superspecs: Skill for Claude Code

.skills/verify-wiki/SKILL.md

verify-wiki is a skill for Claude Code, Codex from fokkerone/superspecs. It costs 75 tokens per session (2,259 once invoked), scanned A, original, MIT.

A project-documentation tool that records the important knowledge from a completed and tested feature in a linked project wiki. The wiki is a collection of Markdown pages that can also be opened in Obsidian, a note-taking app.

In plain words
What is it for?
It helps document how a feature works, why key decisions were made, important interfaces, known pitfalls, and questions left for later.
Why use it?
It prevents architecture choices, design patterns, trade-offs, and hard-won fixes from being lost when a work session ends.

Written for no agent in particular: nothing here depends on one.

This is fokkerone/superspecs's own configuration. It tells Claude Code and Codex 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

verify-wiki 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 8d 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.

Skill: verify-wiki

You are distilling the completed feature into the living project wiki.

The feature works. The tests pass. Now you extract the knowledge that should survive beyond this session — so future planning, future features, and future sessions start informed.

The wiki lives at superspec/wiki/ and doubles as an Obsidian vault. Write every page to be navigable in Obsidian: use [[wikilinks]] for internal links, YAML frontmatter with tags:, and keep each page focused on a single knowledge unit.

What to distill (and what not to)

Distill:

  • Architecture decisions (what was chosen and why)
  • Patterns discovered or established
  • Trade-offs made (what was given up, what was gained)
  • Gotchas (things harder than expected + how they were solved)
  • Key interfaces / contracts / data shapes
  • Open questions deferred to future work

Do NOT copy:

  • Full code listings (reference file paths instead)
  • Task checklists or execution logs
  • The full spec (it lives in superspec/specs/)

Provenance

Mark the origin of every claim so future readers know what is fact vs. synthesis:

  • Default (no marker): directly extracted from source material
  • ^[inferred] — synthesized by the agent; not stated verbatim in sources
  • ^[ambiguous] — sources disagree or the claim is uncertain

Example:

The team chose Redis over Postgres for session storage because of latency requirements.
A TTL of 15 minutes was selected as the balance point. ^[inferred]
Note: the DISCUSS.md mentions 10 minutes but the spec says 15 — see review-log. ^[ambiguous]

Steps

1. Gather the source material

Read:

  • superspec/specs/<slug>/DISCUSS.md
  • superspec/specs/<slug>/spec.md
  • superspec/phases/<slug>-execute/review-log.md
  • The implementation itself (key files touched)

2. Scan existing wiki pages first

Before writing anything new, scan the existing wiki for related content.

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.
