Task Memory (Experience Memory)
Task Memory is JiuwenSwarm's built-in experience system that allows the Agent to retrieve, record, and consolidate lessons from past tasks — avoiding repeated mistakes and reusing effective solutions in future tasks.
Configuration
Configure in config/config.yaml:
task_memory:
enabled: true # Master switch
retrieval_algo: ACE # Retrieval algorithm: ACE | ReasoningBank | ReMe
summary_algo: ACE # Summary algorithm: ACE | ReasoningBank | ReMe
llm_model: ${TASK_MEMORY_LLM_MODEL} # LLM model for task memory (empty = main model)
embedding_model: ${TASK_MEMORY_EMBED_MODEL}
api_key: ${TASK_MEMORY_API_KEY}
api_base: ${TASK_MEMORY_API_BASE}
When enabled: true, the Agent gains the three tools described below.
Tools
experience_retrieve
Retrieve relevant past experience based on a query.
| Parameter | Type | Description |
|---|---|---|
query |
string | Describe the current task or question; the system matches the most relevant experience |
Returns memory_string (readable text) and retrieved_memory (structured list).
Recommended: call this at the start of every task to check for reusable experience.
experience_learn
Record a key finding, rule, or insight from the current task and consolidate it into the experience store.
| Parameter | Type | Required | Description |
|---|---|---|---|
params.content |
string | Yes | The experience content to record |
params.section |
string | No | Category label, default general |
params.when_to_use |
string | No | When to apply this experience |
params.title |
string | No | Experience title |
params.description |
string | No | Detailed description |
params.query |
string | No | Associated query |
params.label |
string | No | Custom label |
params.tools_used |
list | No | Tool call outcomes, e.g. [{"tool": "web_search", "status": "success"}] |
Recommended: call once before the final reply. Recording failed tool calls is especially valuable.
experience_clear
Wipe all stored task memory from task-data.json.
⚠️ Only call when the user explicitly asks to clear. Always confirm first.
Storage
Experience data is persisted in workspace/agent/task-data.json. Even when the external experience service is unavailable, local persisted data is still accessible (returns persisted_only status).
When the external service is healthy, retrieval results merge both local persisted data and service-side data.
Retrieval Algorithms
| Algorithm | Description |
|---|---|
| ACE | Default algorithm; embedding-similarity-based retrieval |
| ReasoningBank | Reasoning-enhanced retrieval; suited for complex reasoning chains |
| ReMe | Reflection-based retrieval; focuses on learning from failures |
Environment Variables
| Variable | Description |
|---|---|
TASK_MEMORY_LLM_MODEL |
LLM model for task memory |
TASK_MEMORY_EMBED_MODEL |
Embedding model for task memory |
TASK_MEMORY_API_KEY |
API key for task memory |
TASK_MEMORY_API_BASE |
API base URL for task memory |
