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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00136 | $0.04507 |
| Opus 5 | $0.00068 | $0.02253 |
| Sonnet 5 | $0.00027 | $0.00901 |
| Haiku 4.5 | $0.00014 | $0.00451 |
Grade A, and why
create-cofounder-prd 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 9d 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 — 288 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Autonomous Co-founder Projects PRD Generator
Generate a personalized Product Requirements Document for building an autonomous "co-founder" projects system: a layer that becomes the orchestrator of the larger, multi-session tasks you hand it. You drop a spec; it breaks the work into workflows, dispatches and monitors them in isolation, and steers toward done, with a human steering through chat and markdown edits.
The PRD works two ways, set by the Build mode answer in the template:
- Extend an existing second brain / agent - reuse its loop, memory, chat, and utilities; the phases say "add a pass" and "reuse X" (a lighter build).
- Standalone from scratch - no existing agent; the phases BUILD the minimal pieces (a small scheduler, a state folder, a notify path, the few utilities) so it stands alone.
The core is identical in both modes. It adapts to the user's stack through three adapter choices, so the same core fits any environment:
- Scheduler / trigger - reuse an existing proactive loop (a heartbeat), run a standalone cron, or (if they have neither) the PRD includes a phase to build a minimal one.
- Build engine - Archon, a Claude Code
/loopsession, CI (GitHub Actions), or a custom runner. The orchestrator only needs dispatch + poll + completion-env. - Chat platform - Slack, Discord, Teams, email, a webhook, or none (markdown-only).
A blank template is bundled at ${CLAUDE_SKILL_DIR}/my-cofounder-requirements.md. A worked
example (Cole's real Second-Brain-plus-Archon-plus-Slack setup) is bundled at
${CLAUDE_SKILL_DIR}/example-my-cofounder-requirements.md.
Parameters
$0(required) - Path to the filled-out requirements file (e.g.,./my-cofounder-requirements.md)$1(optional) - Output path for the PRD. Defaults to.agents/plans/cofounder-projects-prd.md
Workflow
- Read the requirements - Read the file at
$0. If no argument was provided, ask for the path. If they have not filled one out, point them at the blank template at${CLAUDE_SKILL_DIR}/my-cofounder-requirements.mdand the worked example.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

create-cofounder-prd is a skill published in the GitHub repository TheSmokeDev/taskchad-os (23 stars, last pushed 2d ago), licensed MIT. It adds 136 tokens to every session and 4,507 once invoked, about $0.0007 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 2026-08-30.
