Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: names the AskUserQuestion tool.

This is prolific-oss/cli's own configuration. It tells Claude Code how to work on cli itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything cli configures →

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

cli-command-create 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 2d 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.

CLI Command Creator

When to Use This Skill

Invoke this skill when the user:

  • Asks to "create a command", "add a command", or "implement a command" for the CLI
  • Mentions adding new CLI functionality (e.g., "create me a command that publishes collections")
  • Uses the slash command /cli-command-create

Create a new CLI command for the Prolific CLI from start to finish.

Arguments

Arguments may be provided via $ARGUMENTS or gathered interactively.

Expected arguments:

  • ticket - Jira ticket number (e.g., DCP-2154)
  • resource - Resource name (e.g., collection, study, workspace)
  • command - Command name (e.g., list, get, create, update)
  • command-type - Optional: LIST | VIEW | CREATE | UPDATE | ACTION (will infer if not provided)

If arguments are missing or $ARGUMENTS is empty, use the AskUserQuestion tool to gather them:

  1. First ask for the Jira ticket number (e.g., "DCP-2154")
  2. Then ask for the resource name (e.g., "collection", "study", "workspace")
  3. Then ask for the command name (e.g., "list", "get", "create", "publish")
  4. Finally ask for the command type with options: LIST, VIEW, CREATE, UPDATE, ACTION (or let Claude infer from the command name)

Phase 1: Gather Requirements

1.1 Understand the API Contract

Ask the user to provide ONE of:

  • Bruno file path - e.g., path/to/request.bru
  • Inline API contract - endpoint, request/response examples, error codes

Also ask if they have any acceptance criteria (optional):

  • Feature requirements or user stories
  • Expected behavior descriptions
  • Edge cases to handle

1.2 Determine Command Type

If not provided, infer from command name:

  • list → LIST (paginated results, multiple renderers)
  • get, view → VIEW (single resource, one renderer)
  • create → CREATE (accepts template file)
  • update → UPDATE (modifies existing resource)
  • Other → ACTION (state transitions, operations)

1.3 Identify Required Flags

Based on command type, confirm which flags are needed:

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.
