MIT-licensed native DSH plugin providing model-driven Active Context Pruning (ACP): the model writes high-fidelity summaries, reclaims context space, and keeps compressed blocks recoverable and searchable.

01What can it help you accomplish?
Keep long DeepSeek Harness conversations from exhausting context by letting the model decide when and what to compress
High-fidelity, model-written summaries (file paths, decisions, errors preserved) that reclaim context space; compressed blocks stay recoverable via `decompress` and searchable via `search_context`
Developers and agent workflows running long or very-large-context tasks on DeepSeek Harness
Carry very long agent tasks to completion with conclusions compounding across turns
Each step builds on prior results; key conclusions stay available and keep compounding while context stays lean
Engineering and agent workflows that span many turns and very large contexts
02How to install into DeepSeek Harness
Prerequisites
- DeepSeek Harness (dsh) installed and running — this plugin is a DSH CompactionEngine backend
- Config lives under `~/.dsh`; first install needs a one-time file-write permission approval (stated in README)
Installation steps
- 01
Install from the DSH plugin store or run `dsh plugin --profile web add billion-context-dsh`
$ dsh plugin --profile web add billion-context-dsh
- 02
Restart `dsh` (the bundle layer composes at startup), then open a new session
$ dsh
Verify the integration
- In a new session, have the model call `acp_status` or run `/acp status` to prove the mount
03DSH integration and capability boundaries
Native CompactionEngine backend for DeepSeek Harness — install via `dsh plugin`, the ACP bundle patch auto-mounts on the host plane and registers the compress / decompress / search_context / acp_status model tools plus the `/acp` command for every mode.
Model-driven `compress` tool
a seq range of the session context→a high-fidelity, model-written summary that becomes a checkpoint node; originals stay in the append-only log
compress range is persisted to the append-only session log (surfaceOp: replace)originals are shadowed but retained and recoverable via `decompress``acp_status` context ledger
optional scope / view / tool / sort / limit drill-down params→CONTEXT BREAKDOWN + compressed-block ledger + nudge decision lines + Checkpoint seqs
`decompress` recovery and `search_context` retrieval
`bN` or compaction id from `acp_status` (decompress); a keyword (search_context)→`decompress` restores a compressed block's originals read-only; `search_context` returns matching block summaries and originals
`decompress` is a read-only restore that does not modify the log
04Who is it for? When not to use it?
Good for
- Developers and agent workflows running long or very-large-context tasks on DeepSeek Harness
- Engineering and agent workflows that span many turns and very large contexts
Not for
- Declares a peer dependency on `@deepseek-ai/dsh-compaction` (`^0.1.0-rc.6 || ^0.1.1-rc.1`); it must match a supported DSH version. Older published packages fail to install on DSH 0.1.1-rc.x and need the fixed release.
- Two `ctx.compaction` backends must not coexist in the same realm — you must disable host `compaction-basic` or the two backends conflict; keep exactly one context manager per agent.
- Both this plugin (v0.2.13) and DeepSeek Harness are in public beta; the README explicitly warns against production use and expects breaking changes.

06Frequently asked questions
How do I install billion-context-dsh into DeepSeek Harness?
Install from the DSH plugin store or run `dsh plugin --profile web add billion-context-dsh`, then restart `dsh` (the bundle layer composes at startup) and open a new session. The ACP bundle patch auto-mounts. Verify by having the model call `acp_status` or run `/acp status`.
Does it replace DSH's built-in auto-compaction?
No. It adds a model-driven ACP backend alongside DSH's built-in `compaction-basic`. You must disable host `compaction-basic` to avoid two `ctx.compaction` backends conflicting in the same realm; keep exactly one context manager per agent.
What model tools does it expose?
Four tools — `compress`, `decompress`, `search_context`, `acp_status` — plus the `/acp` slash command, all mounted on the host plane for every mode (standard / code / minimal / cordis / custom presets).
Is it production-ready?
No. Both this plugin (v0.2.13) and DeepSeek Harness are in public beta; the README explicitly warns against production use and expects breaking changes.
Can compressed context be recovered?
Yes. Compressed ranges become checkpoint nodes and originals stay in the append-only session log, so `decompress` restores them read-only and `search_context` searches block summaries and originals.
