Prad Nukala 6406208b35 shell: fish functions -> ~/.local/bin executables + bash/zsh ports; manage ~/.agents

- 16 cross-shell utilities converted to sh/bash chezmoi executables:
  ai c2p cp-appid extract_agents fab gdc gh-sonr-org-migrate ghg-clone
  ghn gho git-summary launch_omp_livediff_overlay lc-elir mdcp mdp pj
  (ghg-clone not named ghg: unrelated cargo binary owns that name)
- cwd/history helpers stay per-shell: yy c cd clip-last + ghg/ghn/gho
  cd-wrappers in bash/functions/ and zsh/functions/, loaded by rc files
- fish keeps only shell-state functions; converted ones now hit PATH
- cp-appid ignore gating moved to .local/bin path
- dot_agents/skills: 82 skills materialized from dotstate storage so
  dot_claude skill symlinks resolve on fresh bootstrap; dotstate
  profile/symlinks.json released .agents/skills .bashrc .zshrc

Browser Rendering Patterns

Basic Worker

import puppeteer from "@cloudflare/puppeteer";

export default {
  async fetch(request, env) {
    const browser = await puppeteer.launch(env.MYBROWSER);
    try {
      const page = await browser.newPage();
      await page.goto("https://example.com");
      return new Response(await page.content());
    } finally {
      await browser.close(); // ALWAYS in finally
    }
  }
};

Session Reuse

Keep sessions alive for performance:

let sessionId = await env.SESSION_KV.get("browser-session");
if (sessionId) {
  browser = await puppeteer.connect(env.MYBROWSER, sessionId);
} else {
  browser = await puppeteer.launch(env.MYBROWSER, { keep_alive: 600000 });
  await env.SESSION_KV.put("browser-session", browser.sessionId(), { expirationTtl: 600 });
}
// Don't close browser to keep session alive

Common Operations

Task	Code
Screenshot	`await page.screenshot({ type: "png", fullPage: true })`
PDF	`await page.pdf({ format: "A4", printBackground: true })`
Extract data	`await page.evaluate(() => document.querySelector('h1').textContent)`
Fill form	`await page.type('#input', 'value'); await page.click('button')`
Wait nav	`await Promise.all([page.waitForNavigation(), page.click('a')])`

Parallel Scraping

const pages = await Promise.all(urls.map(() => browser.newPage()));
await Promise.all(pages.map((p, i) => p.goto(urls[i])));
const titles = await Promise.all(pages.map(p => p.title()));

Playwright Selectors

import { launch } from "@cloudflare/playwright";
const browser = await launch(env.MYBROWSER);
await page.getByRole("button", { name: "Sign in" }).click();
await page.getByLabel("Email").fill("user@example.com");
await page.getByTestId("submit-button").click();

Incognito Contexts

Isolated sessions without multiple browsers:

const ctx1 = await browser.createIncognitoBrowserContext();
const ctx2 = await browser.createIncognitoBrowserContext();
// Each has isolated cookies/storage

Quota Check

const limits = await puppeteer.limits(env.MYBROWSER);
if (limits.remaining < 60000) return new Response("Quota low", { status: 429 });

Error Handling

try {
  await page.goto(url, { timeout: 30000, waitUntil: "networkidle0" });
} catch (e) {
  if (e.message.includes("timeout")) return new Response("Timeout", { status: 504 });
  if (e.message.includes("Session limit")) return new Response("Too many sessions", { status: 429 });
} finally {
  if (browser) await browser.close();
}
