Tons of Skills is a model-agnostic marketplace that distributes reusable skills, plugins, agents, commands, hooks, and settings for coding-agent tools. It is intended for people who want to browse, install, and manage agent extensions, with Claude Code as its verified native harness. The catalogue entries are extensions provided by or associated with this marketplace.

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 | $0.11645 | $0.11645 |
| Opus 5.5 | $0.04658 | $0.04658 |
| Sonnet 5.5 | $0.02329 | $0.02329 |
| Haiku 4.5 | $0.01165 | $0.01165 |
Grade A, and why
tons-of-skills-marketplace CLAUDE.md scanned grade A 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Repository Overview
Tons of Skills — Claude Code plugins marketplace. Live at https://tonsofskills.com
Runtime: Node >=22.12.0, pnpm >=9.15.9. The Astro marketplace build requires Node 22.12+. Node 18 causes silent workspace-resolution failures. Package-local lower floors remain valid only for independently run packages that do not enter the repository build or verification path; see 000-docs/814-DR-STND-node-runtime-contract.md.
Package manager: pnpm everywhere except marketplace/ which uses npm (CI-enforced).
Contributor guidelines live in AGENTS.md — project structure, build/test/dev commands, style and naming, test conventions, commit/PR expectations, and the merge gates. Read it before starting work. (Session protocol lives in this file: the beads workflow in § Beads Issue Tracker — where bd prime is also the post-compaction context-recovery step — and the end-of-session push checklist in § Session Completion.)
Cross-session coordination — another Claude session may be in this repo
This repo is frequently worked in parallel with the intent-eval-platform umbrella session (that platform's CCPI validator + jrig-cli + kernel reach into this repo). Sessions are separate processes that share only the filesystem, so stay in sync via the shared surfaces:
- Read + append the shared journal on cross-repo work:
~/000-projects/CROSS-SESSION-LOG.md(append a dated line: what / branch or PR# / status). - Durable cross-cutting tasks: umbrella beads
~/000-projects/.beads/, labelcross-session(bd list --label cross-session). - Guard the working tree: this repo has ONE checkout; a concurrent session can
git checkout/resetit out from under you and wipe UNCOMMITTED work (happened 2026-07-01). Commit early, or do multi-step file work in agit worktree.
Full protocol (loaded by every session under /home/jeremy): /home/jeremy/CLAUDE.md § "Cross-session coordination".
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.
