coder: Skill for Claude Code

.agents/skills/dogfood/SKILL.md

dogfood is a skill for Claude Code, Codex from coder/coder. It costs 53 tokens per session (1,975 once invoked), scanned A, original, AGPL-3.0.

A workflow for testing a pull request in a running Coder development instance. It checks the correct branch, starts the application, tests the changed behavior, and records findings, including visual evidence when needed.

In plain words
What is it for?
Use it to validate pull-request changes through the user interface, inspect the pull-request context, and report observed problems.
Why use it?
It helps confirm that a change works in the application instead of relying only on reading the code or running automated checks.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is coder/coder's own configuration. It tells Claude Code and Codex 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 →

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.

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

dogfood 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 1mo 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.
