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 | $0.00051 | $0.01902 |
| Opus 5.5 | $0.00020 | $0.00761 |
| Sonnet 5.5 | $0.00010 | $0.00380 |
| Haiku 4.5 | $0.00005 | $0.00190 |
Grade A, and why
gspdev-runtime-compat 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 — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.
The GSP installer lives at bin/install.js in the repo root. It converts Claude Code's native format into each runtime's expected format. The baseline reference is at ${CLAUDE_SKILL_DIR}/references/baseline.md.
Step 0: Parse request
$ARGUMENTS determines scope:
- A runtime name (
claude,opencode,gemini,codex) — research that runtime only - A concept (
skills,agents,commands,tool-mapping) — compare across all runtimes - A combo (
codex skills,gemini agents) — specific runtime + concept allor empty — full comparison across all runtimes and conceptsdrift— compare docs against current installer and flag mismatches
Step 1: Fetch live documentation
For each runtime in scope, fetch the authoritative docs. Use WebFetch with targeted prompts to extract extension specs.

What ships with it
1 file 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.

gspdev-runtime-compat is a skill published in the GitHub repository jubscodes/get-shit-pretty (55 stars, last pushed 4mo ago), licensed MIT. It adds 51 tokens to every session and 1,902 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.
