cy-create-techspec

A guided tool for turning a product requirements document (PRD) into a technical specification. A PRD describes what a product should do, while a technical specification explains how software should be built.

In plain words
What is it for?
Use it to document implementation designs from existing business requirements and to clarify technical choices with an interactive design review.
Why use it?
It helps resolve technical questions and record architecture decisions before coding starts, including for changes that may appear small.

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

cy-create-techspec 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 2d 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 — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create TechSpec

Translate business requirements into a detailed technical specification.

Asking Questions

When this skill instructs you to ask the user a question, you MUST use your runtime's dedicated interactive question tool — the tool or function that presents a question to the user and pauses execution until the user responds. Do not output questions as plain assistant text and continue generating; always use the mechanism that blocks until the user has answered.

If your runtime does not provide such a tool, present the question as your complete message and stop generating. Do not answer your own question or proceed without user input.

Anti-Pattern: "This Is Too Simple To Need Technical Design Review"

Every TechSpec goes through the full design review process. A single endpoint, a minor refactor, a configuration change — all of them. "Simple" technical changes are where unexamined assumptions about existing architecture cause the most integration failures. The design review can be brief for genuinely simple changes, but you MUST ask technical clarification questions before writing the artifact.

Anti-Pattern: End-Of-Flow Bureaucracy

Once the user has answered the technical clarification questions, do not force them through a draft-approval loop before writing. Record the decisions as ADRs, synthesize the TechSpec, and write the file directly. The user reviews the generated file and requests edits afterward if needed.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
