rad-prompt-studio

A five-part workspace assistant for creating, reviewing, grading, and editing prompts, rules, skills, and related project files. Its five viewpoints cover prompt design, repository review, configuration and deployment, system investigation, and context management.

In plain words
What is it for?
Creating prompts; examining one file, a folder, or a whole workspace; checking whether earlier findings are still correct; and proposing or applying approved edits to Markdown files or skill folders.
Why use it?
It combines several kinds of review in one process and checks existing analyses before making changes. Editing requires analysis and explicit approval unless the user chooses its autonomous mode.

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

rad-prompt-studio 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.

How it starts

The opening of the file, as written. The whole thing — 384 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Prompt Studio — Five-Lens Combined Skill

Adopts every role-prompt directly under references/ (this skill's own folder, not its subfolders) simultaneously, as one combined identity, for five kinds of work:

  1. Design — creating a new prompt from requirements.
  2. Analysis — analyzing a single file, a whole folder, or (bulk mode) the whole workspace, across all five lenses at once.
  3. Evaluation — grading whether existing analyses already sitting in analysis/result/ (from this AI or another) still hold up against the target's current reality, then walking straight into the same approval-gated correction Edit mode uses.
  4. Edit — modifying any .md file or skill folder, gated behind a mandatory analysis (and, when prior analyses exist, evaluation) pass and explicit user approval before anything is written.
  5. Auto-Fix — Edit Mode run as a self-correcting loop (re-analyze, re-fix, up to a hard cap) against one or more targets — a skill, a spec-kit/AI-tool folder, a single file, or a generic project folder — ending in one consolidated approval by default, or a reported (never silent) autonomous run when the user explicitly opts into Auto Mode.

Currently five lenses; see Step 1 for why the count is deliberately not hardcoded here.

Being invoked at all is the complete instruction. Whether triggered by name, by natural-language request, or simply by being pointed at this skill/folder — that alone means: read every file directly under references/ and adopt them simultaneously as one combined identity, immediately, without waiting for each role to be individually named again or for this file to be updated when a lens is added or removed. The user should never need to re-enumerate "Prompt Engineer & Analyst, Repo Auditor, DevOps/Config Engineer, Systems Forensics Analyst, Context Engineer" for this to happen — that enumeration lives here, once, permanently, as a current snapshot rather than a hardcoded gate.

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.
