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 | $0.00875 | $0.00875 |
| Opus 5 | $0.00438 | $0.00438 |
| Sonnet 5 | $0.00175 | $0.00175 |
| Haiku 4.5 | $0.00088 | $0.00088 |
Grade B, and why
alphanana 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 9d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
alphanana
Single-package repo (pnpm, ESM-only, built with tsdown). Ships three ways from one source
tree: an npm library, an alphanana CLI, and a Claude Code plugin.
See README.md for what the difference-matte pipeline does and why it exists.
Commands
pnpm build # tsdown -> build/ (esm + .d.mts, no sourcemaps)
pnpm typecheck # tsgo -p tsconfig.json
pnpm lint # oxlint src test
pnpm test # vitest run
There is no aggregate check script — run pnpm lint && pnpm typecheck together.
Layout
src/matte.ts— the alpha solve (a = 1 - (white - black),F = black / a) and the guard stats that decide whether a matte is trustworthy. The only unit-tested module.src/gemini.ts— Gemini image model calls (render, then edit-to-black).src/generate.ts— one asset: render pair, matte, guard, re-roll on drift.src/variants.ts— N seeds of one subject, optional contact sheet.src/batch.ts— manifest-driven runs; writesassets.report.json.src/config.ts/src/env.ts—alphanana.jsonschema (zod) and.envdiscovery.src/cli.ts— arg parsing; progress to stderr, output paths to stdout.skills/alphanana/SKILL.md+.claude-plugin/— the Claude Code plugin. The skill drives the published CLI vianpx -y alphanana, so it is distributed through the plugin marketplace (git), never through the npm tarball.docs/— README assets only, outside thefileswhitelist so none of it ships.make-casts.mjsregenerates both terminal demos; see README > Development for thesvg-term-cliinvocations and the two manual post-edits it needs. The casts are hand-authored on purpose — a real recording would cost a paid generate run per tweak.
.claude-plugin/plugin.json carries its own version and is kept in lockstep with
package.json. npm version does not touch it — bump both, or the marketplace and the
npm package disagree.
Publishing
Automated. .github/workflows/publish.yml publishes to npm on every push to master
whose package.json version is not on the registry yet — so bumping the version is
what ships, and an ordinary commit is a no-op.
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.

alphanana CLAUDE.md is an instructions file published in the GitHub repository tobiasstrebitzer/alphanana (4 stars, last pushed 1mo ago), licensed MIT. It adds 875 tokens to every session, about $0.0044 per session on Opus 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.
