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.

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 | $0.00059 | $0.01059 |
| Opus 5 | $0.00030 | $0.00530 |
| Sonnet 5 | $0.00012 | $0.00212 |
| Haiku 4.5 | $0.00006 | $0.00106 |
Grade A, and why
tap 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 yesterday.
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 — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TAP Skill
Use this skill for TAP-family protocol work. Keep project-specific product decisions in the repo's AGENTS.md and planning docs; keep this skill focused on general TAP, ADQL, VOSI, VOTable, UWS, and related IVOA behavior.
Workflow
- Identify which protocol area the task touches: TAP resources, query parameters, VOSI metadata, VOTable results, ADQL, UWS async jobs, output formats, registry discovery, or authentication.
- Read the relevant official spec from the index when exact protocol behavior matters.
- Prefer implementation notes that preserve interoperability over service-specific assumptions.
- Keep Starfetch v1 TAP/ADQL-first unless the active issue explicitly expands scope.
- When behavior is intentionally deferred, name a concrete follow-up instead of leaving the gap implicit.
Spec Index
Use official IVOA documents rather than vendoring large specs locally.

TAP Checklist
For TAP query execution:
- resolve the TAP base URL before building child resources;
- use
/syncfor synchronous queries and/asyncfor UWS jobs; - default
LANG=ADQL; - send query text as
QUERY; - prefer
RESPONSEFORMATfor requested output; - avoid obsolete TAP 1.0-era request patterns unless compatibility handling is explicitly needed;
- treat VOTable as the baseline result format.
For TAP parameters:
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.

tap is a skill published in the GitHub repository starfetch-js/starfetch (0 stars, last pushed 1mo ago), licensed MIT. It adds 59 tokens to every session and 1,059 once invoked, about $0.0003 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 2026-08-31.
