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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 43 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
- medium Rogue Agent · line 184 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00136 | $0.02572 |
| Opus 5 | $0.00068 | $0.01286 |
| Sonnet 5 | $0.00027 | $0.00514 |
| Haiku 4.5 | $0.00014 | $0.00257 |
Grade A, and why
nyxid-service-skill-authoring 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 12d 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 — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.
NyxID service skill authoring (via Ornn)
You are an agent facing a NyxID proxy service you do not know how to call:
the service publishes no OpenAPI spec, nyxid catalog endpoints <slug>
returns nothing, and the only tool available is the generic proxy
request (path + method + body). Do not guess endpoint paths from
training memory — that is how hallucinated calls happen. Follow this
flow instead: find an existing skill on Ornn, or author one from a
verifiable source.
Prerequisite: the ornn-agent-manual-cli skill (the Ornn API contract).
If it is not already in your context or local skills directory, pull it
first:
nyxid proxy request ornn-api "/api/v1/skills/ornn-agent-manual-cli/json" \
--method GET --output json
All Ornn calls below assume that manual is loaded; it defines authentication, response shapes, and error handling.
No shell? Every step works over plain HTTP
Some agent runtimes cannot execute a CLI but can make HTTP requests. Every
nyxid command in this skill has a direct REST equivalent against the
NyxID API (base URL below is the deployment you authenticate against,
e.g. https://nyx-api.chrono-ai.fun):
- Auth: send
Authorization: Bearer <token>on every request — a NyxID agent API key (nyxid_ag_...) or a user access token. Ask the user for a key if you have none; never scrape one from disk. - Ornn calls:
nyxid proxy request ornn-api "<path>" --method Mis exactlyM {BASE}/api/v1/proxy/s/ornn-api<path>— same path, same body, same JSON response. This holds for every Ornn endpoint in this skill and in the Ornn manual. - Service inventory (
nyxid service list):GET {BASE}/api/v1/keys— the authoritative connected-services view. - Catalog metadata (
nyxid catalog show <slug>):GET {BASE}/api/v1/catalog/{slug}; typed operations (nyxid catalog endpoints <slug>):GET {BASE}/api/v1/catalog/{slug}/endpoints. - Mount a spec / set skills (
nyxid service update ...):PUT {BASE}/api/v1/keys/{id}with the exact ID returned by the keys inventory and a JSON body — e.g.{"openapi_spec_url": "https://..."}(empty string clears) or{"recommended_skills": ["name"]}(empty list clears). The endpoint document alone can also be updated viaPUT {BASE}/api/v1/endpoints/{endpoint_id}with the same fields. - Update account-owned routing or identity settings:
resolve the exact UserService ID from
GET {BASE}/api/v1/keys, then usePUT {BASE}/api/v1/user-services/{user_service_id}— for example,{"forward_access_token": true}. A catalog service ID is a different identity and must never be used here. ReadGET {BASE}/api/v1/keysafterward and verify the same UserService ID. Platform-wide catalog recovery is the separate admin-onlyPOST {BASE}/api/v1/services/{catalog_service_id}/resync-identityAPI. - Call the target service through the proxy
(
nyxid proxy request <slug> ...):M {BASE}/api/v1/proxy/s/{slug}/<path>— NyxID injects the stored credential; never send the downstream credential yourself.
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.
- 12d ago First seen · 213 lines · 136 tokens per session scan A 36a54e1edcd1
nyxid-service-skill-authoring is a skill published in the GitHub repository ChronoAIProject/NyxID (36 stars, last pushed yesterday), licensed Apache-2.0. It adds 136 tokens to every session and 2,572 once invoked, about $0.0007 per session on Opus 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 2026-08-30.
