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 | $0.00050 | $0.00955 |
| Opus 5 | $0.00025 | $0.00477 |
| Sonnet 5 | $0.00010 | $0.00191 |
| Haiku 4.5 | $0.00005 | $0.00096 |
Grade A, and why
prd-writer 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 10d 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.

PRD Writer Skill
Generate a complete, structured PRD from a feature idea, problem statement, or brief description.
When to Use
- User needs to write a PRD for a new feature
- User has an idea and wants it turned into a structured spec
- User says
/prd-writerfollowed by a feature description - Any time a product requirement needs to be documented
Framework: PRD Structure
1. Overview
- Feature name: Clear, descriptive name
- Author: [to be filled]
- Date: Current date
- Status: Draft / In Review / Approved
- One-liner: What this feature does in one sentence
2. Problem Statement
- What problem are we solving? Describe the user pain point or business need
- Who has this problem? Primary user segment
- How big is this problem? Estimated impact (users affected, frequency, severity)
- Why solve it now? Urgency, strategic alignment, competitive pressure
3. Goals & Non-Goals
Goals:
- 3-5 specific, measurable goals this feature should achieve
- Each goal maps to a user need or business objective
Non-Goals:
- Explicitly list what this feature will NOT do
- Prevents scope creep and sets expectations
4. User Stories
Write 3-5 user stories in the format:
As a [user type], I want to [action] so that [benefit].
Include acceptance criteria for each:
- Given [context], when [action], then [expected result]
5. Detailed Requirements
Functional Requirements:
| ID | Requirement | Priority (P0/P1/P2) | Notes |
|---|---|---|---|
| FR-1 | |||
| FR-2 |
Non-Functional Requirements:
- Performance: Latency, throughput, scalability targets
- Security: Auth, data handling, compliance
- Accessibility: WCAG level, screen reader support
- Reliability: Uptime, error handling, graceful degradation
For AI/ML features, also include:
- Model requirements: Accuracy, latency, cost per inference
- Data requirements: Training data, eval data, data pipeline
- Safety requirements: Content policy, guardrails, fallback behavior
- Eval criteria: How model quality will be measured
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.
- 10d ago First seen · 104 lines · 50 tokens per session scan A d3f06f295b32
prd-writer is a skill published in the GitHub repository aroyburman-codes/pm-skills (25 stars, last pushed 6mo ago), licensed MIT. It adds 50 tokens to every session and 955 once invoked, about $0.0003 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.

prd-taskmaster
Zero-config goal-to-tasks engine (the Atlas engine). Takes any goal (software, pentest, business, learning), runs adaptive discovery via brainstorming, generates a validated spec, parses into TaskMaster tasks, and hands off to execution. Use when user says "PRD", "product requirements", "I want to build", invokes…
generate
Phase 2 of the prd-taskmaster pipeline: spec generation and task parsing. Loads a template (comprehensive|minimal), fills it with DISCOVER-phase constraints and answers, validates the spec (placeholdersfound, grade thresholds), parses the PRD into tasks via task-master, runs TaskMaster's native complexity analysis…
discover
Phase 1 of the prd-taskmaster pipeline: brainstorm-driven discovery. Delegates to superpowers:brainstorming in Interactive Mode (one adaptive question at a time), or self-brainstorms in Autonomous Mode when no user is present. Intercepts before the brainstorming chain hands off to writing-plans — this skill owns the…
