# steel-session-debugging Diagnoses failed Steel browser automation sessions using logs, network traces, and replay links. Pinpoints timeouts, unexpected agent actions, and blocked pages. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 432 installs · ★ 4 - Author: steel-dev - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/steel-dev/skills/tree/HEAD/steel-session-debugging/SKILL.md - Updated: 2026-06-04 - HTML: https://affpapa.org/en/nevibecode/skills/steel-session-debugging ## What it does This skill investigates broken Steel browser sessions based on recorded facts rather than guesses. It confirms authentication via `steel doctor --preflight`, then pulls session metadata, browser console logs, agent logs, and semantic traces. Debug artifacts are stored locally in `.steel-debug/` instead of dumping raw payloads into the conversation. Before summarizing the failure, the workflow strips credentials, cookies, tokens, and form values. It reconstructs an execution timeline covering navigations, actions, network failures, and console errors to classify the breakdown against a standard taxonomy. Fixing anti-bot roadblocks is outside its boundary. When the timeline points to bot detection, CAPTCHAs, or proxy reputation issues, the skill gathers evidence and routes the remediation to `steel-reliability`. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add steel-dev/skills --skill steel-session-debugging -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/steel-session-debugging/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/steel-session-debugging/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add steel-dev/skills --skill steel-session-debugging -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/steel-session-debugging/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add steel-dev/skills --skill steel-session-debugging -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/steel-session-debugging/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install steel-dev/skills steel-session-debugging ``` 2. **Manually: put the files in place** - File: `.github/skills/steel-session-debugging/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add steel-dev/skills --skill steel-session-debugging -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/steel-dev/skills --path steel-session-debugging ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/steel-session-debugging/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add steel-dev/skills --skill steel-session-debugging -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/steel-dev/skills/tree/HEAD/steel-session-debugging/SKILL.md ## When to use it - diagnose failed Steel browser automation runs by session ID - build chronological timelines from console logs and semantic traces - strip credentials and private data from debug artifacts - collect evidence before delegating anti-bot fixes to `steel-reliability` ## Example prompts - Investigate why Steel session sess_12345 timed out and show the timeline of events - Extract and redact debug logs for session sess_98765 into .steel-debug/ - Check console errors and replay links for Steel session sess_555 to find the root cause ## Source text · SKILL.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE 8841536a23aaf1e2 ````text --- name: steel-session-debugging description: Use this skill when the user provides a failed Steel session ID, failed automation run, timeout, browser error, blocked page, or unexpected result and wants evidence-backed diagnosis from session metadata, browser logs, raw agent logs, semantic traces, replay links, screenshots, network failures, or errors. Do not use for first-pass bot mitigation; collect evidence here, then hand off to steel-reliability for proxy, CAPTCHA, identity, or anti-bot fixes. license: MIT compatibility: claude-code,codex,cursor,opencode,pi metadata: owner: steel category: debug stage: beta --- # Steel Session Debugging ## Skill Boundary Use this skill to explain what happened in a failed Steel session and what to change next. Start from evidence, not guesses. Do not use this skill as the primary place for bot-detection mitigation, proxy strategy, CAPTCHA strategy, login reputation, or retry policy. If the evidence points there, collect enough proof and hand off to `steel-reliability`. ## Setup Check 1. Confirm the user provided a Steel session ID or enough context to identify one. 2. Run `steel doctor --preflight` if CLI auth or API access is uncertain. 3. Prefer Steel CLI diagnostics before raw API calls. 4. Create local artifacts under `.steel-debug/`; do not paste raw logs into chat unless the user asks. ## Investigation Workflow 1. Collect session metadata, browser logs, raw agent logs, semantic agent traces, and viewer/replay links. 2. Redact cookies, bearer tokens, API keys, passwords, form values, and obvious PII before summarizing. 3. Build a timeline: session creation, navigations, actions, waits, console errors, failed requests, CAPTCHA/proxy signals, and final state. 4. Classify the failure using the taxonomy in `references/failure-taxonomy.md`. 5. Produce an evidence-backed diagnosis with a smallest useful verification step. 6. If the fix involves bot detection, proxy, CAPTCHA, identity, pacing, or login persistence, route to `steel-reliability`. ## Output Format ```text Diagnosis: - What happened: - Most likely cause: - Evidence: - What to change: - Verification step: - Confidence: ``` ## Useful Commands ```bash steel --json sessions get steel --json sessions logs steel --json sessions agent-logs steel --json sessions traces node scripts/collect-session-debug.mjs node scripts/redact-session-debug.mjs .steel-debug//bundle.json node scripts/summarize-session-debug.mjs .steel-debug//redacted-bundle.json ``` ## References - `references/investigation-workflow.md`: detailed collection and timeline process. ```` END THIRD-PARTY FILE 8841536a23aaf1e2 The third-party file has ended.
