Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00036 | $0.00351 |
| Opus 5 | $0.00018 | $0.00176 |
| Sonnet 5 | $0.00007 | $0.00070 |
| Haiku 4.5 | $0.00004 | $0.00035 |
Grade B, and why
vanguard-frontier-agentic-install 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 12d 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.

Vanguard Frontier Agentic Codex Install
Use this skill when the user wants the Vanguard Frontier Agentic marketplace content installed into Codex as real user-level agents and skills.
Reliable two-stage install
Run from any directory:
codex plugin marketplace add VincentChuWaiChow/vanguard-frontier-agentic
npx --yes -p @raishin/vanguard-frontier-agentic \
vfa-export-agents --platform codex --all --repo "$HOME" --force
If working from a local checkout of the repository, prefer the local exporter so unpublished branch changes are used:
node scripts/export-marketplace-agents.mjs --platform codex --all --repo "$HOME" --force
Verify
find "$HOME/.codex/agents" -maxdepth 1 -name '*.toml' | wc -l
find "$HOME/.codex/skills" -mindepth 1 -maxdepth 1 -type d | wc -l
Expected for this release: all Codex-capable VFA agents are installed under $HOME/.codex/agents, and companion skills are installed under $HOME/.codex/skills.
Important limitation
codex plugin marketplace add installs/tracks the marketplace source. It does not, by itself, prove that Codex installed the plugin cache or exported repo-level agent TOML files. The exporter is the deterministic second stage for agents and companion skills.
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.
