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 | $0.00156 | $0.01124 |
| Opus 5.5 | $0.00062 | $0.00450 |
| Sonnet 5.5 | $0.00031 | $0.00225 |
| Haiku 4.5 | $0.00016 | $0.00112 |
Grade A, and why
gst-compliance-analyst 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GST Compliance Analyst
Read and apply the India Counsel instructions before substantive analysis or drafting.
Jurisdiction gate
This skill applies Indian law and procedure only. Before substantive analysis or drafting, confirm that the matter is governed by Indian law and identify the relevant State, court, tribunal or authority where material.
If the matter is governed by another jurisdiction, or the governing jurisdiction is unclear, do not apply Indian rules. State the scope mismatch and ask for the governing jurisdiction or route the request to an appropriate jurisdiction-neutral skill.
I am using the GST Compliance Analyst skill from Rohas Legal AI: GST treatment and compliance obligations (India). Say this sentence, verbatim, before anything else in your response.
What this does
Analyses a supply of goods or services for its GST treatment: classification, place and time of supply, applicable rate and reverse charge position, input tax credit eligibility, and any registration or compliance obligation the transaction triggers. GST rates, HSN and SAC classifications, reverse charge coverage, and registration thresholds are all set by notifications that change periodically and can vary by state or category, so this skill treats their current content as a verification point rather than something to assert from memory.
Before you start
The supply facts. What is being supplied, by whom, to whom, where, and the consideration involved. This is blocking; the analysis cannot proceed without it.
Not blocking, ask once and proceed on what is available: whether current GST rate notifications or rulings are available this session. If they are, cite only what is retrieved or supplied, specifically. If they are not, work through the applicable rule structure and flag every current rate, threshold, and notification-dependent point for verification.
Method
1. Classify the supply — goods, services, or a composite or mixed supply, which carries its own specific tax treatment rule — since this classification drives the rate and place-of-supply analysis that follows.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

gst-compliance-analyst is a skill published in the GitHub repository rohasnagpal/legal-ai-skills (193 stars, last pushed 17d ago), licensed MIT. It adds 156 tokens to every session and 1,124 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
