* Add arch plugin (architecture + modernization skills)

Add the `arch` plugin with two skills:
- `arch:document` — produce a single, cited architecture document for a
  locally-cloned repo, reading files on disk only.
- `arch:modernize` — generate a phased modernization plan, auto-running the
  document workflow first when no architecture doc exists.

Skill sources live in top-level skills/ and are referenced declaratively
from plugins/arch/.github/plugin/plugin.json, per the repo's plugin model.
Regenerated docs/README.plugins.md, docs/README.skills.md and marketplace.json.

* Merge arch skills into single doc-and-modernize skill

Collapse the document and modernize skills into one standalone skill
(doc-and-modernize) with Documentation and Modernization modes, keeping
the plugin named arch. Modernization mode now runs the Documentation
workflow inline instead of invoking a separate arch:document skill,
fixing standalone-install cross-skill references. Reframe Documentation
mode as local-first (remote/API lookups are a flagged last resort)
rather than local-only. Regenerate docs and marketplace.

* Address PR review: list skill by bare ID in arch README

Use 'doc-and-modernize' (repo convention) instead of the namespaced
'arch:doc-and-modernize', noting it surfaces as arch:doc-and-modernize
when installed via the plugin.

* Address PR review: use non-HTML placeholder in instructions template

Change plain-text <PROJECT NAME> to [PROJECT NAME] in the header and
first paragraph so Markdown renderers don't parse it as an HTML tag and
drop it. The code-span `<N>` on the phase line is unaffected.

* Address PR review + fix codespell CI failure

- Fix codespell: pre-empts -> preempts in the instructions template
- Consistent terminology: replace 'research step/workflow' with
  'Documentation mode' in SKILL.md, README, and plugin.json description
- Fix run-on: add 'that' before 'Modernization mode must surface'
- Regenerate docs/marketplace for the updated plugin description

* Address PR review feedback

- Instruct redacting credentials/tokens from git remote URLs before recording
- CI enforcement: ask user or mark [UNVERIFIED]; remote lookup is flagged last resort

Agentic Workflows

Agentic Workflows are AI-powered repository automations that run coding agents in GitHub Actions. Defined in markdown with natural language instructions, they enable event-triggered and scheduled automation with built-in guardrails and security-first design.

How to Contribute

See CONTRIBUTING.md for guidelines on how to contribute new workflows, improve existing ones, and share your use cases.

How to Use Agentic Workflows

What's Included:

  • Each workflow is a single .md file with YAML frontmatter and natural language instructions
  • Workflows are compiled to .lock.yml GitHub Actions files via gh aw compile
  • Workflows follow the GitHub Agentic Workflows specification

To Install:

  • Install the gh aw CLI extension: gh extension install github/gh-aw
  • Copy the workflow .md file to your repository's .github/workflows/ directory
  • Compile with gh aw compile to generate the .lock.yml file
  • Commit both the .md and .lock.yml files

To Activate/Use:

  • Workflows run automatically based on their configured triggers (schedules, events, slash commands)
  • Use gh aw run <workflow> to trigger a manual run
  • Monitor runs with gh aw status and gh aw logs

When to Use:

  • Automate issue triage and labeling
  • Generate daily status reports
  • Maintain documentation automatically
  • Run scheduled code quality checks
  • Respond to slash commands in issues and PRs
  • Orchestrate multi-step repository automation
