Summary

Fixes two outdated details in the Bob harness config:

  1. Rename: The .bob config directory is shared by both IBM Bob IDE and IBM Bob Shell, so the entry should reflect the full product name. Renames the AI_TOOLS entry from Bob Shell to IBM Bob (name + successLabel).

  2. Skills-only: IBM Bob has deprecated slash commands in favour of skills. Removes the Bob command adapter so OpenSpec no longer generates .bob/commands/ files, and adds automatic cleanup of any previously generated command files on the next openspec update.

Changes

  • src/core/config.ts — rename Bob ShellIBM Bob
  • src/core/command-generation/adapters/bob.ts — deleted (dead code)
  • src/core/command-generation/registry.ts — remove bob adapter registration
  • src/core/command-generation/adapters/index.ts — remove bob adapter export
  • src/core/command-surface.ts — add bob to skills-invocable capability path (matches Codex pattern)
  • src/core/migration.ts — add cleanupLegacyBobCommandFiles() — deletes .bob/commands/opsx-*.md only when a replacement skill exists
  • src/core/init.ts + src/core/update.ts — call cleanup after Bob skills are written
  • docs/supported-tools.md — rename entry; mark command path as not generated
  • Tests updated throughout

OpenSpec change

Summary by CodeRabbit

  • New Features

    • IBM Bob now uses skill-based /openspec-* invocations instead of generated command files.
    • Initialization and updates automatically remove legacy Bob command files when replacement skills are installed.
    • Legacy files remain preserved when replacements are unavailable or cleanup cannot be completed.
  • Documentation

    • Updated supported-tool documentation and messaging to identify the tool as IBM Bob.
  • Bug Fixes

    • Prevented removal of unmanaged, incomplete, or unsafe legacy command files during migration.

📝 Walkthrough

Walkthrough

IBM Bob is renamed from Bob Shell and now uses skills-only integration. Its command adapter is removed, Bob becomes skills-invocable, and initialization or updates remove managed legacy command files after successful skill installation.

- Only remove files containing 'argument-hint:' frontmatter (OpenSpec

- Run cleanupLegacyBobCommandFiles on the up-to-date early-return

91-92: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Match argument-hint: only in YAML frontmatter.

Lines 91-92 accept the text anywhere in the file. A user-authored opsx-*.md file can mention argument-hint: in its Markdown body and then be deleted when the replacement skill exists. Parse the opening frontmatter block before checking this field.

Proposed fix
 const content = fs.readFileSync(commandFile, 'utf-8');
-if (!content.includes('argument-hint:')) continue;
+const frontmatter = content.match(/^---\r?\n([\s\S]*?)\r?\n---(?:\r?\n|$)/)?.[1];
+if (!frontmatter || !/^argument-hint:/m.test(frontmatter)) continue;

Status: not ready; deferring to backlog.

The IBM Bob rename makes sense, but I could not substantiate the premise for removing command support. IBM's current documentation still explicitly supports .bob/commands/ and says custom slash commands work across Bob Shell and Bob IDE:
https://bob.ibm.com/docs/shell/features/slash-commands
https://bob.ibm.com/docs/ide/features/slash-commands

The Shell documentation also presents argument-hint as ordinary user-authored command metadata, so that field alone cannot establish OpenSpec ownership before deletion. The new cleanup currently accepts any existing replacement path, without checking that it is a usable generated skill.

Please provide the supported-version/deprecation evidence before retiring the adapter and automatically deleting commands. A rename-only change could be considered independently. No implementation changes made during this review.
