Settings file for Claude Code

Written for Claude Code: installed under .claude/.

This is coder/coder's own configuration. It tells Claude Code how to work on coder itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything coder configures →

One of 2 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 1 are separate, each on its own page.

About the project

Coder is a self-hosted platform for creating cloud development environments and running AI coding agents on an organization's own infrastructure. Development teams use Terraform-defined workspaces, secure connections, model governance, and centralized auditing to support developers and delegate coding work. The catalogue entries provide agents, skills, integrations, instructions, settings, hooks, and rules for working with Coder.

Security

Grade A, and why

coder 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 2mo 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.

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.
