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: 1 finding, 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 →
- medium Excessive Agency · line 38 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00029 | $0.00423 |
| Opus 5 | $0.00015 | $0.00211 |
| Sonnet 5 | $0.00006 | $0.00085 |
| Haiku 4.5 | $0.00003 | $0.00042 |
Grade A, and why
health-welfare-open-data 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.
What it actually says
TEHIK Seasonal COVID-19 Open Data
Access
- OpenAPI document and API root:
https://rest-avaandmed.tehik.ee/covid19/ - Swagger UI:
https://rest-avaandmed.tehik.ee/covid19/swagger/ - No authentication is required.
Datasets
opendata_covid19_hospitalization: weekly hospitalization counts by age group and bed profile.opendata_covid19_riskgroup_vaccination_season_location_agegroup: seasonal risk-group population and vaccination counts by date, county, and age group.metadata_odata: field/table descriptions, including historical schema metadata.
Query
Use PostgREST URL parameters such as select, order, limit, offset, and column filters (eq., gte., lte., in.(...)). Example:
GET https://rest-avaandmed.tehik.ee/covid19/opendata_covid19_hospitalization?Valid=eq.true&order=StatisticsWeek.desc&limit=100
Request JSON by default or text/csv with the Accept header.
Return
Preserve source endpoint, query, retrieval time, statistics date/week, season, geography/EHAK code, age group or bed profile, population/count fields, Valid, and ModifiedAt.
Limits
- These are seasonal COVID-19 aggregates, not a general health/welfare catalog and not individual records.
- Filter to
Valid=eq.trueunless invalidated revisions are explicitly needed. - A row with null dimensions may be a total; do not combine it with detailed rows without checking aggregation level.
Verify
Use the root OpenAPI document as the current schema, require the documented field set, and check Valid plus ModifiedAt before analysis.
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.

health-welfare-open-data is a skill published in the GitHub repository taivop/marketplace (17 stars, last pushed 12d ago), licensed MIT. It adds 29 tokens to every session and 423 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.
