Let agents read the next-work feed from the CLI

 - **SessionStart work-items nudge** — at every session start (Claude Code, Codex CLI, GitHub Copilot CLI, Gemini CLI, AWS Kiro CLI, Google Antigravity, Pi, OpenCode, and Cursor CLI's `cursor-agent`) `kcap` appends a short `## Work items` block carrying the current session id and a reminder to register the session with its work item via the [`kcap-workitems` MCP tools](#work-items-mcp-server-for-agents) (`declare_work_item`) and to declare structure as it is discovered (`declare_work_breakdown` for a parent→parts split, `declare_work_relation` for a `blocks`/`blocked_by` dependency). It rides the same per-harness delivery seam as the team-memory index, is composed independently of that index (so it never affects the index's once-per-session lease), and is shown only when `kcap-workitems` is actually registered for the harness and the tenant's plan includes Work Items. The plan comes from the last `X-Kcap-Plan` response header the CLI saw from the configured server, cached per server and shared by every harness on the machine — so a Free tenant is not told to call a tool that would refuse, and a plan change costs at most one stale nudge. An unknown plan (an older server, or one never reached) nudges. Opt out with `disable_workitems_nudge: true` in `~/.config/kcap/config.json` or `kcap config set disable_workitems_nudge true`.
 - **SessionStart plans nudge** — at every session start, on the same harnesses and through the same delivery seam as the work-items nudge, `kcap` appends a two-sentence `## Plans` block telling the agent to declare the plan, spec or design document it works from and the plan's task list through the [`kcap-plans` MCP tools](#plans-mcp-server-for-agents) (`declare_plan_document`, `set_plan_tasks`, `update_plan_task`, and `get_plan` to recover the list after compaction), carrying the current session id. It is shown only when `kcap-plans` is actually registered for the harness — for Claude Code, only when the installed plugin's `.mcp.json` names it, so a plugin installed before the server existed is never nudged toward a tool it lacks. Opt out with `disable_plans_nudge: true` in `~/.config/kcap/config.json` or `kcap config set disable_plans_nudge true`.
 - **SessionStart coordination notices** — at every session start (Claude Code / the generic route only) `kcap` advertises a `coordination_notices` capability on its `/hooks/session-start` request, and when the server has pending coordination notices for you — a heads-up that other people have in-flight work that may overlap yours (work-overlap / work-item adjacency) — it appends a `## Coordination notices` block to the session's injected context (`additionalContext`), one short line per notice (bounded, with a `+N more in the notification centre` tail when there are more). The same notices always reach the in-app notification centre and Slack regardless; this block just surfaces the most relevant few directly in the agent's context at the moment you start. Best-effort and fail-open (a missing or malformed field injects nothing, never blocking the hook), and the capability is advertised only on a live session start — never from `kcap import`/backfill. Opt out with `disable_coordination_notices: true` in `~/.config/kcap/config.json` or `kcap config set disable_coordination_notices true`; when set, the capability is not sent at all, so the notices stay in the notification centre / Slack only.
+- **SessionStart next work** — at every live session start (Claude Code / the generic route only) `kcap` advertises a `next_work` capability on its `/hooks/session-start` request, and when the server's next-work feed has rows for you it appends page one of it (up to three rows, each with its because-clause and link) inside a `<next-work-data>` block, followed by guidance to finish a listed item before starting new work, to declare a loose end with `declare_loose_end` at the moment something is deferred, and at completion to call `get_next_work` and tell the user what to consider next. Row text is sanitised and marked as data. The capability is never sent from a spooled replay or `kcap import`. Opt out with `disable_nextwork_nudge: true` in `~/.config/kcap/config.json` or `kcap config set disable_nextwork_nudge true`; when set, the capability is not sent and nothing is injected.
 - **First-run notice** — the session that runs `kcap setup` has no hooks, skills or MCP servers, because an agent reads those when it starts: it is not recorded, and it cannot run the guided tour. Setup leaves a one-shot marker, and the next session that starts with hooks in place opens with a short block saying setup completed and kcap's hooks are loaded, and offering the guided tour where the MCP servers it reads through are registered. It claims no more than that: not that this is the first recorded session (re-running setup arms it again), and not that the session reaches the server — a rejected token already has its own notice. It is armed only when setup installed something, claimed under the config lock so several agents starting at once deliver it once between them, and suppressed by `kcap config set disable_first_run_notice true` (which leaves the marker alone, so re-enabling before the next session still delivers it).
 - **Crash resilience** — if a `kcap` command hits an unexpected error it records the exception (with stack trace) to `~/.config/kcap/crash.log` (honours `KCAP_CONFIG_DIR`; size-capped) and exits cleanly instead of aborting. Hook and detached-generator commands the coding agent spawns **fail open** (exit 0, nothing surfaced to the agent); other commands exit non-zero with a one-line stderr message pointing at the log.

+It provides eleven tools:
 
 - **`declare_work_item`** — attach the current session (and its continuation chain) to a work item. Pass exactly one of `issue_key` (a tracker key such as `"AI-1234"`, an issue number in the session's repository such as `"#123"`, a qualified `"owner/repo#123"`, or a GitHub issue URL), `pr_number`, `work_item_id`, or `new_title` (creates a brand-new work item).
 - **`get_session_work_items`** — list the work items the current session is attached to.
+- **`get_next_work`** — what the user should work on next, ranked: others waiting on them first, then their own unfinished work (work items, interrupted sessions, loose ends), then new backlog. Each row carries a because-clause and one line of evidence, inside a `<next-work-data>` block whose text is sanitised and marked as data, followed by a freshness line (when the feed was read, how current its tracker state is, and any source that was not current). `repo_hash` defaults to the repository the server runs in; `limit` defaults to 5, max 20. On a server with next-work off it answers "Next-work is not enabled on this server." The server's instructions tell the agent to call it first whenever the user asks what to work on next, or before it proposes new work.
 - **`declare_loose_end`** — record one concrete piece of work this session leaves unfinished (`text`), so it appears in the user's next-work loose-ends ledger. Idempotent per session, owner and normalized text; the server refuses none-class text (`"none"`, `"n/a"`, …).
 - **`declare_work_breakdown`** — declare that a work item is broken into parts (`parent_id` + `part_ids`). Idempotent; a part has at most one parent, and every item must be visible to the caller — a part may live in a different repository than its parent.
 - **`retract_work_breakdown`** — detach the named parts from the parent.
