memory-protocol

memory-protocol is a cursor rule for Cursor from boparaiamrit/skills-by-amrit. It costs 746 tokens per session, scanned A, original, MIT.

A set of project rules for keeping memory across agent sessions, including startup checks and records of decisions, bugs, architecture changes, and handoffs.

In plain words
What is it for?
Use it to read prior project memory, record significant decisions and technical gotchas, update architecture notes, and preserve handoff information.
Why use it?
It prevents important project context from being lost when a conversation ends or a new session begins.

Cursor rule for Cursor

Written for Cursor: a Cursor rule (.mdc).

Token cost

What 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.

Security

Grade A, and why

memory-protocol 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.

Persistent Memory Protocol

Session Start — ALWAYS DO THIS

At the start of EVERY conversation involving project work:

  1. Check if .planning/MEMORY.md exists in the project root
  2. If it exists, read it silently before doing anything else
  3. Also read .planning/handoffs/LATEST.md if it exists
    • If LATEST.md doesn't exist, that's OK — skip this step
  4. Acknowledge context briefly: "From memory: we're working on [X], last session we [Y]"
  5. Use this context to inform ALL your work in this session

During Session — CAPTURE AS YOU GO

On Significant Decisions

Decisions worth capturing: architecture, technology choices, trade-offs, breaking changes. Append to .planning/decisions/DECISIONS.md:

## [DATE] — [Topic]
**Decision:** [What was decided]
**Rationale:** [Why]

On Discovering Bugs/Gotchas

Append to .planning/context/gotchas.md:

## [Component]
**Issue:** [Description]
**Workaround:** [How to handle]

On Architecture Changes

Update .planning/context/architecture.md with the change.

Auto-Save Reminder

After completing significant milestones, proactively ask:

"Would you like me to save progress to memory now?"

Session End — ALWAYS DO THIS

When significant work is complete or the user indicates session end:

  1. Archive previous handoff: Move LATEST.md to handoffs/_history/YYYY-MM-DD-HHMMSS.md
  2. Create session log: .planning/sessions/YYYY-MM-DD-session-N.md
    • Session numbering: N = (highest N for today) + 1, or 1 if first session today
  3. Write handoff: .planning/handoffs/LATEST.md with:
    • Summary, current state, next steps, blockers, gotchas
  4. Update .planning/MEMORY.md with new information
  5. Compress if MEMORY.md exceeds 300 lines

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.
