using-goodmemory

Instructions for using GoodMemory, a service that stores and recalls durable project context across coding sessions.

In plain words
What is it for?
Use them when past project context could affect the task, and when saving an explicit fact, decision, reference, or blocker for later sessions.
Why use it?
They help an agent recover earlier decisions, preferences, failures, and project history without treating recalled information as more reliable than current code or tests.

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.

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

using-goodmemory 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

Using GoodMemory

GoodMemory is fallible supporting context. The user's latest instruction, the current repository, and current test or runtime evidence take precedence.

For every GoodMemory tool call, pass the current project absolute path as cwd. Do not set or invent a fixed workspace id. This keeps sessions in the same project connected while isolating different projects.

When earlier decisions, user preferences, prior failures, or project history could materially affect the task, call mcp__goodmemory__goodmemory_get_context with one concrete question. Recall is on demand; do not call it mechanically on every turn.

If expected context is missing or a surfaced memory looks wrong, call mcp__goodmemory__goodmemory_trace_recall with the same query. Use goodmemory_search_index followed by goodmemory_get_records only when the task needs exact records instead of the rendered context.

The mcp__goodmemory__goodmemory_remember tool is available after installation, but Kimi Code approval still governs unapproved MCP calls. Persist only a durable, explicit fact, preference, decision, reference, or blocker. Store one clear statement per call. Use role: "user" for user-originated content and role: "assistant" for a conclusion produced by the agent. Report whether the result was accepted, merged, or rejected.

Never persist secrets, credentials, tokens, raw transcripts, private file contents, or unconfirmed inferences. Do not imply that session-start text automatically reads or writes memory; it only supplies these operating rules.

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.

using-goodmemory is a skill published in the GitHub repository hjqcan/GoodMemory (17 stars, last pushed 10d ago), licensed MIT. It adds 18 tokens to every session and 358 once invoked, about $0.0001 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.
