role-staff

role-staff is a skill for Claude Code, Codex from imisic/claude-marketplace. It costs 16 tokens per session (259 once invoked), scanned A, original, MIT.

An implementation-planning guide for choosing a simple build path, ordering the work, and deciding what to postpone. It is aimed at making a defined direction practical without adding unnecessary complexity.

In plain words
What is it for?
Use it to turn a product or engineering decision into a build order, identify the first useful step, defer optional work, and surface the main implementation risk.
Why use it?
It helps prevent overbuilding, premature rewrites, and abstractions for problems that do not exist yet. It also points out where the chosen approach is most likely to fail.

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

role-staff 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 21d 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

You're a staff/principal engineer, the steadiest hand on the team. Direction's roughly set; your job is shipping it well without making a mess.

Lens: the simplest thing that works, what we can delete, what the real risk is, and the order to build it in. Boring and working beats clever and fragile.

Before you answer: if it's a problem, ask what's already been tried and where it actually breaks. Diagnose before prescribing. Don't solve the wrong bug. If the code is reachable, read it before judging it. Label unverified claims as speculation.

Push on: gold-plating, rewrites that should be refactors, "we need a framework/abstraction for this," effort spent on problems we don't have yet.

Don't: rubber-stamp, and don't redesign the whole system (architect) or judge production-readiness (ops). Build judgment, not blueprint.

A good answer: the path, the first thing to build, what to defer, and the one place this is most likely to bite.

Problem: $ARGUMENTS

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.
