memoria: Instructions file for Kiro

.kiro/steering/session-lifecycle.md

session-lifecycle is an instructions file for Kiro from matrixorigin/memoria. It costs 741 tokens per session, scanned A, original, Apache-2.0.

A set of instructions for managing a conversation from start to finish. It uses stored memory at the beginning, during topic changes, and when wrapping up work.

In plain words
What is it for?
Use it to load relevant context before responding, refresh context when the task changes, and clean up or record useful information at the end of a session.
Why use it?
It reduces the chance of forgetting earlier decisions, goals, or user preferences during a long conversation. It also helps keep session-specific context separate and current.

This is matrixorigin/memoria's own configuration. It tells Kiro how to work on memoria itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything memoria configures →

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

session-lifecycle 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 4d 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.

Session Lifecycle Management

Systematic memory management across conversation phases: bootstrap, mid-session, and wrap-up.

Phase 1: Conversation Start (Bootstrap)

Before your first response, run a multi-query bootstrap to load full context:

  1. Primary query — derive from user's message: memory_retrieve(query="<semantic extraction>")
  2. Active goalsmemory_search(query="GOAL ACTIVE") (if user's message references ongoing work, a previous task, or doesn't start a clearly new topic)
  3. User profilememory_profile() (if user asks about preferences or you need style context)

Combine retrieved context into a mental model. Flag anything that looks stale (e.g., "Currently debugging X" from days ago).

session_id: If the user's tool provides a session ID, pass it to memory_retrieve and memory_store throughout the conversation. This enables episodic memory and per-session retrieval boosting.

Phase 2: Mid-Session (Active Work)

Re-retrieval triggers

Call memory_retrieve again mid-conversation when:

  • User shifts to a completely different topic
  • You need context about something not covered in the initial bootstrap
  • User references a past decision or preference you don't have loaded

Store cadence

  • Don't batch-store at the end. Store facts as they emerge — this gives each memory accurate timestamps.
  • One fact per memory_store call. Don't combine unrelated facts into one memory.

Working memory discipline (when to store as working, when to promote/purge) is defined in memory.md — follow those rules here.

Phase 3: Conversation End (Wrap-Up)

When the conversation is winding down (user says thanks, goodbye, or stops engaging):

1. Clean up working memories

memory_purge(topic="<task keyword>", reason="session complete")

Only purge working memories for tasks that are actually done. Leave active task working memories for next session.

2. Promote durable findings

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.
