name	lisa-github-to-tracker
description	Break down a GitHub Issue PRD into Epics, Stories, and Sub-tasks in the configured destination tracker (JIRA via lisa-tracker-write → lisa-jira-write-ticket, or GitHub Issues itself via lisa-tracker-write → lisa-github-write-issue). Use this skill whenever the user shares a GitHub issue URL and wants it converted into tickets, or asks to "break down this GitHub PRD", "create tickets from a GitHub issue", or similar. This skill mirrors lisa-notion-to-tracker / lisa-confluence-to-tracker / lisa-linear-to-tracker for projects whose PRDs live in GitHub Issues — the workflow, gates, dry-run mode, and validation rules are identical; only the source-of-truth tool surface differs (the `gh` CLI instead of Notion / Confluence / Linear MCP).

GitHub PRD to Tracker Breakdown

Convert a GitHub Issue PRD into a structured ticket hierarchy in the configured destination tracker: Epics > Stories > Sub-tasks. Each Sub-task is scoped to exactly one repo and includes an empirical verification plan.

This skill is the GitHub counterpart of lisa-notion-to-tracker / lisa-confluence-to-tracker / lisa-linear-to-tracker. The four skills share the same phases, gates, dry-run contract, and per-ticket validation logic. Only the PRD-side fetch tools differ. When changing workflow logic, change ALL FOUR skills together so the PRD vendors stay behaviorally identical.

What "PRD" means in GitHub Issues

GitHub Issues has no native "PRD" entity. This skill treats a single GitHub Issue (carrying the configured ready PRD label — github.labels.prd.ready, default prd-ready) as the PRD container:

• Issue body (markdown) is the PRD body — equivalent to a Notion page body, a Confluence page body, or a Linear project description.
• Sub-issues (native GitHub sub-issues, traversable via gh api graphql) act as the candidate set for Epics or User Stories — the same role child Epic pages play in a Notion/Confluence PRD.
• Issue comments capture decisions, engineering notes, product clarifications.
• Linked PRs (parsed from Resolves #<n> lines and from native cross-references) provide implementation context.

A multi-Epic PRD is encoded as a parent Issue with several child sub-issues. A simple PRD is a single Issue with body content only.

Modes

This skill supports two modes, controlled by a dry_run flag in $ARGUMENTS:

• dry_run: false (default — full mode): run all phases, write tickets via lisa-tracker-write, run the preservation gate, report.
• dry_run: true (planning + validation only — no writes): run Phases 1, 1.5, 1.6, 2, 3, 4 to plan the hierarchy and draft each ticket spec, then call lisa-tracker-validate (with --spec-only) on every drafted ticket. Aggregate the per-ticket validator reports into a single dry-run report. Skip Phase 5 (sub-task creation), Phase 5.5 (preservation gate), and Phase 6 (results report) — none of those make sense without writes. Return the dry-run report so the caller (e.g. lisa-github-prd-intake) can decide whether to proceed.

Dry-run output format is identical to lisa-notion-to-tracker / lisa-confluence-to-tracker / lisa-linear-to-tracker. Reuse the same fields, including prd_anchor and prd_section. For GitHub, prd_anchor is a section heading from the PRD body when the failure traces to a specific section; otherwise null (the caller posts unanchored failures as a rollup comment on the PRD issue).

## github-to-tracker dry-run: <PRD title>

### Planned hierarchy
- Epic: <summary>
  prd_section: "<heading text from the PRD body or sub-issue title that produced this epic>"
  prd_anchor: "<heading text or sub-issue ref or null>"
  - Story 1.1: <summary>
    prd_section: "<heading or user-story line>"
    prd_anchor: "<heading or sub-issue ref or null>"
    - Sub-task [<repo>]: <summary>
      prd_section: "<heading or AC bullet>"
      prd_anchor: "<heading or sub-issue ref or null>"
    - ...
  - Story 1.2: ...

### Per-ticket validation
- <ticket-ref>: PASS | FAIL — <count> failures
  prd_section: "<heading text>"
  prd_anchor: "<heading or sub-issue ref or null>"
  failures:
    - gate: <gate-id>
      category: <category from validator>
      product_relevant: <true|false>
      what: <plain-language description from validator>
      recommendation: <1–3 candidate resolutions from validator>

### Verdict: PASS | FAIL
### Total failures: <n>

The dry-run mode never writes to the destination tracker. It also never modifies the source PRD issue, never adds/removes labels, never edits sub-issues, and never posts comments — that is the orchestrating skill's responsibility (lisa-github-prd-intake).

Hard Rule: All Writes Go Through lisa-tracker-write

Every ticket created by this skill — every Epic, Story, and Sub-task — MUST be created by invoking the lisa-tracker-write shim. Never call lisa-jira-write-ticket, lisa-github-write-issue, mcp__atlassian__createJiraIssue, or gh issue create directly from this skill or from any sub-agent it spawns.

lisa-tracker-write enforces:

• Vendor-agnostic dispatch (so a project's destination is one config edit away).
• The vendor writer's pre-write gate (lisa-tracker-validate Phase 5.5).
• Post-write verify (lisa-tracker-verify).
• 3-audience description, Gherkin acceptance criteria, parent / Epic validation, link discovery, single-repo scope, sign-in / target environment fields, source-artifact preservation.

Bypassing the shim layer produces tickets that the rest of the lifecycle (triage, verify, journey, evidence) treats as broken.

The gh reads in this skill are limited to reading the source PRD issue, its sub-issues, and its comments. They never write.

Input

A GitHub issue ref. The PRD is expected to have:

• An issue body containing context, problems, and (optionally) a list of user stories.
• One or more sub-issues that act as candidate Epics or user stories (optional — single-issue PRDs are valid).
• Issue comments capturing engineering notes and product decisions.
• The configured ready PRD label (github.labels.prd.ready, default prd-ready — if invoked from lisa-github-prd-intake; for ad-hoc / direct invocation the label is informational, not gating).

URL parsing — accept either:

• org/repo#<number>
• https://github.com/<org>/<repo>/issues/<number>

Resolve <org>/<repo> from .lisa.config.json if $ARGUMENTS is just #<n> or a bare number.

Configuration

This skill reads project configuration from .lisa.config.json (with .lisa.config.local.json overriding per key) and operational E2E test config from environment variables. See the config-resolution rule for the full schema.

From .lisa.config.json

This skill is a PRD source (GitHub Issues). Destination tracker resolution is handled by lisa-tracker-write / lisa-tracker-validate internally; this skill reads only the source-side config.

Field	Purpose	Required when
github.org	GitHub org hosting the PRD repo	always (source repo); also when tracker = "github" (destination repo, can be the same in self-host case)
github.repo	GitHub repo hosting the PRD	same

From environment variables (E2E test config — operational, not tracker)

Variable	Purpose	Example
E2E_TEST_PHONE	Test user phone for verification plans	0000000099
E2E_TEST_OTP	Test user OTP code	555555
E2E_TEST_ORG	Test organization name	Arsenal
E2E_BASE_URL	Frontend base URL for Playwright tests	https://dev.example.io/
E2E_GRAPHQL_URL	GraphQL API URL for curl verification	https://gql.dev.example.io/graphql

If env vars are not available, ask the user to provide them explicitly before proceeding. Do not retrieve credentials from repository files or local agent settings.

Workflow

Phase 1: Fetch & Analyze the PRD

1. Confirm gh auth status succeeds.
2. Fetch the PRD issue via gh issue view <num> --repo <org>/<repo> --json number,title,body,labels,milestone,assignees,author,createdAt,comments,url. Capture title, body, labels, author, assignees, dates, comments.
3. Fetch native sub-issues via the GraphQL subIssues traversal (see lisa-github-read-issue Phase 3). Each sub-issue's {number, title, body, labels, state, url} becomes a candidate epic / story node.
4. Recursively fetch grandchild sub-issues (one more level — typical PRD depth is 2: PRD → Epic candidate → maybe a Story candidate). Stop after depth 3 unless the user explicitly requested deeper.
5. Fetch full comments per sub-issue via gh issue view <num> --repo <org>/<repo> --json comments for every sub-issue surfaced in step 3. Capture body, author, timestamp.
6. Synthesize decisions and blockers from the PRD body + every sub-issue body + every comment thread:
   • Decisions already confirmed by the team (look for agreement in comments).
   • Open questions that need product/engineering input.
   • Engineering comments (prefixed with "Engineering:" or 🔧) that identify technical constraints.
   • Cross-PRD dependencies (references to other GitHub issues, Notion / Confluence / Linear PRDs, shared infrastructure).

Phase 1.5: Extract Source Artifacts

PRDs typically reference external design, UX, and data artifacts (Figma files, Lovable prototypes, Loom walkthroughs, screenshots, example payloads, peer Notion / Confluence / Linear pages). These MUST be preserved onto the resulting tickets — otherwise developers picking up a ticket lose the source of truth. This is the failure mode this step exists to prevent.

1. Scan the PRD body, every sub-issue body, and every comment for:

   • URLs to design/prototype tools (Figma, FigJam, Figma Make, Lovable, Framer, Penpot)
   • URLs to recording/walkthrough tools (Loom, YouTube, Vimeo, Descript)
   • URLs to collaborative docs (Google Docs/Slides/Sheets, peer Confluence pages, Notion peer pages, peer Linear documents)
   • URLs to code sandboxes (CodeSandbox, StackBlitz, Replit, GitHub permalinks/gists)
   • URLs to diagramming tools (Miro, Mural, Excalidraw, Mermaid Live, draw.io, Lucid)
   • URLs to data/observability tools (Grafana, Datadog, Sentry, Metabase, Looker)
   • Embedded images and file attachments referenced in the body
   • Fenced code blocks with example data (JSON, SQL, GraphQL, cURL request/response)

2. Classify each artifact and apply taxonomy rules by invoking the lisa-tracker-source-artifacts skill. That skill is the single source of truth for: domains (ui-design / ux-flow / data / ops / reference), per-tool classification rules, and coverage smells.

3. Build an artifacts map keyed by domain. Each entry: { url, title, domain, source_page, source_page_url, classification_reason }. source_page lets you trace each reference back to where it appeared (PRD body vs a specific sub-issue vs a specific comment).

4. Surface coverage smells as defined in lisa-tracker-source-artifacts §5. Record on the Epic.

Phase 1.6: Source Precedence & Conflict Resolution

Source precedence rules and cross-axis conflict handling are defined in lisa-tracker-source-artifacts §3 and §4. Apply them during ticket synthesis: every conflict between artifacts must be recorded under ## Open Questions on the affected ticket, never silently reconciled.

The existing-component reuse expectation is defined in lisa-tracker-source-artifacts §7. Encode it on every UI-touching story.

Phase 2: Codebase + Live Product Research

Identical to lisa-notion-to-tracker Phase 2 / lisa-confluence-to-tracker / lisa-linear-to-tracker. Two complementary inputs ground PRD analysis: the code and the live product.

2a. Codebase research. If the session doesn't already have codebase context, explore the repos. Use Explore agents for repos not yet examined.

2b. Live product walkthrough. If the PRD touches existing user-facing surfaces, invoke lisa-product-walkthrough against E2E_BASE_URL using the test user from config.

Skip 2b only when the work is purely backend with no user-visible surface, or affects a screen that does not yet exist.

Walkthrough findings are surfaced back to product via the orchestrating intake skill (lisa-github-prd-intake), which posts them as a comment on the PRD issue. This skill itself does NOT post to GitHub — it only reads. The walkthrough section is also inherited onto the resulting Epic / Stories under a ## Current Product subsection.

Phase 3: Create Epics

Mode guard: In dry_run: true mode, do not invoke lisa-tracker-write in this phase. Instead, draft the epic spec (summary, body, artifacts) and validate it with lisa-tracker-validate --spec-only. Record the drafted spec (with a placeholder ref like DRY-RUN-EPIC-1) for Phase 4 to use as parent references. In dry_run: false mode, proceed as described below.

For each epic identified in Phase 1, invoke the lisa-tracker-write shim (do not call lisa-jira-write-ticket or lisa-github-write-issue directly). Pass it everything it needs to enforce its quality gates:

• issue_type: Epic
• summary: epic title from the PRD
• body: a draft of the multi-section description containing:
  • Context / Business Value: epic summary from the PRD, originating GitHub PRD URL, business outcome
  • Technical Approach: cross-cutting integration points and constraints surfaced in Phase 2 codebase research
  • List of user stories the epic contains
  • Key decisions from comments (with attribution)
  • Blockers and open questions
  • Dependencies on other epics or PRDs
  • A Source Artifacts section listing every artifact extracted in Phase 1.5 (grouped by domain)
• artifacts: the full Phase 1.5 artifact list — every artifact, regardless of domain. The Epic is the canonical hub.
• priority, labels, components, fix_version: as appropriate

The source GitHub PRD may span multiple repositories, and the Epics created from it may stay cross-repo when they are coordination containers rather than buildable leaf work.

Leaf-only build-ready (leaf-only-lifecycle): an Epic is a container, not a leaf work unit. Do NOT mark it build-ready — lisa-tracker-write must not be passed status:ready for an Epic, and the Epic's lifecycle state rolls up from its children. Epics may span repositories; only the leaf work created later must collapse to one repo each. The build-ready label is applied only in Phase 5.

Capture the returned epic ref — Phase 4 needs it as the parent for Stories.

Phase 4: Create Stories

Mode guard: In dry_run: true mode, do not invoke lisa-tracker-write. Draft each story spec and validate it with lisa-tracker-validate --spec-only. Use placeholder refs (e.g. DRY-RUN-STORY-1.1).

For each Epic, plan two kinds of Stories:

• One "X.0 Setup" story for data model and infrastructure prerequisites
• One story per user story from the PRD (numbered to match the PRD's structure or the source sub-issues)

Story naming convention: Prefix the summary with a short code derived from the PRD title (e.g., [CU-1.1] for "Contract Upload").

For each Story, invoke lisa-tracker-write with:

• issue_type: Story
• parent_ref / epic_parent: the Epic ref captured in Phase 3 (mandatory)
• summary: prefixed per the naming convention above
• body: multi-section description as in lisa-notion-to-tracker Phase 4
• artifacts: the Phase 1.5 artifacts filtered by domain per the inheritance table:

Story type	Inherits domains
Frontend / UI	ui-design, ux-flow, reference
Backend / API / data model	data, reference
Infrastructure	ops, reference
Mixed / setup ("X.0")	All domains

Leaf-only build-ready (leaf-only-lifecycle): a Story is a container (it has child Sub-tasks), not a leaf work unit. Do NOT mark it build-ready — never pass status:ready to lisa-tracker-write for a Story. Its lifecycle state rolls up from its Sub-tasks. Stories may span repositories when they coordinate work across repos; the build-ready label is applied only in Phase 5 to the per-repo leaves.

Capture each returned story ref — Phase 5 needs it.

Phase 5: Create Sub-tasks

Auto-split cross-repo work before delegation. For each candidate sub-task, apply lisa-task-decomposition step 1.5: if the work touches more than one repo, split it into one sub-task per repo under the same parent Story (e.g., [backend-api] Add field + [mobile-app] Display field), and encode the producer-before-consumer ordering via dependencies. The source GitHub PRD and its coordination containers (Epic, Story, Spike) may remain cross-repo. Build-ready work units may not: every Bug, Task, Sub-task, or Improvement written from this phase must resolve to exactly one repository. Splitting is this skill's responsibility — the validator's S10 gate is product_relevant: false because cross-repo failures are decomposition errors caught here, not product questions sent back to the PRD.

S10 hard gate repair loop. Dry-run validation is not advisory. Before any Phase 5 write, every planned leaf spec MUST pass lisa-tracker-validate --spec-only for S10 Single-repo scope. If any Bug / Task / Sub-task / Improvement fails S10 (missing Repository, more than one repo, or cross-repo AC), stop the write path, auto-split or restamp the spec using lisa-task-decomposition step 1.5, add the repo bracket and ## Repository / h2. Repository section, then re-run lisa-tracker-validate --spec-only. If S10 still fails after repair, abort the ticket write and record an internal Error in the dry-run report; do not create the ticket, do not bypass with direct vendor writes, and do not surface the product_relevant: false failure as a product clarification.

Delegate sub-task creation to parallel agents (one per epic or batch of stories) for efficiency. Every spawned agent must invoke lisa-tracker-write for each sub-task — no agent may call lisa-jira-write-ticket / lisa-github-write-issue / gh issue create directly.

Each sub-task MUST:

1. Be scoped to exactly ONE repo — indicated in brackets in the summary: [repo-name] and in the body/description's ## Repository / h2. Repository section.
2. Include an Empirical Verification Plan — real user-like verification, NOT unit tests, linting, or typechecking.

Leaf-only build-ready (leaf-only-lifecycle): Sub-tasks are the leaf work units of the decomposition — they are the ONLY items in the hierarchy that receive the build-ready label. lisa-tracker-write applies status:ready here so downstream build intake (lisa-github-build-intake) claims the leaves and never the Epic or Stories. Apply status:ready to each Sub-task; never to its parent Story or Epic (Phases 3–4). lisa-github-write-issue enforces the same invariant on the write side, so a Sub-task split into per-repo children (the cross-repo case above) carries build-ready on the children, not on any intermediate parent that gains child work.

Sub-tasks inherit their parent Story's artifacts by reference (the parent link). Do not pass the same artifact list to every sub-task.

Phase 5.5: Artifact Preservation Gate (mandatory)

Run the preservation gate defined in lisa-tracker-source-artifacts §8 against the artifacts extracted in Phase 1.5 and the tickets just created. Do NOT restate or modify the gate logic here — invoke the rules from lisa-tracker-source-artifacts.

To run the gate, this skill must:

1. Pull the remote links / ## Source Artifacts section / ## Links section of every Epic and Story created in this run via lisa-tracker-read.
2. Apply the §8 preservation matrix and verdict rules.
3. If the gate fails: list each dropped/misrouted artifact and either re-attach via lisa-tracker-write (UPDATE mode) or stop and ask the human.
4. If the gate passes: print the matrix compactly and proceed to Phase 6.

This gate is not optional.

Phase 6: Report Results

After all tickets are created, present a summary table to the user:

• All Epics with refs and URLs
• All Stories grouped by Epic
• All Sub-tasks grouped by Story with repo tags
• Repo distribution
• Artifact Preservation Matrix
• Blockers list with recommendations and alternatives
• Cross-PRD dependencies

Phase 7: PRD Back-link

Mode guard: In dry_run: true mode, skip this phase entirely — no tickets exist to link.

After Phase 6, invoke the lisa-prd-backlink skill to write a ## Tickets section back into the source GitHub Issue PRD body. The section becomes the canonical anchor for the Debrief flow once the initiative ships.

Invoke lisa-prd-backlink with:

• source_type: "github"
• source_ref: the original GitHub Issue URL or <org>/<repo>#<n> token
• tickets: the full list created in Phases 3–5, each entry as { key, title, type, url, parent_key }

If lisa-prd-backlink fails (permission denied, GitHub unreachable, issue locked), surface the error in the Phase 6 report rather than aborting — the tickets are already created. Recommend the user re-run lisa-prd-backlink standalone once the source is reachable.

Handling Ambiguities and Blockers

When you encounter something the PRD + comments + codebase can't resolve:

1. Don't guess — mark the ticket with a BLOCKER section.
2. Include your recommendation with rationale.
3. List 2-3 alternatives so the user/product can choose.
4. State what's needed to unblock.

Agent Prompt Template for Sub-task Creation

When delegating to agents, provide this context. The "MUST invoke tracker-write" instruction is load-bearing — do not edit it out when adapting this template.

Create Sub-tasks via the configured destination tracker.

CRITICAL: For each sub-task, invoke the `lisa-tracker-write` skill via the Skill tool.
Do NOT call `lisa-jira-write-ticket`, `lisa-github-write-issue`, or `gh issue create` directly.
The `lisa-tracker-write` shim dispatches to the configured destination AND enforces required
quality gates (Gherkin acceptance criteria, multi-section description, single-repo scope,
sign-in/environment fields, post-create verification). Bypassing it produces broken tickets
that downstream skills (triage, journey, evidence) cannot use.

For each sub-task, invoke `lisa-tracker-write` with:
- issue_type: "Sub-task"
- parent_ref: the parent story ref
- summary: prefixed with the repo in brackets, e.g. "[backend-api] Add audit log table"
- body: a multi-section draft (Context / Technical Approach / Acceptance Criteria / etc.) plus `## Repository` / `h2. Repository` naming exactly one repo
- gherkin_acceptance_criteria: derived from the story's functional requirements
- sign_in_account: [test user credentials from config]
- target_environment: "dev"
- empirical_verification_plan: real user-like verification (curl + auth token, Playwright
  browser flow, CLI check after deploy) using the test credentials. NOT unit tests.

Each sub-task must:
1. Be scoped to ONE repo only — repo named in brackets in the summary and in `## Repository` / `h2. Repository`.
2. Include the Empirical Verification Plan in the body.
3. Be created via `lisa-tracker-write`, not via direct calls.

If `lisa-tracker-write` rejects a sub-task, fix the input and re-invoke. Do NOT fall back
to a direct vendor-write call to bypass the gate.

Test user info: [credentials from config]

[Then list all sub-tasks grouped by parent story with details]

Cross-PRD Shared Infrastructure

Track tickets that are shared across PRDs to avoid duplication. When a sub-task overlaps with an existing ticket, reference it instead of creating a duplicate. Use lisa-tracker-read to search the destination for existing tickets in the same area before creating new ones for shared infrastructure.

GitHub-specific notes

• Body format: GitHub Issues bodies are markdown. Treat headings (#, ##, ###) as section markers for prd_section.
• Native sub-issues: GitHub native sub-issues (the addSubIssue GraphQL mutation) are how Epic→Story→Sub-task is encoded when the destination is also GitHub Issues. The PRD-side reads them via the subIssues GraphQL field.
• Comment threading: GitHub Issues comments are flat — there's no parentId (unlike Linear). Decision context is captured by chronological position; quote the comment author + timestamp when surfacing it.
• Anchoring on PRD comments: GitHub Issues do not have a Confluence-style selection-anchored inline-comment primitive. The orchestrating skill (lisa-github-prd-intake) approximates by quoting the relevant body excerpt at the top of each comment. The dry-run report's prd_anchor is the section heading the failure traces to (or null for body-wide failures).
• Self-host edge case: when tracker = "github" AND the source PRD repo is the same as the destination repo, both reads and writes hit one place. The PRD carries prd-* labels; built tickets carry type:* + status:* labels. The two namespaces never overlap. lisa-prd-ticket-coverage filters out the source PRD itself when listing destination tickets.
