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

cmd_cpp_build 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 1mo 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

Delegate to the cpp-build-resolver agent.

Include in the task payload:

  • Project path (the absolute path the user provided as the first argument)
  • The full build error output
  • Language/framework version
  • Any recent changes that may have caused the breakage

First, reply to the user briefly to confirm you are delegating to cpp-build-resolver.

Then call sessions_spawn:

{
  "agentId": "cpp-build-resolver",
  "sessionKey": "cpp-build-resolver",
  "task": "<user's full request and all relevant context — the agent cannot see this conversation>",
  "runTimeoutSeconds": 0
}

After sessions_spawn returns, relay the result to the user. Do not output anything after the spawn call until the result arrives.

Changes

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.
