tbm-plugin

tbm-plugin is a skill for Claude Code, Codex from Far-Se/tabame. It costs 74 tokens per session (1,830 once invoked), scanned A, original, MIT.

A guide to writing Tabame launcher plugins: standalone Python, Node.js, or Bun scripts that extend the app's search launcher.

In plain words
What is it for?
Use it to create, install, or debug a plugin that responds to a launcher keyword. The script exchanges newline-separated JSON messages with Tabame through standard input and output.
Why use it?
It explains the exact message format needed for a script and prevents inventing unsupported fields or communication rules.

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.

Security

Grade A, and why

tbm-plugin 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.

Makes network callslowCapability

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

The plugin is an ordinary process: HTTP (`requests`/`urllib`, or global `fetch` in Node 18+/Bun), filesystem, spawning tools. Read secrets from a `config.json` in the plugin folder (the CWD) or env vars — see `plugins/li

The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Tabame Launcher Plugin Authoring

Tabame's launcher is extensible with plugins: standalone scripts (Python, Node.js, or Bun) that Tabame runs as a long-lived child process when the user types the plugin's keyword. Communication is newline-delimited JSON over stdin/stdout — no SDK, no dependencies.

  • Tabame → script (stdin): UI events (init, query, select, action, close).
  • Script → Tabame (stdout): render frames — JSON objects that fully describe what the launcher shows right now.

The script is the source of truth for the UI: every time you want the launcher to display something different, you print a new render frame.

Authoritative references (read these)

The complete, authoritative protocol spec lives in the repo. Read it before writing non-trivial plugins — do not invent fields or message types not documented there:

  • Full spec: skills/TABAME_PLUGIN_SKILL.md — every message type, render-frame field, item field, view type, icon name, and pattern.
  • Working examples to copy from:
    • plugins/echo/ — Python demo exercising list/grid/detail/preview + actions.
    • plugins/linear/ — Node.js plugin with an HTTP API and config.json secrets.
    • plugins/caniuse/ — Node.js plugin with fetched data and detail views.

When a detail isn't covered below, consult the full spec rather than guessing.

Workflow for building a plugin

  1. Clarify the shape (only if unspecified): keyword, runtime, data source, what each item shows, what Enter does, what Ctrl+K actions to offer, and which view (list / grid / detail / preview pane).
  2. Pick a runtime the user has on PATH: python, node (18+), or bun. Tabame bundles none.
  3. Scaffold the folder with plugin.json + entry script. Start from the matching template in §15 of the full spec, or copy the closest plugins/ plugin.
  4. Implement the event loop (see contract below).
  5. Install & test: drop the folder in %localappdata%\Tabame\plugins\<id>\, reopen the launcher (it rescans on every open — no restart), and type the keyword.

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.

tbm-plugin is a skill published in the GitHub repository Far-Se/tabame (366 stars, last pushed 2d ago), licensed MIT. It adds 74 tokens to every session and 1,830 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
