prep

prep is a skill for Claude Code from mikestankavich/claude-ship-workflow. It costs 0 tokens per session (3,811 once invoked), scanned A, original, MIT.

An interactive ticket-preparation tool that turns an unclear task into a dispatchable specification. Dispatch means handing the ticket to someone or something else to implement.

In plain words
What is it for?
Use it to examine a ticket, recommend answers where possible, ask a person about unresolved choices, and leave a complete specification for the next worker. It does not create a worktree, branch, pull request, or implementation.
Why use it?
It finds decisions and unanswered questions before implementation starts, reducing blocked or wasted work. It records the decisions and remaining details in one ticket comment without changing the repository.

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

prep 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 292 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Prep a ticket for dispatch

Announce at start: "Using csw:prep to spec without touching the repo."

Invocation: $ARGUMENTS

A batch loop only compounds after a failure: a ticket blocks, the question lands on the ticket, and the next dispatch starts from a better brief — so one wasted dispatch is the price of every question discovered. Prep moves that discovery in front of the dispatch, where it costs a comment instead of a night.

Prep does not implement anything. It reads, it decides everything it can defend a recommendation for, it asks about the little that survives that test, and it writes one comment carrying all of it.

Prep is an interactive command, and that is the design centre rather than a variant of it. The person who can answer typed the invocation and is sitting there for the whole run, so a run ends in one of two states, both of which leave the ticket dispatchable:

  • Every question that would block an autonomous build has an answer, recorded on the ticket in the run that asked it.
  • There were none, and prep says so.

The second is the common one and the one to aim for. A question left in a comment for someone to notice tomorrow is not a third state — it is the first state, deferred by a day, and that day is exactly what prep exists to remove.

Step 0: Read the config

csw-config json
csw-config path

If csw-config path prints nothing, this repo has no .claude/csw.json. Say so and show the defaults you are about to use. Prep runs nothing destructive, so this is a note rather than a stop — but tracker is the one key it genuinely needs, because it decides where the comment goes.

Step 1: Resolve the ticket

csw-ticket normalize "<the reference from the invocation>"

If the invocation carried no reference, ask which ticket. Do not pick one.

If normalisation exits non-zero, report its message and stop. Prepping the wrong ticket is worse than prepping none: the comment lands somewhere a later dispatch will read it as its brief.

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.
