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 | $0.00096 | $0.10613 |
| Opus 5 | $0.00048 | $0.05306 |
| Sonnet 5 | $0.00019 | $0.02123 |
| Haiku 4.5 | $0.00010 | $0.01061 |
Grade C, and why
release scanned grade C with 1 finding 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
<!-- prettier-ignore --> How it starts
The opening of the file, as written. The whole thing — 945 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Release
Prepare a versioned release or Claude Code marketplace catalog state tag: analyze commits, update release files, create a release commit, tag locally, and optionally publish a GitHub Release.
Options
The user may provide these options inline:
- --major: Force a major version bump regardless of commit analysis
- --minor: Force a minor version bump regardless of commit analysis
- --patch: Force a patch version bump regardless of commit analysis
- --dry-run: Preview all changes without modifying any files, committing, or tagging
Workflow
1. Pre-Flight Checks
Run these commands in parallel to understand the current state:
# Check for uncommitted changes
git status --porcelain
# Get current branch name
git branch --show-current
# List existing version tags, sorted by version
git tag --list 'v*' --sort=-version:refname
# List existing Claude Code marketplace catalog state tags
git tag --list 'catalog-M*-m*-p*-n*' --sort=-creatordate
# Get today's date
date +%Y-%m-%d
# Check for a release workflow that publishes GitHub Releases automatically
if [ -d .github/workflows ]; then
for f in .github/workflows/*.yml .github/workflows/*.yaml; do
[ -f "$f" ] || continue

# `- "v*"` or `- catalog-*`.

# Marketplace push-to-main automation: workflow invokes the canonical
# catalog state computation, publishes a GitHub Release, AND triggers
# on push to the default branch (main or master). All three are
# required. The compute-catalog-state and gh release create checks
# rule out partial automation (e.g., a validation workflow that
# computes the catalog state without tagging or releasing). The push
# trigger check rules out workflow_dispatch-only or PR-only workflows
# that happen to mention both strings: those will not run when a
# commit lands on main, so deferring to them would silently skip
# local catalog tagging and leave nothing tagged or released. The
# branches:/main match must occur *under* push: rather than under a
# sibling key like pull_request: -- otherwise a workflow with
# `pull_request: branches: [main]` would falsely match. The awk
# script tracks indentation to scope branches: matches to the push:
# block, and handles both inline (`branches: [main]`) and YAML-list
# (`branches:` followed by `- main`) forms.

What ships with it
5 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.

release is a skill published in the GitHub repository cboone/agent-harness-plugins (2 stars, last pushed 1mo ago), licensed MIT. It adds 96 tokens to every session and 10,613 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
release
Run the local Agent Safehouse release flow: inspect commits since the last published release, propose the next SemVer version and changelog, present a dry-run for confirmation, then update changelog, publish the GitHub release, and publish the stable Homebrew tap when confirmed.
changelog-draft
Generate a reviewable changelog draft from PRs merged in a release range. Extracts explicit CHANGELOG markers, classifies unmarked PRs, adds external contributor attribution, and outputs markdown + JSON artifacts. Does NOT mutate channelversions.json.
release-peekaboo
Peekaboo release: notarization, npm/GitHub release, appcast, verify, closeout.
classify-changelog-pr
Reference guidance for classifying whether an unmarked PR should appear in the changelog and under which category. Used inline by the changelog-draft skill — not dispatched as a separate agent.
promote-feature
Promote a feature-flagged feature to Dogfood, Preview, or Stable in the Warp codebase. Use when a feature behind a FeatureFlag is ready to roll out to a broader audience, including wiring up the compile-time/runtime bridge and deferring flag cleanup safely.
release
Cut a new release: create the release branch (staging bake), then dispatch the production Release run on that branch.
