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 | $0.00046 | $0.01444 |
| Opus 5.5 | $0.00018 | $0.00578 |
| Sonnet 5.5 | $0.00009 | $0.00289 |
| Haiku 4.5 | $0.00005 | $0.00144 |
Grade A, and why
challenge-plan 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.
The source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
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.

challenge-plan is a skill published in the GitHub repository gitkraken/vscode-gitlens (9,958 stars, last pushed today), with no licence file. It adds 46 tokens to every session and 1,444 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.
Other skills, from other repositories
code-review
Analyze code changes between two local Git branches and perform a comprehensive code review. Use ONLY for local git branch comparisons. Do NOT use when a GitLab or GitHub MR/PR URL or MR ID is provided — use gitlab-cli or github-cli skill instead.
bitbucket-cli
Perform Bitbucket operations using the Bitbucket REST API via curl. Use for repositories, pull requests, pipelines, and issues. ALSO use this skill when asked to review a Bitbucket PR — when a Bitbucket PR URL or PR ID is provided, fetch and review the diff instead of the code-review skill.
gh-address-comments
Fetch all review comments and threads on the current branch's open GitHub PR using the gh CLI, present a numbered summary, and address the ones the user selects.
ci-cd
CI/CD pipelines for GitHub Actions and Docker-based deployments — lint, test, build, push, deploy stages; environment secrets; branch-gated workflows; health-check rollbacks; and PM2/systemd service restarts.
github-pr-workflow
Prepare a GitHub pull request from a feature branch — branch hygiene, commit shape, title/body, verification notes, screenshots for UI work, and replies to review comments.
compiler-commit
Use when you want to verify compiler changes and commit with the correct convention. Runs tests, lint, and format, then commits with the [compiler] or [rust-compiler] prefix.
