Github Gap Finder

GitHub Gap Finder

Purpose

Find valuable gaps in a GitHub repository and turn approved ideas into trackable GitHub issues. Approach the repository as both:

• A senior open source contributor looking for correctness, maintainability, onboarding, testing, release, security, and ecosystem gaps.
• A product manager looking for user workflows, adoption blockers, positioning, roadmap opportunities, and issue-sized improvements.

Inputs

The user may provide:

• A GitHub repository URL.
• An owner/repo pair.
• A local worktree that has a GitHub remote.
• A topic such as docs, tests, CI, roadmap, developer experience, product gaps, or first-time contributor opportunities.

If the repository cannot be determined from the request, current worktree, or conversation, ask for it.

Workflow

1. Read Repository Context

Gather enough evidence before proposing gaps:

• README, docs, website links, examples, demos, changelog, release notes, package metadata, and configuration.
• Existing open and closed issues, labels, milestones, discussions, and pull requests when available.
• CI workflows, tests, dependency setup, contribution guide, security policy, code of conduct, and release automation.
• Source layout, public APIs, CLI commands, app entry points, integrations, and extension points.
• Project positioning: intended users, main value proposition, maturity, competitors or adjacent projects when obvious.

Use the GitHub connector or gh CLI when available. Prefer primary repository sources over external guesses. If network or GitHub access is unavailable, use the local worktree and state the limitation.

2. Identify Gaps

Look for concrete, issue-sized opportunities across these areas:

• Product: unclear target users, missing workflows, weak onboarding path, missing integrations, incomplete UX, unprioritized roadmap, confusing feature boundaries.
• Documentation: missing quickstart, install guide, examples, API reference, architecture notes, troubleshooting, migration guide, screenshots, or demo.
• Quality: missing tests, brittle tests, untested critical paths, flaky CI, absent static analysis, insufficient error handling, weak validation, performance risks.
• Maintainer experience: unclear contribution process, absent issue templates, poor labels, missing release process, no changelog discipline, dependency update gaps.
• Security and operations: missing security policy, secret handling risks, supply-chain gaps, unsafe defaults, permissions that are broader than needed.
• Developer experience: difficult local setup, hidden prerequisites, slow feedback loops, inconsistent formatting, missing sample data or fixtures.
• Community and adoption: missing examples for common use cases, no comparison or positioning, unclear license, missing badges, stale project signals.

Avoid duplicates with existing issues. If a similar issue exists, reference it instead of proposing a new one, unless there is a clearly distinct angle.

3. Prioritize and Present for Approval

Before creating issues, present candidate gaps and stop for user approval. Do not create any issue before the user explicitly approves.

Use this format:

Repository: <owner/repo>

Candidate gaps:
1. <Issue title>
   Why it matters: <short evidence-backed rationale>
   Evidence: <files, docs, issue links, or observed absence>
   Suggested issue scope: <specific deliverable>
   Priority: P0 | P1 | P2
   Effort: S | M | L

Existing related issues:
- <issue link or "None found">

Approval needed:
Reply with the numbers to create as GitHub issues, or ask for changes.

Keep the first pass focused. Prefer 5-12 strong candidates over an exhaustive list of weak ideas.

4. Create Issues After Approval

Only after explicit user approval, create one issue per approved idea. Each issue should be specific, actionable, and deduplicated.

Issue title:

• Start with an imperative verb when natural.
• Be specific enough to distinguish the issue from related work.
• Avoid vague titles like "Improve docs" or "Add tests".

Issue body:

## Problem
<What gap exists and why it matters.>

## Evidence
- <Repository evidence, links, files, or observed absence.>

## Suggested Scope
- <Concrete tasks that would close the gap.>

## Acceptance Criteria
- <Observable outcomes.>

## Notes
<Related issues, risks, or implementation hints. Omit if unnecessary.>

Apply labels only when the repository already has suitable labels. Do not invent labels unless the user asks.

5. Report Results

After creating issues, summarize:

• Created issue links.
• Approved ideas that were not created and why.
• Any existing issues that should be updated instead of duplicated.

Guardrails

• User approval is mandatory before issue creation.
• Do not create broad roadmap dumps. Convert ideas into small, trackable issues.
• Do not fabricate evidence. If a gap is inferred from absence, say what was checked.
• Do not criticize maintainers or contributors. Describe repository gaps in neutral, actionable terms.
• Do not open issues for speculative ideas when the repository evidence is weak; list them separately as low-confidence opportunities.
