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.

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 | $0.00070 | $0.02393 |
| Opus 5 | $0.00035 | $0.01196 |
| Sonnet 5 | $0.00014 | $0.00479 |
| Haiku 4.5 | $0.00007 | $0.00239 |
Grade A, and why
healthcheck 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 10d 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.
This is a copy
81% identical to healthcheck — 76 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

BuilderForceAgents Host Hardening
Overview
Assess and harden the host running BuilderForceAgents, then align it to a user-defined risk tolerance without breaking access. Use BuilderForceAgents security tooling as a first-class signal, but treat OS hardening as a separate, explicit set of steps.
Core rules
- Recommend running this skill with a state-of-the-art model (e.g., Opus 4.5, GPT 5.2+). The agent should self-check the current model and suggest switching if below that level; do not block execution.
- Require explicit approval before any state-changing action.
- Do not modify remote access settings without confirming how the user connects.
- Prefer reversible, staged changes with a rollback plan.
- Never claim BuilderForceAgents changes the host firewall, SSH, or OS updates; it does not.
- If role/identity is unknown, provide recommendations only.
- Formatting: every set of user choices must be numbered so the user can reply with a single digit.
- System-level backups are recommended; try to verify status.
Workflow (follow in order)
0) Model self-check (non-blocking)
Before starting, check the current model. If it is below state-of-the-art (e.g., Opus 4.5, GPT 5.2+), recommend switching. Do not block execution.
1) Establish context (read-only)
Try to infer 1–5 from the environment before asking. Prefer simple, non-technical questions if you need confirmation.
Determine (in order):
- OS and version (Linux/macOS/Windows), container vs host.
- Privilege level (root/admin vs user).
- Access path (local console, SSH, RDP, tailnet).
- Network exposure (public IP, reverse proxy, tunnel).
- BuilderForceAgents gateway status and bind address.
- Backup system and status (e.g., Time Machine, system images, snapshots).
- Deployment context (local mac app, headless gateway host, remote gateway, container/CI).
- Disk encryption status (FileVault/LUKS/BitLocker).
- OS automatic security updates status. Note: these are not blocking items, but are highly recommended, especially if BuilderForceAgents can access sensitive data.
- Usage mode for a personal assistant with full access (local workstation vs headless/remote vs other).
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.

healthcheck is a skill published in the GitHub repository SeanHogg/Builderforce.ai (5 stars, last pushed today), licensed MIT. It adds 70 tokens to every session and 2,393 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 81% identical to healthcheck, differing in 76 lines, and is treated as a copy.
