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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.00184 |
| Opus 5.5 | $0.00007 | $0.00074 |
| Sonnet 5.5 | $0.00004 | $0.00037 |
| Haiku 4.5 | $0.00002 | $0.00018 |
Grade A, and why
dev-tdd 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
Follow the TDD cycle to implement the requested feature:
- Red — write a failing test that describes the expected behavior.
- Green — write the minimal code to make the test pass.
- Refactor — improve code quality without changing behavior (DRY, clear naming, proper abstractions).
- Run
npm testafter each cycle to confirm the test suite stays green. - Repeat for each unit of work until the feature is complete.
After all cycles:
- Run
npm run lintto catch style issues. - Run
npm run typecheckto confirm type safety. - Ensure proper separation of concerns — no god functions, no duplicated logic.
- If CLI behavior changed, run the command manually in an isolated workspace.
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.

dev-tdd is a command published in the GitHub repository Azure/azure-functions-skills (20 stars, last pushed yesterday), licensed MIT. It adds 18 tokens to every session and 184 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-09.

tdd
