Memorise

Recommended model tier: balanced (sonnet) - this skill performs straightforward operations

Capture important information for future sessions by storing it in the aide memory database.

How to Store

Use the ./.aide/bin/aide memory add CLI command via Bash:

./.aide/bin/aide memory add --category=<category> --tags=<comma,separated,tags> "<content>"

Binary location: The aide binary is at .aide/bin/aide. If it's on your $PATH, you can use aide directly.

Categories

• learning - Something discovered about the codebase or tools
• decision - An architectural or design choice made
• session - Summary of a work session
• pattern - A reusable approach or pattern identified
• gotcha - A pitfall or issue to avoid in future
• abandoned - An approach that was tried and abandoned (see Abandoned Approaches below)

When to Use

• End of a significant task or session
• After discovering something important about the codebase
• When a decision is made that should persist
• After solving a tricky problem (capture the solution)
• When user shares a preference or important information

Examples

Simple preference (global - injected at session start)

./.aide/bin/aide memory add --category=learning --tags=preferences,colour,scope:global,source:user "User's favourite colour is blue"

Technical learning (project-specific, verified)

./.aide/bin/aide memory add --category=learning --tags=testing,vitest,project:myapp,session:abc12345,source:discovered,verified:true "Vitest requires .js extensions for ESM imports even for .ts files. Configure moduleResolution: NodeNext in tsconfig."

Session summary

./.aide/bin/aide memory add --category=session --tags=auth,api,project:myapp,session:abc12345,source:discovered "Implemented JWT auth with 15min access tokens, 7day refresh tokens in httpOnly cookies. Files: src/auth/jwt.ts, src/middleware/auth.ts, src/routes/auth.ts"

Gotcha (global - applies everywhere)

./.aide/bin/aide memory add --category=gotcha --tags=hooks,claude-code,scope:global,source:discovered,verified:true "Hooks must not write to stderr - Claude Code interprets any stderr as error. Debug logging must go to files only."

Unverified external claim

./.aide/bin/aide memory add --category=learning --tags=api,stripe,project:myapp,source:user,verified:false "Stripe webhook signatures use HMAC-SHA256 with the whsec_ prefix."

Instructions

When the user invokes /aide:memorise <something>:

1. Parse what they want to remember
2. Verify factual claims before storing (see Verification Before Storage below)
3. Determine the scope:
   • User preference (colour, style, etc.) → add scope:global
   • Project-specific learning → add project:<project-name>,session:${AIDE_SESSION_ID}
   • Session summary → add project:<project-name>,session:${AIDE_SESSION_ID}
4. Choose appropriate category and descriptive tags
5. Add provenance tags (see Provenance Tags below)
6. Format the content concisely but completely
7. Call ./.aide/bin/aide memory add via Bash to store it
8. Verify success - check exit code is 0 and output contains the memory ID
9. Confirm what was stored, including verification outcome

Keep content concise - aim for 1-3 sentences unless it's a complex session summary.

Verification Before Storage (Anti-Poison)

Memories persist across sessions and influence future behaviour. Storing incorrect information is worse than storing nothing — it creates compounding errors. Before storing any memory, verify its claims.

What to Verify

What Does NOT Need Verification

• User preferences — The user is the authority ("I prefer tabs over spaces")
• Session summaries — Recap of what just happened in the current session
• Opinions/decisions — Architectural choices made by the user ("We chose Postgres")
• External facts — Things not checkable against the codebase ("React 19 uses...")

Verification Workflow

Is it a codebase claim (file, function, path, command, behaviour)?
├── No → Store directly with source:user or source:stated
└── Yes → Can you verify it right now?
          ├── Yes → Verify it
          │         ├── Correct → Store with verified:true
          │         └── Wrong → Inform user, do NOT store. Offer corrected version.
          └── No (e.g., external service, runtime behaviour)
                    → Store with verified:false, note unverified

Verification Rules

1. NEVER store a codebase claim without checking — If the user says "the auth middleware is in src/middleware/auth.ts", confirm the file exists before memorising.
2. If verification fails, do NOT store — Tell the user what you found instead and offer to store the corrected version.
3. If you cannot verify (e.g., claim about runtime behaviour, external API), store it but tag with verified:false.
4. Err on the side of not storing — A missing memory is recoverable; a wrong memory causes future errors.

Example: Verified vs Rejected

User says: "Remember that the database schema is defined in db/schema.sql"

Verification steps:

1. Check: does db/schema.sql exist? → Use Glob to search
2. If yes → Store with verified:true
3. If no → "I checked and db/schema.sql doesn't exist. I found database/migrations/ instead. Would you like me to store that instead?"

Provenance Tags

Always include provenance tags to track the origin and verification status of memories:

Provenance Rules

• Every memory MUST have exactly one source: tag
• Codebase claims MUST have a verified: tag
• User preferences and opinions do NOT need verified: tags (user is authoritative)

Failure Handling

If ./.aide/bin/aide memory add fails:

1. Check error message - common issues:
   • Database not accessible: ensure aide MCP server is running
   • Invalid category: use one of learning, decision, session, pattern, gotcha
   • Empty content: content must be non-empty
2. Retry with fixes if the issue is correctable
3. Report failure if unable to store:

   Failed to store memory: <error details>
   Please check aide MCP server status.

Verification

A successful memory add returns:

Added memory: <ULID>

You can verify by searching for the memory:

./.aide/bin/aide memory search "<key term from content>" --limit=1

Scope Tags

Use scope tags to control when memories are injected:

Tagging Rules

• User preferences (favourite colour, coding style): Always add scope:global
• Project learnings (API patterns, testing approach): Add project:<name>,session:<id>
• Session summaries: Add project:<name>,session:<id> with category=session

Get the project name from the git remote or directory name. Session ID is available as $AIDE_SESSION_ID (set by aide hooks) or $CLAUDE_SESSION_ID (Claude Code native).

Abandoned Approaches

When an approach is tried and abandoned during implementation, debugging, or design, record it as an abandoned memory. This prevents future sessions from repeating the same failed approach.

When to Record

• You try an implementation approach and it fails or is rejected
• You explore a design direction and discover it won't work
• The user explicitly abandons a direction (e.g., "let's not do it that way")
• A dependency or library is evaluated and rejected

Content Template

Use this structured format:

ABANDONED: <what was tried>
REASON: <why it was abandoned>
ALTERNATIVE: <what was done instead, or "none yet">
CONTEXT: <any useful context for future reference>

Required Tags

Example

./.aide/bin/aide memory add --category=abandoned \
  --tags=reason:performance,approach:sqlite-fts,project:aide,session:abc12345,source:discovered \
  "ABANDONED: Using SQLite FTS5 for memory search. REASON: go-sqlite3 requires CGO which breaks cross-compilation. ALTERNATIVE: Bleve full-text search (pure Go). CONTEXT: FTS5 was faster in benchmarks but CGO dependency was a non-starter for the release pipeline."

Decision Interaction

If an abandoned approach contradicts or supersedes an existing Decision (check with mcp__plugin_aide_aide__decision_list), also update the decision to reflect the change. For example, if a decision said "use SQLite FTS" and you abandoned that approach, update the decision with the new direction.

For Swarm/Multi-Agent

Add agent context to tags:

./.aide/bin/aide memory add --category=session --tags=swarm,agent:main "Overall task outcome..."
