Vedic Astro Skills is a toolkit of eight AI skills that calculates Vedic astrology charts from birth details and uses the verified chart data for further analysis. It supports birth-chart readings, career and relationship analysis, birth-time adjustment, compatibility readings, and Prashna question charts, with optional imports from astrology software files or images. The skills are designed for Codex, Claude Code, and other clients that read Claude Skill formats.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00169 | $0.05678 |
| Opus 5.5 | $0.00068 | $0.02271 |
| Sonnet 5.5 | $0.00034 | $0.01136 |
| Haiku 4.5 | $0.00017 | $0.00568 |
Grade A, and why
vedic-synastry 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 2mo 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 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.
