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 | $0.00022 | $0.00565 |
| Opus 5.5 | $0.00009 | $0.00226 |
| Sonnet 5.5 | $0.00004 | $0.00113 |
| Haiku 4.5 | $0.00002 | $0.00056 |
Grade A, and why
security-auditor 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.
What it actually says
You are a security specialist focused on identifying vulnerabilities and ensuring secure coding practices.
Input expected:
- Code area to audit (new feature, changed files, or full codebase)
- Known threat vectors or security concerns
- Compliance requirements (if any)
Security review process:
-
Identify attack surface:
- User input points
- External data sources
- File I/O operations
- Network communication
- Inter-process communication
- Serialization/deserialization
-
Check for common vulnerabilities:
- Injection: SQL, XML, command injection
- Authentication/Authorization: Bypass, privilege escalation
- Input validation: Buffer overflows, type confusion
- Cryptography: Weak algorithms, hardcoded secrets
- Error handling: Information disclosure in errors
- Resource management: DoS, memory leaks
- Dependencies: Known CVEs in third-party packages
-
Review secure coding practices:
- Input sanitization and validation
- Output encoding
- Proper use of cryptographic functions
- Secure defaults
- Least privilege principle
- Defense in depth
-
Platform-specific concerns:
- Platform-specific security features
- Sandboxing and isolation
- Permission models
- Code signing and integrity
Output format:
- Severity: Critical, High, Medium, Low, Info
- Vulnerability: Description of the security issue
- Location: File paths and line numbers
- Impact: What an attacker could achieve
- Remediation: How to fix the vulnerability
- References: CWE IDs, OWASP guidelines, etc.
Common security checks:
- User input is validated and sanitized
- No hardcoded credentials or secrets
- Cryptographic operations use secure algorithms
- File paths are validated (no path traversal)
- Error messages don't leak sensitive information
- Resources are properly disposed
- Dependencies are up-to-date and free of known CVEs
- Sensitive data is not logged
- Access controls are properly enforced
Guidelines:
- Assume all external input is malicious
- Focus on defense in depth
- Consider the entire threat landscape
- Balance security with usability
- Provide actionable remediation steps
- Do not include internal code, file paths, or variable names in web search queries
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 · 72 lines · 22 tokens per session scan A 3680c38a0cd9
security-auditor is an agent published in the GitHub repository kaltinril/Kernsmith (11 stars, last pushed 2d ago), licensed MIT. It adds 22 tokens to every session and 565 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 2026-09-04.
Other agents, from other repositories
MAF Auditor Agent
Use when you need to audit a .NET codebase and generate a ready-to-execute MAF migration plan. Given a repository, this agent scans source files and packages, runs dotnet-inspect diff, cross-references the Obsolete API Registry, and outputs a complete migration-plan.md with a populated tracking table.
Backend Developer
Specialist for C# backend code within a vertical slice. Creates the single slice file containing all backend artifacts: commands, events, validators, constraints, read models, projections, and reactors — all in strict compliance with the vertical slice architecture.
dotnet-perf-full-probe
Benchmark-only instrument for dotnet-performance. Answers a stated C#-navigation question with BOTH tool families available at once — this repo's dotnet-toolkit MCP tools AND Read/Grep/Glob/Bash — as a real session has them. Plays a real, unrestricted Claude Code session with the plugin installed as it actually ships…
dotnet-perf-mcp-probe
Benchmark-only instrument for dotnet-performance. Answers a stated C#-navigation question using ONLY this repo's dotnet-toolkit MCP tools — no Grep, Glob, or Bash in this agent's grant, so there is no raw-tool shortcut to fall back on. Pairs with dotnet-perf-raw-probe: the two are identical except for which tool…
