* fix: add PEP 561 py.typed marker to all Python packages
Add empty py.typed marker files to all 13 Python packages that were
missing them. Only hindsight-integrations/autogen already had one.
Per PEP 561, packages that wish to support type checking must include
a py.typed marker file. Without it, type checkers (mypy, pyright) treat
the package as untyped and skip all inline type annotations.
Fixes#965
* fix: ensure py.typed markers survive client regeneration
Add touch commands in generate-clients.sh to recreate PEP 561 py.typed
marker files after the OpenAPI generator runs, since the script deletes
and regenerates the hindsight_client_api directory.

* fix(deps): address critical and high severity security vulnerabilities
Bump vulnerable dependencies to patched versions across the monorepo:
Python (critical/high):
- fastmcp >=2.14.0 → >=3.2.0 (SSRF, path traversal, OAuth confused deputy, command injection)
- langchain-core >=1.2.11 → >=1.2.22 (path traversal in legacy load_prompt)
Python (low):
- cryptography >=46.0.5 → >=46.0.6 (incomplete DNS name constraint enforcement)
- pygments: add >=2.20.0 pin (ReDoS via GUID regex)
Node.js:
- serialize-javascript ^7.0.3 → ^7.0.5 (CPU exhaustion DoS)
- handlebars: add >=4.7.9 override (JS injection via AST type confusion)
- path-to-regexp: add >=0.1.13 override (ReDoS via route params)
- brace-expansion: add version range override (process hang/memory exhaustion)
Also adds type: ignore comments for FastMCP 2.x private attribute access that
ty now flags since FastMCP 3.x removed _tool_manager (guarded by try/except
and hasattr at runtime).
Regenerated all lock files across API, integrations, and tests.
* fix(deps): add ajv v8 scoped overrides for schema-utils and ajv-keywords
The global ajv ^6.14.0 override caused schema-utils and ajv-keywords to
receive ajv v6, but they require ajv v8 (for dist/compile/codegen). Add
scoped overrides to ensure these packages get ajv v8 while the global
override remains for packages that need v6.
* fix(tests): remove stateless_http from FastMCP() constructor calls
FastMCP 3.x no longer accepts stateless_http in the constructor. The
tests call tools directly without HTTP transport, so the parameter is
not needed.
* fix: update MCP tests for FastMCP 3.x _tool_manager removal
FastMCP 3.x removed _tool_manager. Tests now use
_local_provider._components for sync tool dict access and
mcp.list_tools() for async filtered tool listing.
* fix: resolve docusaurus build failures (ajv overrides + missing blog date)
- Remove global ajv ^6.14.0 override and scoped ajv-keywords/schema-utils
overrides that caused webpack compilation errors manifesting as
"Cannot read properties of undefined (reading 'date')" during SSR
and "these parameters are deprecated" warnings. Natural version
resolution (v6.12.6+ for v6 consumers, v8+ for v8 consumers) already
satisfies the security fix (>= 6.12.3).
- Add missing date frontmatter to learning-capabilities blog post.
* chore: regenerate openapi spec and docs skill
* fix(llamaindex): use uuid for document_id and sync version metadata
- Replace timestamp-based document_id with uuid4 hex to prevent
collisions on rapid retains (timestamp_ms can duplicate in tight loops)
- Sync __version__ in __init__.py to match pyproject.toml (0.1.2)

* fix(docs): pass memory to run() instead of ReActAgent constructor
LlamaIndex 0.14.x ReActAgent does not accept a memory parameter in
its constructor — it's silently dropped via **kwargs. Memory must be
passed to agent.run(memory=...) where AgentWorkflow picks it up.
Also fixes the undefined `tools` variable (now `tools=[]`).

* fix(llamaindex): strip ReAct reasoning traces from retained assistant messages
HindsightMemory.put/aput now extracts only the final Answer: text from
assistant messages containing ReAct reasoning (Thought:/Action:/Observation:
prefixes), preventing internal reasoning traces from polluting long-term memory.

* fix(llamaindex): fix docstring example to pass memory to run()
The HindsightMemory class docstring showed the broken pattern of passing
memory= to the ReActAgent constructor, which silently drops it. Updated
to show the correct pattern: pass memory to agent.run().

* refactor(llamaindex): merge two packages into single hindsight-llamaindex
Merge `llama-index-tools-hindsight` and `llama-index-memory-hindsight` into
a single `hindsight-llamaindex` package following our naming convention.
- Rename package to `hindsight-llamaindex` (Python module: `hindsight_llamaindex`)
- Move HindsightToolSpec and HindsightMemory into the same package
- Delete `llamaindex-memory/` directory
- Add CI test job for llamaindex integration
- Update docs, blog post, and integrations.json
* fix(blog): update llamaindex blog post for merged package
- Move date to 2026-03-30
- Add HindsightMemory (automatic BaseMemory) pattern
- Fix "bank must exist first" pitfall — mission auto-creates
- Align all code examples with docs page
- Update architecture diagram to show both patterns
* fix(docs): add llamaindex/openai icons, rename Codex
- Add llamaindex.png and openai.png icons
- Rename "OpenAI Codex CLI" to "Codex" in integrations.json and docs
- Use openai.png icon for Codex integration
* feat: add LlamaIndex integration for Hindsight
Add hindsight-llamaindex package providing persistent memory tools for
LlamaIndex agents via the native BaseToolSpec pattern. Includes retain,
recall, and reflect tools, a convenience factory, global config, full
test suite, docs page, blog post, and integrations.json entry.

* fix: address PR review feedback for llamaindex integration
- Fix ReActAgent API: from_tools() → constructor, chat() → await run()
- Add create_bank step to all quickstart examples
- Add production patterns section to docs (tags, error handling, bank lifecycle)
- Add memory scoping recommendation to README
- Add when-not-to-use section to blog post
- Add LlamaIndex compatibility tests (agent acceptance, FunctionTool.call)
- Fix self-hosted auth wording in cookbook notebook

* fix: use async client methods and asyncio.run() for runnable examples
- Use await client.acreate_bank() instead of sync create_bank() to
avoid "event loop already running" errors in notebooks and async contexts
- Wrap plain Python examples in async def main() + asyncio.run(main())
so they are copy-paste runnable as scripts
- Add Jupyter notebook tip to docs showing top-level await pattern
- Bank lifecycle example in docs now uses async acreate_bank

* fix: add async tool methods to avoid event loop conflicts
HindsightToolSpec now provides both sync and async tool implementations
using LlamaIndex's (sync_fn, async_fn) tuple pattern in spec_functions.
Async agents (ReActAgent, etc.) use aretain/arecall/areflect natively,
avoiding the "Timeout context manager should be used inside a task"
error that occurred when sync _run_async() was called from within an
active event loop.
- Add aretain_memory, arecall_memory, areflect_on_memory async methods
- Extract shared kwargs builders (_retain_kwargs, _recall_kwargs, etc.)
- spec_functions now uses tuples: [("retain_memory", "aretain_memory"), ...]
- Tests verify tools have both sync fn and async fn set
- Notebook verified end-to-end with nbclient against local Hindsight

* chore: remove blog post from integration PR
The blog post will be pulled in separately from its own PR.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* Address PR review: add context label, document_id auto-gen, bank mission, graceful errors
- Add `retain_context` param (default: "llamaindex") as source label on retain ops
- Auto-generate `document_id` as `{session_id}-{timestamp_ms}` when not provided
- Add `retain_async` param (default: True) for non-blocking retain processing
- Add `mission` param for automatic bank creation/management on first use
- Change error handling from raising HindsightError to graceful log + return message
- Add per-operation timeout constants in _client.py
- Add `context` and `mission` fields to config.py and configure()
- Update docs: document as standalone package (not LlamaHub), new params, patterns
- Tests: 51 passing (up from 34), covering all new features

* Restructure to LlamaIndex namespace packages + add BaseMemory implementation
Tools package (llama-index-tools-hindsight):
- Restructured from hindsight_llamaindex/ to llama_index/tools/hindsight/
- Import: from llama_index.tools.hindsight import HindsightToolSpec
- Follows PEP 420 implicit namespace package convention
- Removed retain_async param (client.retain() doesn't support async_processing)
Memory package (llama-index-memory-hindsight):
- New package: llama_index/memory/hindsight/
- HindsightMemory(BaseMemory) for automatic memory
- put() auto-retains user/assistant messages to Hindsight
- get(input) auto-recalls relevant memories, prepends as system message
- Graceful error handling, bank mission management, document_id generation
- 28 unit tests passing
Both packages follow LlamaIndex community conventions for future LlamaHub submission.
