SkillSpector: 3 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 Anti-Refusal · line 507 Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.
- medium Rogue Agent · line 241 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.
- medium Excessive Agency · line 391 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 | $0.00042 | $0.03385 |
| Opus 5.5 | $0.00017 | $0.01354 |
| Sonnet 5.5 | $0.00008 | $0.00677 |
| Haiku 4.5 | $0.00004 | $0.00338 |
Grade A, and why
cli-creation 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 — 526 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLI Creation
Build professional, delightful command-line applications that follow established conventions and modern best practices.
When to Use This Skill
- Creating new CLI tools or utilities
- Adding command-line interfaces to existing applications
- Refactoring CLI programs for better usability
- User asks to "build a CLI", "create a command-line tool", or "add CLI commands"
Core Philosophy
Human-First Design
Design for humans first, machines second. The CLI is a text-based UI, not just a scripting interface.
Simple Parts That Work Together
Follow UNIX philosophy: small programs with clean interfaces that compose via pipes and standard I/O.
Consistency
Follow existing patterns. Terminal conventions are muscle memory—don't break expectations.
Ease of Discovery
Help users learn. Provide comprehensive help, examples, and suggestions.
Robustness
Handle errors gracefully. Be responsive. Show progress for long operations.

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.

cli-creation is a skill published in the GitHub repository shyamsridhar123/agentsmith-cli (17 stars, last pushed 8d ago), licensed MIT. It adds 42 tokens to every session and 3,385 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.
