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 | $0.19196 | $0.19196 |
| Opus 5.5 | $0.07678 | $0.07678 |
| Sonnet 5.5 | $0.03839 | $0.03839 |
| Haiku 4.5 | $0.01920 | $0.01920 |
Grade B, and why
agent-skill-manager AGENTS.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 24d 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.
Plugin enable/disable is out of scope for MVP. A future `Plugins` screen may toggle whole Claude plugins through `~/.claude/settings.json.enabledPlugins`, but the first `Skills` screen must not do that. How it starts
The opening of the file, as written. The whole thing — 1,528 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Manager Agent Brief
Project Intent
skill-manager is a local tool for managing globally installed agent skills for Claude Code, Codex, Muse, and Grok. Its established terminal interfaces remain the primary source-management surface, with a macOS desktop interface for visibility and reversible toggles.
The first version is a local, simple, reversible TUI plus a minimal CLI. It must make it easy to see which skills are enabled for each tool and toggle them off and on without losing their original installation method.
This repository is intentionally greenfield. The planning discussion happened before implementation. Preserve these decisions unless the user explicitly changes them.
Public Text
This repository is public. Pull request bodies, commit messages, issues,
docs, wiki, plans, and fixtures describe behavior for every user with synthetic
examples. Review that public text with
docs/contributing/public-text.md before
git push and before creating or editing a pull request, issue, or release.
Mandatory Wiki Routing
This project has an LLM-maintained wiki under docs/wiki/.
Before starting non-trivial work in this repository:
- Read
docs/wiki/README.mdfor the wiki contract, source precedence, and workflows. - Read
docs/wiki/index.md, then open the topic pages relevant to the task. - Verify important or mutable claims against the authoritative project files; the wiki is a synthesis layer, not a replacement for this file, the planning documents, code, or tests.
After work that produces a reusable conclusion, correction, decision, implementation insight, or open item, update the relevant docs/wiki/topics/ or docs/wiki/sources/ pages, update docs/wiki/index.md when pages change structurally, and append an entry to docs/wiki/log.md using ## [YYYY-MM-DD] type | Short title.
If the user accepts a change to product scope, semantics, paths, or UX, update the authoritative files required by the Documentation Rules below before bringing the wiki synthesis up to date.
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.
