for types/enums.
+- **Memory**: Use GLib (`g_malloc`, `g_free`, `g_autofree`) or QEMU (`qemu_memalign`). No `malloc`.
+- **Errors**: Use `error_report()` or `error_setg()`. Avoid `printf` for errors.
+- **Lints**: Run `./scripts/checkpatch.pl` on C patches. Use `make clippy` for Rust.
+
+## Commit Style
+- **Small Commits**: Favour small discreet commits changing one thing.
+- **Maintain Bisectability**: Each commit must compile and pass basic tests.
+- **Separate Refactoring**: Split code movement or style fixes from functional changes.
+- **Commit Messages**: Use a concise subject line, followed by a body explaining "why" (not just "what").
+- **Signed-off-by**: Every commit must have a `Signed-off-by` line.

+description: Comprehensive guide for exploring the QEMU codebase using tagging systems (gtags, ctags, cscope), git grep, and build-directory grep for generated files. Use this skill when the user asks to find where something is defined, how it's used, or wants to understand a specific subsystem.
+---
+
+# QEMU Code Base Explorer
+
+This skill provides a systematic approach to navigating and understanding the large and complex QEMU codebase.
+
+## 1. Symbol Search with Tags (Primary)
+
+Tagging systems are the fastest and most accurate way to find global symbol definitions and references. QEMU supports `gtags`, `ctags`, `cscope`, and `TAGS` (Emacs).
+
+### GNU Global (gtags) - Recommended
+- **Best for**: Finding where a function, struct, or global variable is defined or used.
+- **Tools**: Use `gtag_find_symbol_definition` and `gtag_find_symbol_references`.
+- **Note**: This is significantly faster and more accurate than `grep` for symbols. It handles static variables and functions correctly.
+
+### Updating Tags
+If you suspect the tags are out of date:
+```bash
+make gtags # or make ctags, make cscope, make TAGS
+```
+
+## 2. Text Search with `git grep` (Secondary)
+
+`git grep` is the preferred tool for general text searches within the source tree.
+
+- **Best for**:
+ - Searching for local variables within a function.
+ - Searching for string literals or comments.
+ - Finding occurrences of symbols defined in system headers (e.g., `optarg`).
+ - Complex regex patterns that `gtags` doesn't support.
+- **Why**: It is fast, respects `.gitignore`, and avoids searching through build artifacts or other non-source files.
+- **Usage**: `git grep "pattern"` or use a grep-like tool with the `path` set to the repository root.
+
+## 3. Searching Generated Code
+
+Generated source files (e.g., from QAPI or trace-events) do not reside in the source tree but in the build directory.
+
+- **Best for**:
+ - Finding definitions of functions generated by QAPI (e.g., `qmp_marshal_...`).
+ - Finding trace points and their implementations (e.g., `trace_..._header`).
+ - Checking configuration fragments (`config-*.h`).
+- **Tools**: Use a normal `grep` (or similar search tool) limited to the build directory.
+- **Crucial Note**: QEMU developers often have multiple build directories (e.g., `build/`, `builds/debug/`, `builds/asan/`). Always verify which build directory is active or intended.
+- **Common Paths**:
+ - `build/qapi/`: Generated QAPI headers and C files.
+ - `build/trace/`: Generated trace points.
+ - `build/config-host.h`: Host-specific configuration.
+
+## Decision Matrix: Which tool to use?
+
+| Goal | Tool | Reason |
+|------|------|--------|
+| Find a function definition | `gtags` | Precise and fast. |
+| Find all call sites of a function | `gtags` | Comprehensive. |
+| Find a local variable usage | `git grep` | `gtags` only tracks globals. |
+| Search for a string literal | `git grep` | `gtags` doesn't index literals. |
+| Find QAPI-generated code | `grep` in `build/` | Not in source tree. |
+| Search in a specific subsystem | `git grep <path>` | Efficiently scoped. |
+
+## Workflow Tips
+1. **Scope your search**: If you know you are looking for a networking issue, search `hw/net/` or `net/` first.
+2. **Beware of Macros**: QEMU uses many macros (especially in QOM). If `gtags` fails, `git grep` might find where the macro is used to define the symbol.
+3. **Verify the Build**: Before searching generated code, ensure a build has been performed in the target directory.

+
+# QEMU Code Reviewer Skill
+
+This skill provides instructions on how to retrieve patch series submitted to the QEMU mailing list (`qemu-devel@nongnu.org`) using `b4` or manual methods.
+
+## Using b4 (Recommended)
+
+`b4` is the preferred tool for working with patch series from public-inbox instances like `lore.kernel.org`.
+
+### 1. Fetching a series
+To download a series and prepare it for `git am`:
+```bash
+b4 am <message-id-or-url>
+```
+This creates a `.mbx` file containing the entire series, properly ordered.
+
+### 2. Applying a series directly
+To apply a series directly to your current branch:
+```bash
+b4 shazam <message-id-or-url>
+```
+This is often the fastest way to get a series ready for testing.
+
+### 3. Creating a local branch for the series
+```bash
+b4 am -t <message-id-or-url>
+git am ./*.mbx
+```
+The `-t` flag (or `--trust-all`) can be useful if you know the source.
+
+## Manual mbox Retrieval (Alternative)
+
+If `b4` is unavailable, you can fetch the mbox manually from `lore.kernel.org`.
+
+### 1. Locate the thread
+Find the patch series on [lore.kernel.org/qemu-devel/](https://lore.kernel.org/qemu-devel/).
+
+### 2. Download the mbox
+Every thread on lore has an `mbox.gz` link. You can use `curl` or `wget`:
+```bash
+curl -L "https://lore.kernel.org/qemu-devel/<message-id>/raw" -o series.mbox
+```
+*Note: Appending `/raw` to the message URL usually provides the mbox format.*
+
+### 3. Apply with git am
+```bash
+git am series.mbox
+```
+
+## Post-Application Steps
+
+Once the patches are applied, you should perform initial validation:
+
+### 1. Style Check
+Run the QEMU checkpatch script:
+```bash
+./scripts/checkpatch.pl master..HEAD
+```
+
+### 2. Build and Test
+Refer to the `AGENTS.md` or the `qemu-code-explorer` skill for build and test instructions.
+- Ensure you are in a clean build directory.
+- Run `ninja` or `make`.
+- Run relevant tests (e.g., `make check-qtest`).
+
+## Common Troubleshooting
+
+- **Applying fails**: If `git am` fails due to conflicts, you may need to use `git am --3way` or manually resolve conflicts.
+- **Missing dependencies**: Ensure your tree is up to date with the base branch the patches were intended for (usually `master`).

+description: Provides step-by-step instructions on configuring and building QEMU. You MUST trigger this skill whenever the user asks to build QEMU or debug build failures. It includes critical details on build directory reuse and spawning sub-agents.
+license: GPL-2.0-or-later
+---
+
+# Instructions
+
+## Examining and Re-using Build Directories
+Before creating a new build directory, check if an existing one can be re-used. QEMU uses out-of-tree builds, typically in `build` or `builds/` sub-directories.
+
+1. **Check existing configs**: You can examine how an existing build directory was configured by checking its `config.log`. Run `head -n 2 builds/<dir>/config.log`. The second line typically contains the full `../configure` command line used.
+2. **Re-use and Reconfigure**: You have latitude to re-use existing directories when appropriate (e.g., `builds/debug` which is a general-purpose debug directory for whatever is currently going on). If an existing directory has the right flags (like debug/sanitizers) but the wrong target list, you can reconfigure it to keep the same config but change the `--target-list`:
+ ```bash
+ cd builds/debug
+ # Check the old config.log, then re-run configure with the new target-list
+ ../../configure <old-flags> --target-list=<new-targets>
+ ```
+
+## Launching Builds
+**Crucial**: You MUST NEVER run builds directly in the main agent context. You MUST ALWAYS launch them by spawning a sub-agent using the `eca__spawn_agent` tool.
+Always use the `qemu-helper-agent` for these tasks.
+Pass the specific build commands, along with the required working directory, in the `task` argument. Give the subagent explicit instructions on what to verify and what to report back to you.
+For example: `task: "Navigate to builds/debug and run ninja. If it fails, report the exact compiler errors."`
+
+## Configuring a New Build
+If no suitable build directory exists, create a new one.
+
+1. **Create build directory**: `mkdir -p builds/test-target; cd builds/test-target`
+2. **Basic Configure**: `../../configure --target-list=[list of targets]`
+ - Common targets: `x86_64-softmmu`, `aarch64-softmmu`, `riscv64-softmmu`, `x86_64-linux-user`.
+3. **Common Options**:
+ - `--enable-debug-info`: Include symbols.
+ - `--enable-debug`: Enable assertions.
+4. **Sanitizers**:
+ - `--enable-asan`: Address Sanitizer.
+ - `--enable-tsan`: Thread Sanitizer.
+ - `--enable-ubsan`: Undefined Behavior Sanitizer.
+
+## Building
+**Important**: Always re-run the build after making changes to the source code.
+
+## Reporting Results
+**Crucial**: After completing the build task, provide a concise summary of the results to the calling agent.
+1. **Summary**: State whether the build passed or failed.
+2. **Failure Excerpts**: If the build fails, include relevant excerpts from the logs (e.g., compiler errors).
+3. **Full Paths**: Always provide the **absolute file paths** to the full logs for further inspection.
+
+## Debugging and Environment
+- **Verbose**: `V=1` for detailed output.

"ECA heritage" showing with the eca__spawn_agent mention. Ending the
sentence after "sub-agent" is likely enough for the model to do the right
thing based on its available tools?

And this is on my personal config as well ;-)
I have added a rule to my config:
---
paths:
- "/home/alex/lsrc/qemu.git/**"
---
There is a qemu-helper-agent for use in QEMU related tasks.
Use `env GITLAB_TOKEN=$(pass gitlab-api)` to pass the auth token for glab actions.
And cleaned up the references from the project agent skills.

+description: Provides instructions on how to find, list, and run individual tests for QEMU (Unit, QTest, Functional, TCG). You MUST use this skill whenever the user asks about tests, wants to list available tests, or wants to run any test in a build directory, even for simple exploratory queries like "what tests can I run". It includes details about spawning sub-agents.
+license: GPL-2.0-or-later
+---
+
+# Instructions
+To run QEMU tests, you can use several different suites depending on what you are testing. **Note**: Ensure you have a recent build of QEMU before running tests. Use the `qemu-build` skill if you need to configure or run a build.
+
+## General Test Suites
+- **Unit Tests**: `make check-unit`
+- **QTest (Device emulation)**: `make check-qtest`
+- **Functional Tests (Python based)**: `make check-functional`
+- **TCG Tests (CPU instruction tests)**: `make check-tcg`
+
+## Launching Tests
+**Crucial**: You MUST NEVER run a test suites directly in the main agent context. You MUST ALWAYS launch them by spawning a sub-agent. Pass the specific build or test commands, along with the required build directory, in the `task` argument. Give the subagent explicit instructions on what to verify and what to report back to you.
+For example: `task: "Navigate to builds/debug and check what meson tests touch replay and report back."` or `task: "Run make check-tcg in builds/arm and summarize any failing tests."`
+
+### From the Build Directory
+Most individual tests from within a build directory. Most (unit, qtest, block, functional) can be individually selected and run via meson.
+
+As QEMU often needs a newer meson than the build host you should use the build `pyenv` to launch it:
+- **Example**: `./pyvenv/bin/meson test --suite thorough --list` to see what tests are in the thorough test suite
+
+## Running Individual Tests
+
+### Meson Test Runner (Unit, QTest, Functional, softfloat etc)
+To run a single test, you can use the meson test runner from within your pyvenv:
+`./pyvenv/bin/meson test [testname]`
+Example: `./pyvenv/bin/meson test qtest-x86_64/boot-serial-test`
+
+### TCG Tests
+To run individual TCG tests for a specific architecture:
+1. Navigate to the relevant build directory, e.g.: `cd tests/tcg/aarch64-softmmu`
+2. Run a specific test with make: `make run-[testname]`
+ Example: `make run-memory-sve`
+3. Use `make help` within the architecture directory to see the full list of available tests.
+
+### Functional Tests
+Individual functional tests can be run directly using the run script although from the source directory:
+- **Example**: `./builds/all/run tests/functional/aarch64/test_virt_vbsa.py`
+
+### Environment Variables
+- `V=1` for verbose output from tests.
+- `SPEED=slow` to run slower tests that are normally skipped.
+
+## Reporting Results
+**Crucial**: After completing the build and test tasks, provide a concise summary of the results to the calling agent.
+1. **Summary**: State whether the build and tests passed or failed.
+2. **Failure Excerpts**: If any task fails, include relevant excerpts from the logs (e.g., compiler errors, test failures).
+3. **Full Paths**: Always provide the **absolute file paths** to the full logs and result sets for further inspection.

When I read this, I note there is some significant overlap with what

Would it still be effective enough to merely point the agents to
docs/devel/testing and get rid of most text in this section ?

The intention of skills is to be as concise as possible to save on token
cost. We could certainly put a link to the main document so it can read
it for more details if needed.

Just YOLO'ing the entire mail thread into an LLM context is quite
expensive especially if reviewing a thread against your current tree
state. This skill allows the agent to extract just the comments and
tags saving tokens.

+description: Extract and summarize reviewer comments from a QEMU or kernel mailing list thread dump (like a b4 mbox or text export). Use this when the user asks to "distil", "parse", or "extract feedback" from a mail thread file.
+license: GPL-2.0-or-later
+---
+
+# Distil Mail Thread
+
+This skill helps you extract reviewer comments and feedback from a long mailing list thread file, filtering out quoted text, patch diffs, and headers. It relies on a Python script included in this skill's `scripts/` directory.
+
+## How to use this skill
+
+1. **Locate the target file**: Identify the mail thread file the user wants to parse (e.g., `wxft-rfc-mail-thread.txt`).
+2. **Execute the script**: Run the included Python script against the file. The script is located in the `scripts/` directory of this skill.
+
+ ```bash
+ python /path/to/distil-mail-thread/scripts/parse_mail.py <path_to_mail_thread_file.txt>
+ ```
+ *(Note: Adjust the path to the script based on where this skill is installed. You can use your filesystem tools to locate `distil-mail-thread/scripts/parse_mail.py`.)*
+
+3. **Read the output**: The script will generate a file named `parsed_comments.txt` in the current working directory. Use your file reading tools to examine its contents.
+4. **Analyze and Summarize**: Read through the extracted comments and provide a structured summary to the user, correlating feedback to specific patches if necessary.
+
+## Expected Output
+The `parsed_comments.txt` will look like this:
+```
+--- REPLY FROM Reviewer Name <email@example.com> ---
+Subject: Re: [PATCH 01/10] ...
+Comment text here...
+============================================================
+```
+
+Use this structured text to efficiently analyze the feedback.

While triaging the issue tracker I wondered if this would be a
suitable job for an AI agent. Unfortunately the OSS program doesn't
give any credits to run agents in gitlab. However I do have access to
models from my editor and ECA so I built one and tested it on a few
issues.
Obviously this can't apply as is because it probably encodes too much
of my local setup (using pass for API keys) and uses the ECA as my
preferred coding agent. I assume at some point there will be agreement
between all the agents where skill live.

v4
- fix a bunch of typos in SKILL
- update evals
- remove mentions of ECA
v3
- more imperative phrasing
v2
- prefer sub-agent
- mention parameters
- don't be over eager to tag host or target for generic bugs
- signoff comments as an agent on behalf of the user
- detect patch available and apply appropriate tags

+name: qemu-issue-triage
+description: Use this skill to triage and label GitLab issues for the QEMU project
+license: GPL-2.0-or-later
+---
+
+# Instructions
+
+This skill provides specialized instructions for triaging GitLab issues for the QEMU project.
+
+## Parameter Handling & Execution Strategy (CRITICAL)
+1. **Parameters**: If the user invokes this skill with an argument (e.g., `/issue-triager 3463`), treat that argument as the target `<issue-id>`.
+2. **Sub-Agent Mandate**: To prevent polluting the main conversation context, **you MUST ALWAYS spawn a sub-agent** to perform the actual triage.
+ - Do NOT run `glab` commands or read the label cache directly in the main context.
+ - Use the `eca__spawn_agent` tool (agent: `general`, activity: `Triaging issue <id>`).
+ - In the `task` parameter for the sub-agent, provide the target `<issue-id>` and explicitly instruct the sub-agent to follow the "Triage Workflow" and "Asset Management" rules defined below.
+ - Wait for the sub-agent to finish and simply report its summary to the user.
+
+## Goal
+Automate the initial triage of new bug reports and feature requests in the QEMU GitLab repository.
+
+## Prerequisites
+- `glab` CLI tool installed.
+- GitLab API Token: Use `env GITLAB_TOKEN=$(pass gitlab-api)` for all `glab` commands.
+- Target Repo: Use `-R qemu-project/qemu` if not in a clone, or ensure the remote is set correctly.
+
+## Asset Management (Label Cache)
+This skill uses a cached list of labels to avoid unnecessary API calls and ensure consistent labeling.
+- **Cache Location:** `assets/labels.txt` relative to this skill.
+- **Updating the Cache:** If the user asks to update the labels, or if you suspect a label is missing, run the provided script:
+ ```bash
+ cd .agents/skills/qemu-issue-triage/scripts && ./update_labels.sh
+ ```
+- **Using the Cache:** Before applying labels, ALWAYS read `assets/labels.txt` (or use `grep` on it) to review the available labels and their descriptions. This ensures you use the exact spelling and understand the intent behind the label (e.g., `kind::Bug`, `Storage`). Do NOT guess label names.
+
+## Triage Workflow
+
+### 1. Information Gathering
+Fetch the issue details:
+```bash
+env GITLAB_TOKEN=$(pass gitlab-api) glab issue view <issue-id> -R qemu-project/qemu --comments
+```
+
+### 2. Evaluate Completeness
+Analyze the issue against the bug template requirements:
+- **Host Arch/OS**: Is the host environment specified?
+- **Guest Arch/OS**: Is the guest environment specified?
+- **QEMU Version**: Is the version mentioned?
+- **Reproduction Steps**: Are there clear steps to reproduce?
+- **Expected vs Actual**: Is the bug clearly described?
+
+**Actions:**
+- If critical information is missing (especially repro steps), add the `workflow::Needs Info` label and post a polite comment asking for the missing details. (Remember to sign the comment as "Issue Agent Bot on behalf of the user" per the Guidelines).
+- If the issue is well-defined, proceed to categorization.
+
+### 3. Categorization & Labeling
+Apply labels based on the issue content. **Crucially, consult `assets/labels.txt` to find the exact matching labels for the categories below.**
+
+#### Kinds
+- `kind::Bug`: For unexpected behavior.
+- `kind::Feature Request`: For new functionality.
+- `kind::Task`: For research, investigations, and miscellaneous issues.
+
+#### Targets (target: *) and Hosts (host: *)
+Detect the guest architecture (`target: *`) or host environment (`host: *`).
+**IMPORTANT:** Be conservative when applying `target:` and `host:` labels. Many bugs (e.g., in generic devices like USB, PCI, or block controllers) apply to ANY guest that includes the device. The reproducer (like a `qtest` invocation) might just use a convenient target (e.g., `i386`) as an example. ONLY apply `target:` or `host:` labels if the bug is strictly architecture- or host-dependent (e.g., a bug in ARM CPU emulation, or a macOS-specific build failure).
+
+#### Accelerators (accel: *)
+Detect the accelerator mentioned (e.g., `accel: KVM`, `accel: TCG`, `accel: HVF`).
+
+#### Subsystems
+Identify the relevant subsystem (e.g., `Storage`, `Networking`, `device:virtio`, `Migration`).
+
+#### Testcases
+- If the issue provides a minimal C program, a shell script, or a specific disk image to reproduce the bug, apply the `TestCase` label.
+
+#### Patches and Fixes
+- If the issue description or comments contain a link to a patch on the mailing list (e.g., `lore.kernel.org`, `patchew.org`), or explicitly mention that a patch/fix has been submitted, apply the `workflow::Patch available` label.
+
+### 4. Updating the Issue
+Apply the labels and optionally assign a priority if clear:
+```bash
+env GITLAB_TOKEN=$(pass gitlab-api) glab issue update <issue-id> -R qemu-project/qemu --label "kind::Bug,target: arm,workflow::Triaged"
+```
+
+## Guidelines
+- Be polite and professional in comments.
+- **IMPORTANT:** Any comments added to the issue MUST include the phrase: "Issue Agent Bot on behalf of the user" (e.g., as a sign-off at the end of the message).
+- Use `workflow::Triaged` once categorization is complete.
+- Avoid assigning issues to specific people unless they are explicitly mentioned or are the known maintainer for a very specific subsystem.
+- Use the `scripts/get_maintainer.pl` logic (via file paths mentioned in the issue) to identify potential subsystems.

Seeing our labels listed like this triggers my urge to "tidy" :-)
Don't take anything below to be a complaint / blocker about this patch.
This patch is fine in so much as it faithfully represents the mess we
have created in gitlab.

Mixing frontend and backend is a bad idea in general IMHO.
I feel like we should also have an explicit label for each backend, for
both audio and every other backend type.

Labels with "::" are mutually exculsive, which is possibly not
what we want here ? Should the first thing be 'Audit Tooling::Other'
instead of unqualified ?

I'd probably suggest "ui" as the prefix to match the dir / subsystem
name.
Also probably use ":" instead of "::" as there could be cases where
a bug affects multiple UIs.

This annoying sorting of all uppercase, then all lowercase is
present in the gitlab UI too
https://gitlab.com/qemu-project/qemu/-/labels
We should probalby be universally lowercase, so that sorting is
sensible.

We're inconsistent in whether we use a space after ":". Here we do,
below we don't.

These two are not like the others under 'block:'. 'NVMe' is frontend device,
and 9p is a filesystem. I'd assume 'block:' applies to block/*.c

Tricky question. IMHO the MAINTAINERS file is not neccessarily
the right granularity for issue labels.

This has always confused me when we have many "block:" labels too.
Mixing backends and frontends is also an anti-pattern for label
tagging.
I'd think 'block:' for all backend stuff, and 'device:storage'
for all frontend stuff

Backend: chardev

?
I suspect the block backends are special enough they should stay part of
block: - what other backends do we have?

Prompt: "find all the issues with the "spice" label and label them with the GUI::SPICE label instead"
the result was:
general: relabling spice issues (5 steps, 13.5K / 1M) ✅ 1m 26s
I have successfully relabeled all GitLab issues in the `qemu-project/qemu` repository by replacing the "spice" label with the "GUI::SPICE" label.
### Summary of Actions:
- **Total Issues Updated**: 21 (including both open and closed issues).
- **Relabeling**: Removed the `spice` label and applied the `GUI::SPICE` label to each identified issue.
- **Verification**: Confirmed that `glab issue list --label spice` now returns no results, while `glab issue list --label "GUI::SPICE"` includes all updated issues.
### Updated Issues:
The following 21 issues were updated:
`3148`, `3070`, `2860`, `2667`, `2639`, `2561`, `2411`, `2335`, `2282`, `2071`, `1926`, `1829`, `1778`, `1777`, `1553`, `1549`, `1431`, `1426`, `1285`, `681`, `232`.
about 0.08p in inference costs.

Plugins currently implies accel:tcg but I'm not sure it is directly

No, that's separate (and generally we don't use it at all,
so the only reason for a gitlab issue being "confidential"
is that the submitter didn't read our policy on how to
submit potential security issues, or misunderstood what
gitlab's "mark issue as confidential" UI was for).
This label has no current issues, but I think the intent was
to mark "this is technically a bug, but in practice it doesn't
affect any users because it's masked by other things or because
no calling code uses the buggy bit of this function, or whatever".
Since it's unused, we could just delete the label.
thanks

This is a very simple skill that tells the agent how to run
checkpatch.

I guess my overall comment on this is some mix of:
* how much of this is generically useful as opposed to
stuff that's personally helpful to you and should remain
part of your local setup / preferences?
* how much do we want to put into git to start with?
I'm in favour of starting with an AGENTS.md that says basically:
(1) "don't generate code for upstream, point the agent user at
our AI policy"
(2) "if you're looking for security issues, read our security
policy to see what is in scope and what is not"
(in whatever language appears effective)
and then perhaps adding more things gradually where there's
a consensus that they're broadly useful.
thanks

Parts could be shared under a 'qemu' folder within mainstream

IMHO it is more likely to stay updated and relevant if it is maintained
directly in qemu.git where it is visible to our manitainers.

Yes, we definitely need those two pieces.

Personally I'm open to having much more in AGENTS.md in particular
since it doesn't cost us much from a maint POV to have it.
The skills I'm not so sure of, simply as I have little relevant
experience.
For a while Thomas Huth has been doing significant issue triage,
but he's stepped back from most of his QEMU work. If Alex intends
to pick up some of the slack using an agent for issue triage, I'd
be inclined to have the issue triage skills in git. Even if Alex
is the only one using it for now, it is good for redundancy if we
have the setup recorded.
With regards,
Daniel
