Compaction Strategies
Implement hook-based history compaction in fast-agent (rolling window, context threshold truncation, tool-result clearing, summary prompt compaction). Use when adding or extending compaction hooks and wiring them into agent cards.
Lsp Setup
LSP-enable a Python, TypeScript, or Rust repository for fast-agent development. Use when creating or refreshing agent cards with LSP function tools, configuring ty, typescript-language-server, or rust-analyzer integration, or scoping repo-local code navigation safely.
Fast Agent Automation
Automate fast-agent runs from CLI, Docker, and Hugging Face Jobs. Use when users need repeatable non-interactive execution (`fast-agent go --message` / `--prompt-file`), deterministic artifact handling (`--results`), multi-model fan-out, containerization with uv, or scheduled/cloud execution with hf jobs and secrets management.
Agent Card Hooks
Guide for implementing fast-agent hooks and user-invoked command actions. Use when adding hook functions to agent cards or Python code for tasks like history compaction, saving sessions, modifying tool calls, managing agent lifecycle, or adding explicit slash-command add-ins with PluginCommandActionContext.
Gepa Fast Agent
Build, review, or refactor GEPA optimization loops that use fast-agent. Use when Codex needs to design GEPA evaluators, Actionable Side Information, Pareto/frontier metrics, FastAgentReflectionLM, FastAgentBatchEvaluator, BatchRunner, EvalRun/CandidateRun artifact layouts, Trackio monitoring, or refactor OpenClaw/Birch-style prompt, policy, skill, batch, or artifact-generation optimizers.
Birchline Html
Create polished standalone single-file HTML engineering artifacts in the Birchline design language. Use for session summaries, module/process explainers, implementation plans, design direction comparisons, PR/change writeups, findings-first code reviews, incident/status reports, slide decks, flow diagrams, and compact numeric/data briefs where the output should be a beautiful local HTML document…
Session Investigator
Investigate fast-agent session and history files to diagnose issues. Use when a session ended unexpectedly, when debugging tool loops, when correlating sub-agent traces with main sessions, or when analyzing conversation flow and timing. Covers session.json metadata, history JSON format, message structure, tool call/result correlation, and common failure patterns.
Hf Space Deployer
Deploy fast-agent MCP Servers to Hugging Face Spaces using Docker. Use when the user wants to deploy an "agent card" as an MCP Server. Includes templates and CLI commands for deploying agent cards with custom tools to HF Spaces.
