Skill: Fix GitHub Issue
You are to fix the GitHub issue indicated by the user.
Read first:
@AGENTS.md
Writing Style For GitHub Comments
Be terse. Every sentence must add information.
- No preamble, filler, or generic investigation language.
- Do not repeat the issue body.
- Link or name relevant files instead of narrating obvious code.
- Keep progress comments short and update one comment in place when running from
automation.
Research
Use gh to fetch the issue. Read enough source to identify the relevant
function, helper chain, plugin, or GUI path.
Before coding, run a duplicate-work preflight:
gh pr list --state open --search "<issue-id or keyword>"
gh issue list --state open --search "<keyword>"
If overlapping work exists, do not open a parallel implementation. Comment with
what you found and either hand off to the existing work or scope your fix to a
non-overlapping follow-up.
Post one comment with these sections before implementing:
# Research
<2-3 sentences explaining the root cause or missing behavior.>
**Relevant code**
- `path/to/file.m#Lx-Ly` - short annotation
# Proposed Fix
<One short paragraph explaining the smallest fix and focused validation.>
For larger feature or design work, do not guess. Write a concise design note in
the issue instead of opening a PR immediately. Include the problem, approach,
affected files, tests, tradeoffs, and open questions.
Implementation
- Create a branch named
agent/{YYYYMMDD}-fix-{issue-id}.
- Reproduce the issue with a focused MATLAB or Octave command when possible.
- Add a regression test or reproducibility command when practical. EEGLAB has no
single central test suite, so prefer a minimal scriptable command using
sample_data/ or plugin-local tests.
- Make the smallest local MATLAB change.
- Preserve
pop_* GUI, command-line, and history behavior.
- Keep EEG structure fields consistent and validate with
eeg_checkset.
Testing
Use the narrowest relevant validation first:
matlab -batch "cd('/path/to/eeglab'); eeglab('nogui'); <focused commands>"
octave --quiet --eval "cd('/path/to/eeglab'); eeglab('nogui'); <focused commands>"
Run plugin tests when relevant, for example:
matlab -batch "cd('/path/to/eeglab/plugins/ICLabel'); run_tests"
Do not weaken assertions or change expected numerical behavior without proving
the old expectation was wrong.
Uploading
When validation is complete, open a PR following
.agents/skills/pull-request/SKILL.md exactly. Attach it to the issue with a
short comment summarizing the fix and the validation command.
Verify CI Status
After opening the PR, monitor checks:
gh pr view <number> --json statusCheckRollup
Fix actionable failures before considering the task complete.
Tasks
Rules
Never credit yourself or AI tools in commits, comments, or PR descriptions.
