What is tskills AGENTS.md?

A project instruction file for tskills, a package manager for AI skills that supports several coding tools and includes local, registry, organization, and team commands.

Use it when developing or testing tskills and its commands for skills, registries, organizations, teams, and tool-specific outputs.

It tells coding agents how to install dependencies, build, run, link, and navigate the TypeScript project.

Token cost

What it costs to keep this loaded

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	$0.01074	$0.01074
Opus 5.5	$0.00430	$0.00430
Sonnet 5.5	$0.00215	$0.00215
Haiku 4.5	$0.00107	$0.00107

Security

Grade A, and why

tskills AGENTS.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 2mo 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.

Project Structure

src/cli.ts - Entry point, registers all commands (local + registry + org/team)
src/types.ts - TypeScript interfaces for skills, registry, orgs, teams, auth
src/commands/ - Each file is a CLI command:
- Registry: login, logout, whoami, publish, install, uninstall, search, info, outdated, update, deprecate
- Organizations/Teams: org (subcommands: create, list, info, add, remove, delete), team (same subcommands)
- Local/Legacy: setup, init, add, import, list, sync, share, config
src/adapters/ - Tool-specific output adapters (Claude, Cursor, Windsurf)
src/lib/ - Shared utilities:
- config.ts - Read/write ~/.tskills/config.toml
- discover.ts - Auto-discover SKILL.md files
- git.ts - Clone/pull operations
- skill.ts - Parse SKILL.md with YAML frontmatter
- credentials.ts - Auth token storage (~/.tskills/credentials.json)
- errors.ts - Custom error classes (Auth, Network, Validation, RateLimit, Permission, etc.)
- error-handler.ts - Maps Supabase/Postgres/FS errors to custom errors
- manifest.ts - Tracks installed skills (~/.tskills/installed.json)
- registry.ts - Supabase client + full registry API (~1000 lines)
- registry-config.ts - Dynamic registry config with remote fetch + caching
- retry.ts - Retry with exponential backoff and jitter
- validation.ts - Input validation (skill names, semver, slugs, usernames)
supabase/ - Supabase project config and 14 SQL migrations

Backend (Supabase)

The registry backend is a Supabase project with:

Postgres tables: users, skills, skill_versions, organizations, org_members, teams, team_members, rate_limits
Row Level Security (RLS): visibility-based access control (public/private/org/team)
RPC functions: check_rate_limit, increment_downloads, create_org_with_owner
GitHub OAuth for authentication

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.
