Added an embedText projection for remember() so stored transcripts can remain readable while embeddings, FTS indexing, and embedding-model rebuilds use marker-free text. Updated coding-agent retention to pass the marker-free projection and strip retained protocol markers from recall display.
Fixes#4395
Added timeout-backed AbortSignals to update, Hindsight, and Smithery fetch calls so stalled endpoints abort instead of hanging indefinitely.
Added regression coverage for the timeout signals on the exposed command/client paths.
Fixes#4229
- Added an extractText override to pi-mnemopi remember paths so stored content and mined facts can use different text.
- Routed coding-agent mnemopi retention to store the full transcript while extracting only user-authored turns.
- Tightened deterministic Instruction extraction to require an explicit I/you subject.
Fixes#3372
- Standardized elision markers across all tool outputs and filters to use cohesive `[...N [type] elided...]`, `[...Nln elided...]`, and `[...xB elided...]` syntax.
- Updated documentation, prompts, and test expectations to reflect the unified elision format.
- Improved transcript viewer robustness by preventing content aliasing through path-inclusive signature hashing.
- Added logic to clear stale transcript content when associated session files are deleted, accompanied by verifying test cases.
- Added session-domain modules and exports for session-entries, context, listing, loader, and migrations.
- Changed persistence to async append writes plus writeTextAtomic, removing sync line APIs.
- Added compaction-aware session context rebuild with dangling tool-call cleanup.
- Added resumable session resolution with status inference, id/stem/suffix matching, and backup recovery.
Sent Hindsight retain timestamps with local timezone offsets and supplied timestamps for automatic and queued retains. Added regression coverage for client serialization and backend timestamp propagation.\n\nFixes #2363
Bare-repository worktrees resolve their git common dir to the bare repo
itself (for example /repos/foo.git), not to a directory literally named
.git. The first fix only collapsed non-bare linked worktrees, so bare
worktree layouts still fell back to each individual worktree root.
Return the shared commonDir for bare repositories from both
repo.primaryRoot and repo.primaryRootSync, update project-label docs,
and cover two worktrees attached to one bare repository in the
hindsight bank regression test.
Fixes#2232
Per-project-tagged scoping derived projectLabel() from
path.basename(cwd), so linked git worktrees of one repo landed retains
under distinct project:<basename> tags and recall (recallTagsMatch:
"any") missed cross-worktree memories.
- utils/git.ts: add sync sibling primaryRootSync to git.repo, walking
.git + commondir with sync file reads (no subprocess), returning null
outside a repo. Mirrors the async primaryRoot resolution.
- hindsight/bank.ts: projectLabel() resolves the primary checkout root
via primaryRootSync and basenames that; falls back to the cwd
basename when outside a repo. Sync only, so computeBankScope keeps
its sync API and the async cascade that sank #1218 is avoided.
- test/hindsight-bank.test.ts: regression block builds a real repo +
git worktree add fixture and asserts both produce the same
project:<primary> tag and per-project bank id, plus a non-repo
fallback case.
- CHANGELOG: Fixed entry under Unreleased.
Fixes#2232
Project-tagged Hindsight mental-model seeds now use project-qualified ids and legacy bare ids only satisfy the matching project tag. The injected mental-model block also filters tagged models to the active project while retaining untagged models.\n\nFixes #2218
Coalesced synchronous Hindsight routing setting hooks into one serialized
session rebuild so cwd reloads and multi-setting updates cannot have
multiple continuations capture the same old state and leak fresh
session listeners.
Also re-read the current state after awaiting the previous queue flush
before installing the replacement state, so an unexpected concurrent
owner cannot leave the actual current state undisposed.
Fixes#1902
Mid-session edits to hindsight.bankId / bankIdPrefix / scoping kept the
active HindsightSessionState pinned to the bank selected at session
start, so retain/recall/reflect calls landed in the stale bank. Settings
hooks now fire onHindsightScopeChanged; the backend rebuilds the
primary state against the recomputed scope, disposing the previous one
after flushing its queue so queued tool-initiated retains still land in
the bank they were enqueued for.
Also:
- Renamed ensureBankMission to ensureBankExists. The old version
skipped creation entirely when bankMission was blank, so the first
mental-model POST (auto-seed) could land against a never-PUT bank.
Bank creation is now idempotent and unconditional, and runs before
mental-model bootstrap.
- Fixed AgentSession.dispose to flush the retain queue BEFORE clearing
the session state pointer. Reversed, HindsightRetainQueue.#doFlush's
identity guard would see the cleared pointer and drop the spliced
batch with a 'session vanished' warning.
- Snapshotted hindsightScopeCallbacks before iterating because each
rebuild subscribes a fresh callback inside the same fire; iterating
the live Set would spin.
Fixes#1902
prepareRetentionTranscript only skipped messages whose stripped content
trimmed to the empty string, so single-character assistant turns like
".", "...", or pure whitespace survived as
`[role: assistant]\n.\n[assistant:end]` blocks. Repeated across a
session (each tool-call-only or thinking-only turn produces one) these
polluted the Hindsight bank, wasted retain tokens, and degraded recall
relevance. extractMessages and flattenMessagesForRecall had the same
gap, only checking length/trim truthiness.
Add hasSubstantiveContent in hindsight/content.ts (a single
\p{L}/\p{N} test) and apply it from all three call sites so retain,
recall, and pre-compaction inputs require at least one letter or digit
per message. Single-char real replies ("y", "4", "ok") still pass.
Fixes#1806
- Updated plan-mode and hindsight session state lookups to use Array.findLast for selecting the latest assistant or user message.
- Updated postmortem callback iteration to use Array.toReversed before mapping cleanup callbacks.
- Removed export leakage by demoting many helper and const symbols to module-local scope.
- Renamed underscore-prefixed internals and cache fields, then updated related references and `satisfies never` checks.
- Deleted obsolete logic branches and helpers, including harmony-stream interruption flow and unused benchmark runtime helpers.
- Updated Biome config and manifests by broadening lint coverage and removing an unused `@napi-rs/cli` dev dependency.
- Adjusted tests and utilities to use renamed test helpers and remove redundant private test-only helpers/locals.
- Added `HindsightSessionState` to `AgentSession` and bound hindsight lifecycle hooks to session state.
- Removed global hindsight state/queue handling and replaced it with per-session `HindsightRetainQueue` batching and scoped flushing.
- Reworked recall, reflect, and retain tools to use `session.getHindsightSessionState()` instead of sessionId-based lookup.
- Updated SDK/task/backend/controller flows to pass `session`/`parentHindsightSessionState`, scope `/memory` behavior, and document it in changelog.
- Added mental-model settings and config defaults for enablement, auto-seed, refresh interval, and render budget.
- Added built-in mental-model seeds and scope-aware rendering with `<mental_models>` extraction, truncation, and tag handling.
- Added `/memory mm` aliases and handlers for list, show, refresh, history, seed, reload, and delete commands.
- Added client APIs and bootstrap/cache wiring so snippets refresh and inject into prompts on startup.
- Added tests covering seed scope behavior, rendering caps, diffs, and backend/session reload behavior.
- Added per-session retain queues with size/time auto-flush, recursive drain, and lifecycle flushes on end/clear/enqueue.
- Changed `hindsight-retain` to validate session state, enqueue writes, and return `Memory queued.` immediately.
- Added `notice` event support and handlers that route error/warning/status messages with source-aware formatting.
- Updated client and tests with shared request mapping, `RequestOptions`, `buildMemoryItem`, and expanded batch/list/doc APIs.
- Added an optional `aliasOf` link and a `pickPrimaryState` helper to track reusable parent Hindsight state.
- Updated task-depth subagent startup to reuse the latest primary state's bank, client, config, tags, and missions while returning silently when no parent exists.
- Skipped alias states in recall-snippet selection and enqueue so auto-recall/retain work only on the parent session.
- Removed the `@vectorize-io/hindsight-client` dependency from both package manifests.
- Added a local `HindsightApi` client and changed `createHindsightClient` to instantiate it.
- Replaced `HindsightClient` imports/types with `HindsightApi` across backend, bank, and tests.
- Implemented `HindsightApi` `#request` handling with `fetch`, safe JSON parsing, and `HindsightError` on failures.
- Added `hindsight.scoping` and `HINDSIGHT_SCOPING` with global, per-project, and per-project-tagged modes.
- Migrated legacy `raw.hindsight` handling to scoping-based behavior and removed deprecated `dynamicBankId`/`agentName` keys.
- Replaced `deriveBankId` with `computeBankScope`, returning `bankId` plus optional retain/recall tags by mode.
- Forwarded scoped tags through memory ops so recall and retain/reflect calls use `tags`, `tagsMatch`, and `recallTags`.
- Validated `scoping` values from env/settings, warning and defaulting to `per-project-tagged` when invalid.
- Standardized Hindsight context output to emit `<memories>` blocks and updated retention stripping to remove both `<memories>` and legacy `<hindsight_memories>`/`<relevant_memories>` tags.
- Renamed built-in Hindsight tool entry points and labels from `hindsight_retain`/`hindsight_recall`/`hindsight_reflect` to `retain`, `recall`, and `reflect`, including tool availability checks.
- Added a new optional `beforeAgentStartPrompt` hook to `MemoryBackend` and implemented it in the Hindsight backend to recall long-term context for the first turn.
- Updated `AgentSession` startup flow to inject the recalled context into the turn-specific system prompt before the first response is generated.
- Preserved `<hindsight_memories>` tags in Hindsight developer instructions and added tests for first-turn injection and state caching.
- Added `memory.backend` and `hindsight.*` settings schema with migration from `memories.enabled` legacy mode.
- Added Hindsight memory backend runtime modules for resolved config, client creation, bank ID derivation, and state lifecycle.
- Added off/local/hindsight backends and resolver wiring across SDK, commands, and compaction context.
- Added `hindsight_recall`, `hindsight_reflect`, and `hindsight_retain` tools with schema validation and backend gating.
- Added Memory tab metadata and symbols to expose backend selection in the settings UI.
