Fix codegen-agentic-fix workflow lock file out of sync

[Copilot]

The codegen-agentic-fix agentic workflow was broken because its .md frontmatter used invalid safe-output configuration, causing gh aw compile to fail and leaving the .lock.yml stale.

Before the change?

• The .github/workflows/codegen-agentic-fix.md frontmatter used underscored safe-output names (push_to_pull_request_branch, add_comment) and an invalid max field, which caused gh aw compile to fail
• The .lock.yml was stale and out of sync with the .md source, breaking the workflow at runtime
• The copilot-setup-steps.yml referenced an outdated gh-aw version (v0.42.17) inconsistent with the compiler version used to generate the lock file
• No guardrails existed in copilot-instructions.md to prevent this class of bug from recurring

After the change?

• Fix safe-output property names: push_to_pull_request_branch → push-to-pull-request-branch, add_comment → add-comment (gh-aw requires kebab-case)
• Remove invalid max field from push-to-pull-request-branch — not a valid property for that safe-output type (valid: branch, commit-title-suffix, github-token, if-no-changes, labels, target, title-prefix)
• Regenerate .lock.yml via gh aw compile codegen-agentic-fix using v0.68.3
• Update gh-aw version in copilot-setup-steps.yml from v0.42.17 to v0.68.3 to match the compiler version used to generate the lock file
• Add rules to .github/copilot-instructions.md in the "Boundaries and Restrictions → What NOT to Modify" section to prevent future lock file staleness:
  • Always run gh aw compile <workflow-name> after editing any .github/workflows/*.md agentic workflow source file
  • Never edit .github/workflows/*.lock.yml directly — these are auto-generated by gh aw compile

Pull request checklist

• Tests for the changes have been added (for bug fixes / features)
• Docs have been reviewed and added / updated if needed (for bug fixes / features)
• mvn spotless:apply has been run to format the code
• mvn clean verify passes locally

Does this introduce a breaking change?

• Yes
• No

Add a rule to copilot-instructions.md in the "Boundaries and Restrictions → What NOT to Modify" section (after the existing "DO NOT" rules) that prevents future lock file staleness. Add these two rules:

- **YOU MUST ALWAYS** run `gh aw compile <workflow-name>` after editing any `.github/workflows/*.md` agentic workflow source file to regenerate the corresponding `.lock.yml`. The lock file contains a content hash of the frontmatter — any edit to the `.md` without recompiling will cause the workflow to fail at runtime with a "lock file out of sync" error.
- **DO NOT** edit `.github/workflows/*.lock.yml` directly — these are auto-generated by `gh aw compile` from the `.md` source files.

This prevents the exact class of bug this PR is fixing: commit 9c80cc9 edited codegen-agentic-fix.md without recompiling the lock file, which broke the workflow and caused issue #129.

Added both rules to the "What NOT to Modify" section in copilot-instructions.md in commit fa1ff66.

Reviewed the PR. All changes look correct and complete:

• Safe-output names properly converted to kebab-case in both the .md source and lock file
• Invalid max field removed from push-to-pull-request-branch
• Lock file regenerated with updated frontmatter hash (e3ba3ae6)
• copilot-setup-steps.yml updated to use gh-aw v0.68.3 (matching the compiler version used)
• Two new guardrail rules added to copilot-instructions.md

The PR is ready to merge.

Pull request overview

This PR repairs the codegen-agentic-fix agentic workflow by bringing its .md frontmatter and compiled .lock.yml back into sync, updating the gh-aw tooling version used in setup, and adding repository guidance intended to prevent future lock-file drift.

Changes:

• Fixes codegen-agentic-fix.md frontmatter safe-outputs configuration (kebab-case keys; removes invalid fields).
• Regenerates codegen-agentic-fix.lock.yml using gh-aw v0.68.3.
• Updates .github/workflows/copilot-setup-steps.yml to install gh-aw v0.68.3 and adds guardrails to .github/copilot-instructions.md.

Copilot's findings

Comments suppressed due to low confidence (1)

.github/workflows/codegen-agentic-fix.md:215

• Same tool-name mismatch as above: the compiled workflow exposes push_to_pull_request_branch, but this line refers to push-to-pull-request-branch. Align the instruction with the actual safe-output tool name shown in the <safe-output-tools> section of the prompt.

Then call the `push-to-pull-request-branch` tool to push your commits to the PR branch.

[Copilot]

The workflow prompt lists the safe-output tool as push_to_pull_request_branch (snake_case), but these instructions tell the agent to use push-to-pull-request-branch (kebab-case). That mismatch will likely cause the agent to attempt a non-existent tool call at runtime. Update the text here (and the follow-up sentence below) to reference the actual tool name exposed in the prompt.

This issue also appears on line 215 of the same file.

[Copilot]

The compiled safe-output tool name is add_comment (snake_case), but this instruction says add-comment (kebab-case). This will confuse the agent and can lead to an invalid tool invocation. Update the prompt text to use the tool name shown in the prompt's safe-output tools list.

This new rule claims that any edit to an agentic workflow .md without recompiling will cause a runtime "lock file out of sync" error, but the generated lock files themselves state that "Not all edits will cause changes to this file" and the metadata records only a frontmatter_hash. Please narrow/reword this guidance to reflect what actually triggers out-of-sync (e.g., frontmatter/tooling changes) so we don’t encode incorrect instructions for future contributors.

Suggested change

- **YOU MUST ALWAYS** run `gh aw compile <workflow-name>` after editing any `.github/workflows/*.md` agentic workflow source file to regenerate the corresponding `.lock.yml`. The lock file contains a content hash of the frontmatter — any edit to the `.md` without recompiling will cause the workflow to fail at runtime with a "lock file out of sync" error.

- When editing a `.github/workflows/*.md` agentic workflow source file, run `gh aw compile <workflow-name>` if the change affects the compiled workflow or lock-file inputs (for example, frontmatter, tooling, or other compilation-relevant metadata) so the corresponding `.lock.yml` stays in sync. Not every markdown edit changes the lock file, so avoid claiming that any `.md` edit without recompiling will always fail at runtime.
