dshline AGENTS.md

Repository instructions for dshline, a terminal interface for DeepSeek Harness that runs inside the agent process. They describe the project structure, commands, and rules for changing the renderer or input handling.

In plain words
What is it for?
Use them when working on dshline’s terminal rendering, keyboard input, text escaping, session loop, or launcher packages.
Why use it?
They help developers avoid breaking conventions or missing important steps, such as building before manually testing. They also explain which package owns each part of the tool.

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

dshline 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 3d 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.

The opening of the file, as written. The whole thing — 243 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Instructions for an agent — or a person — working on this repository. If you want to use the interface, start at README.md. If you want to send a change, read CONTRIBUTING.md as well.

Read docs/design.md before changing anything about drawing, keyboard decoding, or text escaping. This file is the short version: the rules, the commands, and the mistakes that are easy to make.

What this project is

A terminal interface for DeepSeek Harness. It runs as a plugin inside the agent's own process, rather than as a client connecting over a network. There are two packages:

packages/renderer      @dshline/renderer   widths, keys, input line, boxes, screen — knows nothing about agents
packages/dshline       @dshline/dshline    the plugin: session loop, transcript, harness integration, view registry
packages/dshline/bin   dshline             a launcher wrapper, and deliberately nothing more

bin/dshline.mjs exists so that using this does not require remembering two things (dsh, --profile dshline). It finds the harness launcher, adds the profile and the working folder, and hands over the terminal with stdio: 'inherit'. It must never grow session logic: one implementation of the frontend is the point, and a wrapper that started doing its own work would be a second one.

That split is not just tidiness. The renderer must never import from the harness, and must never gain a dependency or a peer dependency. Having no dependencies is what lets this plugin add nothing to a user's setup, and it is why every rule below about widths, cutting, and escaping can be tested without a terminal and without a model.

Commands

pnpm install
pnpm build       # tsc -b for both packages
pnpm test        # the full suite, no terminal and no model required
pnpm typecheck   # tsc -b, same project graph
pnpm security    # the dependency and workflow checks CI runs

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.
