Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 42 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.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00061 | $0.02080 |
| Opus 5 | $0.00030 | $0.01040 |
| Sonnet 5 | $0.00012 | $0.00416 |
| Haiku 4.5 | $0.00006 | $0.00208 |
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.
How it starts
The opening of the file, as written. The whole thing — 226 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.
- 11d ago First seen · 226 lines · 61 tokens per session scan A 0c71571b3192
chromadb is a skill published in the GitHub repository EliasOulkadi/shokunin (113 stars, last pushed 1mo ago), licensed MIT. It adds 61 tokens to every session and 2,080 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
