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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01571 | $0.01571 |
| Opus 5.5 | $0.00628 | $0.00628 |
| Sonnet 5.5 | $0.00314 | $0.00314 |
| Haiku 4.5 | $0.00157 | $0.00157 |
Grade A, and why
wherefore 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
@AGENTS.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What this repo is
A Claude Code plugin marketplace. It hosts the wherefore plugin, which ships five skills and a command for capturing technical decisions into a repo-committed wherefore log, querying them later, closing out open questions, retiring superseded or obsolete decisions, and tracking forward-looking plan items. The marketplace itself has no build system, tests, or runtime -- the only "code" is JSON manifests, Markdown skill/command definitions, and a GitHub Actions CI workflow.
Validation
# Validate a single plugin
claude plugin validate ./plugins/wherefore
# Validate the whole marketplace
claude plugin validate .
# Check JSON syntax (what CI does first)
python3 -m json.tool .claude-plugin/marketplace.json
python3 -m json.tool plugins/wherefore/.claude-plugin/plugin.json
CI (.github/workflows/validate-plugins.yml) runs both JSON checks and claude plugin validate on every push and PR.
Publishing / setup
Marketplace and plugin names must be kebab-case -- the Claude.ai sync rejects anything else.
To test locally before pushing:
# From this repo's root
/plugin marketplace add ./
/plugin install wherefore@dustinvk
Repo structure and how pieces fit together
.claude-plugin/marketplace.json # registry: lists plugins by name + source path
plugins/wherefore/
.claude-plugin/plugin.json # plugin manifest (name, version, author, license)
CLAUDE.snippet.md # pasted into a consuming project's CLAUDE.md to
# make Claude offer to capture decisions automatically
commands/seed.md # /wherefore:seed: inspects a codebase and proposes
# wherefore/topics.md vocabulary (ask-before-write)
skills/capture/
SKILL.md # captures a discussion into wherefore/ as one or
# more tagged Markdown entries; registers any open
# questions as questions/Q-NNN-short-slug.md files
topics.seed.md # starter vocabulary copied on first use if no
# topics.md exists yet
skills/ask/
SKILL.md # answers "why did we build X?" by shortlisting from
# entry frontmatter, then opening matching files;
# also surfaces open questions in the same area
skills/resolve/
SKILL.md # closes an open question by editing its
# questions/Q-NNN-short-slug.md file (answer, rationale, back-link)
skills/supersede/
SKILL.md # marks an entry superseded (with pointer to
# replacement) or obsolete via its frontmatter
skills/slate/
SKILL.md # manages wherefore/plan/ items (open, advance,
# drop, read): one verb, four intents; never
# writes log/ or questions/, hands off instead
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.

wherefore CLAUDE.md is an instructions file published in the GitHub repository DustinVK/wherefore (1 stars, last pushed 3mo ago), licensed MIT. It adds 1,571 tokens to every session, about $0.0063 per session on Opus 5.5. 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 2026-08-31.
