Support wildcard suffix matching for `slash_command` by Copilot · Pull Request #40369 · github/gh-aw

Copilot · 2026-06-19T17:56:29Z

This updates slash_command to accept a trailing *, enabling prefix-based matching so one workflow can handle a family of related command names. The change applies consistently to both decentralized command checks and centralized command routing.

Trigger semantics
- slash_command.name now supports a wildcard suffix.
- A config like smoke* matches commands such as smoke-copilot and smoke-copilot-sdk.
- The workflow receives the actual matched command name, not the wildcard pattern.
Decentralized matching
- Updated pre-activation command checks to treat * as a prefix matcher instead of an exact literal.
- Preserved existing exact-match behavior for non-wildcard commands.
Centralized routing
- Updated the centralized router to resolve routes by wildcard prefix as well as exact name.
- Routing now dispatches using the concrete matched command so downstream workflow context stays precise.
Shared runtime handling
- Added a shared slash-command matcher used by routing, pre-activation validation, and command neutralization.
- This keeps wildcard behavior aligned across compile-time conditions and JS runtime helpers.
Schema and docs surface
- Extended schema validation to allow a trailing * in command names and documented the new behavior in field descriptions.

Example:

on:
  slash_command:
    name: smoke*
    strategy: centralized

With that configuration, comments like these would match the same workflow:

/smoke-copilot
/smoke-copilot-sdk run tests

Pull request overview

This PR extends on.slash_command to support a trailing * wildcard suffix for prefix-based matching, and wires that behavior through both decentralized activation checks (compiled if: conditions) and centralized routing/JS runtime helpers so a single workflow can handle a family of related command names.

Changes:

Added wildcard-aware slash-command matching in the Go workflow condition builder (startsWith("/<prefix>") for name: prefix*).
Introduced a shared JS matcher module and updated routing, command-position validation, and command neutralization to use it.
Updated the workflow schema patterns/descriptions and added tests covering wildcard matching across Go + JS paths.

File	Description
pkg/workflow/command.go	Adds wildcard-suffix detection and emits `startsWith` conditions for wildcard command names.
pkg/workflow/command_precision_test.go	Adds coverage ensuring wildcard slash commands compile to prefix checks.
pkg/parser/schemas/main_workflow_schema.json	Allows an optional trailing `*` in slash command names and documents wildcard behavior.
actions/setup/js/slash_command_matcher.cjs	New shared JS helper for parsing and matching exact vs wildcard command names.
actions/setup/js/sanitize_content.test.cjs	Adds a test ensuring wildcard-configured commands are neutralized correctly.
actions/setup/js/sanitize_content_core.cjs	Uses the shared matcher to neutralize the actual matched command name (including wildcard matches).
actions/setup/js/route_slash_command.test.cjs	Adds tests for dot-containing commands and wildcard routing dispatch behavior.
actions/setup/js/route_slash_command.cjs	Switches routing to shared parsing/matching and resolves routes by wildcard prefix as well as exact name.
actions/setup/js/check_command_position.test.cjs	Adds tests for wildcard matching in both workflow_dispatch aw_context and comment bodies.
actions/setup/js/check_command_position.cjs	Updates command-position validation to use shared parsing/matching for wildcard support.

@copilot Investigate why reviewers were unable to create safe-outputs.

https://github.com/github/gh-aw/actions/runs/27841406528/job/82402381056

Root cause was a runtime packaging gap in actions/setup/setup.sh: sanitize_content_core.cjs now requires ./slash_command_matcher.cjs, but that file was not included in SAFE_OUTPUTS_FILES, so the safe-outputs MCP server failed to start (Cannot find module './slash_command_matcher.cjs').

Fixed in commit f7bf6c5 by adding slash_command_matcher.cjs to SAFE_OUTPUTS_FILES.

@copilot fix test https://github.com/github/gh-aw/actions/runs/27844995118/job/82412161598?pr=40369

Fixed in 0995042. I tightened slash-command parsing to require whitespace/end after the command (so punctuation-suffixed tokens no longer match) and updated/addded JS tests accordingly.

Add slash_command wildcard suffix support
