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.

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 | $0.01517 |
| Opus 5.5 | $0.00007 | $0.00607 |
| Sonnet 5.5 | $0.00003 | $0.00303 |
| Haiku 4.5 | $0.00002 | $0.00152 |
Grade A, and why
go-add-migration 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 1mo 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 — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Go Add Migration
Create properly named PostgreSQL migration files for a GOB microservice following all project conventions.
Trigger Phrases
"add migration", "new migration", "criar migration", "nova migration", "create migration"
Arguments
$ARGUMENTS should specify:
- Service name (e.g.,
gob-member-service) — required - Migration type (create_table, add_column, create_index, seed, alter_table, custom) — inferred from description
- Description — what the migration does (e.g., "create notifications table", "add phone column to members", "seed default categories")
Pre-Flight Checks
Before generating files, read:
- Existing migrations —
ls services/{service}/migrations/to determine the next 3-digit sequence number - go.mod —
services/{service}/go.modto confirm the service exists and get module path - Schema name — derive from the service-to-schema mapping below
Service-to-Schema Mapping
| Service | Schema |
|---|---|
| gob-auth-service | auth |
| gob-member-service | member |
| gob-lodge-service | lodge |
| gob-session-service | session |
| gob-process-service | process |
| gob-election-service | election |
| gob-bulletin-service | bulletin |
| gob-partnership-service | partnership |
| gob-audit-service | audit |
| gob-report-service | report |
| gob-notification-service | notification |
| gob-financial-service | financial |
| gob-assistance-service | assistance |
| gob-whatsapp-service | |
| gob-migration-service | migration |
If the service is not listed, extract the schema name from the service name by removing the gob- prefix and -service suffix.
Migration Numbering
- List all files in
services/{service}/migrations/ - Find the highest existing number prefix (e.g.,
012_xxx.up.sql→ 12) - The new migration number is
highest + 1, zero-padded to 3 digits (e.g.,013) - Generate both
.up.sqland.down.sqlfiles
File naming: {NNN}_{description_in_snake_case}.up.sql and {NNN}_{description_in_snake_case}.down.sql
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-add-migration is a skill published in the GitHub repository JotJunior/cstk (24 stars, last pushed 3d ago), licensed MIT. It adds 17 tokens to every session and 1,517 once invoked, about $0.0001 per session on Opus 5.5. 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.
