prd-to-tasks

prd-to-tasks is a skill for Claude Code, Codex from lukedj78/dev-flow. It costs 175 tokens per session (1,930 once invoked), scanned A, original, MIT.

A tool that turns a product requirements document, or PRD, into an ordered checklist of small development tasks. A PRD describes what a product or feature should do, while the checklist breaks that plan into work items.

In plain words
What is it for?
Use it when a project has a .workflow/PRD.md and you need a .workflow/tasks.md file with checkable tasks grouped by user story or epic.
Why use it?
It makes a broad feature plan easier to assign, estimate, track, and implement without manually splitting it into tickets.

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-to-tasks 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 5d 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-to-tasks — PRD.md → executable task list

This skill turns a PRD into a flat, ordered list of tasks small enough to be picked up by a developer or an AI executor. The output is .workflow/tasks.md — Markdown with - [ ] checkboxes — designed to be:

  • Readable by humans as a project punch-list.
  • Importable into beads (the gstack convention), GitHub Issues (one task per issue), or fed to ralph-tui as the task source.
  • Pushable to Linear via the linear-scrum skill (Setup mode), which reads tasks.md through the Linear MCP and creates one issue per task — not a CSV import.
  • Atomic enough that each line items represents 2–8 hours of work for a typical developer (or one focused session for an AI agent).

When this skill applies

  • A .workflow/PRD.md exists and phase is prd_drafted.
  • The user asks to "make the issues", "split the PRD", "create the task list", "ticket this".
  • The orchestrator routes here from prd_drafted (optional next step before scaffolding).

If .workflow/tasks.md already exists, enter revise mode: read the existing tasks and propose specific edits (add, remove, re-order, re-size) rather than overwriting.

Contract

This skill follows the dev-flow contract — see references/contracts.md for the canonical schema. Key facts:

  • Reads <root>/.workflow/PRD.md (mandatory) and .workflow/PROJECT.md (for stack/audience context).
  • Writes <root>/.workflow/tasks.md.
  • Sets phase = "tasks_split" on success (only if current phase is earlier in the enum).

Workflow

Step 1 — Read inputs and decide structure

Read .workflow/PRD.md. Extract:

  • The list of user stories (As a … I want … so that …).
  • The acceptance criteria for each story.
  • Any non-goals (these become negative tasks: explicit "do NOT do X" notes, not work items).
  • Technical constraints (e.g., "must use Postgres" → tasks like "set up Drizzle + Neon" go on the list early).

Group tasks into epics when there are 3+ user stories. With fewer stories, keep a flat list.

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.
