turnstile-board is a skill for Claude Code, Codex from febradc-github/turnstile. It costs 15 tokens per session (488 once invoked), scanned A, original, MIT.

A read-only view of a project board showing the backlog and the currently active sprint. A backlog is the list of planned work, while a sprint is a focused set of work in progress.

In plain words
What is it for?
Use it to inspect epics, stories, tasks, sprint items, completion progress, and work added during a sprint.
Why use it?
It gives a structured snapshot of work, hierarchy, status, points, and progress without changing the board.

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

turnstile-board 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

Board

Purpose

Renders the full board -- backlog plus active sprint -- as a readable snapshot, with no side effects.

Process

  1. Read turnstile/backlog.yml (if it exists). Render its items as a table: id, title, type (epic/story/task; blank means story), status (idea/ready/done/dropped), points. Group hierarchically: each epic first, its children indented beneath it (and their tasks beneath them), then flat items. For every container, append child progress to its row: <done children>/<total children> done, counting children across the backlog, sprint.yml, and sprints/*.yml. Render dropped items last, marked as cancelled.
  2. Read the current board -- turnstile/sprint.yml (a sprint or a mode: flow board), or (legacy boards) the root turnstile/sprint-*.yml with sprint.status: active. Render its goal (sprints only) and items as a table: id, title, parent (when set), status (todo/in_progress/review/done/dropped), points, carryovers, and a + marker on items with added_mid_sprint: true. Then report scope honestly: total points, points done, and -- if any item has added_mid_sprint: true -- "N of M points were added mid-sprint" so quiet scope growth stays visible.
  3. If neither file exists yet, tell the user the board is empty and suggest /turnstile:refine <idea> to start.

Inputs

turnstile/backlog.yml, turnstile/sprint.yml, turnstile/sprints/*.yml.

Outputs

None -- read-only.

Error handling

  • Malformed YAML in a board file: surface the parse error and ask the user to fix it by hand -- never guess or auto-repair.
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.
