* Add structured JSON logging support
Add HINDSIGHT_API_LOG_FORMAT environment variable to configure log output
format. Options are "text" (default, human-readable) and "json" (structured).
JSON format outputs logs with a "severity" field that cloud logging systems
can parse for proper log level categorization. Also writes to stdout instead
of stderr so log levels are correctly interpreted.
* Rename GCPJsonFormatter to JsonFormatter
The "Test memory" example is too short for the LLM to extract
meaningful facts from, causing the test to silently fail (0 memories
created). Replace with "Alice works at Google as a software engineer"
which has enough context for fact extraction.
Fixes test examples in:
- get-skill installer (local and cloud modes)
- hindsight-embed configure output
- skills.md documentation
* doc: update expired Slack invite link
* feat: add cloud mode to skill installer for team memory sharing
Adds support for Hindsight Cloud in the skill installer, enabling teams
to share memories about a codebase. Changes include:
- Add `--mode cloud` option to get-skill installer
- Install hindsight CLI binary for cloud mode (via get-cli)
- Configure ~/.hindsight/config with API URL and key
- Generate cloud-specific SKILL.md with team-aware guidance
- Distinguish between project conventions and individual preferences
- Update skills.md documentation with cloud setup instructions
Cloud mode workflow:
1. Team admin creates a bank in Hindsight Cloud
2. Each developer runs: curl ... | bash -s -- --mode cloud
3. All team members share the same memory bank
4. Knowledge retained by one member benefits everyone
* Fix: Load extensions in server.py for multi-worker deployments
When running with multiple workers (--workers 2), uvicorn uses
`hindsight_api.server:app` import string instead of passing an app
object. The server.py module was not loading tenant/operation validator
extensions, causing authentication bypass in production.
This fix:
- Adds extension loading to server.py matching main.py behavior
- Sets extension context on tenant extension for schema provisioning
- Adds comprehensive unit tests for server.py extension loading
The tests specifically verify:
- TENANT extension is loaded when HINDSIGHT_API_TENANT_EXTENSION is set
- OPERATION_VALIDATOR is loaded when configured
- Extensions are passed to MemoryEngine constructor
- Extension context is set on tenant extension
- Server works correctly without extensions configured
* Add unit tests for main.py extension loading (single-worker path)
* ci: frozen uv sync
* fix: add missing authorization parameter to get_agent_stats in CLI
The generated Rust client was updated with an authorization header
parameter for get_agent_stats, but the CLI code wasn't updated.
Previously, most methods in HindsightClient would silently return
undefined when API calls failed (e.g., connection refused). Only
the `recall` method had proper error checking.
This change adds a `validateResponse` helper method and applies it
consistently to all API methods:
- retain
- retainBatch
- recall
- reflect
- listMemories
- createBank
- getBankProfile
Now all methods properly throw an error with details when the API
request fails, instead of returning undefined.
* fix: misc perf improvements
* more tests
* fix test
* fix: update test files for new extract_facts_from_text signature
- Replace test_fact_extraction_token_analysis with test_fact_extraction_basic_analysis
using inline sample content instead of external file
- Update test_fact_extraction_output_ratio.py to unpack 3 return values
(facts, chunks, usage) instead of 2
* fix: make temporal tests more flexible for LLM variation
- test_temporal_absolute_conversion: check occurred_start field instead of
requiring specific text in facts
- test_date_field_calculation_yesterday: make assertions conditional on
having temporal data, add more content for better extraction
- test_temporal_ordering: reduce minimum required facts from 3 to 2
Call ensure_embedding_dimension after running migrations for tenant
schemas. This ensures the embedding column dimension matches the
model's dimension, which may differ from the default 384 dimensions
used in the initial migration.
Without this fix, using embedding providers with different dimensions
(e.g., Cohere's embed-english-v3.0 with 1024 dims) would fail with
"expected 384 dimensions, not 1024" errors on tenant schemas.
The /v1/default/banks/{bank_id}/stats endpoint was missing the
request_context parameter and tenant authentication call, causing
it to query the public schema instead of the tenant's schema.
This resulted in stats always returning zeros for multi-tenant
deployments since the data lives in tenant-specific schemas.
Added request_context dependency and _authenticate_tenant() call
to properly set the tenant schema before querying stats.

* feat(mcp): add async_processing parameter to retain tool
Add async_processing parameter (default: True) to the MCP retain tool
to allow non-blocking memory storage. When True, memories are queued
for background processing and the tool returns immediately. When False,
the tool waits for completion before returning.
This matches the async behavior available in the HTTP API.

* feat(mcp): add list_memories and reflect tools
Add two missing MCP tools to achieve feature parity with HTTP API:
- list_memories: browse memories with pagination and full-text search
(equivalent to GET /memories/list)
- reflect: LLM-based reasoning over memories with disposition awareness
(equivalent to POST /reflect)
Both tools follow the existing pattern with JSON string responses
and proper error handling.
* docs: improve CLAUDE.md with detailed architecture info
- Add memory types explanation (world, experience, opinion, observation)
- Document retain/ and search/ submodule structure
- Add commands for single test run, ruff format, ty type checking
- Note MCP server implementation in API layer
- Add optional environment variables section
- Clarify conventions (no Python files at root, npm workspaces)
* chore: add .mcp.json and .osgrep to gitignore
These are user-specific development tool configs that should not be committed.
* changes
* refactor(mcp): remove list_memories tool
The list_memories endpoint is for debugging/exploration, not agent use.
Agents should use recall for semantic search instead.
Feedback from maintainer: "this tool is misleading for the agent,
it should use recall, the list method is mostly for debugging and
exploration, not for real usage"

* refactor(mcp): remove list_banks and create_bank tools
These admin/orchestration tools are not needed for typical agent usage.
Agents work with a single configured bank via X-Bank-Id header.
MCP now exposes only core memory operations:
- retain: store memories
- recall: semantic search
- reflect: LLM reasoning over memories

* feat: Record LLM token metrics via Prometheus
Wire up the existing token metrics infrastructure to actually record
token usage from LLM calls. The MetricsCollector already had
record_tokens() method and Prometheus counters (hindsight.tokens.input,
hindsight.tokens.output), but they were never being populated.
Changes:
- Import get_metrics_collector in llm_wrapper.py
- Call record_tokens() after successful LLM calls for:
- OpenAI/Groq (using response.usage.prompt_tokens, completion_tokens)
- Anthropic (using response.usage.input_tokens, output_tokens)
- Gemini (using response.usage_metadata.prompt_token_count, candidates_token_count)
- Add test file to verify token metrics are recorded
Note: Ollama's native API doesn't return token usage, so metrics
are not recorded for that provider.
The token metrics will now be available via /metrics endpoint:
- hindsight_tokens_input_total
- hindsight_tokens_output_total
* feat: add per-request token usage tracking to retain and reflect endpoints
- Add TokenUsage model with input_tokens, output_tokens, total_tokens
- Return usage metrics in retain response (sync operations only)
- Return usage metrics in reflect response
- Update Python, TypeScript, and Rust clients
- Add API documentation for usage fields
- Add changelog entry
* feat(helm): add existingSecret support
Allow users to reference a pre-existing Kubernetes Secret instead of
having the chart create one. This enables better secret management
through tools like External Secrets Operator or sealed-secrets.
Usage:
```yaml
existingSecret: "my-pre-created-secret"
```
When existingSecret is set:
- The chart skips creating its own Secret resource
- Deployments reference the provided secret name
- Secret checksum annotation is omitted (no auto-rollout on changes)
The existing secret should contain all required keys:
- API secrets (e.g., HINDSIGHT_API_LLM_API_KEY)
- Control plane secrets
- postgres-password (if using external PostgreSQL)
* fix(helm): use envFrom for existingSecret and fix env var ordering
- Add envFrom to inject all keys from existingSecret as env vars automatically
- Fix POSTGRES_PASSWORD ordering (must be before DATABASE_URL for $(VAR) interpolation)
- Only use api.secrets/controlPlane.secrets when existingSecret is not set
- Update values.yaml documentation for existingSecret usage

Add automatic .env file loading using python-dotenv. This searches
the current working directory and parent directories for a .env file
and loads environment variables from it.
Uses override=True so .env file values take precedence over existing
shell environment variables, which is the expected behavior when
running from a project directory.
* Fix Python SDK not sending Authorization header
The Python SDK accepts an api_key parameter but never sends it as a
Bearer token in requests. The OpenAPI-generated Configuration class
stores the key in access_token, but auth_settings() returns an empty
dict because the OpenAPI spec doesn't define a security scheme.
This fix manually sets the Authorization header on the ApiClient,
bypassing the broken auth_settings() mechanism.
Tested against api.dev.hindsight.vectorize.io:
- Before: 401 "Authentication failed: API key required"
- After: Success
* chore: update Rust client Cargo.lock for CI verification
Run generate-clients.sh to sync Cargo.lock with current dependencies.
