Nori CLI ACP Roadmap

This roadmap is about Nori's ACP client work, not ACP in the abstract. The goal is to keep the client simple, fast, and predictable while we fill in the highest-value protocol features.

Product Roadmap

Status key: ✅ done working well, 🔵 now current focus, 🟡 next near-term, ⚪ later planned but not near-term.

At a high level:

done                          now                          next                         later
 ●─────────────────────────────●────────────────────────────●────────────────────────────●──────────────→
core loop                     session forking              session config               agent auth
local agent registry          images/resources             official agent registry      multi-session
session lifecycle             message queue                                             unstable ACP

Product area	Status	User value	Next work	Maintainer note
File attachments	✅ done	users can reference code and docs	keep @ path reference behavior stable	agents read referenced paths through ACP filesystem requests
Local agent registry	✅ done	custom agents can be registered	keep local config registration simple	ACP Registry should complement this, not replace it yet
Session lifecycle	✅ done	navigate previous sessions	keep behavior stable while forking work continues	load, list, resume, lazy indexing, and undo are already working
Session continuity	✅ done	users can continue prior work	keep resume listing, speed, and metadata stable	context/usage metadata and session_info_update are finished
Session forking	🔵 now	sessions can branch and form trees	finish fork and tree-oriented flows	keep native ACP behavior ahead of local stand-ins
Image attachments	🔵 now	users can send visual context	capability-aware image routing and transcript fidelity	images reach ACP, but the path needs polish
Queued messages	🔵 now	users can keep typing during work	finish backend handling for queued turns	TUI support exists, but ACP backend behavior needs tightening
Session configuration	✅ done	agents can expose useful controls	custom options like thinking/effort level and plan/build modes	keep this driven by agent-provided config, not hardcoding
Agent discovery	🟡 next	custom agents are easier to find	support the official ACP Registry	local config registration already works
Agent-driven auth	⚪ later	agents can own login/logout flows	auth methods and logout	wait until lifecycle, config, and registry are settled
Multi-session UX	⚪ later	users can move across active work	multi-session support and navigation	keep this separate from single-session lifecycle cleanup
Steering messages	⚪ later	users can redirect an active turn	wait for ACP support, then design Nori behavior	unsupported by ACP today
Subagent UX	⚪ later	group subagent updates	wait for ACP support, then design Nori behavior	unsupported by ACP today
Experimental ACP	⚪ later	adopt new protocol ideas carefully	elicitation, NES, session/delete, provider endpoint work	do not let draft features complicate the core client

ACP Feature Appendix

This table keeps the roadmap grounded in the current ACP spec and draft surface. It is dependency-facing detail, not the main structure of the project roadmap.

Notes

• This reflects our current understanding as of April 2026.
• "Done" means done enough for initial usage within Nori, not necessarily that every implementation detail is perfect.
• We will keep preferring fewer special cases and more native ACP behavior as we iterate.
