AMCS Memory Instructions
AMCS (Avalon Memory Crystal Server) is an MCP server for capturing and retrieving thoughts, memory, and project context. It is backed by Postgres with pgvector for semantic search.
You have access to an MCP memory server named AMCS.
Use AMCS as memory with two scopes:
- Project memory: preferred when the current work clearly belongs to a known project.
- Global notebook memory: allowed only when the information is not tied to any specific project.
Scope Selection Rules
- Infer the current project from the repo, current working directory, README, package or app name, and any explicit user instruction.
- Call
get_active_project. - If the active project clearly matches the current work, use it.
- If not, call
list_projectsand look for a strong match by name or explicit user intent. - If a strong match exists, call
set_active_projectand use project-scoped memory. - If no strong project match exists, you may use global notebook memory with no project.
- If multiple projects plausibly match, ask the user before reading or writing project memory.
Session Startup
At the very start of any session with AMCS:
- Call
describe_toolsto get the full list of available tools with their categories and any notes you have previously annotated. Read the notes before using a tool — they contain accumulated gotchas, workflow patterns, and field-ordering requirements you have recorded from prior sessions.
Project Session Startup
After setting the active project:
- Call
list_project_skillsto load any saved agent behaviour instructions for the project. - Call
list_project_guardrailsto load any saved agent constraints for the project. - Apply all returned skills and guardrails immediately and for the duration of the session.
- Only generate or define new skills and guardrails if none are returned. If you do create new ones, store them with
add_skilloradd_guardrailand link them to the project withadd_project_skilloradd_project_guardrailso they persist for future sessions.
Project Does Not Exist Yet
If any tool returns a project_not_found error:
- Call
create_projectwith the same name you tried to use. - Immediately retry the original tool call with that project.
Do not abandon the project scope or retry without a project. The project simply needs to be created first.
Project Memory Rules
- Use project memory for code decisions, architecture, TODOs, debugging findings, and context specific to the current repo or workstream.
- Before substantial work, always retrieve context with
get_project_contextorrecall_contextso prior decisions inform your approach. - Save durable project facts with
capture_thoughtafter completing meaningful work. - Use
save_fileorupload_filefor project assets the memory should retain, such as screenshots, PDFs, audio notes, and other documents. - If the goal is to retain the artifact itself, store the file directly instead of first reading, transcribing, or summarizing its contents.
- For binary files or files larger than 10 MB, call
upload_filewithcontent_path(absolute server-side path) first to get anamcs://files/{id}URI, then pass that URI tosave_fileascontent_urito link it to a thought. This avoids base64 encoding entirely. - For small files (≤10 MB) where a server path is not available, use
save_fileorupload_filedirectly withcontent_base64. - Link files to a specific memory with
thought_idwhen the file belongs to one thought, or to the project withprojectwhen the file is broader project context. - Use
list_filesto browse project files or thought-linked files before asking the user to resend something that may already be stored. - Use
load_filewhen you need the actual stored file contents back. The result includes bothcontent_base64and an embedded MCP binary resource atamcs://files/{id}— prefer the embedded resource when your client supports it. - You can also read a stored file's raw binary content directly via MCP resources using the URI
amcs://files/{id}without callingload_file. - Stored files and attachment metadata must not be sent to the metadata extraction client.
- Do not attach memory to the wrong project.
Global Notebook Rules
- Use global memory only for information that is genuinely cross-project or not project-bound.
- Examples: user preferences, stable personal workflows, reusable conventions, general background facts, and long-lived non-project notes.
- If information might later be confused as project-specific, prefer asking or keep it out of memory.
Memory Hygiene
- Save only durable, useful information.
- Do not save secrets, raw logs, or transient noise.
- Prefer concise summaries.
- Prefer linking a file to a thought plus a concise thought summary instead of storing opaque binary artifacts without context.
- Do not read a file just to make it storable; store the file directly and read it only when the file contents are needed for reasoning.
- Do not base64-encode a file to pass it to
save_fileif anamcs://files/{id}URI is already available from a priorupload_fileor HTTP upload. - When saving, choose the narrowest correct scope: project if project-specific, global if not.
Tool Annotations
As you learn non-obvious behaviours, gotchas, or workflow patterns for individual tools, persist them with annotate_tool:
{ "tool_name": "capture_thought", "notes": "Always pass project explicitly — session state is unreliable in this client." }
Notes are returned by describe_tools in future sessions. Annotate whenever you discover something worth remembering: a required field combination, a parameter that behaves unexpectedly, or a preferred call sequence. Pass an empty string to clear a note.
Skills and Guardrails
- Skills are reusable agent behaviour instructions (e.g. output formatting rules, reasoning strategies, workflow conventions).
- Guardrails are agent constraints and safety rules (e.g. never delete without confirmation, do not expose secrets). Each guardrail has a severity:
low,medium,high, orcritical. - Use
add_skill/add_guardrailto create new entries,list_skills/list_guardrailsto browse the full library, andremove_skill/remove_guardrailto delete entries. - Use
add_project_skill/add_project_guardrailto attach entries to the current project, andremove_project_skill/remove_project_guardrailto detach them. - Always load project skills and guardrails at session start before generating new ones — see Project Session Startup above.
Short Operational Form
At the start of every session, call describe_tools to read the full tool list and any accumulated usage notes. Use AMCS memory in project scope when the current work matches a known project; if no clear project matches, global notebook memory is allowed for non-project-specific information. At the start of every project session call list_project_skills and list_project_guardrails and apply what is returned; only create new skills or guardrails if none exist. If your MCP client does not preserve sessions across calls, pass project explicitly instead of relying on set_active_project. Store durable notes with capture_thought. For binary files or files larger than 10 MB, call upload_file with content_path to stage the file and get an amcs://files/{id} URI, then pass that URI to save_file as content_uri to link it to a thought. For small files, use save_file or upload_file with content_base64 directly. Browse stored files with list_files, and load them with load_file only when their contents are needed. Stored files can also be read as raw binary via MCP resources at amcs://files/{id}. Never store project-specific memory globally when a matching project exists, and never store memory in the wrong project. If project matching is ambiguous, ask the user. If a tool returns project_not_found, call create_project with that name and retry — never drop the project scope. Whenever you discover a non-obvious tool behaviour, gotcha, or workflow pattern, record it with annotate_tool so future sessions benefit.
