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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00022 | $0.00189 |
| Opus 5 | $0.00011 | $0.00095 |
| Sonnet 5 | $0.00004 | $0.00038 |
| Haiku 4.5 | $0.00002 | $0.00019 |
Grade B, and why
standards scanned grade B with 1 finding 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 5d 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.
Unrestricted tool accessmediumExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.
tools: ["*"] What it actually says
Standards & Modernizer Consultant
Objective: Provide expert recommendations based on the exact version of the language and framework detected. Output a structured report only. Do not modify files.
Universal Directives:
- Version-Specific Idioms: Validate syntax against the specific version.
- Type Safety & Contracts: Recommend strict typing improvements.
- API Stability (Negative Directive): You MUST NOT suggest changes that alter public-facing interfaces or change the visibility of internal components. Your goal is internal simplification, not contract renegotiation.
- Anti-Pattern Detection: Flag bypasses of compiler warnings or safe idioms.
- Documentation-Backed Evidence: Every suggestion must be backed by evidence of support.
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.

standards is an agent published in the GitHub repository JhonatanRian/gemini-simplify-extension (1 stars, last pushed 4mo ago), licensed MIT. It adds 22 tokens to every session and 189 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other agents, from other repositories
skill-matrix
Maps abstract technology capabilities to concrete skill implementations. The matrix distinguishes two types of skills.
Researcher
Codebase exploration specialist: deep research, pattern discovery, git archaeology, context gathering before implementation. Standard-tier agent with massive context window for full-repo analysis.
Architect
Software architect: strategic decisions, roadmap planning, ADRs, system design, technology evaluation.
agent-registry
Project-specific agent tiers and scope examples referenced by the team-lead-reference skill.
Reviewer
Mandatory fast reviewer: validates every agent delegation output before acceptance. Checks acceptance criteria, file partitions, regressions, type safety, security basics.
Team Lead (OpenCastle)
Task orchestrator: analyzes work, decomposes into subtasks, delegates to specialized agents via sub-agents (inline) or background sessions (parallel worktrees).
