SkillSpector: 2 findings, up to high
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 →
- high Prompt Injection · line 161 Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
- medium Excessive Agency · line 173 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00031 | $0.04695 |
| Opus 5.5 | $0.00012 | $0.01878 |
| Sonnet 5.5 | $0.00006 | $0.00939 |
| Haiku 4.5 | $0.00003 | $0.00470 |
Grade A, and why
visual-companion 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 2mo 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 — 425 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Visual Companion
This is a standalone skill. It is not tied to the broader brainstorming workflow.

Browser-based visual brainstorming companion for showing mockups, diagrams, and options.
When to Use
Decide per-question, not per-session. The test: would the user understand this better by seeing it than reading it?
Use the browser when the content itself is visual:
- UI mockups — wireframes, layouts, navigation structures, component designs
- Architecture diagrams — system components, data flow, relationship maps
- Side-by-side visual comparisons — comparing two layouts, two color schemes, two design directions
- Design polish — when the question is about look and feel, spacing, visual hierarchy
- Spatial relationships — state machines, flowcharts, entity relationships rendered as diagrams
Use the terminal when the content is text or tabular:
- Requirements and scope questions — "what does X mean?", "which features are in scope?"
- Conceptual A/B/C choices — picking between approaches described in words
- Tradeoff lists — pros/cons, comparison tables
- Technical decisions — API design, data modeling, architectural approach selection
- Clarifying questions — anything where the answer is words, not a visual preference
A question about a UI topic is not automatically a visual question. "What kind of wizard do you want?" is conceptual — use the terminal. "Which of these wizard layouts feels right?" is visual — use the browser.
How It Works
The server watches a directory for HTML files and serves the newest one to the browser. You write HTML content to screen_dir, the user sees it in their browser and can click to select options or submit small forms. Browser events are recorded to state_dir/events, state_dir/latest-event.json, and state_dir/latest-selection.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.

visual-companion is a skill published in the GitHub repository Mineru98/skills-store (13 stars, last pushed 6d ago), licensed MIT. It adds 31 tokens to every session and 4,695 once invoked, about $0.0001 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.
