Track upstream fixes for context: fork in plugin skills

[laurigates]

Summary

context: fork in skill frontmatter is currently unusable for plugin-based skills due to two upstream issues in Claude Code. This issue tracks when those are resolved so we can re-enable fork isolation.

Current Workaround

Removed context: fork from all 11 affected skills, keeping agent: general-purpose for subagent isolation. Updated .claude/rules/skill-fork-context.md to document the current status.

Upstream Issues to Monitor

Issue	Status	Impact
anthropics/claude-code#16803	OPEN	context: fork silently ignored for plugin-installed skills
anthropics/claude-code#33154	OPEN	[1m] context models hit cascading rate limits with concurrent subagents
anthropics/claude-code#27053	NOT_PLANNED	Subagents permanently return rate limit with total_tokens: 0
anthropics/claude-code#6594	NOT_PLANNED	One rate-limited subagent kills all parallel siblings

When to Revisit

When both #16803 and #33154 are resolved:

1. Re-add context: fork to the 11 skills listed in the removal PR
2. Update .claude/rules/skill-fork-context.md to re-recommend fork for verbose skills
3. Test with Opus 4.6 (1M context) sessions to verify no rate limit errors

Summary

context: fork cannot be re-enabled yet. Both blocking issues (#16803 and #33154) remain open with no fix in sight.

Notable observations:

• #16803 is still very active — community members are reporting it broken in v2.1.80+ as recently as April 9, 2026. The bug is confirmed to be plugin-specific: context: fork works in ~/.claude/skills/ but not from installed plugins.
• #33154 has drifted in scope — it's now labeled area:cowork (Claude Cowork product) rather than Claude Code CLI specifically. The rate limit cascade issue with concurrent subagents may not be the right issue to track for CLI use. Worth checking if there's a separate CLI-specific issue.
• #27053 and #6594 were both auto-closed as stale by the bot, not fixed. The underlying problems may still exist.

No code changes are needed at this time — the workaround (using agent: general-purpose without context: fork) remains the right approach until #16803 is resolved.
