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 5.1 | $0.00000 | $0.01257 |
| Opus 5.5 | $0.00000 | $0.00503 |
| Sonnet 5.5 | $0.00000 | $0.00251 |
| Haiku 4.5 | $0.00000 | $0.00126 |
Grade A, and why
.github 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Memory Bank MCP Server - Copilot Agent
About This Project
Memory Bank MCP is a Model Context Protocol (MCP) server that provides AI assistants with persistent memory across sessions. It allows storing and retrieving project context, tracking progress, logging architectural decisions, and managing active context through a set of MCP tools.
Tech Stack: TypeScript 5.1.6 | Bun (build, test, package manager) | Node.js runtime target | MCP SDK v1.6.1
Repository: @diazstg/memory-bank-mcp
Skills
This project has the following specialized skills available in .github/skills/:
- code-quality - Clean code principles, SOLID patterns, code review checklists, and metrics targets specific to this TypeScript MCP server project
- typescript-best-practices - Type-first development, strict mode patterns, ESM imports, exhaustive switches, error handling, and project-specific TypeScript conventions
- bun-development - Bun runtime, package management, build configuration, test runner usage, and Node.js compatibility considerations for this project
- testing-strategy - Testing patterns using
bun:test, temp directory isolation, file system testing, MCP tool handler testing, and coverage targets - mcp-server-development - MCP protocol patterns, tool definition/handling, file system abstraction, ETag concurrency, and guide for extending the server

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.

.github is a skill published in the GitHub repository diaz3618/memory-bank-mcp (1 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,257 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

apex-context-management
UTILITY SKILL — Two-mode context-window management. RUNTIME: artifact compression (full/summarized/minimal) for orchestrator and codegen agents. AUDIT: post-mortem analysis of Copilot debug logs (token profiling, redundancy, hand-off gaps) for 11-Context Optimizer. WHEN: "context optimization", "token budget"…
tiered-memory
Three-tier agent memory model (hot/cold/wiki) for context reduction per spawn.
nap
Context hygiene — compress, prune, archive .squad/ state.
linglu-discipline

clean-architecture-dotnet
Use when domain logic leaks into API/Infrastructure, project references violate layer boundaries, or you need to decide between CQS (always), CQRS bus (complex domains), and DDD patterns (invariants and events).
outside-in-tdd
Use when writing tests from the outside-in, defining behavior before code, or any feature where tests should start from observable business behavior and let internal design emerge.
