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

gollm AGENTS.md 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 2mo 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.

Build & Test Commands

Git Workflow

  • Rebase before merging: Always rebase feature branches onto main before merging to keep a clean, linear history. Use git rebase main or squash commits with git rebase -i to consolidate related changes.
  • Squash feedback fixes: When addressing PR feedback, consider squashing fix commits into the original feature commits before merging.
  • Delete merged branches: Clean up feature branches after merging.

Code Style

  • Follow Go conventions and existing patterns in the codebase
  • Use interfaces for extensibility (e.g., MemoryCapable over concrete types)
  • Write comprehensive tests, skip gracefully when providers unavailable
  • Deep copy data structures to prevent shared state issues

Testing Notes

  • Tests using lmstudio provider will skip if LM Studio is not running
  • Tests requiring API keys (Anthropic, OpenAI) will skip if keys are not set
  • Use createTestLLM helper pattern to skip tests gracefully
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.
