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 | $0.00080 | $0.00611 |
| Opus 5 | $0.00040 | $0.00305 |
| Sonnet 5 | $0.00016 | $0.00122 |
| Haiku 4.5 | $0.00008 | $0.00061 |
Grade A, and why
cli-forge-arch 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 — 40 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.
Gotchas — read ../gotchas.md before producing output to avoid known mistakes.
Arch Router — HLD / LLD Dispatcher
This skill has been split into two focused skills. Route the user's request accordingly:
Routing Table
| Signal in user's request | Delegate to |
|---|---|
| "HLD", "system design", "architecture", "C4 context/container", "capacity", "back-of-envelope", "ATAM", "Gate review", "design proposal" | /cli-forge-hld |
| "LLD", "detailed design", "class diagram", "sequence diagram", "API spec", "DB schema", "component design", "STRIDE", "threat model" | /cli-forge-lld |
| "design doc", "tech spec" (ambiguous) | Ask the user: "Do you want a high-level design (system architecture, C4 L1-L2, capacity estimation, ADRs) or a low-level design (class diagrams, API contracts, DB schemas, sequence diagrams)?" |
| Both mentioned | Produce HLD first, then LLD for each key container |
What changed
The original cli-forge-arch combined HLD and LLD in a single skill. This caused issues:
- Users asking for HLD got LLD-level detail (class diagrams, DB schemas) they didn't need
- Users asking for LLD got HLD-level context (system diagrams, capacity) that was redundant
- The skill was too large to produce focused, high-quality output
New skills:
cli-forge-hld— C4 L1-L2, capacity estimation, ADRs, ATAM tradeoff analysis, deployment architecturecli-forge-lld— C4 L3-L4, class/sequence/state diagrams, API contracts, DB schemas, STRIDE, testability
The references/ directory is preserved here for backward compatibility but the canonical references now live in each skill's own references/ directory.
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.

cli-forge-arch is a skill published in the GitHub repository Destynova2/cli-code-skills (5 stars, last pushed 10d ago), licensed MIT. It adds 80 tokens to every session and 611 once invoked, about $0.0004 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.
