Corey Haines 30f9b9a729 feat: v2.0 skill renames and CRO consolidation (#291)
* feat: v2.0 skill renames and CRO consolidation

BREAKING CHANGE: Users must reinstall skills after this update.

## Skill Renames (16)
- ab-test-setup → ab-testing
- analytics-tracking → analytics
- aso-audit → aso
- competitor-alternatives → competitors
- email-sequence → emails
- free-tool-strategy → free-tools
- launch-strategy → launch
- onboarding-cro → onboarding
- paywall-upgrade-cro → paywalls
- popup-cro → popups
- pricing-strategy → pricing
- product-marketing-context → product-marketing
- referral-program → referrals
- schema-markup → schema
- signup-flow-cro → signup
- social-content → social

## Consolidations (1)
- page-cro + form-cro → cro (form content in references/form.md)

## Why 2.0?
- Shorter, cleaner skill names
- Consistent naming (no -strategy, -setup, -cro suffixes)
- All cross-references updated across 100+ files

Total skills: 40

* fix(v2.0): update evals for renamed skills, fix validate script, clear warnings

- Update 32 evals.json files to reference new skill names (page-cro → cro,
  product-marketing-context → product-marketing, etc.) — these were missed
  in the initial v2.0 rename pass since only SKILL.md and marketplace.json
  were updated.
- Fix validate-skills.sh: replace GNU-only `head -n -1` with portable awk
  so frontmatter extraction works on macOS.
- Move Copy Editing Checklist (56 lines) to references/checklist.md to
  bring copy-editing SKILL.md under the 500-line limit (508 → 457).
- Add "see X" pointers to marketing-psychology description for skill
  discovery (cro, pricing, copywriting).
- Update skill-request.yml issue template placeholder (page-cro → cro).

All 40 skills now pass validation with zero warnings.

* fix(v2.0): add evals for 8 missing skills, strip stale frontmatter from cro/form.md

Adds 48 new eval cases (6 per skill) for skills that previously had no evals:
aso, co-marketing, community-marketing, competitor-profiling, directory-submissions,
image, lead-magnets, video. All 40 skills now have eval coverage (251 total cases).

Strips leftover frontmatter from skills/cro/references/form.md — it was inherited
from the old form-cro SKILL.md before consolidation. Reference files don't need
frontmatter.

* fix(v2.0): rename paid-ads → ads

One more v2.0 simplification — drops the redundant 'paid-' qualifier. Updates
the skill directory, SKILL.md frontmatter, evals.json, README skill table, the
v2.0 rename table in VERSIONS.md (now 17 renames), and all cross-references in
related skills (ad-creative, aso, competitor-profiling, customer-research,
lead-magnets, marketing-ideas) plus the tools/integrations guides.

* fix(v2.0): bump SKILL.md frontmatter version to 2.0.0 for all 40 skills

VERSIONS.md was already updated to 2.0.0 but the metadata.version field inside
each SKILL.md was still on 1.x. That mismatch would have caused the update-check
flow to perpetually report 'update available' since it compares VERSIONS.md
against local SKILL.md metadata versions.

Caught by codex review (P1).

* fix(v2.0): add legacy product-marketing-context.md filename fallback

Before this fix, users upgrading from v1.x who had a `product-marketing-context.md`
file would lose automatic context loading — every skill only checked the new
`product-marketing.md` filename. Now all 40 skills also accept the legacy
filename (in either `.agents/` or `.claude/`), and the README migration command
covers both legacy and current filenames.

Caught by codex review (P1 + P2).

* fix(v2.0): re-sort README skills table alphabetically, fix ads box width

The skills table had a few entries out of alphabetical order from the renames
(co-marketing was after cold-email, ads was at the renamed position).
Re-sorted alphabetically per sync-skills.js. Also padded the 'ads' cell in the
ASCII flow diagram to keep the box width consistent.

* fix(v2.0): document folder cleanup on upgrade, stop sync-skills from re-adding skills array

README upgrade guide now includes:
- A clear cleanup step for stale v1.x skill folders (renamed + consolidated) so
  users don't end up with both old and new folders side-by-side after upgrading
- The full v1 to v2 rename map for reference
- Existing product-marketing-context.md migration steps (preserved)

sync-skills.js no longer (re-)introduces a `skills` array on marketplace.json --
Claude Code's plugin schema discovers skills via the `skills/` directory, and the
explicit array was failing validation. The script now refreshes the description
count and strips the stale array if present.

Platform Limits Reference

Quick reference for hashtag limits, character counts, and visible text thresholds on each major social platform.


Instagram

Element Limit
Max hashtags 5 (official limit)
Recommended hashtags 3 5
Max caption chars 2,200
Visible before "more" ~125 chars

Facebook

Element Limit
Max hashtags No official limit
Recommended hashtags 1 2
Max post chars 63,206
Ideal for engagement 40 80 chars

TikTok

Element Limit
Max hashtags 5 (since August 2025)
Recommended hashtags 3 5
Max caption chars 4,000
Visible before "more" ~150 chars

LinkedIn

Element Limit
Max hashtags No official limit
Recommended hashtags 3 5
Max post chars 3,000
Visible before "more" ~210 chars

Twitter/X

Element Limit
Max hashtags No official limit
Recommended hashtags 1 2
Max tweet chars 280 (standard) / 25,000 (Premium+)
Visible before "more" Full tweet (280 standard)

YouTube

Element Limit
Max hashtags 15 (exceeding this causes YouTube to ignore ALL hashtags)
Recommended hashtags 3 5
Max title chars 100 (visible before truncation: ~70)
Max description chars 5,000
Visible before "Show more" ~100 chars

The first 3 hashtags in the description automatically appear above the title as clickable links. For Shorts, use 1 5 hashtags.


Pinterest

Element Limit
Max hashtags 20 per pin
Recommended hashtags 2 5
Max pin title chars 100
Max description chars 500
Visible before "More" ~50 chars (desktop)

Pinterest has deprioritized hashtags. Focus on keywords as natural sentences within the description for better SEO instead of relying on hashtags.


Threads (Meta)

Element Limit
Max hashtags 1 per post (topic tag)
Recommended hashtags 1
Max post chars 500
Max with text attachment 10,500 (500 + 10,000 expandable)
Visible without expanding First ~1 2 lines

Threads limits topic tags to one per post. The platform is not hashtag-driven — the algorithm prioritizes content from followed accounts mixed with recommendations.


Usage Tips

  • Hashtags count against character limits on all platforms
  • Front-load your message before the "more" truncation point
  • On Instagram and TikTok, fewer hashtags now outperform hashtag-stuffing
  • On LinkedIn, hashtags at the end of the post perform better than inline
  • On Facebook, hashtags have minimal impact on reach — use sparingly
