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 | $0.00062 | $0.00592 |
| Opus 5.5 | $0.00025 | $0.00237 |
| Sonnet 5.5 | $0.00012 | $0.00118 |
| Haiku 4.5 | $0.00006 | $0.00059 |
Grade A, and why
simplicio-dev-cli 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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

simplicio-dev-cli is a skill published in the GitHub repository wesleysimplicio/simplicio (28 stars, last pushed 1mo ago), with no licence file. It adds 62 tokens to every session and 592 once invoked, about $0.0002 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.
Other skills, from other repositories
tricorder-cli
Full CLI reference for the tricorder daemon (build diagnostics, test results, source lookup, eval comments, logs). This is the fallback invoked by the tricorder skill when the tricorder-mcp MCP tools aren't available or aren't working — invoke tricorder first; it decides whether this is needed.
rpa-bugfix
Run when the user invokes /rpa-bugfix together with a clear bug description (expected vs actual, reproduction). Reproduction test first, then fix, full test suite, short report. Will not work correctly without the bug details.
code-analysis
LSP-based code analysis via mcpls MCP server. Use for compiler-accurate type inspection, go-to-definition, find-all-references, diagnostics, call hierarchy, workspace symbol search, code actions, rename refactoring, and document formatting. Provides real compiler errors — not guesses. Keywords: LSP, language server…
regex
Write, test, and debug regular expressions for pattern matching, search, and text extraction across programming languages. Use when the user asks to match patterns in text, validate input formats (email, URL, IP, phone, date), extract data with capture groups, build search patterns with lookahead or lookbehind, or…
network
Network diagnostics, DNS lookup, port scanning, and connectivity testing. Use when the user asks to check if a host is reachable, trace network routes, resolve DNS records, inspect open ports, debug HTTP requests, check SSL/TLS certificates, test bandwidth, diagnose network latency, or troubleshoot connectivity issues…

Build PowerPoint (PPTX) decks — pptxgenjs when Node is present, python-pptx when not; edit existing decks in place via OOXML — with visual QA before delivery.
