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 | $0.00028 | $0.02591 |
| Opus 5 | $0.00014 | $0.01295 |
| Sonnet 5 | $0.00006 | $0.00518 |
| Haiku 4.5 | $0.00003 | $0.00259 |
Grade B, and why
standalone scanned grade B 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Claude Code Standalone Project Scaffolding
Your goal is to create an initial setup for Claude Code in a pre-existing standalone project, including agent instructions and context information. You work in close collaboration with the user to obtain the required base knowledge about the goals and structure of the project.
Additional user arguments: $ARGUMENTS
Language hint: Always create all generated document content in English, while continuing to speak to the user in the language of their choice.
Platform hint: Instructions and templates assume a Linux host with GNU coreutils. Adapt to the detected user OS.
- macOS — Substitute BSD equivalents for GNU-only utilities.
- Windows — Still use
.shfiles (skip irrelevantchmod +x), assuming Git Bash is available at runtime. Highlight this requirement in the Debriefing. Set"shell": "bash"on command hooks insettings.json. Omit the entiresandboxblock fromsettings.jsonas long as bash sandboxing is unsupported.
Agent Content Principles
When generating content for .md files below, you are writing prompts and context for other AI coding agents.
Follow these principles to optimally tailor your instructions to their needs:
- Concise — Minimize token usage. Prefer keywords and terse bullet points over prose.
- Structured — Use compact Markdown to delineate connected aspects.
- Actionable — Generate concrete operational directives, not abstract guidelines. Avoid aspirational quality statements, general engineering practices, blanket prohibitions.
- Referential — Provide pointers to key code files the agents can read themselves. Do not describe how code works in agent instructions as such duplication leads to drift.
- Scoped — Context is hierarchical. The CLAUDE.md must only contain core project identity and semantics. Rules and agent instructions progressively disclose domain- and task-specific knowledge.
- Durable — Only include details that remain invariant under normal codebase evolution. Avoid specific technology versions. Reference namespaces or search terms instead of single artifacts.

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.

standalone is a skill published in the GitHub repository ralfstrobel/agentic-brownfield-coding (28 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 28 tokens to every session and 2,591 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
manager
Sync session work into GitHub issues, or query track status across repos. Write: find/update issue + W-label. Read: "что по ". Triggers: "создай issue", "синкни сессию", "manager". Not day/week plans (daily-tasks).
weekly-retro
Use when the user is closing an ISO week, reviewing planned outcomes against evidence, interviewing work Areas, resolving unfinished commitments, or asking for "ретро", "weekly retro", "week review", or lessons from the week.
art-director
Orchestrate iterative visual style searches with branch prompts, decision graphs, feedback loops, and final direction selection.
corp-doctor
Use when a Personal Corp operating loop needs setup, repair, a new department, or task routing: HQ files and agent rules, GitHub issue workflow, corp- owner map, department repositories, or deciding which repo an issue belongs to. Triggers: "corp doctor", "почини контур", "заведи отдел", "куда положить задачу"…
html-draft
Use when user wants a standalone HTML diagram in flat engineering blueprint style — architecture diagrams, system flows, technical spec sheets, component maps. Generates one HTML file using Tailwind v4 (browser CDN) for layout and D3 v7 (CDN) for SVG diagrams. User-invoked only — do NOT auto-trigger. Triggers on…
idea
Use when capturing ONE new idea the user voices and wants recorded — "save this idea", "I have an idea", "log this idea", "/idea", "idea: ...". Creates a provenance-tracked folder (one folder per idea) in your ideas repo, dedups against an index, optionally mirrors to a GitHub Project view filtered by label:idea. NOT…
