GitHub Validation Journey

Parse a GitHub Issue's Validation Journey, execute the verification steps using the appropriate tools for the change type, capture evidence at each [EVIDENCE: <name>] marker, and post to the issue + GitHub PR.

Arguments

$ARGUMENTS: <ISSUE_REF> [PR_NUMBER]

• ISSUE_REF (required): GitHub issue ref — org/repo#<number> or full GitHub issue URL.
• PR_NUMBER (optional): GitHub PR number for the implementation PR. If omitted, the skill auto-detects the PR from lisa-github-read-issue's linked-PR list (preferring the most recent open PR).

Prerequisites

• gh CLI authenticated.
• Appropriate services running for the verification type (dev server, database, etc.).

Workflow

Step 1: Parse the Validation Journey

gh issue view <number> --repo <org>/<repo> --json body --jq '.body'

Extract the ## Validation Journey section (plus its ### Prerequisites, ### Steps, and ### Assertions sub-sections). Parse each step into a structured form: { index, text, evidence_marker (or null) }.

If the issue has no Validation Journey, stop and instruct the caller to run /github-add-journey <issue-ref> first.

Step 2: Satisfy Prerequisites

Before starting the journey, verify each prerequisite:

1. Check if required services are running (curl localhost:<port>/health, pg_isready, etc.).
2. Verify database connectivity if the journey touches data.
3. Ensure environment variables are set.
4. Run any setup commands mentioned in ### Prerequisites.

Step 3: Execute Steps and Capture Evidence

Execute each step sequentially. Determine the verification approach based on the step text and the issue's change type (inferred from type: label, component: labels, and the body):

• API endpoints → Run curl commands, capture HTTP response to evidence/NN-name.txt (or .json).
• Database changes → Run psql/migration commands, capture schema output.
• Background jobs → Trigger the job, check queue/state, capture logs.
• Library/utility changes → Run tests, capture output.
• Security fixes → Reproduce exploit attempt, verify fix, capture output.

At each [EVIDENCE: name] marker, capture stdout/stderr to a numbered file:

Evidence Naming Convention

{NN}-{evidence-name}.txt (or .json for structured data):

• NN: zero-padded sequential number (01, 02, 03...).
• evidence-name: the value from [EVIDENCE: <name>] (kebab-case).

Example:

evidence/
  01-health-check.json
  02-schema-after-migration.txt
  03-rate-limit-response.txt
  comment.md

Step 4: Generate Evidence Templates

Compose evidence/comment.md with:

• The issue ref + title.
• The PR ref.
• Each evidence marker rendered as a GitHub markdown section with a fenced code block of the captured file.
• An "Assertions verified" subsection mapping each ### Assertions line to "PASS / FAIL".

This template generator is shared with lisa-jira-journey (the JIRA path renders the same content as wiki markup). When the markdown comment is the canonical artifact, both vendors stay aligned.

Step 5: Post Evidence

Use lisa-github-evidence to post everything:

# Equivalent of: bash scripts/post-evidence.sh — but invoked via the Skill tool

Invoke the skill with <ISSUE_REF> ./evidence <PR_NUMBER>. It uploads the files to the pr-assets release, edits the PR's ## Evidence section, and posts a comment on the issue. The build-intake owner performs the direct claimed → done lifecycle transition after success.

Step 6: Verify

Confirm:

• Evidence files exist as release assets named pr-<PR>-NN-name.{txt,json}.
• The PR description contains the ## Evidence section with code-block embeds.
• The issue has a new comment whose body matches comment.md.
• The issue has the evidence comment, and the build-intake owner can transition it from status:in-progress directly to the configured done label.

Verification Patterns Reference

Change Type	Verification Method	Evidence Format
API endpoint	curl -s localhost:PORT/endpoint	JSON response
Database migration	psql -c "\d table" or migration output	Schema text
Background job	Trigger + check state	Log output
Library/utility	bun run test -- path/to/test	Test output
Security fix	Reproduce + verify fix	Request/response
Auth/authz	Multi-role verification	Status codes per role

Troubleshooting

Evidence file is empty

Ensure the command succeeded and produced output. Use 2>&1 to capture both stdout and stderr.

Parser returns no steps

The issue may not have a Validation Journey section — run /github-add-journey <ISSUE_REF> first.
