chromadb

chromadb is a skill for Claude Code, Codex from EliasOulkadi/shokunin. It costs 61 tokens per session (2,080 once invoked), scanned A, original, MIT.

A tool for managing ChromaDB, a local database that stores searchable records from an AI system's past work. It supports checking storage, searching entries, listing recent records, backing up memory, deleting entries, and resetting the database.

In plain words
What is it for?
Use it to check database status, find stored decisions or files, review recent records, filter searches by project or type, and manage backups or resets.
Why use it?
It gives developers a way to inspect and maintain the stored memory instead of treating it as an inaccessible black box.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

chromadb 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 11d 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.

chromadb · Memory Storage

ChromaDB is the vector database that powers Shokunin's persistent AI memory. It stores embeddings for semantic search across sessions. Built on SQLite with an ONNX embedding model for local-first, offline-capable operation.

Workflow

Step 1: Check storage status

python ~/.shokunin/scripts/chroma-helper.py count

Output: total entries, collection count, disk size on disk, last write timestamp.

python ~/.shokunin/scripts/chroma-helper.py stats

Output: entries per type (decision, file, command, checkpoint, session_end), per project, per date range.

Step 2: Search stored entries

python ~/.shokunin/scripts/chroma-helper.py search "query text" "project-name" 10

Searches via vector similarity + BM25 keyword hybrid. Results sorted by relevance with metadata attached.

python ~/.shokunin/scripts/chroma-helper.py search "error handling" "" 20 --type decision

Filter by entry type. Leave project empty to search all projects.

Step 3: List recent entries

python ~/.shokunin/scripts/chroma-helper.py recent 10

Shows the 10 most recently inserted entries across all projects. Use for quick audit.

python ~/.shokunin/scripts/chroma-helper.py recent 50 --project myproject

Filter recent entries to a specific project.

Step 4: Backup the database

$backupDir = "$env:USERPROFILE\.shokunin\backups\chroma-$(Get-Date -Format 'yyyyMMdd-HHmmss')"
New-Item -ItemType Directory -Path $backupDir -Force | Out-Null
Compress-Archive -Path "$env:USERPROFILE\.shokunin\memory\chroma_db" -DestinationPath "$backupDir\chroma_db.zip" -Force

Also back up session logs:

Compress-Archive -Path "$env:USERPROFILE\.shokunin\memory\sessions" -DestinationPath "$backupDir\sessions.zip" -Force

Verify backup integrity:

Add-Type -AssemblyName System.IO.Compression.FileSystem
[System.IO.Compression.ZipFile]::OpenRead("$backupDir\chroma_db.zip").Entries.Count

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.
