PROJECT README
NoAtMark text hygiene as a DeepSeek Harness (dsh) plugin.
Everything-is-a-plugin: this plugin gives your dsh agent four text-hygiene tools, backed by the same deterministic engines behind noatmark.com.
| Tool | What it does |
|---|---|
sanitize_text |
Strip invisible/zero-width characters and flag prompt-injection + hidden-text signals. |
scan_text |
Report invisible characters (with code points + positions), injection patterns, and hidden text. |
clean_format |
Clean LLM formatting artifacts (blank lines, stray fences, trailing spaces) — meaning untouched. |
sanitize_csv |
Escape CSV formula injection (OWASP): = + - @ prefixes get a leading quote. |
All processing is deterministic and local — no data leaves your machine.
Add this plugin to your dsh Web UI. If you're running from a source checkout, use a cordis.yml patch:
- insert:
- id: noatmark
name: noatmark-dsh-plugin
or point at the source directly (absolute path):
- insert:
- id: noatmark
name: '/path/to/noatmark-dsh-plugin/src/index.ts'
Start dsh with the patch:
npx @deepseek-ai/dsh web --patch ./cordis.yml
In a dsh session, ask the agent to use a tool, e.g.:
Sanitize this pasted text before you summarize it.
Scan this file for invisible characters.
Clean the formatting of this AI output.
Escape this CSV before saving it.
