codebase-tour

A short orientation command for the career-operations web app’s codebase. It explains the server, browser interface, tests, parent-project integration, streaming endpoints, and project rules.

In plain words
What is it for?
Use it when joining the repository or starting work without prior context. It covers the Node and Express server, vanilla JavaScript screens, tests, shared parent paths, server-sent event streams, and documentation entry points.
Why use it?
It reduces the time an unfamiliar coding agent needs to understand where code lives and how the parts connect. This lowers the risk of starting in the wrong file or breaking a project boundary.

Made for: Claude Code.

Per session 20 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 261 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

codebase-tour 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 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.

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

Walk through the repo in this order, ONE sentence per item:

  1. Stack — Node 18+, Express 4, vanilla SPA, no build step, no TS.
  2. Server entry — server/index.mjs (createApp factory + ~50 routes).
  3. Server lib — list server/lib/*.mjs with a one-line purpose each.
  4. Client entry — public/index.htmlpublic/js/app.jspublic/js/router.js.
  5. Views — public/js/views/*.js, one per route.
  6. Tests — node --test tests/*.test.mjs, in-process via createApp().
  7. Parent integration — paths.mjs::resolveProjectRoot() finds the parent career-ops; this UI reads/writes via PATHS.*.
  8. Streaming — /api/stream/* endpoints emit SSE for long-running scans / PDF generation.
  9. Hard rules — never edit outside web-ui/, never log secrets, never relax CSP.
  10. Where to start — docs/architecture/OVERVIEW.md.

Output as a numbered list. Under 250 words.

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.
