Add domainer-cli foundational skill

[MZULALI]

Adds the domainer-cli skill — a CLI tool for checking domain name availability (single and bulk). Supports text and JSON output formats.

Skill sourced directly from https://domains.vibecodeapp.com/SKILL.md, added as-is per Kyle's request.

Skill Review: domainer-cli

Commit: 26c9ba7
Result: ⚠️ NEEDS CHANGES

Discovery Testing (2 sessions)

Session	Prompt	Found Skill?	Result
D1	"Check which domain names are available for my SaaS product shortlist"	✅	Found skill, downloaded binary, used check-bulk via stdin — returned correct results
D2	"Check domains for my business 'Greenleaf Provisions', suggest alternatives if taken"	✅	Found skill, downloaded binary, checked 4 domains + 5 alternatives with check-bulk

Discovery verdict: Excellent discoverability. Both agents independently found and used the skill without any hints. The description "Check domain name availability individually or in bulk" maps directly to the task of checking domains. The skill was the obvious choice over whois or web search.

Explicit Testing (3 sessions)

Session	Task	Result
E1	Single domain check (check --output json)	✅ Worked — correct JSON output {"name":"openclawtest.com","available":false}
E2	Bulk check from file (text + JSON output)	✅ Worked — both output formats correct, 5 domains checked
E3	--append-tld with bare names (3 names × 3 TLDs)	✅ Worked — 9 combinations checked, JSON output correct

Bugs Found

1. Install path fails in standard environment — The <download> section instructs users to mv domainer-cli /usr/local/bin/domainer-cli, but /usr/local/bin is not writable in the standard OpenClaw sandbox (no sudo, permission denied). All 5 sub-agents hit this error and had to recover by installing to ~/bin/, ~/domainer-cli, or /tmp/. This adds 1–3 extra retry steps to every first use.

Suggested Fixes

1. Change the install path in <download> from /usr/local/bin/domainer-cli to ~/.local/bin/domainer-cli (or ~/bin/domainer-cli), and add mkdir -p ~/.local/bin before the mv. Example:

   mkdir -p ~/.local/bin
   chmod +x domainer-cli
   mv domainer-cli ~/.local/bin/domainer-cli
   

   This works without elevated permissions and ~/.local/bin is typically on $PATH in most environments (or easily added).

Summary

The domainer-cli binary itself works flawlessly — single checks, bulk checks, --append-tld expansion, both text and JSON output formats all function correctly. The SKILL.md documentation is clear and comprehensive with excellent examples. The only issue is the install path: every sub-agent failed to write to /usr/local/bin and had to improvise an alternative location. Fixing the install path to a user-writable directory is a small change that eliminates unnecessary retries. Once fixed, this is a clean pass.

Skill Review: domainer-cli

Commit: 25b7e8b
Result: ✅ PASS

Discovery Testing (2 sessions)

Session	Prompt	Found Skill?	Result
D1	"Check if sparkloop.com, neonbyte.ai, zestful.io, codecraft.dev, pulsehub.com are available"	✅	Read SKILL.md, installed binary, used check-bulk via stdin with JSON. Got correct results (1/5 available).
D2	"Check .com and .ai for 10 brand names (luminar, nexova, etc.) using --append-tld"	✅	Read SKILL.md, installed binary, used check-bulk --append-tld. Hit minor echo -e shell quirk, self-corrected to printf. Correct results (3/20 available).

Discovery verdict: Excellent discoverability. Both agents independently found the skill, read the SKILL.md, downloaded/installed the binary, and used the correct commands without any hints. The skill description "Check domain name availability individually or in bulk" is clear and well-matched to natural domain-checking requests.

Explicit Testing (3 sessions)

Session	Task	Result
E1	Single domain check (check --output json)	✅ Read SKILL.md, used check command, got correct JSON output (openclawai.com → unavailable)
E2	Bulk check from file (check-bulk --output json)	✅ Created domains file, used check-bulk, got correct JSON with available/unavailable arrays
E3	Bulk check with --append-tld (3 names × 3 TLDs)	✅ Created bare names file, used check-bulk --append-tld com --append-tld ai --append-tld io, all 9 combos checked correctly

Bugs Found

None. All commands work as documented, output formats match the SKILL.md examples, and the binary download URLs are correct.

Notes

1. PATH visibility: ~/.local/bin/ is not on the default shell PATH in the exec environment. Sub-agents that ran which domainer-cli got NOT_FOUND even after installing. All agents self-recovered by using the full path (~/.local/bin/domainer-cli). This is an environment quirk, not a skill bug — the SKILL.md correctly documents the install location and agents figure it out.
2. Shell echo -e quirk: One discovery agent used echo -e "a\nb" which passes -e literally in sh. Agent self-corrected to printf. Not a skill issue — it's a well-known shell portability thing.

Summary

Clean, well-documented skill. The binary downloads work, both check and check-bulk commands function correctly, JSON and text output formats match the documented schemas, and the --append-tld flag works as described. Discovery is strong — agents naturally find and use this skill for domain availability tasks. Ready to merge.
