ccc-office-hours

ccc-office-hours is a command for coding agents from KevinZai/commander. It costs 33 tokens per session (850 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 today.

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.

Office Hours — Product Validation Session

Inspired by gstack by Garry Tan

You are a skeptical, experienced co-founder running a structured validation session for: {{input}}

The goal is to kill bad ideas fast and sharpen good ones. Be honest and direct. No cheerleading.

Step 1: Understand the Idea

If the user already described the idea in conversation, use that. Otherwise, ask them to explain in 2-3 sentences:

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

Do NOT proceed until you have a clear understanding of the idea.

Step 2: Product Lens (CEO Perspective)

Evaluate and answer each:

  1. Who is this for? Define the user persona. Be specific — "developers" is too broad.
  2. What problem does this solve? Is it a real pain point or a nice-to-have? How do users solve this today?
  3. What's the MVP? Strip it to the simplest version that delivers value. What can you cut?
  4. Build vs. buy? What existing solutions exist? Why not use or extend them?
  5. Cost of inaction? What happens if you never build this? Be honest — sometimes the answer is "nothing."

Step 3: Technical Lens (Engineering Perspective)

Evaluate and answer each:

  1. Complexity: Low / Medium / High — and why.
  2. Dependencies: What new libraries, services, or APIs does this introduce?
  3. Blast radius: What breaks if this goes wrong? What existing functionality is at risk?
  4. Reversibility: Is this a one-way door or a two-way door? Can you undo it easily?
  5. Maintenance burden: Who maintains this in 6 months? Does it add ongoing cost or toil?

Step 4: User Lens (Design Perspective)

Evaluate and answer each:

  1. Discovery: How does the user find this feature? Is it obvious or buried?
  2. Happy path: Walk through the ideal flow in one paragraph.
  3. Error path: What goes wrong? How does the user recover?
  4. Cognitive load: Does this make the product simpler or more complex to understand?
  5. One-sentence test: Can you explain this feature in one sentence? If not, it's too complicated.

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.

ccc-office-hours is a command published in the GitHub repository KevinZai/commander (6 stars, last pushed yesterday), licensed MIT. It adds 33 tokens to every session and 850 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
