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 | $0.01531 | $0.01531 |
| Opus 5 | $0.00766 | $0.00766 |
| Sonnet 5 | $0.00306 | $0.00306 |
| Haiku 4.5 | $0.00153 | $0.00153 |
Grade A, and why
solopreneur 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 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.
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 — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This repo ships seven sub-plugins from a single marketplace:

Each directory name matches its marketplace name 1:1. The Depends on
column comes from src/<name>/plugin.json.
skills/ and src/ are the only hand-maintained plugin sources. Run
scripts/generate-plugin-packages.sh after changing either root. It rebuilds
the committed install packages at plugins/claude/<name>/ and the
registry-filtered plugins/codex/<name>/; never edit those outputs directly.
Config layering
The solopreneur plugin's user config (solopreneur.json) supports
per-repo overrides over a shared default. Skills read via
read_solopreneur_config <feature> which walks five layers, first
non-null wins:
- primary
repos[<repo-key>].<feature>— per-repo override - primary
default.<feature>— user-global default - fallback
repos[<repo-key>].<feature>— shared per-repo (rare) - fallback
default.<feature>— shared default - legacy top-level
<feature>— old flat-schema compatibility
<repo-key> is normalized from git remote get-url origin
(host/owner/repo); the helper falls back to the git toplevel path or
$PWD when no origin exists. Writes go through one of two helpers —
write_solopreneur_config lands at default.<key>,
write_solopreneur_repo_config lands at repos[<repo-key>].<key>.
Existing configs on the old flat schema ({ "todos": {...} } at the
top level) keep working via layer 5; migration is optional. The helpers
are implemented once in src/solopreneur/shared/config.sh, which
skills source; see src/solopreneur/shared/config.md for the
cascade documentation and a sample migrated config.
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.
