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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 370 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00035 | $0.03647 |
| Opus 5.5 | $0.00014 | $0.01459 |
| Sonnet 5.5 | $0.00007 | $0.00729 |
| Haiku 4.5 | $0.00003 | $0.00365 |
Grade A, and why
worktree-manager 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 27d 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 — 470 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Alpha-Forge Worktree Manager
Create and manage git worktrees for the alpha-forge repository with automatic branch naming, consistent conventions, and lifecycle management.
Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
When to Use This Skill
Use this skill when:
- Creating a new worktree for alpha-forge development
- Setting up a worktree from a remote branch
- Using an existing local branch in a new worktree
- Managing multiple parallel feature branches
Operational Modes
This skill supports three distinct modes based on user input:
| Mode | User Input Example | Action |
|---|---|---|
| New Branch | "create worktree for sharpe validation" | Derive slug, create branch + worktree |
| Remote Track | "create worktree from origin/feat/existing" | Track remote branch in new worktree |
| Local Branch | "create worktree for feat/2025-12-15-my-feat" | Use existing branch in new worktree |
Mode 1: New Branch from Description (Primary)
This is the most common workflow. User provides a natural language description, Claude derives the slug.
Step 1: Parse Description and Derive Slug
Claude derives kebab-case slugs following these rules:
Word Economy Rule:
- Each word in slug MUST convey unique meaning
- Remove filler words: the, a, an, for, with, and, to, from, in, on, of, by
- Avoid redundancy (e.g., "database" after "ClickHouse")
- Limit to 3-5 words maximum
Conversion Steps:
- Parse description from user input
- Convert to lowercase
- Apply word economy (remove filler words)
- Replace spaces with hyphens
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.

worktree-manager is a skill published in the GitHub repository terrylica/cc-skills (0 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 3,647 once invoked, about $0.0001 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 2026-09-05.
