Closes activeloopai#364 Adds first-class Kiro CLI support to Hivemind — sessions from kiro-cli are now captured into shared memory exactly like Claude Code, Cursor, and Cowork sessions. ## What's added ### src/kiro/kiro-ingest.ts Tails ~/.kiro/sessions/cli/*.jsonl and maps Kiro's JSONL format to Hivemind session rows: Prompt → user_message AssistantMessage → assistant_message + tool_call (per toolUse block) ToolResults → tool_result (per toolResult block) Session ID is derived from the transcript filename (UUID). Secrets are redacted per-field before entry assembly (same pattern as the activeloopai#361 fix in cowork-ingest). Idle sessions trigger a wiki summary + skillify pass via the existing summarizeIdleSessions pattern. Lock file prevents double-insertion when multiple MCP processes are running. ### src/cli/install-kiro.ts Registers the shared hivemind MCP server into ~/.kiro/settings/mcp.json (non-destructive merge — preserves bettervibe, supabase, posthog, etc.). Supports install and uninstall; refuses to clobber a malformed config. ### Wiring - src/mcp/server.ts: startKiroIngestLoop() called on MCP server startup - src/cli/index.ts: installKiro/uninstallKiro wired to `hivemind kiro install|uninstall` - src/cli/util.ts: "kiro" added to PlatformId and PLATFORM_MARKERS (marker: ~/.kiro) ## Tests - tests/claude-code/kiro-ingest.test.ts — 30 tests: extractText, entriesForLine (all 3 kinds + edge cases), secret redaction (OpenAI key, GitHub PAT, Anthropic key), summarizeIdleSessions - tests/cli/install-kiro.test.ts — 8 tests: install creates config, merges non-destructively, is idempotent, rejects malformed JSON; uninstall removes only hivemind entry, deletes file when empty, is a no-op - tests/cli/cli-util.test.ts: updated allPlatformIds snapshot to include kiro 67/67 new tests passing. Pre-existing failures on main unchanged.

- Line 39: Update the configuration validation around the parsed config and
cfg.mcpServers to reject arrays as well as non-object values, using
Array.isArray checks. Throw the existing invalid-shape error before any mutation
or file write, so invalid root or mcpServers configurations are reported without
modifying the file.
In `@src/kiro/kiro-ingest.ts`:
- Around line 343-350: Update the error handling around the summary spawn and
forceSessionEndTrigger calls so either failure is reported as an unsuccessful
callback rather than swallowed, and ensure the checkpoint recorded near the
callback completion is advanced only after the corresponding task starts
successfully. Keep summary and skillification progress independent by using
separate checkpoints where their outcomes can differ, referencing the
surrounding callback flow and forceSessionEndTrigger.
- Line 177: Update the lock lifecycle around the stale-holder check, heartbeat,
and release callback to retain an ownership token or file descriptor for the
created lock. Before refreshing or deleting LOCK_PATH, verify it still
identifies that same lock, and perform the identity check atomically with
deletion where possible; otherwise skip the operation when ownership changed.
Preserve the existing reclamation behavior while preventing delayed processes
from modifying or deleting a reclaimed lock.
- Around line 269-276: Validate toolUse and toolResult block shapes in
entriesForLine before dereferencing their data fields, including required data,
name, and toolUseId values. Skip malformed or unsupported blocks without
throwing so the ingest pass can continue and state.processedLines can be
updated. Preserve normal entry creation for valid KiroToolUseBlock and
tool-result blocks.
- Around line 434-436: Update the JSON-parse failure handling in the ingestion
loop around JSON.parse(raw) so an unterminated final record does not increment
processed; preserve the existing retry behavior by leaving that record
unprocessed for the next poll, while retaining current handling for
newline-terminated records.
- Around line 120-143: Update loadState and saveState so state writes use a
temporary file followed by an atomic rename, and invalid or unreadable existing
state fails closed by preserving the last valid state or stopping ingestion.
Only a missing state file may initialize { processedLines: {} }; remove the
current fallback that resets malformed state to an empty watermark, and ensure
callers of loadState handle the failure without ingesting from line zero.

Reject array-shaped configuration objects.
Both checks accept arrays as objects. If the root config or mcpServers is an array, assigning hivemind adds a named array property that JSON.stringify omits. The installer then reports success, but Kiro remains unconfigured.
Require plain records and report the invalid shape without modifying the file.
Proposed validation
- return parsed && typeof parsed === "object" ? (parsed as McpConfig) : {};
+ if (!parsed || typeof parsed !== "object" || Array.isArray(parsed)) {
+ throw new Error(`mcp.json at ${CONFIG_PATH} must contain a JSON object.`);
+ }
+ return parsed as McpConfig;Apply the same Array.isArray check to cfg.mcpServers.

Preserve lock identity during reclamation and release.
The stale holder check and both deletions operate only on LOCK_PATH. A delayed process can resume after another process reclaims and recreates the lock. Its heartbeat can then refresh the new lock, and its release callback can delete that new lock. Both processes can enter ingestion and append duplicate rows.
Keep an ownership token or file descriptor. Before each heartbeat and deletion, verify that the current path still identifies the same lock.
Based on learnings, pathname-only stale-lock deletion has a TOCTOU race unless deletion re-verifies lock identity.

CI failure: dir-config-single-source.test.ts rejected kiro/kiro-ingest.ts because it constructs DeeplakeApi without routing through loadRoutedConfig(). This is intentional — Kiro has no directory context, same as cowork-ingest. Added to the ALLOWLIST with an explicit reason. Also adds `hivemind kiro install | uninstall` to the CLI help text and the supported-assistants message (CodeRabbit review feedback).
Four bugs fixed:
1. install-kiro.ts: Reject array-shaped root config and mcpServers.
typeof [] === 'object' is true in JS, so arrays passed the old check.
A named property set on an array is invisible to JSON.stringify, meaning
the hivemind entry would silently not be written.
2. kiro-ingest.ts: Atomic state write + fail-closed on invalid state.
saveState now writes to a temp file then renames atomically, preventing
partial-JSON corruption on process kill. loadState now treats a corrupt
or invalid-shape file as a hard error (returns null, skips ingestion for
the tick) rather than resetting processedLines to {} and replaying every
transcript from line zero with new UUIDs, which creates duplicate rows.
3. kiro-ingest.ts: Validate toolUse/toolResult block data before deref.
A block with kind='toolUse' but no .data field passed isBlock() and then
threw on tb.data.name. The outer catch returned before incrementing
processed, so every subsequent poll retried the same line forever,
blocking all later transcript content.
4. kiro-ingest.ts: Don't advance watermark for unterminated final line.
split('\n').filter(Boolean) keeps a partial last line Kiro is still
writing. The old code incremented processed on JSON.parse failure
regardless of position — the final line was permanently skipped.
Now only non-final failed-parse lines advance the watermark.

Closes #364
What and why
Kiro CLI (
kiro-cli) sessions are written to~/.kiro/sessions/cli/<uuid>.jsonlbut have no way to land in Hivemind shared memory — there are no hooks, no plugin API. This PR adds a Kiro harness using the same transcript-tailing approach as the Cowork ingester.What's in this PR
