v0.5.0 — lite/full delegate tools, bounded concurrency, usage reporting

Install in one line — add this to ~/.codex/config.toml, restart Codex, done:

[mcp_servers.dsh_subagent]
command = 'npx'
args = ['-y', 'github:mbj733/dsh-subagent-mcp']
startup_timeout_sec = 60

Prefer no npx? The .tgz asset below installs with
npm i -g <asset-url>.

First public release.

Two delegate tools with explicit cost tiers

• subagent_dsh (lite) — skills + shell + file editing, ~9k input tokens per run
• subagent_dsh_full — adds the MCP servers from overlay.yml, ~300k input tokens

Per-call controls

• wait_sec (return a task id instead of blocking), imeout_sec (hard limit, process-tree kill, partial answer returned)

ead_only (instruction + detection, explicitly not a kernel sandbox)

• ormat: json for programmatic consumption

Operational

• bounded concurrency with a FIFO queue (default 2)
• results report tokens, tool calls, startup_ms / work_ms, �xit_code, �rror_code
• oversized answers spill to state/results/.md
• optional
  otify-hook.mjs surfaces finished tasks through host hooks

Safety

• configuration is delivered as dsh --patch overlays: existing DSH profiles are never rewritten
• the server creates its own dsh-subagent profile from the shipped headless template

Verified

• real end-to-end runs: answer returned in 2.9s, startup 1.67s / work 1.19s, tokens in 9073 / out 2
• skills and AGENTS.md confirmed inherited by the child
• cancel kills the whole process tree; zero orphans
• bad cwd, queueing, session-id status and timeout paths all exercised
