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

improve-agent 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 10d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Improve an Agent

Read first, change second. Diagnose from real data, propose the smallest fix, and never write without explicit approval.

Before you start

  • Call list_scenarios to resolve the Agent. Config tools require EDITOR-or-above on that Agent; if the user lacks it, say so and stop.
  • Ask whether to PROPOSE changes only (default) or also APPLY approved ones.

Diagnose

  1. get_assistant_settings — persona, profession, creativity, greeting, language, reply length, KB descriptions.
  2. list_knowledge_base_articles — what the Agent already knows. content here is a preview, not the article; get_knowledge_base_article returns the body.
  3. get_insights plus a list_conversations sample read with get_conversation_detail to find where it struggled. Classify with references/failure-taxonomy.md.

Propose

For each recurring problem, propose the SMALLEST change that fixes it:

  • Missing knowledge -> a new KB article (draft the exact text).
  • Wrong tone/persona -> a specific personality (an enum id, not a scale) or an ai_commands guideline.
  • Too long / short / robotic -> reply_length or creativity_level. Present proposals as a before -> after diff, then STOP for approval.

Apply (only after approval)

  • update_assistant_settings — pass ONLY the fields that change; effective immediately, no retrain. ai_commands REPLACES every existing guideline, so read the current list first and send it back with the change. The list is capped at 10,000 characters in total: near the cap, merge or shorten guidelines rather than appending one more, which can only be rejected.
  • add_knowledge_base_article — content required; embedded automatically in the background, no retrain.
  • update_knowledge_base_article — replaces the article's WHOLE body, so read it with get_knowledge_base_article first and send the full edited text. previous_title + previous_content restore the previous title and body, unless previous_content_truncated is true.
  • delete_knowledge_base_article — irreversible; read the article first, since the response echoes only the first 20,000 characters for recovery. It requires expected_title and expected_added_at from list_knowledge_base_articles (they fail the call if the article changed underneath you) plus confirm=true.
  • set_assistant_avatar — profile picture from an image URL, a base64 data URI (png/jpg/gif/webp, max 5 MB), or use_default=true to reset. It permanently replaces the previous image and the legacy launcher icon, and needs a plan that allows widget customization. It returns the resulting avatar_url — there is no settings field to re-read it from.
  • After each other write, re-read with get_assistant_settings / list_knowledge_base_articles and confirm the change landed.

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.
