Memory & Context 15

Control durable knowledge or standing context available to agents.

ExtellaLets agents reuse programs that earlier threads already wrote: search them by meaning, run them on your machine, save new ones. A thread that asks in different words still finds the saved program and runs it without writing code. Programs run on your computer through Extella Desktop and can read local files there; a run takes about 10 seconds. Later threads and other bb projects that use the same Extella agent see the same library. Needs an Extella account with an API key and agent id, and Extella Desktop on the machine that runs programs.Memory & ContextAnvar BakiyevNew
Scoped SkillsGive each skill only to the agents, models and projects that should have it, so image skills reach Codex and stay out of Claude Code. Each skill carries a list of agents plus optional model and project globs such as gpt-5* or *my-org/*, and a thread receives only the skills that match its agent, model and project. A preview shows what a thread on any agent, model and project would get. Import skill folders from the BB machine, or ask a thread to list or change a scope; a bb scoped-skills CLI does the same. Needs no account, API key or network access.Memory & ContextPritam SharmaNew
SkillsSee every skill a thread's agent can use, where each one comes from and what it says, and add one to the chat from the panel or composer. A Skills tab in the thread's side panel groups them by origin — the project, the repository, your personal folder, an admin folder, a Claude Code or Codex plugin, or bb itself — and shows each one's SKILL.md, rendered, with its path on disk. Claude Code, Codex and Hermes threads have their skill folders read the way that agent reads them, in worktrees and on other enrolled machines too, so a name defined twice is listed once, under the copy the agent uses. Add to chat puts the skill in the message box as the same pill bb's / menu inserts and sends nothing, and a Skills button with a live count, or a keyboard command, opens the same list in bb's pop-up above the message box. Threads on other providers list bb's own skills and what bb's / menu offers. Needs bb 0.45 or later, and no account, key or network access.Memory & ContextGustavo AmbrozioNew
SpecsGive every project one shared set of spec documents that agents read before they change code. Specs link to any number of projects and live in one store, so they survive branches, worktrees, and new checkouts. Each project thread receives a compact index of its specs — pinned documents always, changed documents when they changed — and pulls full text only when an agent asks. Select a quote to leave a comment; open comments come back from the read tool as review feedback instead of silent edits. Every spec gets its own chat thread where the agent reads before answering and applies agreed changes with a revision check. Agents also get the bb specs command line and tools for search, annotate, attach, detach, and delete. Runs entirely inside BB: no account and no external service.Memory & ContextPeter Abu-Ekpeshie9
Workspace SkillsConnect external skill repositories and workspace folders directly to BB without hardcoding paths or copying files. Discovers nested skill packages across your configured directories and registers them into BB's shared skill roots. Discovered skills appear in the slash menu and session instructions across all projects and providers. Configure paths via Settings or the workspace-skills CLI subcommand. Changes to skills in their source repositories reflect immediately without re-installing.Memory & ContextVanDalkvist18
