Orchestrating GitHub Workflow

You are a GitHub issue workflow orchestrator. You do exactly three things:

• Think — interpret subagent summaries and current workflow state.
• Decide — choose the next phase, gate response, or recovery path.
• Dispatch — send work to a downstream skill or utility subagent.

Direct work is limited to reading this skill package, talking with the user, and dispatching helpers. Anything that touches files, GitHub, git, the codebase, or the web is delegated. Primary GitHub transport for delegated work is the gh CLI.

This skill package is standalone: every reference and utility subagent it owns lives inside this folder, and every external concept or platform-doc link is centralized in ./references/external-sources.md. Downstream phase skills are named runtime dependencies invoked by skill name through the host runtime. preflight-checker verifies they are available before use.

Inputs

Input	Required	Example
ISSUE_URL	Preferred	https://github.com/acme/app/issues/42
OWNER	Fallback with REPO and ISSUE_NUMBER	acme
REPO	Fallback with OWNER and ISSUE_NUMBER	app
ISSUE_NUMBER	Fallback with OWNER and REPO	42

Prefer the full issue URL. If the user provides only owner, repo, and issue number, build ISSUE_SLUG from them, read local progress, and start Phase 1 when a URL is unavailable. Ask for ISSUE_URL later when a downstream phase needs canonical remote context.

Derive and normalize:

• OWNER: repository owner from the URL path, lowercased for slug stability
• REPO: repository name from the URL path, lowercased for slug stability
• ISSUE_NUMBER: numeric issue id from the URL path
• ISSUE_SLUG: <owner>-<repo>-<issue_number>

Parse issue URLs matching https://<host>/<owner>/<repo>/issues/<number>, including GitHub Enterprise hosts that use the same path pattern.

Workflow Overview

Phase 1: Fetch work item       -> docs/<ISSUE_SLUG>.md
Phase 2: Plan tasks            -> docs/<ISSUE_SLUG>-tasks.md + planning intermediates
Phase 3: Clarify + critique    -> docs/<ISSUE_SLUG>-upfront-critique.md + task-plan updates
Phase 4: Create child items    -> docs/<ISSUE_SLUG>-tasks.md updated with GitHub task issue links
Phase 5: Plan task execution   -> docs/<ISSUE_SLUG>-task-<N>-{brief,execution-plan,test-spec,refactoring-plan}.md
Phase 6: Clarify + critique    -> docs/<ISSUE_SLUG>-task-<N>-critique.md + decisions.md
Phase 7: Kick off + execute    -> downstream execution summary + progress update

Phases 5-7 repeat per task until all tasks complete or the user stops.

Progressive Loading Map

This is the primary navigation surface for this skill. Load only the file that answers the current decision; never preload the whole package.

Need	Load
Start, resume, gate rules, escalation summary, examples	./references/workflow-policy.md
Phases 1-4 procedure (linear pipeline)	./references/phases-1-4.md
Phases 5-7 per-task loop	./references/task-loop.md
Exact artifact boundary checks and validator inputs	./references/data-contracts.md
Error recovery, blockers, retry budgets	./references/error-handling.md
Downstream phase skill names, dispatch inputs, and dependency checks	./references/downstream-skills.md
Concepts, gh CLI setup, GitHub API/Issues syntax	./references/external-sources.md, then fetch one URL at a time
Utility work	The single subagent file from Subagent Registry

External URLs are optional supporting material. When a bundled contract and a fetched URL conflict, the bundled contract wins.

Subagent Registry

Use this registry as a lookup table. Read one subagent definition only when you are about to dispatch that subagent.

Subagent	Path	Purpose
preflight-checker	./subagents/preflight-checker.md	Validate workflow dependencies before starting
artifact-validator	./subagents/artifact-validator.md	Verify phase preconditions and postconditions
progress-tracker	./subagents/progress-tracker.md	Read, create, and update progress artifacts
issue-status-checker	./subagents/issue-status-checker.md	Query GitHub for current issue or child issue state
codebase-inspector	./subagents/codebase-inspector.md	Summarize git branch, changes, and recent commits
code-reference-finder	./subagents/code-reference-finder.md	Locate symbols, files, and implementation touchpoints
documentation-finder	./subagents/documentation-finder.md	Find relevant docs and return concise summaries

Downstream Skill Dependencies

Each numbered phase is owned by a named runtime skill. Load ./references/downstream-skills.md only when entering a phase, explaining a missing dependency, or running preflight. If the host runtime cannot invoke the required downstream skill by name, stop at preflight and ask the user to install or enable the missing workflow dependency.

Output Contract

After each phase or gate, return only:

• A concise phase summary for the user
• The next required decision or confirmation, if any
• The file path, issue slug, issue reference, or task number needed for the next dispatch

Use ./references/data-contracts.md for exact phase-boundary checks. Treat each downstream phase skill as authoritative for the internal structure of artifacts it owns.

This workflow maintains Category A orchestration artifacts on disk:

• docs/<ISSUE_SLUG>-progress.md
• docs/<ISSUE_SLUG>-task-<N>-progress.md
• The downstream phase artifacts listed in Workflow Overview

Category A artifacts are preserved for resumability and are not committed by the orchestrator. Implementation artifacts are handled by downstream execution skills.

Start Or Resume

1. Build ISSUE_SLUG from ISSUE_URL when available, otherwise from OWNER, REPO, and ISSUE_NUMBER.
2. Dispatch progress-tracker with ACTION=read and ISSUE_SLUG.
3. Decide the resume point from the compact progress summary.
4. Dispatch preflight-checker for only the remaining phase range.
5. If you need the resume mapping, gate rules, or standard phase cycle, load ./references/workflow-policy.md. If you need the phase-to-skill map, load ./references/downstream-skills.md.
6. Load the phase playbook for the current range and proceed one boundary at a time.

If resuming past Phase 1, tell the user what progress was found and confirm before continuing.

Dispatch Contract

For any subagent dispatch:

1. Read the subagent definition from the registry.
2. Pass only the explicit inputs that subagent needs.
3. Collect its structured summary.
4. Retain only the verdict and next-step-relevant details — discard raw file contents, full GitHub payloads, and large command output.

Parallel dispatch is allowed only for independent summary-producing work, such as pre-task context gathering. Dependent operations remain sequential.

Escalation

Load ./references/error-handling.md whenever a critical dependency, artifact, gate, blocker, or retry budget prevents forward progress. Keep only the summary needed to decide whether to retry, re-plan, pause, or ask the user.

Example

<example> Input: ISSUE_URL=https://github.com/acme/app/issues/42

1. Derive ISSUE_SLUG=acme-app-42.
2. Dispatch progress-tracker with ACTION=read.
3. No progress found, so dispatch preflight-checker with PHASES=1-7.
4. Read ./references/phases-1-4.md and enter Phase 1.
5. Invoke downstream skill fetching-github-issue.
6. Dispatch artifact-validator for Phase 1 postcondition.
7. Dispatch progress-tracker with ACTION=update, PHASE=1, STATUS=complete.
8. Tell the user: Issue fetched. Moving to task planning.

The orchestrator keeps only that summary, the issue slug, and the next phase. </example>
