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 | $0.06959 | $0.06959 |
| Opus 5.5 | $0.02784 | $0.02784 |
| Sonnet 5.5 | $0.01392 | $0.01392 |
| Haiku 4.5 | $0.00696 | $0.00696 |
Grade B, and why
alexmskills CLAUDE.md scanned grade B with 1 finding 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 16d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

alexmskills
A public Claude Code plugin marketplace of reusable, self-improving skills and agents. Each skill is an independently versioned plugin. This file is the project's working memory; the README is the public front door.
Layout
.claude-plugin/marketplace.json # the catalog — every plugin + its source/version
plugins/<name>/ # one directory per plugin
.claude-plugin/plugin.json # manifest (name, version, author, …)
skills/<skill>/SKILL.md # one or more skills
agents/<agent>.md # subagents (review-agents, dev-crew)
hooks/hooks.json # plugin-shipped hooks (evolving-claude-md)
docs/ # Antora component → published at alexmond.org/alexmskills
scripts/validate-marketplace.sh # jq-based validator (also run in CI)
Makefile # validate / list / bump helpers
.claude/ # per-plugin state (mindmap, prompt-coach, skill-linter)

Conventions
- One skill = one plugin, unless skills are tightly coupled (then bundle + version them together,
like
maven-quality). This is what makes per-skill versioning possible at all. - Every
plugin.jsoncarries the same metadata shape:name,description,version(semver),author(Alex Mondshain / [email protected]),homepage,repository,license: MIT,keywords. ThenameMUST match itsmarketplace.jsonentry. - Bump versions with
make bump PLUGIN=<n> VERSION=<x.y.z>soplugin.jsonandmarketplace.jsonnever drift. Validate withclaude plugin tag --dry-run plugins/<n>. - Run
make validatebefore committing. CI runs it too. - Skills must be project-agnostic. No hardcoded absolute paths, usernames, or repo names — these are pulled FROM other repos and generalized; keep them that way.
- Docs are part of "done": a new plugin needs a
docs/modules/ROOT/pages/<n>.adocpage, anav.adocentry and a row onindex.adoc; every version bump gets aCHANGELOG.mdentry (grouped by date, tagged with plugin + version).make validateenforces all three — it was a convention until the landing page drifted four plugins behind the catalog. - Plugin naming: orchestrators are
<scope>-<team-noun>, the team-noun encoding coordination (crew= handoff/deliver,panel= debate/decide,sweep= fan-out/discover); other skills are descriptive kebab-case, verb-first for actions, ≤3 words, no redundant qualifiers. - Role naming: a role is named for the persona (a noun — who they are), never the task (a verb
— what they do), so it reads right seated solo, in a crew, on a panel, or in a sweep. Coverage roles
use
<dimension>-scout. Role names are shared across orchestrators (oneskeptic, onearchitect). - Never push or cut release tags without explicit user confirmation.
- Attribution: all plugins are original work by the author (MIT, per plugin.json
author); the roles-plugin personas credit@nahidulislam404's prompt thread as inspiration. This is a public-repo provenance note; don't drop it in a cleanup.
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.

alexmskills CLAUDE.md is an instructions file published in the GitHub repository alexmond/alexmskills (10 stars, last pushed 16d ago), licensed MIT. It adds 6,959 tokens to every session, about $0.0278 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
