local-dev-setup

A project-specific setup guide for contributors developing noisy-coding locally. It connects a local development server, its tools, and project hooks so a coding session can use the checkout’s development version.

In plain words
What is it for?
Use it when preparing the local development environment, starting or verifying the development daemon, connecting the local MCP service, or rebuilding the dashboard.
Why use it?
It helps fix a stopped local server and prevents contributors from accidentally exposing the development setup to end users. It also documents the checks needed after code or dashboard changes.

Token cost

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.

Security

Grade A, and why

local-dev-setup scanned grade A 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Local dev environment for noisy-coding contributors

This skill lives in .claude/skills/ — project scope, for people hacking on THIS repo. It is deliberately NOT in the plugin's skills/ directory, so it never ships to end users.

The full recipe with rationale is docs/local-development.md — read it when anything here surprises you. Quick path:

1. Dev daemon (port 7765; production keeps 8765–8767)

scripts/dev_daemon.sh

Builds the dashboard if dashboard/dist is missing, then starts the listener from this checkout. Verify: curl -s http://127.0.0.1:7765/status returns JSON. Dashboard: http://127.0.0.1:7765 — amber logo + LOCAL DEV badge.

Run it in the background (run_in_background) and restart it after changing Python code; rebuild (cd dashboard && npm run build) after dashboard changes.

2. Session wiring — should already be in place

  • MCP is per contributor machine (LOCAL scope — a committed .mcp.json would be auto-loaded by the plugin and leak the dev server to end users):

    claude mcp add noisy-coding-dev --scope local \
      --env NOISY_CODING_LISTENER_PORT=7765 -- uv run noisy-coding-mcp
    

    Tools appear as mcp__noisy-coding-dev__* after a restart.

  • Hooks are committed to this repo, so normally there is nothing to do: .claude/settings.json → the five hooks duplicated with local commands (NOISY_CODING_LISTENER_PORT=7765 python3 hooks/<script>.py). They run IN ADDITION to the global production hooks — that is intended; each set talks to its own daemon.

If either is missing, restore it from docs/local-development.md §2.

Verify against the DAEMON, not just Vite

Vite serves public/ and its own module graph, masking daemon-side gaps: the avatars sprite worked on :5173 for hours while the container 404'd it (the daemon's static route didn't know the file). Any change involving static files, routes or daemon-served behavior must be checked on the daemon port (7765 dev / 8765 prod build) — ideally with a headless-Chrome screenshot — before calling it done.

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.

local-dev-setup is a skill published in the GitHub repository noisy/noisy-coding (6 stars, last pushed 3d ago), licensed MIT. It adds 77 tokens to every session and 757 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
