Its job is intentionally narrow: - load a small number of high-value notes before acting - write back reusable lessons after the task completes It does not define business schemas. It does not own the browser driver. Pair it with whatever browser control tool you already trust. ## Runtime location Memory is global and shared across all projects. Notes about a website learned in one project are automatically available in every other project. The default location is `~/.site-memory/`. Override with `SITE_MEMORY_HOME` or `--runtime-base `. Resolve it with: ```bash node ./scripts/resolve-runtime-root.mjs ``` Initialize it with: ```bash node ./scripts/init-memory-root.mjs ``` ## Memory shape The runtime root contains: - `INDEX.md` as a compact index - topic files with frontmatter and reusable details Supported note kinds: - `operator` - `guidance` - `context` - `reference` Use them this way: - `operator`: collaboration preferences, pause points, tolerance for automation - `guidance`: reusable rules, warnings, and tactics - `context`: surrounding deadlines or constraints that matter across runs - `reference`: stable selectors, URL patterns, routes, and site structure ## Lookup workflow 1. Build the lookup inputs: ```bash node ./scripts/build-recall-input.mjs --task "" ``` 2. Use the generated selector prompt to choose only the notes that are likely to save real exploration time. 3. Open only the chosen files: ```bash node ./scripts/read-recalled-files.mjs --files "reference/foo.md,guidance/bar.md" ``` 4. Treat recalled notes as leads, not ground truth. Re-check selectors, button labels, URLs, and flows against the live page before relying on them. ## Capture workflow After the browser task ends, build the write-back prompt: ```bash node ./scripts/build-distill-input.mjs --message-count ``` The output contains a `prompt` field. You MUST execute that prompt as an after-action pass. This pass can: - read memory files - search memory files - update files only inside the memory root That pass should: - update an existing topic file when possible - create a new topic file only when the lesson is genuinely new - keep `INDEX.md` short - avoid storing one-off outputs, secrets, or temporary task state ## Design rules - Keep notes generic and reusable. - Save only information that should make a future visit cheaper or safer. - Prefer revising topic notes over appending session logs. - Load only a few notes per task; too much memory becomes noise. - If a remembered selector or route may be stale, verify it before use. ## Browser automation A CDP-based browser control skill is bundled at `./vendor/chrome-cdp-skill/`. Read its instructions before first use: ```bash cat ./vendor/chrome-cdp-skill/skills/chrome-cdp/SKILL.md ``` Use `node ./scripts/cdp-proxy.mjs [args]` for browser interaction. ### Commands All commands use `./scripts/cdp-proxy.mjs`. The `` is a unique targetId prefix from `list`. ```text list List open pages shot [file] Viewport screenshot snap Accessibility tree snapshot nav Navigate and wait for load click Click by CSS selector clickxy Click at CSS pixel coordinates type Type text at current focus eval Evaluate JavaScript html [selector] Full page or element HTML open [url] Open new tab ``` ### Coordinates `shot` saves at native resolution: image pixels = CSS pixels x DPR. CDP input events use CSS pixels: `CSS px = screenshot px / DPR`. ### Tips - Prefer `snap --compact` over `html` for page structure - Use `type` (not eval) to enter text in cross-origin iframes - Chrome shows an "Allow debugging" modal once per tab on first access ## Browser task workflow For repeated browser work, follow these phases in order: ### 1. Prepare the runtime ```bash node ./scripts/init-memory-root.mjs ``` ### 2. Load likely-helpful notes ```bash node ./scripts/build-recall-input.mjs --task " " ``` Read the manifest from the output, choose the strongest matches, then open only those notes: ```bash node ./scripts/read-recalled-files.mjs --files "file1.md,file2.md" ``` ### 3. Browse and verify Use the browser tool to accomplish the objective. If notes mention selectors or routes, verify them on the live page before depending on them. ### 4. Capture durable findings After the task, save only the parts that should help a future visit. For site knowledge, a `reference` note often benefits from a body structure like: ```markdown ## What this site is ## How the site works ## Verified selectors ## Pitfalls ## Successful paths ``` Update `INDEX.md` after writing. If the task produced no durable lesson, skip the write-back. --- > Source: [LittleYier/site-memory](https://github.com/LittleYier/site-memory) — distributed by [TomeVault](https://tomevault.io).
