ccc-office-hours

ccc-office-hours is a command for Claude Code from KevinZai/commander. It costs 50 tokens per session (983 once invoked), scanned A, original, MIT.

A structured product-validation conversation that examines an idea from business and engineering perspectives before code is written.

In plain words
What is it for?
Use it to decide whether to build, simplify, research further, or abandon a product idea, and to define a smaller first version.
Why use it?
It helps expose unclear users, weak problems, unnecessary scope, and unsuitable build-versus-buy choices before they consume development time.

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

ccc-office-hours 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 8d 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.

/ccc-office-hours — validate before you build

CC Commander · /ccc-office-hours · one honest verdict on an idea, and a planning brief when it is worth building.

Idea: $ARGUMENTS

Run a skeptical validation session. The aim is to kill weak ideas fast and sharpen strong ones. Be direct, give reasons, and do not cheerlead.

Step 1: Understand the idea

Use the idea from $ARGUMENTS or the conversation. If it is missing or vague, ask the user for two or three sentences covering:

  • What are you building?
  • Who is it for?
  • Why now?

Do not continue until the idea is clear.

Step 2: Product lens

  1. Who is this for? Name a specific persona; "developers" is too broad.
  2. What problem does it solve? Real pain or nice-to-have? How do users solve it today?
  3. What is the MVP? The simplest version that delivers value, and what can be cut.
  4. Build or buy? Which existing solutions exist, and why not use or extend them?
  5. Cost of inaction? What happens if this is never built? Sometimes the answer is nothing.

Step 3: Technical lens

  1. Complexity: low, medium or high, and why.
  2. Dependencies: new libraries, services or APIs it introduces.
  3. Blast radius: what breaks if it goes wrong, and which existing functionality is at risk.
  4. Reversibility: one-way door or two-way door; how hard is it to undo?
  5. Maintenance burden: who maintains it in six months, and what ongoing cost or toil it adds.

Where the idea touches an existing codebase, check these answers against the code (Grep, Read) instead of guessing, and cite the files.

Step 4: User lens

  1. Discovery: how does the user find it; obvious or buried?
  2. Happy path: the ideal flow in one paragraph.
  3. Error path: what goes wrong and how the user recovers.
  4. Cognitive load: does it make the product simpler or more complex?
  5. One-sentence test: can the feature be explained in one sentence? If not, it is too complicated.

Step 5: Verdict

Deliver exactly one:

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.
