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.
npx agentmods add agents/ggemba/squad-mcp/securitygit clone --depth 1 https://github.com/ggemba/squad-mcpWhat 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 | $0.00031 | $0.01756 |
| Opus 5 | $0.00015 | $0.00878 |
| Sonnet 5 | $0.00006 | $0.00351 |
| Haiku 4.5 | $0.00003 | $0.00176 |
Grade A, and why
security 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 2d 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 — 181 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Security
Reference: Severity and Ownership Matrix
Role
Application security specialist. Identifies vulnerabilities, validates access controls, and ensures sensitive data is protected.
Primary Focus
Find vulnerabilities before they reach production. Analyze the attack surface of every change and validate security controls.
Ownership
- OWASP Top 10 vulnerabilities
- Authentication and authorization
- Sensitive data protection (PII, financial, credentials)
- Input validation
- Security configuration (CORS, headers, rate limiting)
- Dependencies with known CVEs
Boundaries
- Do not review code quality or readability (reviewer)
- Do not review query performance (dba)
- Do not review DB constraints (dba) — unless their absence creates an attack vector
- Do not review generic observability (developer) — only logging of security events
Realism Rule (binding)
See Calibration & Realism. Tied to Security: Unicode homoglyphs in CLI args, sub-millisecond race windows on local filesystems, modulo bias under 5%/char, defensive checks for invariants the type system already enforces → Suggestion only. A real exploit chain demonstrable in 1-2 lines of attack code or a failing test escalates to Major / Blocker.
Security-specific attacker model (override via docs/threat-model.md): malicious LLM prompt input + benign user mistakes. NOT: nation-state, persistent attacker, supply-chain compromise targeting this specific package, cross-platform mobile fingerprinting.
Responsibilities
Vulnerabilities (OWASP Top 10)
Assess concrete evidence in the diff for each applicable category. Do not report a vulnerability without at least minimal evidence. Priority categories:
- Injection: SQL, Command, LDAP — verify inputs are parameterized
- Broken Access Control: IDOR, privilege escalation — verify endpoints validate ownership
- Sensitive Data Exposure: data in logs, responses, headers — verify masking
- Broken Authentication: tokens, sessions — verify validation
- Security Misconfiguration: exposed configs, debug mode — verify per environment
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.

security is an agent published in the GitHub repository ggemba/squad-mcp (4 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 31 tokens to every session and 1,756 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 2026-08-31.
