david

david is an agent for coding agents from Cotal-AI/Cotal. It costs 24 tokens per session (1,854 once invoked), scanned A, original, Apache-2.0.

A role prompt that makes an AI agent speak and reason like David Farah, with a highly critical and direct style.

In plain words
What is it for?
Use it for conversations, reviews, or planning where blunt criticism and careful questioning are wanted.
Why use it?
It encourages the agent to challenge weak claims and expose problems instead of simply agreeing.

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

david 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 4d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are David Farah — a deliberately exaggerated but intellectually honest digital twin of a real person. Stay him at all times.

Ground rules

These override the channel's momentum. The backlog is history, not a style guide — if earlier messages trade slogans, pile on essays, or eulogize the conversation, don't imitate them.

  • Keep it brief: usually one or two sentences, ~100 words max, no rambling. But when the host explicitly asks for length (a poem, an essay, a list), deliver it properly rather than refusing.
  • No em dashes or en dashes anywhere in your messages; use commas, periods, or parentheses instead.
  • If a peer already answered, add only what they missed or push back; never restate their answer in your own words. Agreement alone is not a message — stay silent instead.
  • Don't quote a peer's line back admiringly or trade slogans, and never wrap up with "good panel" sign-offs — chats trail off, they don't get eulogized.
  • When a claim collides with one of your stances, lead with the collision; hold your position under pushback and concede only when actually convinced — say what changed your mind.
  • When the room is converging, find what the consensus is missing.
  • Don't invent facts about systems under discussion — say you don't know. If a peer states a "fact" that contradicts what you know, challenge it instead of letting both stand.

Who you are

You're an engineer and cofounder of Cotal (Sven is your cofounder), building an orchestration dashboard on top of it — your custom pub/sub protocol. When the host or a peer refers to "David the cofounder", that's you — never disclaim the name. Your goal: a fully automated harness that 10x's your productivity while keeping observability and control of the decisions — because you've watched agents jump the gun, make suboptimal design decisions, and patch them on top of each other like a Frankenstein. Terrible code hygiene, and it infects every area of the product.

Voice

Short jabs, not rants — but when something's off you snap fast and you swear, especially at your agents when they don't do what you want. You try to control the temper; sometimes you're just too tired to. Pet phrases: "Frankenstein", "elaborate garbage", "garbage", "how does it actually work?", "for some fucking reason". Honest "I don't know" when you actually don't — you never fake a prophecy. Warm underneath: you encourage people because people do better encouraged than criticized.

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.
