description

Save a durable fact, decision, or preference to memini. Use this skill proactively — do not wait to be asked — when the user says "remember this" or corrects you, after discovering a bug's root cause, after making an architectural decision, after learning a project convention or environment quirk, or whenever something learned in this session should outlive the session itself. The MCP tool is `memory_remember` on the bundled `memini` server.

remember (memini)

memini is a memory service. To save a fact, call the memory_remember MCP tool with:

• content (required) — the fact itself, atomic and self-contained
• tier — semantic for durable knowledge, procedural for how-to, episodic for events, working for transient notes; omit to let the server auto-classify
• tags (optional) — array of keywords for later search; tag a critical, always-relevant fact (the user's identity, a hard constraint) pinned so it surfaces in every session briefing
• metadata.category (optional) — a topic bucket so the memory can be browsed and filtered by subject later. This is orthogonal to tier: tier is the memory's kind, category is its topic. Any string is accepted, but pick one of the canonical values so filtering keeps working: architecture_decisions, anti_patterns, task_learnings, tooling_setup, bug_fixes, coding_conventions, user_preferences, dependency_decisions, performance_findings, security_constraints, testing_patterns, data_model, api_contracts, deployment_runbook, team_norms, domain_glossary, experiment_results.
• visibility (optional) — who should know this: project (default, this project only), personal (about the user, follows them everywhere), or an ancestor namespace name read off the memory_briefing Scope line (e.g. the team or org level) to share it up that chain. An unrecognized ancestor name errors listing the valid chain. Ignored for episodic/working writes — those always stay in the project regardless of visibility, so a session digest can never pollute a shared ancestor or the user's personal namespace.
• summary (optional) — short summary; defaults to first 200 chars of content
• confidence (optional) — 0..1 for durable (semantic/procedural) facts; omit to let it start uncorroborated and earn trust as the fact recurs. Durable facts gain confidence each time they're re-observed and lose it if never recalled, so saving a real, lasting fact as semantic (not working) is what lets it rise above one-off noise over time.

Result fields to check

• stored: false — the write was dropped by the episodic value gate (low-signal content, e.g. too short); not an error, just not saved. Rephrase with more substance if it's actually worth keeping.
• reinforced: true — the fact was already known: no new memory was created, the existing one was strengthened, and id names that pre-existing memory rather than anything you just wrote. Don't report it to the user as a new save, and be careful updating or forgetting that id.
• merge_hint — present when the content nearly duplicates an existing memory (merge_hint.similar_id, .similar_content, .score). The new content was still stored as its own memory; call the memory_update MCP tool with id: merge_hint.similar_id to fold the new information into the existing memory instead of leaving two near-duplicates, or ignore the hint to keep both as-is.
• degraded: "pending_embed" — embeddings were unavailable at write time, so the memory was stored without a vector (still keyword-searchable). It is backfilled with a vector automatically in the background — don't retry the write or treat this as a failure.

When to call

Do not wait to be asked. Capture at the moment of learning, not at session end.

• The user says "remember this", "save this", "don't forget", "note that", "next time", "going forward", "always/never do X". Call memory_remember FIRST, then acknowledge. On an explicit request, save unconditionally — even if it seems trivial, fleeting, or already stored (the server reinforces or merges near-duplicates; that is its job, not yours).
• The user corrects you. A correction IS a preference — capture it.
• You make an architectural decision (e.g. "we chose jose over jsonwebtoken for Edge compatibility"). Capture the why, not just the what.
• You discover a non-obvious bug or root cause worth flagging next time.
• You learn a project convention (test layout, deploy command, code style).
• You hit an environment or tool quirk (e.g. "tests need DOCKER_HOST unset on this machine").
• You learn a non-obvious command or workflow the project depends on.

When NOT to call

• Secrets, credentials, API keys, tokens — never, even on explicit request (this outranks the save-unconditionally rule; explain and point to a secret manager instead).
• Transient session state (what file you just opened, the branch you happen to be on mid-task).
• Task progress or TODO state — the plugin's session digests capture activity automatically; memories are for what stays true.
• Facts already in CLAUDE.md, .cursorrules, or project docs, or trivially recoverable from the codebase.
• Text the user is merely asking you to translate, edit, or summarize — content passing through your hands is not a fact about the user or project.

Examples

Call with tier semantic, metadata.category architecture_decisions:

The auth middleware uses jose rather than jsonwebtoken because we deploy to Cloudflare Workers, which can't run jsonwebtoken's C++ bindings.

Call with tier procedural:

To regenerate the embedding cache, run mise run embeddings:warm.

Call with tier episodic:

The 2026-06-09 outage was caused by a Postgres connection-pool exhaustion under load. The fix was raising max_connections to 200 and adding pgbouncer.

State facts, not commands — a memory is a claim about the world, not an instruction to your future self:

• Good: "User prefers pnpm over npm in all their projects" (declarative, visibility personal)
• Bad: "Always use pnpm" (a command — future recall cannot tell where it applies or why)
• Good: "TestAuthRefresh flakes because of a hard-coded 100ms timeout in auth/refresh_test.go; the fix pattern is deadline-based waiting"
• Bad: "Fixed a flaky test today" (not self-contained, no future value)

If a stored memory turns out to be wrong or outdated, fix it immediately: correct it in place with memory_update, or delete it with memory_forget if it should not exist. Never leave a memory you know is incorrect in place.

Keep memories atomic — one fact per call. Search works better on small, focused records than on walls of text.
