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 rules/barisercan/cursorrules/memory-bankgit clone --depth 1 https://github.com/barisercan/cursorrulesWhat 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 | $0.00458 | $0.00458 |
| Opus 5 | $0.00229 | $0.00229 |
| Sonnet 5 | $0.00092 | $0.00092 |
| Haiku 4.5 | $0.00046 | $0.00046 |
Grade A, and why
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 2d 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.

Memory Bank System
Memory resets between sessions. MUST read ALL memory bank files at start of EVERY task.
actions:
-
type: enforce message: | MEMORY BANK PROTOCOL
CRITICAL: Memory bank files are the ONLY resource available after session reset. Agent must understand EVERYTHING just by reading these files. No other context exists.

WORKFLOW:
- Start: Read ALL memory bank files
- Work: Update documentation after changes
- Cleanup: Remove outdated info, keep minimal
UPDATE TRIGGERS:
- New project patterns discovered
- After significant changes
- User says "update memory bank"
- Context needs clarification
BREVITY RULE:
- Each file as brief as possible
- 1 sentence better than 100
- Clean out outdated info
- No unnecessary details
examples:
- input: "update memory bank" output: "Review ALL files, update current state, remove outdated info"

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.

memory-bank is a cursor rule published in the GitHub repository barisercan/cursorrules (35 stars, last pushed 1y ago), licensed MIT. It adds 458 tokens to every session, about $0.0023 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.
