qdrant-session-memory

qdrant-session-memory is a skill for Claude Code, Codex from tolgakisaogullari/SumelaOS. It costs 39 tokens per session (1,697 once invoked), scanned A, original, MIT.

A local search tool for recalling decisions and context from earlier coding-agent sessions. It uses semantic search, which finds related meaning rather than only matching exact words.

In plain words
What is it for?
Use it before starting work, when encountering a previously discussed service or concept, or before making an architectural decision.
Why use it?
It reduces the need to repeat past explanations and helps the agent avoid revisiting decisions already made. Queries use a local Qdrant database, a system for storing and searching similar text.

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

qdrant-session-memory 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 10d ago.

The scan reads SKILL.md. This mod also ships 9 executable files (scripts/delete-from-qdrant.py, scripts/ingest-code-to-qdrant.py, scripts/ingest-wiki-to-qdrant.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Tier-1: Qdrant Session Memory

Important: No API Key Required for Queries

All query operations read from the local Qdrant database via query-qdrant.py. They are purely local — no external API calls, no cost. API keys are only needed for embedding generation via Ollama (which runs locally).

Proactive Usage (Silent)

The agent should query Qdrant without waiting for the user to ask in these scenarios:

Before Starting a Task

When the user assigns a new task, check if similar work was done before:

python .sumela/memory-plugins/qdrant-session-memory/scripts/query-qdrant.py "<task description>" --limit 3
  • If top score ≥ 0.5: read the matching session summary for context, lessons learned, and decisions made
  • If score < 0.5: skip — no relevant past context

When Encountering an Entity or Concept

When the task involves an entity, service, or concept that might have been discussed before:

python .sumela/memory-plugins/qdrant-session-memory/scripts/query-qdrant.py "<entity name> <context>" --limit 3

Example: Task mentions "CommentService" → query "CommentService design decisions"

When Making Architectural Decisions

Before proposing an architecture or design choice, check if similar decisions were made:

python .sumela/memory-plugins/qdrant-session-memory/scripts/query-qdrant.py "<decision topic>" --limit 3

Example: "caching strategy" → check if caching was discussed before

When Debugging

Before diving into a bug, check if similar issues were encountered:

python .sumela/memory-plugins/qdrant-session-memory/scripts/query-qdrant.py "<bug description or error message>" --limit 3

When a File is Mentioned

When the task involves a specific file that might have history:

python .sumela/memory-plugins/qdrant-session-memory/scripts/query-qdrant.py "<filename> changes" --limit 3

RULE: This is SILENT — do not announce "I'm checking past sessions via Qdrant" unless the user explicitly asks. Just query, read relevant context, and incorporate into your analysis.

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.
