writing-plans

writing-plans is a skill for Claude Code from DollarDill/beads-superpowers. It costs 21 tokens per session (3,361 once invoked), scanned A, original, MIT.

A guide for writing a detailed implementation plan from an existing specification before changing code. It explains which files, tests, documentation, and small tasks are needed, using TDD, meaning tests are written before the implementation.

In plain words
What is it for?
Use it to plan multi-step coding work, identify files to change, define tests, and save a dated plan for implementation.
Why use it?
It gives an engineer with little project context a step-by-step map and ensures every requirement is addressed or explicitly left out. It also records security and testing considerations.

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

writing-plans 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 11d 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.

Writing Plans

Overview

Write comprehensive implementation plans assuming the engineer has zero context for our codebase and questionable taste. Document everything they need to know: which files to touch for each task, code, testing, docs they might need to check, how to test it. Give them the whole plan as bite-sized tasks. DRY. YAGNI. TDD. Frequent commits.

Assume they are a skilled developer, but know almost nothing about our toolset or problem domain. Assume they don't know good test design very well.

Announce at start: "I'm using the writing-plans skill to create the implementation plan."

Production-Grade Doctrine: every spec requirement MUST map to a task — a deliberate cut is surfaced as a tracked decision, never a silent omission. Never weaken, bypass, or remove a security control — a security regression is never acceptable.

Context: This should be run in a dedicated worktree (created by brainstorming skill).

Save plans to: .internal/plans/YYYY-MM-DD-<feature-name>.md

  • (User preferences for plan location override this default)

Knowledge Check

Before writing tasks, query the knowledge store: bd list --label <topic> --status all + bd search "<keywords>" --status all + bd memories <keyword> (the memory half — lessons, patterns, root-causes; knowledge-beads alone miss it entirely). Then read — hits are pointers, not knowledge: bd show <id1> <id2> ... / bd recall <key> for every hit that plausibly bears on this plan. Emit KB check: N bead hits, M memory hits, K read plus a one-line disposition per read hit — folded into a task (which one) or ruled out (why).

Scope Check

If the spec covers multiple independent subsystems, it should have been broken into sub-project specs during brainstorming. If it wasn't, suggest breaking this into separate plans — one per subsystem. Each plan should produce working, testable software on its own.

File Structure

Before defining tasks, map out which files will be created or modified and what each one is responsible for. This is where decomposition decisions get locked in.

writing-plans is a skill published in the GitHub repository DollarDill/beads-superpowers (26 stars, last pushed 19d ago), licensed MIT. It adds 21 tokens to every session and 3,361 once invoked, about $0.0001 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.
