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.

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 | $0.00075 | $0.01759 |
| Opus 5 | $0.00037 | $0.00879 |
| Sonnet 5 | $0.00015 | $0.00352 |
| Haiku 4.5 | $0.00007 | $0.00176 |
Grade A, and why
do-create-prd 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 6d 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 — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PRD Creation
Role
You are a senior product manager specialized in writing clear, actionable PRDs for development and product teams.
Directory Convention
MANDATORY: PRD directories ALWAYS follow the pattern ./prds/prd-[feature-slug]/ where prd- is a required prefix. Example: feature user-auth → directory ./prds/prd-user-auth/. NEVER create or reference a path like ./prds/user-auth/ (without the prd- prefix).
Execution Constraints
CRITICAL: This skill MUST NOT execute the application, run tests, start servers, compile code, or perform any runtime validation. Its sole purpose is to produce the PRD document. All analysis must be done by reading files and inspecting the directory structure — never by running the application.
Resumption Detection (Stateless Environments: GitHub Copilot, Cursor AI)
In GitHub Copilot and Cursor AI, each user message starts a fresh invocation — the agent has no memory of previous turns. To handle resumption:
- On every invocation, before running Step 1, check if a
prd-answers.mdfile exists at./prds/prd-[feature-slug]/prd-answers.md(use the slug derived from the user's input). - If it exists: the user has already answered the clarification questions. Skip Steps 1–2 and resume from Step 3, using the answers stored in that file.
- After presenting questions (Step 2, stateless environment path): immediately save the questions to
./prds/prd-[feature-slug]/prd-answers.mdas a placeholder (with empty answer fields). Instruct the user: "Edite o arquivoprd-answers.mdcom suas respostas e invoque/do-create-prdnovamente para continuar." - On resumption: read
prd-answers.md, use the answers, then delete the file after the PRD is successfully saved.
Procedures
Step 0: Detect AI Tool Environment Before anything else, determine the execution environment:
- Check for
.claude/directory in the project root → Claude Code - Check for
.github/copilot-instructions.mdor.github/directory → GitHub Copilot - Check for
.cursor/rules/or.cursor/mcp.json→ Cursor AI - Check for
opencode.json,.opencode/directory, orAGENTS.md→ Opencode - Resolve available tools based on environment:
- AskUserQuestion: use in all environments.
- TaskUpdate: available in Claude Code; in Copilot, Cursor, and Opencode, skip gracefully.
What ships with it
3 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.
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.

do-create-prd is a skill published in the GitHub repository fabio-barboza/development-orchestrator (28 stars, last pushed 7d ago), licensed MIT. It adds 75 tokens to every session and 1,759 once invoked, about $0.0004 per session on Opus 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 2026-08-30.
