GitHub Release Analyzer

Use this skill as a fixed pipeline:

prepare -> summarize -> render -> deliver -> commit

Only summarize is free-form. prepare, render, and commit are deterministic script steps.

Inputs

• Repo input: https://github.com/<owner>/<repo> or <owner>/<repo>
• Default stateKey: {owner}__{repo}
• Default template: default
• Default behavior:

- manual: latest formal release only, no state read/write - cron: formal releases only, first run selects latest only, later runs select unprocessed only

Workflow

1. Read references/execution-modes.md and choose manual or cron.
2. Run:

python3 skills/github-release-analyzer/scripts/run.py prepare --repo <repo> --mode <manual|cron>

Useful flags:

• --state-key <key>
• --limit <n>
• --include-prerelease
• --output-template default
• --initial-cron-behavior latest-only

1. If status=has_updates, read references/summary-contract.md and produce one summary string per selected release.

Keep the summary language aligned with the primary language of the invocation instruction.

1. Render the final message:

python3 skills/github-release-analyzer/scripts/run.py render --repo <repo> --mode <manual|cron> < payload.json

When building the render payload, preserve the release fields required by render, especially tag_name, published_at, and html_url.

1. In cron mode, after successful delivery, commit state:

python3 skills/github-release-analyzer/scripts/run.py commit \
  --repo <repo> \
  --mode cron \
  --processed-tags <comma-separated-tags> \
  --latest-release-id <id> \
  --latest-published-at <iso8601>

Rules

• Treat prepare output as the source of truth for selection, ordering, first-run behavior, repo normalization, and state path.
• The output language must follow the primary language of the invocation instruction.
• The final outgoing message must come from render.
• In cron mode:

- if status=no_update or status=no_release, reply with NO_REPLY - if status=has_updates, emit only the final rendered message

• Update processed state only after successful delivery.

Hard prohibitions

• Do not skip prepare.
• Do not bypass render.
• Do not reorder or silently drop releases selected by prepare.
• Do not call commit in manual mode.
• Do not call commit before delivery succeeds in cron mode.
• Do not replace the summary contract with ad hoc prose outside the required summaries[] string-array shape.
• In cron mode, when status=no_update or status=no_release, reply exactly NO_REPLY.
• In cron mode, do not emit progress chatter, intermediate JSON, step labels, or workflow narration.
