devspace AGENTS.md

A set of project instructions for DevSpace, a local workspace layer that lets tools read files, edit code, run commands, manage Git worktrees, and coordinate limited helper agents.

In plain words
What is it for?
Use it when developing or maintaining DevSpace and need guidance on its product model, security boundaries, or the correct system layer to change.
Why use it?
It explains DevSpace’s boundaries and how its workspace, tools, instructions, and review checkpoints should work together.

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

devspace 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 yesterday.

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.

DevSpace

DevSpace is a local development execution layer for MCP hosts such as ChatGPT and Claude. It gives a remote host workspace-scoped tools for reading, editing, searching, running commands, managing Git worktrees, reviewing changes, and coordinating bounded subagents on the user's machine.

Pi's SDK currently provides mature local coding primitives. DevSpace wraps those primitives in a Streamable HTTP MCP server and adds the product-specific boundaries around them: approved roots, workspace state, instructions, process sessions, worktrees, artifacts, review checkpoints, widgets, and subagent execution.

DevSpace owns tooling mechanics. The model receives only meaningful and actionable choices. The user sees outcomes. Tool defination should not leak internal implementation or it shoudn't be giving unwanted options to model to choose from if tooling can handle this.

Product model

These ideas should stay true as the project evolves:

  1. The host is the orchestrator. DevSpace exposes clear capabilities and execution state. It should not hide the workflow inside an opaque, uninspectable agent loop.
  2. Everything happens in a workspace. A workspace represents one local project directory or worktree plus the instructions and state accumulated while operating in it.
  3. Local authority stays explicit. DevSpace runs with access to the user's machine. Roots, paths, commands, processes, credentials, and destructive operations must be treated as product boundaries.
  4. Subagents are bounded workers. A subagent should have an explicit task, profile, working context, lifecycle, and result that the host can inspect and coordinate.
  5. Adapters stay at the edges. Pi, MCP hosts, and model providers each have their own terminology and capabilities. Provider-specific behavior should not become the core domain model.
  6. Prefer composable primitives. Build a small set of reliable operations that can be combined into larger workflows instead of baking every workflow into the server.

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.
