trello-beads

trello-beads is a skill for Claude Code, Codex from flurdy/agent-skills. It costs 41 tokens per session (2,092 once invoked), scanned C, original, MIT.

A bridge between Trello, a board-based task tracker, and Beads, a project-management workflow. It pulls selected Trello cards into Beads and sends completed Beads items back to Trello.

In plain words
What is it for?
Use it to set up the integration, pull cards from Trello lists, and synchronize closed Beads items with Trello.
Why use it?
It removes the need to copy triage, bug, and completed work between two separate task systems.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 C, and why

trello-beads scanned grade C with 2 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 yesterday.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/owning-store.sh, scripts/trello-api.sh, scripts/trello-pull.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

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

The scripts send the API key and token in Trello's documented OAuth `Authorization` header. The shared request helper feeds that header to curl through standard input so credentials do not appear in request URLs, process

Trello-Beads — Board Integration for Beads Workflow

Interact with Trello boards and integrate with Beads project management.

Prerequisites

  • Environment variables set (via direnv .env.local):
    • TRELLO_API_KEY — from https://trello.com/power-ups/admin
    • TRELLO_TOKEN — generated from the same page
    • TRELLO_BOARD_ID — your board ID
    • TRELLO_LIST_TRIAGE — column name for cards to pull into beads (default: "Triage")
    • TRELLO_LIST_BUGS — bug column name (default: "Bugs")
    • TRELLO_LIST_DONE — done column name (default: "Done")
  • Scripts symlinked into project scripts/ directory (see Setup below)
  • Run from inside the repository that holds the board configuration. Its own .beads store owns every bead the board produces: the scripts prove that store from the Git toplevel and run every bd call as bd -C <that repository>. Outside a repository, or in one without a store, they fail closed before any Trello request or bd call rather than letting bd walk up to a parent or workspace store.

Setup

When invoked as /trello-beads setup, or when setting up a new project:

Step 1: Symlink scripts

mkdir -p scripts
SKILLS_DIR="${SKILLS_DIR:-${CODEX_HOME:-$HOME/.codex}/skills}"
if [[ ! -d "$SKILLS_DIR" ]]; then
  SKILLS_DIR="${CLAUDE_HOME:-$HOME/.claude}/skills"
fi
ln -sf "$SKILLS_DIR/trello-beads/scripts/trello-api.sh" scripts/trello-api
ln -sf "$SKILLS_DIR/trello-beads/scripts/trello-pull.sh" scripts/trello-pull
ln -sf "$SKILLS_DIR/trello-beads/scripts/trello-sync.sh" scripts/trello-sync

Verify:

./scripts/trello-api help
./scripts/trello-pull help

Step 2: Create .env.local from template

Copy .env.local.dist if it exists, or create .env.local with:

TRELLO_API_KEY=<your-api-key>
TRELLO_TOKEN=<your-token>
TRELLO_BOARD_ID=<your-board-id>
TRELLO_LIST_TRIAGE=Triage
TRELLO_LIST_BUGS=Bugs
TRELLO_LIST_DONE=Done

Find your board ID with:

./scripts/trello-api boards

Step 3: Ensure .env.local is gitignored

Files

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
