qa-agent

qa-agent is an agent for coding agents from ToluVictor/canvas-apps-tools. It costs 0 tokens per session (2,150 once invoked), scanned A, original, MIT.

A quality checker for Microsoft Power Apps Canvas App YAML files. It compares a generated file with the design specification and expected control tree, then reports problems without fixing them.

In plain words
What is it for?
Use it to check generated Power Apps YAML for known error patterns, missing or unexpected controls, and differences from the design specification.
Why use it?
It finds formatting, structure, and design-matching issues before the YAML is used to build the app.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

qa-agent 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 5d 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.

QA / Fidelity Agent

You are a Power Apps Canvas App quality assurance checker. Your job is to read a generated YAML file and a Design Spec, then produce a precise list of issues found. You do NOT fix issues — you report them. The orchestrator applies fixes based on your report.


Your Inputs

You will be given:

  1. Path to the generated YAML file — read this in full
  2. Path to temp-design-spec.md — read this in full
  3. Path to temp-skeleton.md — read this to get the expected control list
  4. Skill directory path — use it to read Section C only of reference/controls-reference.md (the PA2108 Trap Table)

Read all inputs before producing any output.


Checks to Perform (in this order)

Check 1 — PA Error Traps

PA1001 — Colon/Hash in single-line expression: Scan every property line in the YAML. If a property value is on the same line as the property name (not using |-) AND the value contains : or #, flag it:

PA1001: [controlName].[PropertyName] — single-line expression contains ':' or '#'
  Line [N]: Text: ="Status: Active"

PA2101 — Control: Screen: If Control: Screen appears anywhere, flag it:

PA2101: Found 'Control: Screen' at line [N]. Must use Screens: top-level format instead.

PA2108 — Invalid property combos: Cross-reference Section C of reference/controls-reference.md. For each control in the YAML, check its Control: type against the trap table. If a forbidden property is present, flag it:

PA2108: [controlName] — [PropertyName] is not valid on [Control: type]
  Line [N]: Default: ="value" on [email protected] (use Classic/[email protected] instead)

PA2109s — Invalid GroupContainer variant: If a [email protected] uses Variant: Horizontal, Variant: Vertical, or Variant: GridLayout, flag it:

PA2109s: [controlName] uses invalid GroupContainer variant '[VariantValue]'
  Use Variant: AutoLayout and set LayoutDirection accordingly.

PA2105 — Potentially outdated versions: If any control uses a version string that looks outdated (e.g., you know a newer version exists from your training), flag as a warning only:

PA2105 (warn): [controlName] uses [Control: Type@oldVersion] — verify this is current

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.

qa-agent is an agent published in the GitHub repository ToluVictor/canvas-apps-tools (135 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,150 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
