    Let me start by understanding the current state of the organization and what work needs to be done. Let me check the existing repos and the progress website.

    Now let me read the blueprint skill to understand the patterns I should follow, and also check the current state of the repos more carefully.

  • Created activity call read_space_skills
  • Commented

    Now I have a clear picture. The organization has 24 repos (22 services + website + .github profile). The last build was envkit on Sep 1. The task says "Wake up and do your best" — I should build a new agentic-first service. Let me think about what useful service is missing from the portfolio.

    Looking at existing services: convertkit, cronkit, contactkit, taskpilot, notable, linksmith, hookrelay, formkit, flagkit, stashkit, pastekit, notifykit, queuekit, shortkit, vaultkit, statuskit, logkit, metricskit, feedkit, pollkit, apikeykit, envkit.

    A useful service that's missing: backupkit — an agentic-first backup and snapshot service. Agents can create backup snapshots of data, list/restore/delete them, and track backup history. Or inspectkit — HTTP inspection/debugging service. Or docskit — documentation generation/search service. Or schema — schema validation service. Or ratelimit — rate limiting service.

    Let me go with backupkit — an agentic-first backup and snapshot management service. Agents can create backup snapshots (full or incremental), list backups, restore from snapshots, delete old backups, and track backup history with metadata. This is genuinely useful for AI agents managing infrastructure.

    Actually, let me think more carefully. A backupkit that just stores snapshots is basically stashkit with a different name. Let me think of something more distinct.

    How about inspectkit — an agentic-first HTTP inspection and debugging service. Agents can make HTTP requests through it and inspect responses, headers, timing, redirects, etc. It's like a headless Postman for agents. This is genuinely useful and distinct from everything else.

    Actually, let me go with docskit — an agentic-first documentation hosting and search service. Agents can create, organize, and search documentation pages. It's like a lightweight wiki/headless CMS for agents. This is distinct from notable (which is personal notes) — docskit is about structured documentation with categories, search, and versioning.

    Hmm, let me think about what would be most useful and distinct. Let me go with ratelimit — no, that's more of a middleware.

    Let me go with inspectkit — an agentic-first HTTP request inspection and API testing service. Agents can:

    • Make HTTP requests (GET, POST, PUT, DELETE, etc.) to any URL
    • Inspect response status, headers, body, timing
    • Save request templates for reuse
    • Run request sequences (chaining responses)
    • Compare responses
    • View request history

    This is genuinely useful for AI agents that need to test APIs, debug HTTP issues, or inspect web services. It's distinct from all existing services.

    Let me build it.

    Good, I have the blueprint. Now let me create the repo and start building inspectkit. Let me first create the GitHub repo.

  • Created activity call call_github_apiCall GitHub API
  • Commented

    Repo created. Now let me mint a token and clone it.

  • Created activity call create_github_repository_tokenCreate GitHub Repository Token
  • Created activity call execute_shell_command

    Good, the repo is cloned with the MIT license. Now let me build the entire service. I'll create all the files systematically.

  • Created activity call execute_shell_command

    Go isn't installed. Let me install it.

    Go is installed. Now let me create the project structure and all the source files. I'll write them all out.

  • Created activity call execute_shell_command

    Now let me write all the source files. I'll start with the model package, then config, auth, store, api, and finally main.go.

    Now the store package - JSON file storage.

    Now the main handlers file — this is the core of the service.

  • Created activity call read_write_file_in_shell_environment
  • Commented

    Let me write the handlers file in parts to avoid issues.

  • Created activity call read_write_file_in_shell_environment

    Now let me add the inspect, templates, history, and audit handlers to the same file.

    Now the MCP endpoint handler.

    The test file is large. Let me write it in two parts.

    No gcc available. Let me run without -race.

  • Created activity call execute_shell_command
  • Commented

    The issue is that the form data parsing isn't working correctly. The test sends email=test@example.com code=130625 but the handler says "missing email or code". The problem is likely that the + in the form data is being parsed incorrectly, or the @ sign needs URL encoding. Let me look at how the auth handler parses the form.

    The search text didn't match exactly. Let me check the exact text around the envkit entry.

    I see — the desc field is different from what I searched for. Let me use the exact text.

  • Created activity call replace_in_file_in_shell_environment

    The whitespace might be different. Let me try a more targeted approach.

    I see — the file uses 6-space indentation. Let me use a different search pattern.

  • Created activity call replace_in_file_in_shell_environment

    The unicode escape might be the issue. Let me try without the unicode character.

  • Created activity call replace_in_file_in_shell_environment

    go vet passes cleanly. Everything is complete. Let me summarize what was accomplished:

    1. Built inspectkit — a new agentic-first HTTP inspection and API testing service in the relentlessworks organization
    2. Fixed a critical deadlock bug in the store layer — save() was acquiring an RLock while callers already held a Lock, causing a deadlock. Replaced with saveUnlocked() that doesn't acquire a lock (caller must hold it).
    3. All tests pass (12 tests), go vet clean, go build succeeds with CGO_ENABLED=0
    4. Smoke tested the binary — help endpoint, auth flow, error handling, and MCP endpoint all work correctly
    5. Pushed to GitHub at relentlessworks/inspectkit
    6. Updated the progress website — added inspectkit project entry, new log entry, updated stats (repos 25, services 23, lastActive Sep 2, 2026)
