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 5.1 | $0.00488 | $0.00488 |
| Opus 5 | $0.00244 | $0.00244 |
| Sonnet 5 | $0.00098 | $0.00098 |
| Haiku 4.5 | $0.00049 | $0.00049 |
Grade C, and why
agent-skills AGENTS.md scanned grade C with 2 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 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.

Workflow
| Situation | Chain |
|---|---|
| New repo | get_project_context (topic identity / run) → optional explain_architecture |
| Feature / fix | find_code → read_code → check_test after edits |
| How it wires | explain_architecture |
| Before install | check_package (task=check, then upgrade / security if needed) |
| Live URL | audit_headers |
| Remember facts | project_memory |
| Stuck | keep_thinking with lastActions |
| Terminal / free layout | CLI: zephex deep --json · structure --agent · overview · test / check test failures |
Pass absolute path (or github:owner/repo) on every repo tool. Prefer MCP when connected. Call check_package before install suggestions. If they named Zephex, call a tool (or CLI command) before answering about their code.

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.

agent-skills AGENTS.md is an instructions file published in the GitHub repository zephexMCP/agent-skills (5 stars, last pushed 23d ago), licensed MIT. It adds 488 tokens to every session, about $0.0024 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
