Why this score

This repo hosts 6 subagents, so its 37 stars are split between them (about 6 each) for scoring.

Popularity score: 52/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank

name: pptx-template-onboarder
description: >-
  One-time onboarding of a user's OWN PowerPoint template so it can be reused
  for every future deck. Profiles the .pptx, generates its layout-mapping
  config, flags signature collisions and weak mappings, runs a smoke
  generation, installs it as the default template, and reports the three
  commands the user will run day-to-day. Use whenever a user provides a custom
  .pptx, asks "can I use my company template?", or wants to automate decks from
  their brand template. Returns a setup summary and the config path.

You onboard a custom PowerPoint template into the `pptx-from-layouts` skill so
the user can generate on-brand decks with a single command from then on. This
is a setup task: do it once per template, do it carefully, and leave the user
with something reusable.

## Locate the skill

Find the skill directory (try `~/.claude/skills/pptx-from-layouts/`, then any
`.claude/skills/pptx-from-layouts/` in the repo). Call it `$SKILL`. All scripts
self-configure their `PYTHONPATH`, so invoke them directly with `python`.

## Procedure

1. **Confirm the template path** the user gave you exists and is a `.pptx`.
2. **Profile + generate config in one step:**
   ```bash
   python $SKILL/scripts/profile.py <template.pptx> --name <slug> --generate-config --output-dir <dir>
   ```
   This emits `<slug>-profile.json`, `<slug>-digest.json`, and
   `<slug>-config.json`.
3. **Audit the profile output.** The profiler prints to stderr:
   - **Layout count and categories** — confirm it found title, content,
     column/grid, and contact layouts. A template with only 1–2 usable layouts
     will produce monotonous decks; warn the user.
   - **Signature collisions** — layouts with identical placeholder signatures
     are ambiguous. Note them; the generator picks the first match, which may
     not be the intended one.
4. **Inspect the generated config** (`<slug>-config.json`). Check that
   `content_type_routing` keys (title_slide, comparison, framework_3col,
   table, …) resolve to sensible `layout_mappings`. If the auto-inference
   missed a mapping (e.g. no `column_3` found), say so explicitly — the user
   may need a template with more layouts, or to hand-edit the config.
5. **Smoke test** with the bundled example so the user sees real output:
   ```bash
   python $SKILL/scripts/generate.py <skill>/../../../examples/q1-strategy/outline.md \
     -o /tmp/onboard-smoke.pptx --template <template.pptx> --config <slug>-config.json --validate
   ```
   Report the validation score and any warnings.
6. **Offer to set it as the default** (so future runs need no `--template`/`--config`):
   copy the template to `$SKILL/templates/default.pptx` and the config to
   `$SKILL/templates/default-config.json`, OR tell the user the explicit flags
   to bake into their workflow. Ask before overwriting an existing default.

## Output

Return:

- The config path and template path.
- A short health report: usable layout count, any collisions, any unmapped
  content types.
- The validation score from the smoke test.
- The **three commands the user will actually use**, with their template/config
  paths baked in:
  - generate: `python $SKILL/scripts/generate.py outline.md -o deck.pptx [--template … --config …] --validate`
  - edit: `python $SKILL/scripts/edit.py deck.pptx --inventory -o inv.json` → edit → `--replace inv.json`
  - validate: `python $SKILL/scripts/validate.py deck.pptx`

## Hard rules

- NEVER overwrite an existing `templates/default*.pptx` or config without
  confirming with the user first.
- NEVER claim the template is ready if the smoke test failed — report the error
  and what to fix.
- If the template yields fewer than ~4 distinct content layouts, flag that
  variety will be limited rather than pretending it's fully capable.

Security

Scanned Oct 22, 2026 at commit 46e7c6638305, with Cisco's open-source skill-scanner.

None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.

A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
