Competitive Matrix

Researches a market or technology space and renders an interactive, color-coded comparison matrix in the browser by combining web research with a zero-dependency HTML table.

Workflow

1. Identify the space — confirm the market, product category, or technology being compared; ask for clarification if ambiguous. See RESEARCH.md.
2. List the players — enumerate 5-10 key competitors or options to include; no more, no fewer. See RESEARCH.md.
3. Choose evaluation dimensions — select 5-8 columns relevant to this specific domain; avoid generic filler columns. See RESEARCH.md.
4. Research each player — run at least one web search per player to verify current status and ratings; never rely solely on training data. See RESEARCH.md.
5. Assign ratings — score every cell using the four-point scale (checkcheck/check/tilde/x) with evidence from step 4. See RESEARCH.md.
6. Write the HTML file — write a complete self-contained file to /tmp/matrix.html using the template with color-coded cells, sort, and filter. See TEMPLATE.md.
7. Render in browser — follow _shared/chrome-devtools-render.md to open /tmp/matrix.html, wait for render, and screenshot. wait_for the first competitor name.
8. Deliver as HTML. Upload the existing /tmp/matrix.html to S3 following the shared HTML delivery pattern in _shared/html-delivery.md (skip markdown-to-HTML conversion since HTML already exists). Report name: competitive-matrix. TLDR includes space name, player count, and standout winner(s).
9. Deliver summary — after the screenshot, output 3-5 bullet points naming the key differentiators and the standout winner(s) per use case.

Self-review checklist

Before delivering, verify ALL:

• At least one web search was run per player — no player was rated from training data alone
• Between 5 and 10 players are in the matrix — not fewer, not more
• Between 5 and 8 evaluation dimension columns are present — plus a Verdict column as the last column
• Every cell has a rating from the four-point scale: checkcheck, check, tilde, or x — no blanks, no numbers
• Every cell is color-coded: green for checkcheck, blue for check, orange for tilde, red for x
• A "Last updated: YYYY-MM-DD" line appears above the table in the rendered HTML
• Sort works on every column — clicking a header reorders rows
• Filter input is present and filters by competitor name (case-insensitive)
• Dark background (#1e1e2e) is applied — not white or gray
• Screenshot was taken after wait_for — not immediately after new_page
• HTML version uploaded to S3 with commuter link (unless --no-html or upload failed with noted fallback)
• Slack/chat delivery uses TLDR + link, not the full report

Golden rules

Hard rules. Never violate these.

1. Never rate from training data alone. Run at least one web search per player before assigning any rating. Training data goes stale; search results do not.
2. Always use the four-point scale exclusively. The only valid ratings are checkcheck (excellent), check (good), tilde (partial/mixed), and x (poor/missing). Never use numbers, percentages, stars, or prose in cells.
3. Always include a Verdict column as the last column. Every row must end with a 5-10 word phrase summarizing that player's position.
4. Always color-code every cell. Green (#27ae60) for checkcheck, blue (#2980b9) for check, orange (#d35400) for tilde, red (#c0392b) for x. A matrix where all cells look the same is broken.
5. Never include more than 10 players. Matrices with more than 10 rows become unreadable. If the user lists more, select the 10 most relevant and note the exclusions.
6. Always include a "Last updated" date. Competitive landscapes change. The date the research was conducted must appear above the table in the rendered output.
