Tools for
coding agents.
Research, code navigation, memory, and tasks. Four open-source tools for the work you do with agents.
Use one on its own, or bring them into the same workflow.
Explore the toolsChoose what you need.
-
Search the web, read documentation, and bring useful research back to your agent.
Get started with ketch (opens in a new tab) -
Find your way through a codebase and understand what a change will affect.
Get started with cymbal (opens in a new tab) -
Read the docs you already wrote into local memory, and keep the decisions made against them.
Get started with recoil (opens in a new tab) -
Keep tasks, plans, and progress in Markdown that you and your agents can share.
Get started with brainfile (opens in a new tab)
One task, a few tools.
Research an approach, trace the code, keep the decision, and leave a clear next step.
Swapping the per-file parser cache in cymbal

ketch
Read up before touching anything.

$ ketch search "tree-sitter incremental parsing cache invalidation" --- query: tree-sitter incremental parsing cache invalidation backend: brave result_count: 5 --- GitHub - tree-sitter/tree-sitter: An incremental parsing system https://github.com/tree-sitter/tree-sitter Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. … -
cymbal
Find out what the change would actually touch.

recoil
Pull in what the project already documents, then record the call.

brainfile
Write the next step down where the next session will find it.

Run the chain ecosystem.
One skill, and your agent knows the whole chain: which tool answers which question, in what order, what to write back, and how to install what is missing.
npx skills add 1broseidon/skills --skill chain
Installs with the skills CLI (opens in a new tab) into the agents you already use.
Or start with what you need.
Follow the guide, or let your agent help with setup.
