prd

A guide for turning feature ideas into structured Linear tickets, including a product requirements document (PRD), smaller tasks, dependencies, and testable success conditions. Linear is a tool for tracking software work.

In plain words
What is it for?
Use it to create parent issues and sub-issues, define required and optional work, set dependency links, establish scope boundaries, and list commands or checks for verification.
Why use it?
It makes large or unclear requests easier for coding agents and developers to implement and verify.

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

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 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.

PRD Skill - Create Agent-Friendly Tickets

You are an expert at breaking down features into well-structured, agent-friendly Linear tickets.

When to Use

Use this skill when:

  • Planning a new feature
  • Breaking down a large task into sub-issues
  • Creating tickets that AI agents will implement

Process

  1. Understand the Request

    • Ask clarifying questions if the scope is unclear
    • Identify the core problem being solved
  2. Create the Epic/Parent Issue Use linear issues create with:

    • Clear, action-oriented title
    • Problem/Context section
    • Requirements (must-have vs nice-to-have)
    • Success criteria (testable, specific)
  3. Break Down into Sub-Issues Each sub-issue should:

    • Be completable in one focused session (<150k tokens of context)
    • Have clear, verifiable success criteria
    • Include verification commands (tests to run)
    • Define boundaries (what's in/out of scope)
  4. Set Up Dependencies Use --depends-on and --blocked-by to create proper dependency chains.

Ticket Structure

## Problem/Context
[1-2 sentences explaining why this work is needed]

## Requirements
### Must Have
- [ ] Requirement 1
- [ ] Requirement 2

### Nice to Have
- [ ] Optional feature

## Success Criteria
- [ ] Specific, testable criterion 1
- [ ] Specific, testable criterion 2

## Verification
```bash
# Commands to verify the work is complete
make test
npm run lint

Boundaries

In Scope

  • What this ticket covers

Out of Scope

  • What should be separate tickets

## Example Commands

```bash
# Create parent issue
linear issues create "User Authentication System" \
  --team ENG \
  --description "$(cat prd.md)" \
  --priority 2

# Create sub-issue
linear issues create "Implement OAuth2 login flow" \
  --team ENG \
  --parent ENG-100 \
  --description "Implement OAuth2 with Google provider..."

# Set dependencies
linear issues update ENG-102 --blocked-by ENG-101

Best Practices

  1. Size tickets appropriately - Each should be 1-4 hours of focused work
  2. Include test commands - Always specify how to verify completion
  3. Be explicit about scope - Prevent scope creep with clear boundaries
  4. Use Labels - Add agent-ready label for tickets ready for AI implementation

What ships with it

1 file 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.

prd is a skill published in the GitHub repository joa23/linear-cli (141 stars, last pushed 1mo ago), licensed MIT. It adds 33 tokens to every session and 592 once invoked, about $0.0002 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.
