Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add instructions/labforgedev/copilot-memory-mcp/copilot-instructionsgit clone --depth 1 https://github.com/LabForgeDev/copilot-memory-mcpWhat it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00259 | $0.00259 |
| Opus 5 | $0.00130 | $0.00130 |
| Sonnet 5 | $0.00052 | $0.00052 |
| Haiku 4.5 | $0.00026 | $0.00026 |
Grade A, and why
copilot-memory-mcp copilot-instructions.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
GitHub Copilot Instructions — Memory Tools
You have access to a persistent memory MCP server (copilot-memory) at http://localhost:8000/sse.
Available tools
| Tool | When to use |
|---|---|
create_memory |
Save a new decision, convention, or finding |
search_memories |
Retrieve relevant context before answering |
update_memory |
Amend an existing memory when something changes |
delete_memory |
Remove stale or incorrect memories |
list_memories |
Browse all saved memories for a project |
Rules
- Always search before answering questions about architecture, conventions, or past decisions — call
search_memoriesfirst. - Always save new architectural decisions, agreed conventions, and non-obvious workarounds.
- Set
project_nameto the current repository name on every call. - Prefer
update_memoryover delete + recreate when content changes. - Use consistent tags:
architecture,convention,bug,performance,devops,security,testing,tooling. - Do not save temporary debug notes or information already obvious from the code.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
