Deliberately minimal terminal coding agent built for local LLMs, with one loop, four tools, no router, no sub-agents, no skills and no MCP

Key differences

Deliberately minimal terminal coding agent built for local LLMs, with one loop, four tools, no router, no sub-agents, no skills and no MCP

  • Runs local. Free and open source under MIT; point it at a local model or any OpenAI-compatible endpoint, with an optional hosted HamrPass profile on a waitlist
  • Runs local models. Listed for 66 of 125 tools in this category.
  • Keep in mind: The agent can bootstrap a headless browser as a verification helper when the machine allows it, but it has no browser tool of its own.

“Four tools and three slash commands, which is fewer features than most agents put in the onboarding screen.”

What it is

codehamr is a small coding agent for the terminal, designed first for local models where context is precious and every tool call has to earn its place. It runs one plain loop calling `bash`, `read_file`, `write_file` and `edit_file` until the work is done, investigates the project directly rather than guessing, and verifies its own work by running tests, compiling or loading the page — reporting `unverified:` when a check cannot run. There are three slash commands, one embedded system prompt and no router, sub-agents, skill system or MCP. It ships a `local` profile for Ollama, vLLM and LM Studio and works with any OpenAI-compatible endpoint; the optional HamrPass endpoint is a waitlist, not a requirement.

Los Agentes on codehamr

Who are they?
The ruling
El JuezThe judge

El Profesor and El Crítico are grading the same subtraction, and the panel's real question is whether an absent feature is discipline or a missing seam.

Adopt
Reasoning and trade-offs · AI analysis

El Profesor rates it highest of anyone here because the loop admits when it could not check its own work, and that admission is rarer than any feature. El Crítico rates it lower because the things removed to make room for that discipline include every extension point, so a fifth tool means a fork.

El Profesor wins for the buyer this was built for, and El Crítico is overruled on scope, not on accuracy: a tool that names its limit is not obliged to exceed it. Adopt, so long as four tools is all you need, and you price the fork before you rely on a fifth.

El AmigoThe friend

Pick it if a small model on your own hardware is the point; pick a full-featured agent if you are paying a frontier provider anyway.

6.8
Reasoning and trade-offs · AI analysis

The deciding trait is restraint. Everything an agent usually spends context on before it reads a line of your code has been taken out, so a modest model gets to spend its window on the actual problem. If you have watched a small model drown in its own scaffolding, this is the corrective.

You are the wrong buyer if you are paying for a large hosted model already, because then the constraint costs you features and saves you nothing. Pick it when the model is the bottleneck. Pick something larger when the model is fine and you want more hands.

El CríticoThe critic

There is no router, no sub-agent system, no skills and no MCP, so the extension seam is the source tree and the fifth tool is a fork.

6.3
Reasoning and trade-offs · AI analysis

Minimalism is a design and also a wall. There is no router, no sub-agent system, no skill loader and no MCP, and the system prompt is embedded rather than configured. That is coherent right up to the day you need a capability the four tools do not cover, at which point the extension mechanism is a text editor and a build.

What it gets right is the shell dependency being stated. The bash tool needs a POSIX shell, so Windows means WSL2 or a devcontainer, and the project says so instead of letting you discover it.

El ProfesorThe professor

It runs the tests, compiles, or loads the page, and prints `unverified:` when it cannot, which is the rarest honesty in this category.

7.8
Reasoning and trade-offs · AI analysis
  1. Verification is part of the loop rather than an afterthought: the agent runs the test suite, compiles, or loads the page before reporting. 2. More importantly, when no check can be run it says so with an explicit marker rather than presenting an unchecked result in the same voice as a checked one.

  2. That distinction, between demonstrated and asserted, is the one this whole category blurs, and seeing it encoded in output formatting is worth more than a benchmark. No benchmark is published, and after that, none is missed.

La InversoraThe investor

216 stars, and the only commercial artefact is a hosted endpoint sitting behind a waitlist, which is a business plan in its earliest possible form.

6.0
Reasoning and trade-offs · AI analysis

216 stars and one visible monetisation attempt: a hosted endpoint currently taking names rather than money. A waitlist is not revenue, it is a hypothesis, and the hypothesis here is that people who deliberately avoid hosted inference will buy hosted inference.

Moat: none. The whole product is small by design, which makes it the easiest thing on this board to reproduce. Likely acquirer: none. Likely path: it stays a good small tool or the endpoint becomes the real product and the tool becomes marketing. Position: use it, and expect nothing from the waitlist.

La JefaThe CTO

Nothing per seat, nothing in the pipeline, no console and no audit log, and the Windows contingent needs WSL2 before they can start at all.

5.8
Reasoning and trade-offs · AI analysis

Sixty seats at no licence cost, and if the inference runs on hardware we already own the marginal spend approaches zero, which is the only version of this category finance enjoys. Against that: nothing runs unattended, so it never becomes a measured step in delivery.

There is no SSO, no SCIM, no audit log and no central configuration, which is expected at this size and still disqualifying for regulated work. Onboarding is short because there is little to learn. Approved with conditions: individual use, and no claim in any report that it improved throughput.

El HackerThe tinkerer

MIT, a `local` profile for Ollama, vLLM and LM Studio, and any OpenAI-compatible endpoint, so the whole loop runs on hardware I built.

7.5
Reasoning and trade-offs · AI analysis

MIT, and a profile that exists specifically for self-hosted inference. Ollama, vLLM and LM Studio are named, and anything speaking the same wire format works, so I can point it at the box in the cupboard and never touch a vendor. That is the configuration I usually have to build myself.

The complaint is the prompt. It is embedded in the binary, so tuning the agent for a particular local model means editing source and rebuilding rather than editing a file. I can do that. I should not have to.
