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 Data Exfiltration · line 120 Code scans file system directories looking for sensitive files. This could be reconnaissance for credential theft.Fix: Remove unnecessary filesystem scanning. If file access is needed, use explicit, scoped paths. Avoid reading ~/.ssh, ~/.aws, or credential directories.
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 | $0.00052 | $0.01035 |
| Opus 5.5 | $0.00021 | $0.00414 |
| Sonnet 5.5 | $0.00010 | $0.00207 |
| Haiku 4.5 | $0.00005 | $0.00103 |
Grade A, and why
maintainer-bar 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 1mo 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.

MaintainerBar — Maintainer Menu Bar Skill
Overview
MaintainerBar is a native macOS SwiftUI menu bar app for GitHub repo maintenance. It's backed by ghcrawl (local SQLite + OpenAI embeddings) for issue/PR clustering and semantic search.
Repo: ~/Documents/GitHub/OpenKnots/MaintainerBar
Stack: SwiftUI (Swift Package Manager), macOS 14+
Backend: ghcrawl CLI (JSON mode) + GitHub API via gh
Host: MB Black (macOS node)
Prerequisites
- ghcrawl installed:
~/.nvm/versions/node/v24.13.0/bin/ghcrawl - Wrapper:
~/.local/bin/ghcrawl-op(injects GitHub token viagh auth+ OpenAI key via 1Password) - Xcode 26+ / Swift 6.0+
ghCLI authenticatedopCLI (1Password) for OpenAI key
Build & Run
# Build
cd ~/Documents/GitHub/OpenKnots/MaintainerBar
swift build
# Run (debug)
swift run MaintainerBar
# Run built binary directly
.build/debug/MaintainerBar
ghcrawl Operations (via wrapper)
All ghcrawl commands should use the ghcrawl-op wrapper or inject env vars:
# Refresh a repo (sync + embed + cluster)
~/.local/bin/ghcrawl-op refresh openclaw/openclaw
# List clusters (JSON)
~/.local/bin/ghcrawl-op clusters openclaw/openclaw --min-size 2 --limit 30 --json
# Semantic search
~/.local/bin/ghcrawl-op search openclaw/openclaw --query "download stalls" --json
# Cluster detail
~/.local/bin/ghcrawl-op cluster-detail openclaw/openclaw --id 123 --json
# Specific threads
~/.local/bin/ghcrawl-op threads openclaw/openclaw --numbers 42,43,44 --json
# Author's open issues
~/.local/bin/ghcrawl-op author openclaw/openclaw --login someone --json
# Health check
~/.local/bin/ghcrawl-op doctor --json

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.
- 1mo ago First seen · 132 lines · 52 tokens per session scan A 1f3bb5d96eee
maintainer-bar is a skill published in the GitHub repository OpenCoven/coven (73 stars, last pushed today), licensed MIT. It adds 52 tokens to every session and 1,035 once invoked, about $0.0002 per session on Opus 5.5. 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.
