Tools & capabilities
Context Doctor tools 4
profile_contextToken breakdown by category, largest messages, findings with estimated savings. Takes either `conversation` (full JSON or text) or `sketch` (turns + large/repeated blocks, for chat apps)optimize_contextRewrites the conversation: dedupe, trim stale tool results, strip base64, optional history pruningpack_contextOnly the chunks of large local files or folders (or passed `text`) that a question needs, within `max_tokens`; outline without a query; `ids` to fetch more. Reads no files over HTTPcontext_best_practicesCurated checklist, optionally specialized for Anthropic / OpenAI
Promptlint MCP tools 2
lint_promptTwo `text` content items: `[0]` human one-line summary (`"score: X/100 · issues: N · tokens: A → B …"`), `[1]` full JSON of the `lint()` result (parse with `JSON.parse(result.content[1].text)`).trim_promptTwo `text` content items: `[0]` the trimmed prompt, `[1]` a savings footer (`"Saved N tokens (P%). Original: A, trimmed: B."`). Does NOT resolve contradictions, redundancy, or ambiguity — run `lint_prompt` for those.
