superspecs: Instructions file for Claude Code

CLAUDE.md

superspecs CLAUDE.md is an instructions file for Claude Code from fokkerone/superspecs. It costs 462 tokens per session, scanned A, original, MIT.

A set of instructions for a coding workflow that moves through planning, execution, verification, and shipping. TDD means writing a failing test first, then the smallest code change that makes it pass, followed by cleanup.

In plain words
What is it for?
It is for discussing and stress-testing requirements, executing work in separate branches or worktrees, assigning tasks to fresh subagents, running tests, reviewing code, and preparing a pull request.
Why use it?
It gives development work defined checkpoints and requires specifications, review, test evidence, and documentation before shipping.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions subagents; mentions Claude Code.

This is fokkerone/superspecs's own configuration. It tells Claude Code how to work on superspecs itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything superspecs configures →

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

superspecs CLAUDE.md 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 7d 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.

What it actually says

SuperSpecs — Claude Code

You have SuperSpecs installed. Four phases, always in order.

The Lifecycle

PLAN → EXECUTE → VERIFY → SHIP

Phase 1: Plan

  1. /discuss — Capture decisions, goals, non-goals, constraints BEFORE any spec is written
  2. /spec — Write the spec (SHALL requirements + GIVEN/WHEN/THEN scenarios) — requires DISCUSS.md
  3. /grill — Stress-test the spec. Mandatory gate. READY verdict required before execution. — requires spec.md

Exit gate: Spec grilled to READY. Too big = decompose and re-grill.

Phase 2: Execute

  1. /pick-spec — Confirm spec is complete and context-window-fit
  2. /branch — Create git branch or worktree (one per spec)
  3. /subagent — Dispatch fresh subagent per task; two-stage review per task
  4. /tdd — RED → GREEN → REFACTOR. Write failing test. Watch it fail. Write minimal code. Watch it pass. Commit. Delete any code written before tests.
  5. /code-review — Runs between tasks. Critical issues BLOCK progress.

Phase 3: Verify

  1. /verify — Full suite + scenario coverage (Stage 1), then distill to knowledge base (Stage 2). Gate: tests must pass before wiki import runs.

Phase 4: Ship

  1. /ship — PR + changelog + archive + start next cycle.

Hard Rules

  • Never write implementation code before a failing test exists
  • Never proceed past a Critical code review finding
  • Never skip /discuss — decisions captured late are decisions lost
  • Never skip /grill — a spec that hasn't been grilled to READY blocks /pick-spec
  • Never declare done without /verify passing
  • Every shipped feature gets a wiki page

Paths

  • superspec/specs/ — Specs and discussion docs
  • superspec/phases/ — Active execution working dirs
  • superspec/wiki/ — Living knowledge base
  • .skills/ — Skill definitions
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.
