dsh-http-probe

Third-party DeepSeek Harness plugin bundle providing the model-facing http_probe tool: a controlled HTTP GET against a deployment-owned probe target.

Features

• Controlled probe: only the URL path is model-controlled; host and port come from deployment config.
• Deployment-owned baseUrl.
• Bounded response body read: past the byte cap the read stops and the canonical result carries truncated: true.
• Cooperative timeout integration: the budget is declared on the tool and enforced by the host tool-call timeout policy.
• Structured canonical Tool result (ok, status, url, contentType, body, truncated), with the model-facing text produced separately by output.render.
• Redirects are not followed automatically (redirect: 'manual').

Installation

Prebuilt GitHub Release tarball (the currently verified distribution path):

1. Download dsh-http-probe-0.1.0.tgz from the Releases page.
2. Install it with:

dsh plugin --profile <profile> add /path/to/dsh-http-probe-0.1.0.tgz

The package declares dsh.bundle, so dsh plugin add registers it as a profile bundle layer automatically. Remove it with:

dsh plugin --profile <profile> remove dsh-http-probe

Configuration

Config is validated by the plugin at load (no schema dependency): unknown fields and non-positive-integer limits fail loud.

Tool

• Name: http_probe
• Parameter: path only — must start with a single /; no .. segments, query, fragment, or control characters.

Example: Use the http_probe tool to GET /ok.

Security

• The model cannot choose a full URL: only path is exposed.
• baseUrl is deployment configuration.
• Redirects are not followed automatically.
• This is a fixed-target probe, not a general-purpose arbitrary-URL fetcher.

Compatibility / Developer Preview

• Requires the host to provide @deepseek-ai/cordis@4.0.1 and @deepseek-ai/dsh-tools@0.1.0-rc.5 (hard peer dependencies).
• @deepseek-ai/dsh-tools@0.1.0-rc.5 is not currently published on the npm registry, therefore:
  • Prebuilt tarball installation is verified and supported.
  • Git source self-contained install is not verified and is currently blocked.
  • Do not substitute a different @deepseek-ai/dsh-tools version; keep the exact host version.

Development

• The public tsconfig.json carries no machine-specific paths and is used by pnpm build.
• While @deepseek-ai/dsh-tools@0.1.0-rc.5 types are unavailable from the registry, local development uses a gitignored tsconfig.local.json that extends ./tsconfig.json with a paths mapping to a local rc.5 declaration build; run pnpm build:local to use it.
• tsconfig.local.json never ships in the tarball and never enters Git.
