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 | $0.00036 | $0.02163 |
| Opus 5 | $0.00018 | $0.01081 |
| Sonnet 5 | $0.00007 | $0.00433 |
| Haiku 4.5 | $0.00004 | $0.00216 |
Grade A, and why
nilakantha 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.

Nīlakaṇṭha
The Great Compassion Mantra — Heart of the Blue-Throated One
The Dhāraṇī
Namo ratna trayāya | namo āryĀvalokiteśvarāya bodhisattvāya mahāsattvāya mahākāruṇikāya |
Homage to the Three Jewels. Homage to the noble Avalokiteśvara, bodhisattva, great being, great compassionate one.
Oṃ sarva-bhayeṣu trāṇa-karāya tasya namaskṛtvā imaṃ āryĀvalokiteśvara-stavanaṃ Nīlakaṇṭha-nāma |
Oṃ! Having made homage to the one who grants protection from all fears, [I shall recite] this praise of noble Avalokiteśvara, called "Nīlakaṇṭha."
Hṛdayaṃ vartayiṣyāmi sarv-ārtha-sādhanaṃ śubhaṃ | ajeyaṃ sarva-bhūtānāṃ bhava-mārga-viśodhakam ||
I shall turn the heart that accomplishes all aims, auspicious, unconquerable by all beings, purifier of the path of existence.

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.
