Lifts the RFC 010 § Deferred restriction that the server had to launch in the
workspace ("cwd must equal the launch directory"). An editor can now open any
project folder, and N concurrent sessions over one connection can each target a
different directory.
- packages/acp: drop the `cwd === process.cwd()` guard in validateWorkspaceParams
(keep "must be absolute" — the cwd becomes the session header / bash workdir),
and drop the persisted-cwd-vs-launch-dir check in session/load (a resumed
session keeps its original header.cwd, so its bash tools run in its workspace).
- packages/tool-bash: the missing link — default the bash workdir to the calling
agent's session cwd (`exec.agent.session.header.cwd`) via a new resolveWorkdir
helper. An explicit model `workdir` still wins; a relative one resolves against
the session cwd. This is the only correct spot for multi-session: N sessions
share one ctx.bash executor, so the workdir must come per-call from exec.agent,
not executor config. Falls back to the executor default when no session cwd is
available (preserves non-ACP behavior).
- Trust: the cwd originates from the ACP client (the user's editor) at
session/new — same trust level as the old launch dir; no new untrusted-input
path. `additionalDirectories` (scope widening / sandbox) stays rejected.
- Tests: bridge accepts any absolute cwd + records it on the header; session/load
honors the persisted cwd; bash defaults to / resolves relative against the
session cwd; two sessions with different cwds each run bash in their own dir;
non-absolute cwd still rejected. 100% per-file coverage maintained.
- Docs: RFC 010 status + § Deferred cwd bullet marked RESOLVED; acp README adds a
Per-session cwd section; tool-bash + example READMEs and e2e comments updated.
DeepSeek Harness
Monorepo for the DeepSeek Harness group.
Projects
- DeepSeek Code — DeepSeek's coding agent product.
Development
This monorepo is built on the Cordis framework (vendored as source under vendor/), microkernel-style: everything is a plugin.
pnpm install
pnpm run test # vitest
pnpm run demo:echo # runnable echo-agent example (no API key needed)
pnpm run demo:coding # the real DeepSeek coding agent (needs DEEPSEEK_API_KEY)
For humans, start with the development guide for local setup, hooks, environment variables, and quality gates, then read the architecture design before package work. Local context lives in packages/ and vendor/.
For agents, follow AGENTS.md.
