cview AGENTS.md

Repository-specific instructions for coding agents working on cview, a software project. They explain how to set up the project, where different behavior belongs, and which checks verify a change.

In plain words
What is it for?
Use them when changing cview's server, browser, navigation, themes, rendering, exports, or build configuration.
Why use it?
They help an agent follow the project's existing structure and rules instead of making changes in the wrong place or skipping required tests.

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

cview AGENTS.md 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.

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.

AGENTS.md

Repository instructions for coding agents. README.md is the human-facing product and contributor guide; keep agent-specific guidance here.

Bootstrap and verification

Use the Node version in .node-version. In a fresh checkout, install the locked dependencies and Chromium once:

npm run bootstrap

Use the smallest relevant test while iterating, then run the appropriate gate:

npm test -- path/to/file.test.ts  # focused Vitest run
npm run check                     # types, lint, design lint, Vitest, build
npm run check:all                 # check plus production Playwright flows

Run npm run check before handing off any source or configuration change. Run npm run check:all when a change can cross the server/browser boundary or affect navigation, themes, rendering, export, capture, or build configuration. For DESIGN.md-only work, npm run lint:design is the focused gate.

Where behavior belongs

  • src/server.ts composes the app; filesystem, search, security, and HTTP/SSE behavior belongs in focused modules under src/server/.
  • src/shared/contracts.ts parses and normalizes JSONL records and API responses.
  • Frontend transport belongs in api/, pure conversation behavior in domain/, browser lifecycles in hooks/, and screen/display work in pages/ and components/.
  • Live and standalone export behavior belongs in src/frontend/src/export/.
  • For UI or export presentation changes, read DESIGN.md. Semantic colors live in styles/theme.css, shared conversation rules in styles/conversation.css, and typed React references in styles/tokens.ts.

Contracts to preserve

  • Parse Claude records through the shared contracts and keep unknown record kinds visible instead of silently discarding them.
  • Keep ~/.claude read-only and write derived indexes to the external cache. Never copy real session files into tests; use small JSONL files with invented data.
  • Bind to loopback, reject non-local API clients/origins, and validate every project, session, and agent path segment before filesystem access.
  • Keep cold filesystem scans bounded; do not fan out unbounded reads across all sessions.
  • Preserve public CLI names, environment variables, API behavior, stored-data compatibility, message ordering, and stable message IDs unless requested.
  • Standalone HTML must remain offline-capable. Re-export must not nest controls or create multiple toolbars, and capture must work in both themes.
  • Keep heavy export/capture dependencies behind the existing lazy boundary.

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.

cview AGENTS.md is an instructions file published in the GitHub repository 2ykwang/cview (20 stars, last pushed 26d ago), licensed MIT. It adds 652 tokens to every session, about $0.0033 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 2026-08-30.
