Harness reference
Supported coding harnesses, native capability differences, and host-specific behavior.
woostack's skill logic should work in any harness that loads and follows skills. The harnesses in this section are the integrations woostack explicitly documents. Native capabilities such as subagent dispatch, working-directory placement, model selection and routing, PTY execution, profile isolation, and credential boundaries differ by host. A missing capability degrades visibly or blocks the workflow; woostack never pretends the integration succeeded.
Hermes is not a harness in this list. It is an external engineer that may drive one persistent OMP process; the top-level Hermes guide owns that boundary. Woostack installs in the coding harness, and the harness retains implementation, worker, and process authority.
Capability comparison
| Harness | Model and effort routing | Working directory | Host behavior |
|---|---|---|---|
| omp (Oh My Pi) | Host-owned roles through init-managed project workers; no per-call model knob | Passed when exposed; explicit cwd pins when needed | OMP-owned model identity, workers, and recovery |
| opencode | Per-call model routing | Passed when exposed; prompt pin always | Provider exhaustion surfaces as an error |
| Claude Code | Per-call model and supported effort routing | No per-call cwd; subagent self-pins | Provider exhaustion surfaces as an error |
| Codex | Per-call locally; one model per Codex Action job | Passed when exposed; prompt pin always | Local and CI routing differ |
| Cursor / Composer | Session model; no per-call routing | No per-call cwd; subagent self-pins | Requested tiers collapse to the session model |
| Antigravity CLI | One model per session | No per-call cwd; subagent self-pins | Cannot run headless in ephemeral CI |
For normal in-process OMP use, host-owned role routing selects init-managed project workers while OMP owns concrete models, provider credentials, and fallback policy. External Hermes does not change that installation or worker boundary.
The model-tier reference
defines the shared fast, standard, and deep policy. Each page below links to its canonical
host reference for the exact mechanics.
omp (Oh My Pi)
Host-owned worker routing and project-scoped OMP workers.
opencode
Per-call routing through the runtime subagent primitive.
Claude Code
Task-based dispatch with per-call models and prompt-pinned worktrees.
Codex
Local per-call routing and Codex Action's single-session mode.
Cursor / Composer
Parallel dispatch with session-model tier collapse.
Antigravity CLI
Dynamic subagents, single-session routing, and interactive authentication.
