SkillSpector: 3 findings, up to medium
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 →

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 | $0.00095 | $0.01679 |
| Opus 5 | $0.00048 | $0.00839 |
| Sonnet 5 | $0.00019 | $0.00336 |
| Haiku 4.5 | $0.00010 | $0.00168 |
Grade A, and why
add-customer-to-user-list 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.
How it starts
The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Single source of truth: maintain this skill under
.agents/skills/add-customer-to-user-list/only. Claude and Cursor load projected copies under.claude/skills/add-customer-to-user-listand.cursor/skills/add-customer-to-user-list.
Add a customer to the users list
Adds or updates one row in the public adopters table on /users.
Do not write a customer story in this skill. If the user wants a full
/users/<slug> case study, use
customer-story-setup first, then come
back here to link it.
Canonical file
| What | Where |
|---|---|
| Adopters table (source of truth) | components-mdx/adopters-table.mdx |
| Rendered on | /users (content/customers/index.mdx) and the handbook customers chapter |
The handbook imports the same table (<AdoptersTable />). Editing the MDX
file updates both pages. Do not duplicate the table elsewhere.
Before writing any file
Collect what you can from the request. Ask only for what is still missing:
- Company name — public marketing name
- Company website — used in the Company column
- Use case — optional; write one if a user story or external link exists
- External reference URL — optional public source (blog, job post, DPA, talk)
Then always check for a user story. Do not skip this step.
Always check: is there a user story?
Search the working tree and origin/main (this branch may be behind):
content/customers/meta.json→pages(skip"index")content/customers/*.mdx— match company name, legal name, or obvious slug variants (hugging-facevshuggingface,merckgroupvsmerck)- Frontmatter

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.

add-customer-to-user-list is a skill published in the GitHub repository langfuse/langfuse-docs (240 stars, last pushed today), licensed MIT. It adds 95 tokens to every session and 1,679 once invoked, about $0.0005 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.
