 - Fixed hashline payload parsing to silently treat truly-blank lines as empty `~`-prefixed payload lines when more payload follows in the same run. The previous behavior broke at the blank ("payload line has no preceding +, <, or = operation.") even though the intent is obvious — the only ambiguity is between in-payload blanks and end-of-section blanks, and a one-line lookahead resolves it: blanks that precede a non-payload op still end the run cleanly as section separators. Recovers the common case of forgetting the leading separator on a blank inserted line without changing how trailing blanks between ops behave.
 - Rewrote the hashline edit prompt examples to use an ASCII-only `TITLE = "Mr"` → `"Mrs"` / `"Dr"` motif instead of the previous `" • "` and `"·"` separators. Some agents had been copying the middle-dot literal characters into real edits as if they were format scaffolding (e.g. emitting payload lines like `~	·`), since the demo inserts were near-twins of the existing string. The new example keeps every original op shape (single-line replace, multiline replace, insert AFTER/BEFORE, append, delete, blank, plus both anti-patterns) but uses content that is obviously domain-specific and clearly distinct from any payload separator. Pure prompt change; no parser, schema, or runtime behavior is affected.
 
+- Fixed `discoverAgents()` ignoring `disabledProviders` for the `claude-plugins` provider. Plugin roots from `~/.claude/plugins/` were scanned unconditionally, so agents from Claude Code marketplace plugins continued to appear in `/agents` and the Agent Control Center even when `disabledProviders: [claude-plugins]` was set. The discovery path now checks `isProviderEnabled("claude-plugins")` before calling `listClaudePluginRoots()`, matching how every other capability respects the disabled-providers set. ([#1075](https://github.com/can1357/oh-my-pi/issues/1075))
