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: 5 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 54 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.

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 | $0.00051 | $0.01781 |
| Opus 5.5 | $0.00020 | $0.00712 |
| Sonnet 5.5 | $0.00010 | $0.00356 |
| Haiku 4.5 | $0.00005 | $0.00178 |
Grade A, and why
linear-graphql-skill 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.

Linear GraphQL Skill
Use this skill to run Linear GraphQL API operations through uxc.
Reuse the uxc skill guidance for discovery, schema inspection, auth lifecycle, and error recovery.
Prerequisites
uxcis installed and available inPATH.- Network access to
https://api.linear.app/graphql. - Linear API key or OAuth credentials available.
Authentication
Linear supports two authentication methods:
Option 1: Personal API Key (Recommended for development)
-
Get your API key from Linear: https://linear.app/settings/api
-
Set credential with custom Authorization header:
uxc auth credential set linear-graphql \ --auth-type api_key \ --header "Authorization:{{secret}}" \ --secret "lin_api_XXX"Or use environment variable:
export LINEAR_API_KEY="lin_api_XXX" uxc auth credential set linear-graphql \ --auth-type api_key \ --header "Authorization:{{secret}}" \ --secret-env LINEAR_API_KEY -
Bind endpoint:
uxc auth binding add \ --id linear-graphql \ --host api.linear.app \ --path-prefix /graphql \ --scheme https \ --credential linear-graphql \ --priority 100
Important (Personal API Key only): Linear API keys require Authorization: lin_api_XXX format (no Bearer prefix). The --header "Authorization:{{secret}}" configuration above is required for API key auth. For OAuth access tokens, use standard Authorization: Bearer <token> semantics (handled by the OAuth credential flow in uxc).
Credential/binding IDs in this skill use linear-graphql by convention; IDs are local aliases and can be changed if needed.
Option 2: OAuth 2.0 (For production/user-delegated access)
-
Create an OAuth app in Linear: https://linear.app/settings/api
-
Start OAuth login:
uxc auth oauth start linear-graphql \ --endpoint https://api.linear.app/graphql \ --redirect-uri http://127.0.0.1:8788/callback \ --scope read \ --scope write
What ships with it
3 files 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.
- 1mo ago First seen · 217 lines · 51 tokens per session scan A 8f3b3aaee415
linear-graphql-skill is a skill published in the GitHub repository holon-run/uxc (119 stars, last pushed 1mo ago), licensed MIT. It adds 51 tokens to every session and 1,781 once invoked, about $0.0002 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 2026-08-30.
