What is cpm CLAUDE.md?

A set of project instructions for cpm, a terminal application that manages Claude Code plugins.

Use it when developing cpm to format, test, lint, inspect, build, or run its Go terminal interface.

It records the project’s layout, architecture, required tools, and standard commands so contributors can work consistently.

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	$0.01012	$0.01012
Opus 5.5	$0.00405	$0.00405
Sonnet 5.5	$0.00202	$0.00202
Haiku 4.5	$0.00101	$0.00101

Security

Grade A, and why

cpm 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 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.

cpm - Claude Plugin Manager

Last verified: 2026-02-27

A TUI application for managing Claude Code plugins with clear visibility into installation scopes.

Quick Start

mise install        # Install tools (Go, golangci-lint, gofumpt, lefthook)
lefthook install    # Set up git hooks
mise run build      # Build the application
./cpm               # Run the application

Project Structure

cmd/cpm/           # Application entry point
internal/
  claude/          # Claude CLI client (see internal/claude/CLAUDE.md)
  tui/             # Bubble Tea TUI (see internal/tui/CLAUDE.md)
  version/         # Version info (injected at build time)

Development Commands

mise run fmt       # Format code with gofumpt
mise run lint      # Run golangci-lint
mise run vet       # Run go vet
mise run test      # Run tests
mise run build     # Build binary
mise run ci        # Run all checks

Or use Make: make fmt, make lint, make test, make build, make ci

Architecture

Flat model architecture: Single Model struct contains all TUI state
Bubble Tea: TUI framework using Elm Architecture (Model-Update-View)
Lip Gloss: Terminal styling and layout
Claude CLI: All plugin operations shell out to claude plugin commands

See docs/architecture.md for detailed diagrams and type definitions.

Maintaining Architecture Documentation

When making structural changes (new types, packages, or significant refactors):

Update docs/architecture.md with any new/changed types or relationships
Update the "Last updated" date at the top

Use LSP documentSymbol operation to extract current type definitions:

LSP documentSymbol on internal/claude/types.go, client.go, manifest.go
LSP documentSymbol on internal/tui/model.go, styles.go, keys.go

Ensure Mermaid diagrams reflect current structure

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.
