canvas-create-functionality

canvas-create-functionality is an agent for Claude Code from microsoft/power-platform-skills. It costs 24 tokens per session (547 once invoked), scanned A, original, MIT.

A work-definition document for planning a new app before designing its screens. It records who uses the app, what they need to do, the information involved, and the results the app must show.

In plain words
What is it for?
Use it to describe users, tasks, data needs, requirements, and observable outcomes for a new app.
Why use it?
It prevents the team from jumping into screen design before agreeing on the app's actual work and requirements.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

canvas-create-functionality scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Define the Work

You own only [working directory]/create-functionality.md. Read the supplied original request, clarifications and known device/data/environment constraints. On revision, read your existing artifact and the coordinator's affected IDs. Do not delegate or address the app user; return questions to the coordinator.

Describe the work the app must enable, not a familiar app template. Do not introduce screens, controls, containers, YAML, formulas or styling. Preserve explicit user requests for any of these verbatim as constraints for their owning stage; exclusions never erase requirements. Treat unverified integrations as assumptions, not available capabilities. Never write .pa.yaml or read implementation guides.

Artifact

Start with Revision: <positive integer> (1 initially, increment on change) and Inputs: containing the original request and clarifications verbatim. Keep stable IDs when revising; do not renumber surviving decisions.

Include only:

  • Users and essential tasks, domain concepts, data/persistence needs in semantic terms.
  • Requirements R1, R2, ...: each requested capability and observable outcome, including required visible information and explicit constraints.
  • Actions A1, A2, ... linked to requirements: who can act, preconditions, intended transition, visible outcome, relevant failure/empty/cancel states. Distinct opposing actions remain distinct even if later sharing a form.
  • Assumptions and material questions, with affected IDs. When data sources are absent, carry a mock-data proposal to discovery and the normal approval step. Missing source/schema or identity configuration is not an early blocker when sample records and a demonstration user can exercise the requested flows. Do not infer live integration, authentication or cross-device persistence requirements unless requested, or invent universal CRUD or roles. Proposed mock data is not yet approval to implement it.

Be compact and complete. Explain only non-obvious trade-offs; no narrated reasoning or implementation plan.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
