Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00224 | $0.00224 |
| Opus 5 | $0.00112 | $0.00112 |
| Sonnet 5 | $0.00045 | $0.00045 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
mcpick copilot-instructions.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 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.
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.
What it actually says
MCPick Development Instructions
Project shape
MCPick is a vendor-neutral MCP configuration manager with first-class Claude Code support.
- Keep MCP server functionality client-neutral where possible.
- Keep Claude Code plugins, hooks, marketplaces, and cache commands clearly Claude-specific.
- Prefer CLI flows that work well for LLM agents: non-interactive
flags,
--json, useful help text, and redacted output.
Prerequisites
- Node.js >=22.0.0
- pnpm
Common commands
pnpm install
pnpm test
pnpm run check
pnpm build
Validation before finishing
Always run:
pnpm run check
pnpm test
pnpm build
pnpm run check validates formatting, lint, and types through
vite-plus.
Changesets
For user-facing changes, add a changeset:
pnpm changeset
Use a short message prefixed with feat, fix, chore, or
breaking.
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.
