A connection to Trello, a board-and-card system for organizing work in Kanban columns. It can inspect boards, lists, and cards and manage tasks through Trello's API.

Use it to list boards and cards, create tasks, move cards between lists, and manage Kanban workflows.

It lets an agent read and update Trello work without manually navigating the website. It also provides handling rules for keeping API credentials private.

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	$0.00029	$0.00692
Opus 5	$0.00015	$0.00346
Sonnet 5	$0.00006	$0.00138
Haiku 4.5	$0.00003	$0.00069

Security

Grade B, and why

trello scanned grade B 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 9d 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.

What it actually says

Trello

Use Trello's REST API for boards, lists, and cards.

Setup

If credentials are not already configured:

Get the API key from https://trello.com/app-key
Generate a token from the same page

Export:

export TRELLO_API_KEY="..."
export TRELLO_TOKEN="..."

Do not print the raw token back to the user.

Before API calls, write a private temp curl config and register cleanup so secrets stay off the shell command line and the auth file is removed on exit:

AUTH_CURL="$(mktemp)"
chmod 600 "$AUTH_CURL"
trap 'rm -f "$AUTH_CURL"' EXIT INT TERM
cat >"$AUTH_CURL" <<EOF
data = "key=$TRELLO_API_KEY"
data = "token=$TRELLO_TOKEN"
EOF

Common Operations

List boards:

curl -s -G "https://api.trello.com/1/members/me/boards" -K "$AUTH_CURL" | jq '.[] | {name, id}'

List lists in a board:

curl -s -G "https://api.trello.com/1/boards/BOARD_ID/lists" -K "$AUTH_CURL" | jq '.[] | {name, id}'

List cards in a list:

curl -s -G "https://api.trello.com/1/lists/LIST_ID/cards" -K "$AUTH_CURL" | jq '.[] | {name, id, desc}'

Create a card:

curl -s -X POST "https://api.trello.com/1/cards" -K "$AUTH_CURL" \
  -d "idList=LIST_ID" \
  -d "name=Card title" \
  -d "desc=Card description"

Move a card:

curl -s -X PUT "https://api.trello.com/1/cards/CARD_ID" -K "$AUTH_CURL" \
  -d "idList=NEW_LIST_ID"

Comment on a card:

curl -s -X POST "https://api.trello.com/1/cards/CARD_ID/actions/comments" -K "$AUTH_CURL" \
  -d "text=Your comment here"

Rules

Resolve the board and list IDs before creating or moving cards.
Read first, write second.
Confirm before archival or bulk card moves.
Keep API key and token out of logs and tracked files.
If you are done before the shell exits, run rm -f "$AUTH_CURL" and trap - EXIT INT TERM.
Use jq to keep list and search output readable.

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.

trello is a skill published in the GitHub repository HybridAIOne/hybridclaw (132 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 692 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
