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 | $0.00090 | $0.00922 |
| Opus 5 | $0.00045 | $0.00461 |
| Sonnet 5 | $0.00018 | $0.00184 |
| Haiku 4.5 | $0.00009 | $0.00092 |
Grade A, and why
prepare-package-release 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Prepare Package Release
Keep the release version synchronized, update the repository wiki from the complete release diff, and leave tag and artifact creation to the publish workflow.
Follow the workflow
-
Inspect
git status, the branch diff againstorigin/main,package.json, the plugin manifests, and the current release guidance:git fetch origin main --tags git diff --stat origin/main...HEAD codealmanac show guides/release/prepare-package-release -
Confirm the intended semantic version. Treat
package.jsonas the release version source of truth. Ask the user if the task does not establish the bump level. -
Run npm's version command without creating a commit or tag:
npm version <patch|minor|major|version> --no-git-tag-versionSynchronize that exact version in:
package-lock.jsonat the rootversionandpackages[""].version;.codex-plugin/plugin.json;.claude-plugin/plugin.json;.claude-plugin/marketplace.jsonat both the plugin version and npm source version.
Do not create or push a release tag. The publish workflow creates the tag and GitHub Release after merge.
-
Find the previous release tag after the manifests are synchronized:
previous_release_tag="$( git describe --tags --match 'rudder-plugin-v*' --abbrev=0 )" release_range="${previous_release_tag}..HEAD"Stop and ask the user if no previous release tag exists. Do not use
origin/mainas the source boundary. Merged changes since the previous tag still belong to the release. -
Run CodeAlmanac Ingest for every version bump. Give it the complete committed release range plus staged and unstaged edits:
guidance="Update durable release knowledge and version claims." guidance+=" A no-op is valid." codealmanac ingest "git:range:${release_range}" git:diff \ --title "Document Rudder release <version>" \ --guidance "$guidance"
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.

prepare-package-release is a skill published in the GitHub repository RudderCode/Rudder (23 stars, last pushed 13d ago), licensed Apache-2.0. It adds 90 tokens to every session and 922 once invoked, about $0.0005 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.
