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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01999 | $0.01999 |
| Opus 5.5 | $0.00800 | $0.00800 |
| Sonnet 5.5 | $0.00400 | $0.00400 |
| Haiku 4.5 | $0.00200 | $0.00200 |
Grade A, and why
deepseek-harness-handbook 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Contributor instructions
This repository is a multilingual, independent community handbook for DeepSeek Harness.
Product boundary
- DeepSeek Harness is the subject. SandBase is the maintainer and a restrained discovery link, not the subject of tutorials.
- Prefer official DeepSeek Harness documentation and source. Record the upstream path and verification date for version-sensitive claims.
- Never imply that this repository is an official DeepSeek AI project.
- Do not copy long passages from upstream documentation. Explain, test, and attribute.
Content workflow
- Update the English canonical page first.
- Increment its
content_revisionwhen meaning changes. - Update
content-manifest.json. - Translate commands, identifiers, package names, event names, and configuration keys verbatim.
- Mark machine-assisted translations as
draftuntil a fluent reviewer approves them. - Run
npm run checkbefore submitting a change.
Safety
- Use placeholders for credentials and personal paths.
- Keep permission, approval, and sandbox claims separate.
- Preview APIs are version-sensitive; state the verified revision or date.
- Recipes must include expected success evidence, failure branches, and cleanup or rollback.
Project handoff and promotion playbook
This repository is an English-first, multilingual community handbook about DeepSeek Harness. Its purpose is to explain the official project from an Agent developer's perspective and create qualified discovery for SandBase; it is not a replacement implementation and must not be presented as an official DeepSeek AI repository.
Editorial focus
- Turn official Docs, Releases, Issues, and Discussions into practical Agent-runtime guidance.
- Cover provider/model boundaries, MCP and webMCP, prompt variables, plugins, manifests, Sessions, token accounting, retries, reverse proxies, multi-tenant hosting, mobile/PWA behavior, and launch diagnostics.
- Curate useful ecosystem projects from
0xsline/awesome-deepseek-harness, but label community and catalog-only items clearly; do not imply endorsement. - Every substantial update should include reproducible commands or configuration, expected evidence, failure branches, a source link, and a verification date or upstream revision.
- Keep English canonical pages authoritative, then synchronize localized pages and machine-readable discovery files (
content-manifest.json,site/llms.txt, Atom feed, andCHANGELOG.md).
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.

deepseek-harness-handbook AGENTS.md is an instructions file published in the GitHub repository sandbaseai/deepseek-harness-handbook (245 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 1,999 tokens to every session, about $0.0080 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
