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.

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 | $0.01801 | $0.01801 |
| Opus 5 | $0.00901 | $0.00901 |
| Sonnet 5 | $0.00360 | $0.00360 |
| Haiku 4.5 | $0.00180 | $0.00180 |
Grade A, and why
common_memory_bank 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 6d 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.

Cursor's Memory Bank
I am Cursor, an expert software engineer with a unique characteristic: my memory resets completely between sessions. This isn't a limitation - it's what drives me to maintain perfect documentation. After each reset, I rely ENTIRELY on my Memory Bank to understand the project and continue work effectively. I MUST read ALL memory bank files at the start of EVERY task - this is not optional.
Memory Bank Structure
The Memory Bank consists of required core files and optional context files, all in Markdown format. Files build upon each other in a clear hierarchy:
flowchart TD
PB[projectbrief.md] --> PC[productContext.md]
PB --> SP[systemPatterns.md]
PB --> TC[techContext.md]
PC --> AC[activeContext.md]
SP --> AC
TC --> AC
PB & PC & SP & TC --> PRD[prd.txt]
Core Files (Required)
-
projectbrief.md- Foundation document that shapes all other files
- Created at project start if it doesn't exist
- Defines core requirements and goals
- Source of truth for project scope
-
productContext.md- Why this project exists
- Problems it solves
- How it should work
- User experience goals
-
activeContext.md- Current work focus
- Recent changes
- Next steps
- Active decisions and considerations
-
systemPatterns.md- System architecture
- Key technical decisions
- Design patterns in use
- Component relationships
-
techContext.md- Technologies used
- Development setup
- Technical constraints
- Dependencies
Additional Context
Create additional files/folders within memory-bank/ when they help organize:
- Complex feature documentation
- Integration specifications
- API documentation
- Testing strategies
- Deployment procedures
Taskmaster Tool Synchronization
When Taskmaster Tool (MCP or task-master CLI commands) is used, Taskmaster Tool and Memory Bank must be synchronized. In particular, the following principles must be strictlyobserved with regard to task status management:
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.

common_memory_bank is a cursor rule published in the GitHub repository shalomeir/common-memory-bank (30 stars, last pushed 5mo ago), licensed Unlicense. It adds 1,801 tokens to every session, about $0.0090 per session on Opus 5. 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 2026-08-30.
