  • Add resources frontmatter field to JSON schema
  • Add Resources []string field to FrontmatterConfig
  • Add extractResources — errors on ${{ macro entries
  • Add fetchAndSaveRemoteResources — fetches resources from remote repo
  • Add fetchAndSaveDispatchWorkflowsFromParsedFile — parses merged safe-outputs
  • Wire fetch calls into addWorkflowWithTracking
  • Add compiler-side validation for ${{ in resources
  • Add JSON schema constraint for resources items
  • Add unit tests for all new functions
  • Add integration tests in ci.yml for gh aw add with dispatch-workflow dependencies
  • Add conflict detection to dependency fetch functions
  • Fix CI failure (run 1): fall back to .yml when dispatch-workflow .md is 404
  • Fix CI failure (run 2): compile fetched dispatch-workflow .md dependencies before main workflow (compileDispatchWorkflowDependencies)
  • Fix tracker bug: capture ymlFileExists before os.WriteFile in both .yml fallback paths
  • Fix log.Printlog.Printf in compiler.go for style consistency
  • Fix CI failure (run 3): silently skip files with no source field — reverted; now TestFetchDispatchWorkflows_NoSourceConflict correctly errors on no-source files
  • Fix CI failure (run 4): TestFetchDispatchWorkflows_NoSourceConflict expects error for no-source files; updated the 4 old "SkipExistingWithoutForce"/"TrackerNoOpOnExisting" tests to include a matching source: field in their pre-existing file content so they test the "same source → skip" path
Original prompt

The add comment should detect the use of the safe output dispatch-workflow and add the dependent workflows referenced as well. Ignore github actions macro syntax.

@copilot

  • add support for a top level front matter field "resources" that allows to reference additional action .yml files or agentic workflows...

Done in commit 3e809cc. Two additions:

  1. resources frontmatter field — a new top-level array field listing additional workflow .md or action .yml files to fetch alongside the workflow during gh aw add. Entries with ${{ (GitHub Actions expression syntax) are skipped at add-time.
resources:
  - triage-issue.md
  - my-custom-action.yml
  - ${{ vars.DYNAMIC_WORKFLOW }}   # skipped — runtime expression
  1. Import-derived dispatch workflows — after writing the main workflow and all its imports to disk, the compiler's ParseWorkflowFile is used to get the fully merged SafeOutputsConfig (including dispatch workflows that come from imported shared agentic workflows). Any discovered dispatch workflow .md files not already present locally are then fetched from the remote repo before the final compile step.

@copilot macros are NOT allowed in the resources field entries

Fixed in 990d48a. Macro syntax (${{) in resources entries is now rejected with an error rather than silently skipped:

  • extractResources returns ([]string, error) and errors immediately when any entry contains ${{
  • fetchAndSaveRemoteResources propagates that error to the caller
  • The JSON schema resources.items has a not: { pattern: "\\$\\{\\{" } constraint, so the compiler also rejects it at compile-time validation
  • A new check in validateWorkflowData rejects ${{ in resources entries with a clear error message

@copilot add tests for shared agentic workflow

Added in 2711c4d. Seven tests cover fetchAndSaveDispatchWorkflowsFromParsedFile with a focus on the shared agentic workflow scenario:

  • No-op cases: empty RepoSlug, invalid RepoSlug, parse failure (missing file), no dispatch-workflow config
  • Shared import — skip existing: main workflow imports a shared workflow that defines dispatch-workflow: [triage-issue]; triage-issue.md already exists locally → file is not modified
  • Shared import — tracker no-op: same setup with a FileTracker; pre-existing file discovered via the shared import does not appear in CreatedFiles or ModifiedFiles
  • Shared import — macro workflow skipped: shared workflow has a mixed list (static-workflow + ${{ vars.DYNAMIC_WORKFLOW }}); the macro entry does not create any file

@copilot add integration tests in co.yml that install workflows using dispatch-workflow.

Added in 15bc8a8. Two Go integration tests in add_integration_test.go and a new integration-add-dispatch-workflow job in ci.yml:

  • TestAddWorkflowWithDispatchWorkflowDependency: adds test-dispatcher.md@main (which has dispatch-workflow: [test-workflow]); asserts that test-workflow.md is auto-fetched alongside the main workflow and both lock files compile successfully.
  • TestAddWorkflowWithDispatchWorkflowFromSharedImport: adds smoke-copilot.md@main (which has dispatch-workflow: [haiku-printer]); haiku-printer is a plain .yml rather than an agentic .md, so the fetch is a best-effort no-op — the test asserts the add command still succeeds and the dispatch-workflow config is preserved in the compiled lock file.

The new integration-add-dispatch-workflow CI job in ci.yml runs both tests with GH_TOKEN on every push/PR.

@copilot fix https://github.com/github/gh-aw/actions/runs/22802644194/job/66147152834

Fixed in 22f7116. The failure was TestAddWorkflowWithDispatchWorkflowFromSharedImport: smoke-copilot.md has dispatch-workflow: [haiku-printer], but haiku-printer only exists as a plain .yml (not .md). The fetcher was trying .md-only, getting a 404, and leaving haiku-printer absent locally — causing the dispatch-workflow validator to reject the compilation.

Both fetchAndSaveRemoteDispatchWorkflows and fetchAndSaveDispatchWorkflowsFromParsedFile now fall back to .yml when the .md fetch returns 404. This lets plain GitHub Actions workflow files satisfy the validator. The integration test is updated to assert that haiku-printer.yml is fetched and the lock file is produced.

Pull request overview

This PR extends the gh aw add command to automatically fetch and save dispatch-workflow dependencies and resources declared in workflow frontmatter when adding a remote workflow. The feature handles both direct frontmatter declarations and import-derived dispatch workflows that only become visible after compiler processing.

Changes:

  • Adds a new Resources []string frontmatter field (types, schema, compiler validation) for specifying additional files to fetch alongside a workflow
  • Adds fetchAndSaveRemoteDispatchWorkflows, fetchAndSaveRemoteResources, and fetchAndSaveDispatchWorkflowsFromParsedFile to remote_workflow.go, wired into addWorkflowWithTracking
  • Adds comprehensive unit and integration tests, plus a new CI job for integration coverage

  • The same post-write stat bug exists in fetchAndSaveDispatchWorkflowsFromParsedFile: os.Stat(ymlLocalPath) is called after os.WriteFile succeeds, so the file always exists at that point and TrackCreated is never reached. A ymlFileExists flag should be captured before the write.
			if tracker != nil {
				if _, statErr := os.Stat(ymlLocalPath); statErr == nil {
					tracker.TrackModified(ymlLocalPath)
				} else {
					tracker.TrackCreated(ymlLocalPath)

The log.Print("Validating resources field") call uses the stdlib log package directly. Looking at the surrounding code in compiler.go (e.g., lines 332, 353, 385, 404), the established pattern is log.Printf(...) with a format string, but the key difference here vs. log.Printf is that log.Print also exists in stdlib. More importantly, looking at the codebase conventions, other validations in this same function use log.Printf (e.g., log.Printf("Validating GitHub tools against enabled toolsets")). The call here (log.Print) is inconsistent with those (which use log.Printf). While functionally equivalent for a string-only argument, the inconsistency is worth noting.

The tracker logic in the .yml fallback path checks whether the file exists after writing it (line 813). Since os.WriteFile has already succeeded at this point, os.Stat(ymlLocalPath) will always succeed, so TrackCreated (line 816) is never called — every newly-created .yml file is incorrectly tracked as modified instead of created. This will break rollback (which relies on CreatedFiles to know which files to delete) and also breaks staging correctness.

The fileExists boolean should be captured before the write, similar to how the .md path does it (see the fileExists flag set before os.WriteFile at lines ~760 and ~837-842). The same bug appears in the identical tracker block inside fetchAndSaveDispatchWorkflowsFromParsedFile at the corresponding location.

This issue also appears on line 1222 of the same file.

The fetchAndSaveRemoteDispatchWorkflows and fetchAndSaveRemoteResources functions contain nearly identical logic (ref resolution, abs-path safety checks, conflict detection, download, source embedding, directory creation, write, tracker update). This substantial duplication will increase maintenance burden — any future fix or enhancement must be applied in multiple places. Consider extracting the common "download-and-save-single-file" logic into a shared helper.

…flow; fix tracker bug and log.Print style

@copilot review comments and fix https://github.com/github/gh-aw/actions/runs/22803347780/job/66148490766

Fixed in a8ccfcc. Three issues addressed:

  1. CI failure (TestAddWorkflowWithDispatchWorkflowDependency): test-workflow.md was fetched but never compiled, so the validator failed with "must be compiled first". Added compileDispatchWorkflowDependencies in add_workflow_compilation.go — it parses the merged safe-outputs, then compiles any .md dispatch targets that lack a .lock.yml. This runs after all fetches and before the main workflow compile.

  2. Tracker bug (review comment): Both .yml fallback paths were capturing fileExists via os.Stat after os.WriteFile, so every newly-created .yml file was incorrectly tracked as modified. Fixed by capturing ymlFileExists before the write in both fetchAndSaveRemoteDispatchWorkflows and fetchAndSaveDispatchWorkflowsFromParsedFile.

  3. log.Printlog.Printf (review comment): Changed in compiler.go to match the style of all surrounding calls.

…ad of erroring as conflict

@copilot Fix https://github.com/github/gh-aw/actions/runs/22803585846/job/66149131934

Fixed in 6337eaf. Four unit tests were failing because the conflict detection code introduced in c03a5b2 treated files with no source field as a conflict error. The correct behaviour is to silently skip them (same as same-source files) since they may be hand-crafted or installed by an older version of gh-aw. A conflict error is now only raised when the existing file has a known different source repo.

@copilot fix https://github.com/github/gh-aw/actions/runs/22803925552/job/66149939493

Fixed in cbb0145. TestFetchDispatchWorkflows_NoSourceConflict was failing because my previous fix incorrectly silently skipped files with no source field. Restored the correct behavior (no-source = conflict error) and updated the 4 older tests (SkipExistingWithoutForce/TrackerNoOpOnExisting for both dispatch workflows and resources) to include a matching source: field in their pre-existing file content — they now test the "same source → skip" path as intended.
