keyword-memory

Extracts keywords and named entities from user messages and returns them as contextual memories. Gives agents awareness of conversation topics without requiring external NLP libraries.

Extraction Techniques

Plain keywords: Splits words, filters English stopwords (~50 words), removes short tokens
Capitalized phrases: Detects multi-word proper nouns and mid-sentence capitalized words
Emails and URLs: Regex pattern matching
Numbers with units: e.g. 500ms, 10GB, 3.5GHz
Dates: YYYY-MM-DD, MM/DD/YYYY, DD.MM.YYYY formats
Technical terms: camelCase, snake_case, dotted identifiers (e.g. os.path)

Results are deduplicated and capped at 10 keywords.

Hooks

Hook	Script	Description
ingest	`hooks/ingest.py`	Extracts keywords from the user message and returns them as a memory fragment

Example Output

{"type": "ingest_result", "memories": [{"content": "[keyword-memory] Key topics: GPT-4, machine_learning, data pipeline, https://example.com"}]}

If no meaningful keywords are found, returns an empty memories list.

Usage

Installed automatically when enabled in agent configuration. No external dependencies required (stdlib only).
