dsh-gpt-file-discipline

dsh-gpt-file-discipline is a small DeepSeek Harness host plugin that silently switches one conditional system-prompt section by model route. It waits for downstream waterfall listeners before matching, so it uses the provider and model chosen for the exact step rather than an earlier route candidate.

• GPT route (provider is exactly codex and the model starts with gpt-): appends the file-discipline section.
• DeepSeek route (the provider or the model starts with deepseek): appends the DeepSeek thought-language section.
• Any other route: returns the downstream assembly completely unchanged.

The plugin registers no static prompt section. The only prompt content it can add is the one appended section after a route matches, so an unmatched route costs no extra context, token, filtering, or section overhead.

Install for a DSH profile

After this repository is published, add it to a DSH profile with the GitHub package spec:

dsh plugin --profile <profile> add github:youxi-huang/dsh-gpt-file-discipline

The package declares cordis.patch.yml as its bundle patch. Its official patch-entry array mounts one plugin row:

- insert:
    - id: gpt-file-discipline
      name: dsh-gpt-file-discipline

Cordis validates the exported Schemastery Config, applies its defaults, and owns listener registration and cleanup.

Defaults

Route	Match	Section	Text
GPT	provider codex + model prefix gpt- (case-insensitive)	model-file-discipline	File-discipline guidance (below)
DeepSeek	provider or model prefix deepseek (case-insensitive)	route:deepseek-thought	Thought-language guidance (below)

GPT text:

Local documents span many loosely related systems and include dormant or retired material, so do not browse files speculatively: locate the relevant source first, read only the smallest necessary passages, and stay strictly within the user-defined scope.

DeepSeek text:

when you thought,thought in ENGLISH,start with "We need..."

Attribution note: the DeepSeek line is community-shared text from a Bilibili comment section, not original work by this package's author. Its effectiveness is anecdotal; keep it only if it proves useful.

If the matching route's section already exists, the plugin leaves the assembly unchanged. DeepSeek is checked before GPT.

Configuration

Cordis configuration patches are top-level patch-entry arrays. A configured insert for both routes looks like this:

- insert:
    - id: gpt-file-discipline
      name: dsh-gpt-file-discipline
      config:
        provider: codex
        modelPrefix: gpt-
        gptText: Use only the designated project sources.
        sectionName: route:gpt-file-discipline
        deepseekProviderPrefix: deepseek
        deepseekModelPrefix: deepseek
        deepseekText: '**when you thought,thought in ENGLISH,start with "We need..."**'
        deepseekSectionName: route:deepseek-thought
        caseSensitive: false

Field	Default	Meaning
provider	codex	Exact provider required for the GPT route.
modelPrefix	gpt-	Model prefix required for the GPT route.
promptText	file-discipline text	GPT text, kept from the original plugin API.
gptText	unset	Optional alias that overrides promptText when supplied.
sectionName	model-file-discipline	Section name appended for the GPT route.
deepseekProviderPrefix	deepseek	Prefix for provider-based DeepSeek matching.
deepseekModelPrefix	deepseek	Prefix for model-based DeepSeek matching.
deepseekText	DeepSeek text above	Section text appended for the DeepSeek route.
deepseekSectionName	route:deepseek-thought	Section name appended for the DeepSeek route.
caseSensitive	false	Enables case-sensitive prefix matching.

Text fields must be nonblank strings. Section names must be 1–128 characters, start with a letter or digit, and contain only letters, digits, ., _, :, or -. caseSensitive must be a boolean.

Profile installation applies the bundle to the DSH host, so the inserted plugin is host-wide. For preset-only use, make the package resolvable to DSH without adding its bundle layer, then add an ordinary plugin row to that preset's top-level entry list:

- id: gpt-file-discipline
  name: dsh-gpt-file-discipline
  config:
    provider: codex
    modelPrefix: gpt-
    sectionName: route:gpt-file-discipline

One practical route is to install the package as a dependency and then remove dsh-gpt-file-discipline from that profile's dsh.profile.bundles list before mounting the row in the preset. Do not use a map keyed by package name: agent preset compositions are top-level arrays of plugin rows.

Uninstall

Remove it from the same DSH profile using the installed package name:

dsh plugin --profile <profile> remove dsh-gpt-file-discipline

This removes the bundle-managed Cordis row; unloading the plugin disposes its listener registration.

Development

The committed index.js is the package entry point; no build or prepare step is required.

npm run check:syntax
npm test
