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.

What it costs to keep this loaded
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 | $0.00134 | $0.01555 |
| Opus 5 | $0.00067 | $0.00777 |
| Sonnet 5 | $0.00027 | $0.00311 |
| Haiku 4.5 | $0.00013 | $0.00155 |
Grade A, and why
rhdh-yarn-bump 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 10d 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 — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
RHDH multi-repo Yarn bump
Goal
Propagate a Yarn Berry bump (e.g. rhdh-plugins#2918, RHIDP-16074) across:
| Repo | Notes |
|---|---|
redhat-developer/rhdh-plugins |
root workspace (+ Fullsend if hardcoded) |
redhat-developer/rhdh |
root + nested workspaces + Containerfile |
redhat-developer/rhdh-plugin-export-overlays |
many packageManager pins |
redhat-developer/rhdh-cli |
root packageManager / yarnPath (now Yarn 4.17.1) |
gitlab.cee.redhat.com/rhidp/rhdh |
distgit binary + ENV YARN= (copy binary from GH bump) |
gitlab.cee.redhat.com/rhidp/rhdh-plugin-catalog |
per-workspace pins + Containerfiles |
What actually changes
For each matching workspace:
yarn set version <to> # packageManager + yarnPath + .yarn/releases
chmod +x .yarn/releases/yarn-<to>.cjs
yarn install --mode=update-lockfile
Plus pins Yarn cannot see: ENV YARN=, Containerfile / Dockerfile / embedded yarn set version.
No binary download. Bump GitHub repos first (yarn set version produces yarn-<to>.cjs). For GitLab CEE midstream/distgit trees (gitlab.cee.redhat.com/rhidp/rhdh, …/rhdh-plugin-catalog) that only ship a checked-in release + ENV YARN=, copy that same yarn-<to>.cjs into .yarn/releases/ (and remove the old yarn-<from>.cjs), then run the script so text pins update. Use glab against gitlab.cee.redhat.com (not gitlab.com) when opening MRs for those roots.
Use an exact --to (not stable) so every repo matches the Renovate/reference PR.
Script
SKILL=<this skill's directory>
# GH first (4.12/4.14 defaults), then GL CEE (after copying yarn-<to>.cjs into distgit if needed)
node "$SKILL/scripts/bump-yarn.js" --to 4.17.1 \
--root /path/to/rhdh-plugins \
--root /path/to/rhdh \
--root /path/to/overlays \
--root /path/to/rhdh-cli \
--root /path/to/rhdh-downstream \
--root /path/to/rhdh-plugin-catalog
What ships with it
2 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.

rhdh-yarn-bump is a skill published in the GitHub repository redhat-developer/rhdh-skills (16 stars, last pushed yesterday), licensed Apache-2.0. It adds 134 tokens to every session and 1,555 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 2026-08-30.
