Update all SKILL.md descriptions to lead with what the skill does
(third person) followed by trigger conditions, per Anthropic's
skill authoring docs. All original trigger conditions preserved.
Update description max chars to match Anthropic spec (1024).
Retain workflow-summary warning in skill-anatomy.md to prevent
agents from following descriptions instead of reading full skills.
Add Table of Contents to reference files longer than 100 lines so
Claude can see the full scope of available information even when
previewing with partial reads.
Anthropic's Claude 4 prompting best practices document warns that
newer models overtrigger on strong directive language (Never/Always/MUST)
that was necessary for older models. This replaces aggressive directives
with natural phrasing across skills and agents while preserving all
security-critical rules (OWASP, prompt injection, secrets) unchanged.
Also reframes trunk-based development as "Recommended" with a note
acknowledging alternative branching strategies like gitflow.
The implementation phase now points to context-engineering for guidance
on loading the right spec sections per task instead of dumping the full
spec into context.
Define and Plan phase skills covering structured specifications
before code and decomposing work into verifiable tasks.
