unforgit-memory

A set of rules for using Unforgit to recall and save repository memory. Repository memory is stored context about a project's decisions, workflows, and past problems.

In plain words
What is it for?
It is for recalling memory before work and saving decisions, procedures, bugs, and project conventions through Unforgit tools.
Why use it?
It helps the agent recover relevant context at the start of a session and preserve important discoveries for later sessions.

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

unforgit-memory 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.

What it actually says

Unforgit Memory Integration

You have access to unforgit_recall and unforgit_add MCP tools for persistent repository memory across sessions.

1. Recall at the Start

At the beginning of every conversation, use the unforgit_recall tool with a query based on the user's first message to retrieve relevant context from past sessions.

Use recalled memories to avoid repeating past mistakes, follow known conventions, and apply previous decisions.

2. Save During the Conversation

Save memories as soon as something noteworthy happens — don't wait until the end.

Trigger a save with the unforgit_add tool immediately after:

  • A bug is found and fixed
  • An architectural or design decision is made
  • A non-obvious gotcha or workaround is discovered
  • A new convention or pattern is established
  • A deployment/setup procedure is figured out

Memory types

Type When Example
semantic Decisions, conventions, architecture facts "We use UTC timestamps everywhere"
procedural Workflows, how-tos, playbooks "To deploy: run make release, then kubectl apply"
episodic Bugs found, gotchas, observations "Found race condition in queue worker"

Rules

  • Keep text concise but self-contained — a future reader should understand it without extra context
  • Use meaningful tags for discoverability (e.g. ["auth", "bug"], ["deploy", "playbook"])
  • Prefer semantic for stable facts, procedural for how-tos, episodic for transient observations
  • Do NOT save trivial changes, obvious things, or info already in the codebase docs
  • Quality over quantity — only save what's genuinely useful for future sessions
  • Always write memory text in English, regardless of the language the user is speaking
Changes

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.

unforgit-memory is a cursor rule published in the GitHub repository MiguelMedeiros/unforgit (9 stars, last pushed 2d ago), licensed MIT. It adds 426 tokens to every session, about $0.0021 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 2026-08-31.
