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 | $0.00047 | $0.02074 |
| Opus 5.5 | $0.00019 | $0.00830 |
| Sonnet 5.5 | $0.00009 | $0.00415 |
| Haiku 4.5 | $0.00005 | $0.00207 |
Grade A, and why
upgrade-everything 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 3d 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 — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Upgrade Everything
Audit every version reference in a repository, resolve current upstream versions, evaluate each available upgrade with repo-specific reward and risk, then apply only the upgrades the user explicitly selects.

Workflow
1. Record the Audit Date
Run date before searching for upstream versions. Upgrade data is date-sensitive, so include the exact date in the audit summary and in any later note about unresolved or stale upstream information.
2. Detect Repository Shape
Detect the repository root, project languages, package managers, CI systems, release tooling, and whether the repo is an application, public library, template, plugin marketplace, or monorepo. Exclude generated, vendored, and cache directories from all version searches.
Always exclude at least:
.git/node_modules/.yarn/.lake/vendor/dist/target/.venv/- lockfile cache directories
Use ./references/version-surfaces.md to decide which files and literals to inspect.
3. Discover Version Surfaces
Use the pin-everything surface coverage as the baseline, then add upgrade-specific surfaces. Inventory package manifests and lockfiles, GitHub Actions refs, reusable workflows, language runtime files, Docker and devcontainer images, tool install commands, package manager pins, schema URLs, marketplace and plugin versions, release config versions, and unclassified version-like literals in scripts, docs, and config.
For each discovered surface, record:
- File path and owning ecosystem
- Current value and surrounding context
- Whether a package manager, lockfile, generator, or template owns the value
- Whether the surface is user-facing documentation, executable automation, build metadata, or published API metadata
Do not classify a candidate as out of scope merely because the upgrade looks risky or low value.
4. Resolve Upstream Versions
What ships with it
3 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.

upgrade-everything is a skill published in the GitHub repository cboone/agent-harness-plugins (2 stars, last pushed yesterday), licensed MIT. It adds 47 tokens to every session and 2,074 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 2026-09-03.
