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 | $0.00133 | $0.02853 |
| Opus 5 | $0.00067 | $0.01426 |
| Sonnet 5 | $0.00027 | $0.00571 |
| Haiku 4.5 | $0.00013 | $0.00285 |
Grade A, and why
cli-forge-lld 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.
How it starts
The opening of the file, as written. The whole thing — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Optimization: This skill uses on-demand loading. Heavy content lives in
references/and is loaded only when needed.
Language rule: Skill instructions are written in English. When generating user-facing output, detect the project's primary language (from README, comments, docs, commit messages) and produce the document in that language. If the project is bilingual, ask the user which language to use before proceeding.
Diacritics rule: When the chosen output language uses diacritics (French, Spanish, Portuguese, etc.), render them correctly — including on capitals (É, À, Ç, Ô…). Never strip accents to ASCII: write "sécurité" not "securite", "Rôle" not "Role". ASCII-flattened French is a defect, not a style.
Writing style: Favor clarity — short sentences, one idea per sentence, plain words. A metaphor only when it clarifies. Keep one consistent register (impersonal/infinitive for operational docs). Separate narrative prose, meant to make the reader understand, from telegraphic content (tables, commands, checklists) which stays terse for action.
No fabricated output: Never invent command output, console captures, API responses, metrics, or logs. When real output is needed, emit a clearly-marked placeholder (🚧 "replace with a real capture"), never plausible-but-fake text presented as real.
Forge LLD — Low-Level / Detailed Design
Translate an HLD's "what" into the "how" — detailed enough that a developer can implement without ambiguity. (Robert C. Martin, Clean Architecture)
Core Principles
- Mitosis — the document grows only the sections the component actually needs. A stateless function doesn't need a state machine. A read-only service doesn't need a migration plan. Kill empty sections, don't fill them with boilerplate
- Implementable precision — every included section must be specific enough to code from. No hand-waving
- Contract-first — define API contracts and interfaces before internals
- SOLID by default — design visible in class diagrams must respect SOLID; flag violations explicitly
- Patterns justified — only document a pattern when its use is non-obvious from reading the code
- KISS — one clear diagram beats two pages of prose. One code example beats three paragraphs of explanation. Readers are developers — they scan for interfaces, schemas, and contracts
- Gotchas — read
../gotchas.mdbefore producing output to avoid known mistakes
What ships with it
4 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.

cli-forge-lld is a skill published in the GitHub repository Destynova2/cli-code-skills (5 stars, last pushed 10d ago), licensed MIT. It adds 133 tokens to every session and 2,853 once invoked, about $0.0007 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.
