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 | $0.00056 | $0.00546 |
| Opus 5 | $0.00028 | $0.00273 |
| Sonnet 5 | $0.00011 | $0.00109 |
| Haiku 4.5 | $0.00006 | $0.00055 |
Grade A, and why
monorepo-and-tooling 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 11d 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.
What it actually says
Monorepo & Tooling
Announce at start: "I'm using claude-engineer:monorepo-and-tooling to lay out the polyglot monorepo."
The layout (always a monorepo)
One repo, two dependency graphs side by side:
- JS side -
apps/*(React/Next frontends) +packages/*(ui,config,eslint-config,tsconfig), managed by pnpm (default) or Bun workspaces + Turborepo for caching/task orchestration. - Python side -
services/*(FastAPI) +libs/*(shared libs) as uv workspace members sharing oneuv.lock. - Bridge - give each Python service a thin
package.jsonwhose scripts shell out touv, so Turborepo is the single task vocabulary across both languages.
Defaults & decisions
- JS package manager: ask per project (Bun vs pnpm). Default pnpm for stability unless the user prefers Bun.
- Shared
packages/uiholds the design-system components;packages/configholds Tailwind/token config. - Root config:
turbo.json,pnpm-workspace.yaml(or Bun workspaces),pyproject.toml(uv workspace), roottsconfig/eslint base.
Non-negotiables
- Shared code is a package, not copy-paste - design tokens, UI, types, configs live once and are imported.
- Tasks run through Turborepo (
dev,build,lint,typecheck,test) for caching and one vocabulary. - App runs native; services in Docker (
claude-engineer:docker-dev-environment).
Full detail (concrete directory tree, root config files, workspace wiring, pnpm-vs-Bun trade-offs):
read references/polyglot-monorepo.md on demand.
Red flags - STOP
- Duplicated component/token/type code across apps → extract to a
packages/*. - Running tasks ad-hoc per app instead of through Turborepo.
- A single-language repo when the project will clearly have both a frontend and a FastAPI backend.
What ships with it
1 file 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.

monorepo-and-tooling is a skill published in the GitHub repository martian56/claude-engineer (2 stars, last pushed 2mo ago), licensed MIT. It adds 56 tokens to every session and 546 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
Other skills, from other repositories
adopt-project
Apply agent-starter patterns to an EXISTING project - audits the codebase, proposes components by invasiveness tier (hooks, skills, CLAUDE.md, lint configs, patterns), and applies only what the developer approves. Use when the user says adopt, retrofit, "apply agent-starter to this project", or wants starter patterns…
commit-push-pr
Full git workflow - creates branch, commits, pushes, and creates or updates a PR with summary and test plan.
commit
Create a single well-crafted git commit from current changes. Analyzes diff, follows repo's commit style, and writes a concise "why not what" message.
reflect
Per-project self-improvement - reads the .harness ledger and feedback memories, then proposes gated rule/threshold/ADR changes so the project stops repeating mistakes. Run periodically.
remember
Review auto-memory entries and propose promotions to CLAUDE.md, CLAUDE.local.md, or shared memory. Also detects outdated, conflicting, and duplicate entries across memory layers.
dream
Memory consolidation - review, merge, prune, and index memory files. Run periodically to keep memories organized and up-to-date.
