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: 2 findings, 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 Agent Snooping · line 57 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
- medium Rogue Agent · line 89 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 | $0.00031 | $0.00768 |
| Opus 5 | $0.00015 | $0.00384 |
| Sonnet 5 | $0.00006 | $0.00154 |
| Haiku 4.5 | $0.00003 | $0.00077 |
Grade A, and why
task-master-viewer 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 12d 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 — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Task Master Viewer
Visual GUI for managing Task Master tasks.json files.
When to Use
Use when:
- User asks to "view tasks visually", "open task editor", "launch GUI", or "see tasks in browser"
- User wants to edit multiple tasks without typing commands
- User needs to reorganize task hierarchy
- CLI/MCP tools feel cumbersome
Don't use when:
- User is comfortable with CLI (
task-master list, etc.) - User wants to script or automate tasks
- Headless/server environment without browser
Quick Start
1. Check Streamlit Installation
python -c "import streamlit" 2>/dev/null && echo "✓ Installed" || pip install -U streamlit
2. Launch Application
cd .claude/skills/task-master-viewer && streamlit run app.py
Output:
Local URL: http://localhost:8501
App opens automatically in user's browser.
3. Tell User
✓ Task Master editor is open at http://localhost:8501
To stop: Close browser tab and press Ctrl+C
Technical Details
File Location: .claude/skills/task-master-viewer/app.py
Dependencies: streamlit (only requirement)
Default Path: PROJECT_ROOT/.taskmaster/tasks/tasks.json
Port: 8501 (auto-increments if busy)
Theme: Snowflake brand colors in .streamlit/config.toml
Data Format: Standard Task Master JSON with tagged task lists
Stopping the App
Foreground (default):
# User presses Ctrl+C
Kill Process:
pkill -f "streamlit run"
Background (if needed):
cd .claude/skills/task-master-viewer
nohup streamlit run app.py > /dev/null 2>&1 &
echo $! > streamlit.pid
# To stop
kill $(cat streamlit.pid)
Common Issues
| Issue | Solution |
|---|---|
| "Address already in use" | pkill -f "streamlit run" then restart |
| "Module 'streamlit' not found" | pip install streamlit |
| Wrong directory error | Must run from .claude/skills/task-master-viewer/ |
| File not found | User sets path in sidebar settings |
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 12d ago First seen · 145 lines · 31 tokens per session scan A 7b3c0d6fba4c
task-master-viewer is a skill published in the GitHub repository sfc-gh-dflippo/snowflake-dbt-demo (33 stars, last pushed 3d ago), licensed Apache-2.0. It adds 31 tokens to every session and 768 once invoked, about $0.0002 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.
