About the project

AIBAST Agents Library is a collection of industry-focused AI agent templates accompanied by a local server that connects agents to GitHub Copilot for language-model inference. It helps developers create and run tool-using agents and isolated project environments, with an optional cloud-backed path for persistent memory. The catalogue entries provide the repository's agents, skills, commands, hooks, and instructions.

Token cost

What 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.

Security

Grade A, and why

synthetic-permit-fee-estimate 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 9d 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.

What it actually says

Synthetic permit fee estimate

Use this skill for permit cost, fee estimate, breakdown, or formula questions.

Fixed formula

For every category: amount = base + (valuation / 1000) × rate, rounded to cents.

Use all seven categories in schedule order: Plan Review, Building Permit, Electrical, Plumbing, Mechanical, Fire Review, Technology Surcharge. Their bases total $850 and rates total $19.25 per $1,000.

Precomputed totals

  • BP-2025-0101: $81,700.00
  • BP-2025-0102: $4,411.25
  • BP-2025-0103: $7,010.00
  • BP-2025-0104: $131,750.00
  • BP-2025-0105: $81,700.00
  • BP-2025-0106: $11,245.00

Output

Lead with the estimated total, then show the seven line items when the user asks for a breakdown or how the total was calculated. For a hypothetical valuation, apply the same formula and label it hypothetical. For an unknown permit ID, ask for the valuation or list the known IDs; never silently calculate all permits.

Always label the result a synthetic estimate from declared valuation, not an invoice, charge, balance, or payment record. Never waive or alter a fee.

Changes

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.
