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 5.1 | $0.00038 | $0.00345 |
| Opus 5 | $0.00019 | $0.00172 |
| Sonnet 5 | $0.00008 | $0.00069 |
| Haiku 4.5 | $0.00004 | $0.00034 |
Grade A, and why
go-data-architecture 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 4d 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
Go Data Architecture
Every datum answers to one authority: the single store and writer whose acceptance makes it true, from which every copy, projection, and cache admits being derived.
authority -> identity and tenancy -> write invariant -> evolution and backfill -> derived surfaces -> retention -> proof
A derived surface that cannot name its source, lag, and repair path is a second authority waiting to disagree, and retention is a designed lifecycle stage with an owner rather than a response to disk pressure.
For a delegated Decision or Review, or when the active artifact requires its
result interface, load the
shared specialist contract.
From every changed writer or durable schema through each reader, projection,
export, cache, repair, and retention path, build AuthorityRecord{datum, identity, writer, invariant, derived_surfaces, lag, repair, evolution, retention, proof}. A derived surface that cannot name its source, lag, and
repair path is a competing authority. Complete when every affected datum has
one authority and every derived surface and lifecycle stage has a disposition.
postgres-schema-design
owns relational modeling and expand-and-contract mechanics. Load the decision
selector only when this repository's current migration,
publication, derived-surface, or retention policy changes the decision.
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.

go-data-architecture is a skill published in the GitHub repository Dankosik/go-service-template-rest (7 stars, last pushed 3d ago), licensed MIT. It adds 38 tokens to every session and 345 once invoked, about $0.0002 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.

sq
Guides use of the sq CLI to query SQL databases and tabular files with SLQ (sq's jq-like query language) or native SQL, manage sources, choose output formats, and run inspect, diff, and table commands. Use when the user mentions sq, SLQ, wrangling CSV/Excel/JSON/DB data, cross-source joins, or command-line data…
pi-loop-forensics
Diagnose pi-go agent loops and degenerate turns — "agent loop aborted", runaway thinking with no tool calls, repeated phrases. Discriminates genuine model repetition collapse from a race, a tool-parse failure, or a too-low guard, and A/B replays a seed session across providers.
nightly-session-watch
Nightly sweep of the last 24h of pi-go sessions — anomalous runs, loop aborts, tool error rates, token waste, real prompt-token spend, and whether the observation and palace pipelines are still recording. Triages each finding to the specialist skill that diagnoses it. Use for an unattended daily health check, or on…
