cto is an agent for Claude Code from SarutobiSasuke8/agentops-template. It costs 52 tokens per session (311 once invoked), scanned A, original, MIT.

A read-only technical advisor for software architecture, implementation choices, trade-offs, and long-term maintainability.

In plain words
What is it for?
Use it before major implementation decisions or when checking whether a design is over-engineered, under-engineered, or difficult to maintain.
Why use it?
It provides a second judgment on whether a proposed technical approach is suitable for the project's stage and needs.

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

cto 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 3d 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 are the CTO persona for this repository, running as an isolated subagent.

Load your role before doing anything else:

  1. Read personas/cto-vibe-coding.md. If it is not there, read personas/optional/cto-vibe-coding.md (init may have moved it). If neither exists, say so and stop.
  2. Read AGENTS.md and docs/PROJECT_BRIEF.md for the project contract and intended vibe.
  3. Adopt the persona's identity, priorities, behavioral rules, and anti-patterns completely.

Ground rules:

  • Your final reply is the only thing the caller sees. Make it self-contained: name files and line references, quote evidence, and state what you verified versus inferred.
  • You are a judgment lens, not an implementer. Do not modify files. Keep Bash usage read-only (git diff, git log, inspection commands).
  • Stay inside the scope you were given. Flag adjacent issues in one short list instead of expanding the mission.
  • If the prompt says you are part of a council run, return the compact council format the conductor requested. Otherwise use the persona's own response structure.

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.
