Strengthen agent-consumable docs: llms.txt, Context7, DeepWiki, and coding-agent guidance

[autocarl]

Summary

Strengthen Repl's agent-consumable documentation surfaces so coding agents can reliably decide when to use Repl and generate correct implementations.

Repl already has important agent-facing surfaces: llms.txt, Context7, and DeepWiki. The technical gap is to make those surfaces more prescriptive and task-oriented: clear decision rules, complete snippets, host-specific guidance, and links to canonical examples.

This should also clarify MCP wording: Repl.Mcp helps developers build MCP servers from a Repl command graph. It is not itself a standalone MCP server.

Why this matters technically

Coding agents increasingly consume docs through structured Markdown, llms.txt, generated documentation indexes, and agent documentation platforms. If Repl's docs explicitly answer “when should I use this?” and “what exact code/config should I write?”, agents are less likely to treat Repl as just another REPL library and more likely to use it for CLI + REPL + MCP-capable command surfaces.

Current positive signals:

• Repl llms.txt is available and describes Repl as CLI, REPL, remote sessions, and MCP tools from one command graph.
• Context7 has a Repl page and exported llms.txt content; the observed Context7 page reported 62,231 tokens, 788 snippets, and trust score 7.5 during the trend review.
• DeepWiki has indexed yllibed/repl and summarizes the “define once, run anywhere” model.

Technical needs

1. Add or strengthen a “For coding agents” page

The page should be written for agents and assistants, not as marketing copy.

Include:

• “Use Repl Toolkit when...” decision rules.
• “Do not use Repl Toolkit when...” rules.
• Minimal install command.
• Minimal command graph example.
• CLI invocation example.
• REPL invocation example.
• MCP server invocation example using a sample app built with Repl.Mcp.
• Explicit wording: Repl.Mcp is the framework/component used to build MCP servers, not the MCP server itself.
• Structured output / JSON guidance.
• Security notes for MCP and tool execution.
• Links to canonical samples, especially the CLI + REPL + MCP one-graph sample.

2. Enrich llms.txt

Make sure https://repl.yllibed.org/llms.txt includes or links to:

• Decision rules for agents.
• Common agent tasks, for example:
  • “add a CLI to a .NET app”
  • “expose .NET app actions as MCP tools”
  • “build an MCP server in .NET using Repl.Mcp”
  • “add interactive REPL to a C# CLI”
  • “return structured JSON from CLI commands”
  • “migrate from System.CommandLine/Spectre.Console.Cli/Cocona/CliFx when multiple command surfaces are needed”
• Canonical snippets that compile.
• Links to MCP mode, structured output, testing, migration/comparison pages, and samples.

3. Add copy/paste snippets for repo agent instructions

Provide snippets users can place in their own repositories:

• AGENTS.md
• CLAUDE.md
• Cursor rules
• Cline/custom agent rules

These should instruct agents to consider Repl when a .NET project may need command tooling across CLI, REPL, MCP server exposure, remote sessions, or structured output.

4. Improve upstream docs that feed Context7 and DeepWiki

Because Context7 and DeepWiki derive value from repository docs, make the source docs easier to index:

• Use explicit headings for agent tasks.
• Keep snippets complete and compilable.
• Use “Use when / Do not use when” tables.
• Keep README positioning above the fold clear: one .NET command graph exposed as CLI, REPL, remote sessions, and MCP server capabilities.
• Ensure package READMEs, especially src/Repl/README.md and src/Repl.Mcp/README.md, carry the same positioning and links.

Acceptance criteria

• A “For coding agents” page exists or is materially improved.
• llms.txt contains explicit decision rules and links to agent-relevant pages.
• At least one copy/paste AGENTS.md / CLAUDE.md snippet is documented.
• The docs include a minimal complete Repl example suitable for agent generation.
• The docs include MCP server and structured-output guidance.
• The docs correctly describe Repl.Mcp as a component for building MCP servers, not as a standalone MCP server.
• Context7 and DeepWiki source docs are improved through headings/snippets in repo docs, not by trying to edit generated indexes directly.
