Continual Learning for AI Coding Agents
Your agent forgets everything between sessions. Continual learning fixes that.
The Loop
Experience → Capture → Reflect → Persist → Apply ↑ │ └───────────────────────────────────────┘
Quick Start
Install the hook (one step):
cp -r hooks/continual-learning .github/hooks/
Auto-initializes on first session. No config needed.
Two-Tier Memory
Global (~/.copilot/learnings.db ) — follows you across all projects:
-
Tool patterns (which tools fail, which work)
-
Cross-project conventions
-
General coding preferences
Local (.copilot-memory/learnings.db ) — stays with this repo:
-
Project-specific conventions
-
Common mistakes for this codebase
-
Team preferences
How Learnings Get Stored
Automatic (via hooks)
The hook observes tool outcomes and detects failure patterns:
Session 1: bash tool fails 4 times → learning stored: "bash frequently fails" Session 2: hook surfaces that learning at start → agent adjusts approach
Agent-native (via store_memory / SQL)
The agent can write learnings directly:
INSERT INTO learnings (scope, category, content, source) VALUES ('local', 'convention', 'This project uses Result<T> not exceptions', 'user_correction');
Categories: pattern , mistake , preference , tool_insight
Manual (memory files)
For human-readable, version-controlled knowledge:
.copilot-memory/conventions.md
- Use DefaultAzureCredential for all Azure auth
- Parameter is semantic_configuration_name=, not semantic_configuration=
Compaction
Learnings decay over time:
-
Entries older than 60 days with low hit count are pruned
-
High-value learnings (frequently referenced) persist indefinitely
-
Tool logs are pruned after 7 days
This prevents unbounded growth while preserving what matters.
Best Practices
-
One step to install — if it takes more than cp -r , it won't get adopted
-
Scope correctly — global for tool patterns, local for project conventions
-
Be specific — "Use semantic_configuration_name=" beats "use the right parameter"
-
Let it compound — small improvements per session create exponential gains over weeks
