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 | $0.00038 | $0.00216 |
| Opus 5 | $0.00019 | $0.00108 |
| Sonnet 5 | $0.00008 | $0.00043 |
| Haiku 4.5 | $0.00004 | $0.00022 |
Grade A, and why
internal/mdm 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 2d 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
Master Data Management (internal/mdm)
This module is the Universal Translator of the matrix. It maps isolated domain entities (e.g., a "Customer" in Revenue and a "Vendor" in Supply Chain) back to a single Golden Record representing a real-world company.
Constraints
- Zero Foreign Keys:
LocalIDacts as a pure pointer to another domain's physical row. - Physical Hierarchy:
EntityMappingis interleaved underGlobalEntityin Cloud Spanner to ensure instant mapping resolution without SQL joins.
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.

internal/mdm is a skill published in the GitHub repository quantDIY/GERP (3 stars, last pushed 5mo ago), licensed MIT. It adds 38 tokens to every session and 216 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.

check-and-commit
Pre-commit verification gate — runs Carbon's validation gates in order (generate:types if schema changed, biome, scoped typecheck, scoped tests, build if needed, and /translate to fill missing i18n .po strings when UI/locale files changed), fixes straightforward failures, then commits the specific files with a…
translate
Fill missing i18n translations in the Lingui .po catalogs cheaply and CONSISTENTLY — extract every empty msgstr, attach the approved domain terminology from packages/locale/locales/glossary.json, fan out chunked jobs to Haiku subagents (model override, not the main model), merge results back deterministically, then…
