Consulting-Quality Slides with a Rulebook-First Skill

Where this fits

You've just finished your analysis and need a board-ready deck in two hours. The content is solid, but the slides look like a developer's first attempt at design—misaligned boxes, inconsistent fonts, and a story that doesn't flow. This skill solves that by putting a 80-item rulebook (slide-rules.md) at the center of the creation process. It guides an agent to read the rules first, pick a template or pipeline, adjust within constraints, and finish with a mechanical check that fails on zero violations. If you've ever wanted an agent to produce slides that survive a management review without looking template-soulless, this is the missing piece.

Why agents benefit

• Rulebook-first discipline: The agent reads slide-rules.md before every deck, so each slide inherits the accumulated wisdom from real consulting reviews—not just a generic layout library.
• Two creation lanes: Choose the freeform lane for bespoke, high-stakes decks, or the SlideSpec pipeline for rapid, editable PPTX generation from JSON specs. Both end with the same quality gate.
• Type catalog as inspiration, not constraint: The 62-type catalog is explicitly a "layout idea book," not a straitjacket. The agent is instructed to question whether a type fits the story and to discard it freely—encouraging genuine customization.
• Mechanical verification: check_deck.py runs objective checks (alignment, spacing, text overflow, etc.) and requires FAIL 0, giving you a measurable quality bar instead of subjective vibes.
• Self-improving rulebook: Feedback from adjustments is appended back to the rulebook, so the skill gets smarter with each use—a rare adaptive quality.

Practical scenarios

Board-level status deck from scratch

An agent pulls KPIs from your data source, drafts a narrative, then uses the freeform template to build each slide. It consults the rulebook for every decision—headline phrasing, chart placement, and callout boxes—and runs the checker until zero fails. You get a deck that reads like a partner made it.

Mass-producing weekly client reports

Using the SlideSpec pipeline, the agent generates a 10-slide report from a JSON spec in under a minute. It picks appropriate types from the catalog, fills in numbers, and exports an editable PPTX. You review and tweak only the exceptions, not the whole deck.

Iterating on a pitch deck with client feedback

After a client says "make this more concise," the agent re-reads the rulebook, identifies slides that violate brevity rules, and proposes alternative layouts. It can swap a dense table for a bar chart, adjust the headline, and re-run the checker—all within the rulebook's boundaries.

Add it to your agent workflow

Install the skill with:

npx skills add gozen3ji/consulting-pptx-skill --skill consulting-pptx-skill

Then trigger it with phrases like "コンサル品質のスライドを作って" or "規約に沿ったデッキで". For a quick start, point the agent at the SlideSpec pipeline with a JSON spec; for a bespoke deck, ask it to use the freeform template. The skill's README includes exact paths and examples.

Compare before adopting

• Quality signals: Does the skill enforce objective checks (FAIL 0) or just style guides? Does it have a living rulebook that updates from feedback?
• Maintenance freshness: Check the GitHub repo for recent commits and issue responses. A skill that's actively refined is more reliable.
• Alternatives: Generic PPTX generation tools (python-pptx, HTML-to-PPTX) lack the consulting-specific rules. Compare whether they offer a rulebook and a checker.
• Workflow fit: Does your agent already produce reports? This skill slots into a pipeline but also works as a standalone step. Evaluate how much you need editable PPTX vs. static images.

Why it is worth tracking

With 241 stars and a clear, opinionated design, this skill signals a shift toward rule-driven, verifiable slide generation. The rulebook's origin in real review feedback makes it more than a template collection—it's a codified practice. Watch for updates to the rulebook and the checker's coverage. If your team regularly creates client-facing decks, this is worth evaluating now. For more context, see the skill page at https://www.openagentskill.com/skills/gozen3ji-consulting-pptx-skill.
