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: 8 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 Rogue Agent · line 83 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.

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 | $0.00017 | $0.00688 |
| Opus 5 | $0.00009 | $0.00344 |
| Sonnet 5 | $0.00003 | $0.00138 |
| Haiku 4.5 | $0.00002 | $0.00069 |
Grade A, and why
find-and-install 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 11d 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Find & Install Skills
Trigger
This skill activates when you detect a capability gap that a community skill might fill, the user explicitly asks to find or install a skill and a task would benefit from a specialized skill you don't currently have
Searching for Skills
Run a search using the skills CLI:
npx skills find [query]
Review the results and assess trust level before suggesting:
- 🟢 VERIFIED (1000+ installs or known orgs like
vercel-labs,anthropics,microsoft): Suggest confidently - 🟡 COMMUNITY (50–999 installs): Suggest with a note about the install count
- 🔴 UNKNOWN (<50 installs): Show but warn the user - offer to preview the SKILL.md before installing
Installing a Skill
Once the user approves (or for 🟢 VERIFIED skills when you're confident it fits):
Step 1: Install globally
npx skills add <owner/repo@skill> -g -y
This places files into ~/.claude/skills/<name>/ or ~/.agents/skills/<name>/.
Step 2: Copy into {{portalSlug}} skills directory
cp -r ~/.claude/skills/<name>/ ~/.{{portalSlug}}/skills/<name>/
The {{portalName}} file watcher will detect the new directory and create the appropriate symlinks automatically.
Step 3: Update the skills manifest
Read ~/.{{portalSlug}}/skills.json, add the new skill entry, and write it back.
The manifest format:
{
"installed": {
"<name>": {
"source": "<owner/repo@skill>",
"installedAt": "<ISO 8601 timestamp>"
}
}
}
Step 4: Apply the skill immediately
Read the newly installed ~/.{{portalSlug}}/skills/<name>/SKILL.md and follow its instructions to complete the current task.
When No Skills Are Found
If npx skills find returns no results:
- Offer to help the user directly with the task using your built-in capabilities
- Suggest creating a custom skill if this is a recurring need (use the
skill-creatorskill)
Examples
User asks to deploy to Vercel:
npx skills find "vercel deploy"
# → vercel-labs/ai-skills@vercel-deploy (🟢 VERIFIED, 5200 installs)
npx skills add vercel-labs/ai-skills@vercel-deploy -g -y
cp -r ~/.claude/skills/vercel-deploy/ ~/.{{portalSlug}}/skills/vercel-deploy/
# → update skills.json → read SKILL.md → follow deploy instructions
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.

find-and-install is a skill published in the GitHub repository hristo2612/jinn (315 stars, last pushed 4d ago), licensed MIT. It adds 17 tokens to every session and 688 once invoked, about $0.0001 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.
