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/jaychouya/memoryagent/memory-sidecargit clone --depth 1 https://github.com/jaychouya/MemoryAgentWhat 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 | $0.00775 | $0.00775 |
| Opus 5 | $0.00387 | $0.00387 |
| Sonnet 5 | $0.00155 | $0.00155 |
| Haiku 4.5 | $0.00077 | $0.00077 |
Grade A, and why
memory-sidecar 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.

权威层级（Ground Truth）
| 优先级 | 来源 | 用途 |
|---|---|---|
| 1 | 本轮已注入的记忆块（memory_recall / memory_export 的 prompt_block） |
用户偏好、项目决策、禁忌、可复用事实 |
| 2 | 当前工作区代码、终端输出、用户附件 | 运行时状态 |
| 3 | 官方文档、README | API、版本、配置细节 |
| 4 | 模型训练知识 | 仅参考，须与 1-3 核对 |
冲突规则： 运行时状态以 2 为准；偏好与历史决策以 1 为准；版本敏感细节以 3 为准。注入记忆与主观假设冲突时，注入记忆优先。
行动前检查（每轮最多 recall 一次）
- 清点：上下文中是否已有
[user]/[feedback]/[project]/[reference]记忆块？ - 匹配：当前问题是否已被这些记忆覆盖？
- 决策：已覆盖 → 直接引用并回答，禁止为「验证」再调
memory_recall、搜仓库或读文件重找同一事实。 - 未覆盖或话题已切换 → 调用一次
memory_recall(query=用户当前问题)。
每轮流程
- 按上文「行动前检查」决定是否需要
memory_recall（可省略user_id/project_id，服务端从工作区自动推导）。 - 回答时：只引用 recall 结果；标记
is_stale的记忆先核实再当事实。 - 回答后：用户明确偏好/禁忌/项目决策/链接时，调用
memory_store（memory_type: user | feedback | project | reference）。 - 纠错：用户说「记错了」「忘记…」「不要再记住…」时，用
memory_delete或memory_update修正，并复述ide_notice。 - 需要整段注入系统提示时：
memory_export→ 使用prompt_block或cursor_rules_block。 - 上下文里出现
memory_retrieve_blob(ref_id=ccr_…)时，用该工具取回完整 tool 输出再分析。
IDE 内可感知（记→用→信）
memory_recall/memory_store返回里的ide_notice字段：用一句话告诉用户「召回了几条 / 是否写入」。- 项目内
.memoryagent/status.json记录最近一次 recall/store（用户可在资源管理器打开查看）。 - 写入或召回后，在回复末尾用一行中文复述
ide_notice，让用户知道记忆层在工作。

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-sidecar is a cursor rule published in the GitHub repository jaychouya/MemoryAgent (68 stars, last pushed 2mo ago), licensed MIT. It adds 775 tokens to every session, about $0.0039 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.
