.github/prompts/skill-dev.prompt.md

skill-dev is a command for GitHub Copilot from Azure/azure-functions-skills. It costs 13 tokens per session (180 once invoked), scanned A, original, MIT.

A workflow for creating and validating a new skill, including its instructions, supporting references, generated package data, and checks.

In plain words
What is it for?
It is for scaffolding a skill, adding reference material, running validation and full checks, rebuilding its plugin payload, and optionally adding an evaluation.
Why use it?
It provides a repeatable path through setup, editing, validation, packaging, and final verification instead of leaving those steps easy to miss.

About the project

Azure Functions Skills is a repository of agent skills, prompts, reusable definitions, MCP configuration, and telemetry hooks that give coding agents context about Azure Functions development and operations. Developers use it for guidance on triggers, bindings, runtimes, deployment, and code checks, while the catalogue contains its agent-facing add-ons.

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

skill-dev 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 1mo 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.

What it actually says

Create a new skill following the established workflow:

  1. Scaffold: npm run new:skill and follow the prompts.
  2. Edit templates/skills/<skill-name>/SKILL.md — write clear, unambiguous instructions.
  3. Add supporting material in references/ (checklists, examples, patterns).
  4. Validate: npm run validate:skills
  5. Regenerate plugin payload: npm run build:plugin-payload
  6. Verify payload consistency: npm run verify:plugin-payload
  7. Run full gate: npm run check
  8. Try the skill manually with a coding agent and check the quality of the task result.

Review the skill content carefully — it will be loaded as LLM agent instructions with elevated permissions.

Changes

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.
