turnstile-work

turnstile-work is a skill for Claude Code, Codex from febradc-github/turnstile. It costs 42 tokens per session (1,433 once invoked), scanned A, original, MIT.

A workflow for implementing one approved sprint ticket using TDD, or test-driven development: writing checks before or alongside the code, then using them to guide the change.

In plain words
What is it for?
Use it to carry out an in-progress sprint ticket, consult related notes and specifications, write code through the project’s coding agent, and verify the result.
Why use it?
It prevents work from starting without an active, approved item and keeps implementation aligned with the ticket’s specification and recorded decisions.

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-work 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 3d 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.

Work

Process

  1. Look up <id> (from $ARGUMENTS) in the current board -- turnstile/sprint.yml (a sprint or a mode: flow board), or (legacy) the root turnstile/sprint-<N>.yml with sprint.status: active. No active board, or id not on it: tell the user and suggest /turnstile:sprint-plan -- /turnstile:next in cadence: flow -- (or /turnstile:quick for small work).
  2. assignee: human: refuse and point the user at the item.
  3. status not todo or in_progress (never planned in, mid-review, or parked): refuse and redirect to the correct step -- for a parked item, /turnstile:pickup un-parks it with its resume context.
  4. Another item already in_progress: refuse; the user finishes it via /turnstile:review first.
  5. Search the vault for notes related to this ticket's topic. Surface anything relevant, including conflicts, before writing code. Pay particular attention to adr-* and AR-* notes touching this area: the implementation must not silently contradict a recorded decision.
  6. Read the ticket's spec -- turnstile/specs/SP-<n>.md (<n> from <id> = C-<n>), falling back to legacy names (turnstile/specs/<id>-*-spec.md, turnstile/specs/<id>.md). No spec file means a quick-lane item: its criteria live in the item note's "## Acceptance criteria" section. If the item has a parent, also read the parent chain's design docs (DS-<parent n>, or legacy names) -- the umbrella rationale often settles questions the leaf spec doesn't repeat.
  7. Set status: in_progress if it was todo -- before writing any code, so an interrupted session still leaves the board accurate.
  8. If any acceptance criterion is UI-facing, defer to frontend-design (if installed) for that portion.
  9. Ask the user:

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.
