link-building is a skill in coreyhaines31/marketingskills, last changed 19 Oct 2026. It can name web addresses.
When the user wants to earn backlinks or third-party mentions that lift rankings and AI citations. Also use when the user mentions 'link building,' 'linkbuilding,' 'backlinks,' 'get more backlinks,' 'link prospecting,' 'link gap,' 'competitor backlinks,' 'unlinked mentions,' 'link reclamation,' 'broken link building,' 'resource pages,' 'guest posting,' 'get into best-of lists,' 'listicle outreach,' 'domain rating,' 'referring domains,' 'anchor text,' or 'is this link vendor safe.' Use this whenever rankings stall on authority or someone wants off-site mentions that AI engines cite. Never recommend buying links that pass ranking credit: paid or exchanged placements get rel=sponsored or nofollow. For press coverage and journalist requests, see public-relations. For directories, see directory-submissions. For reviews, see referrals. For Reddit and communities, see community-marketing. For on-site AI citation work, see ai-seo.

Pattern check
Pattern check: nothing flagged · commit 88c79f6 · 3 Nov 2026
We checked every text file in this skill, at commit 88c79f6 on 3 Nov 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.
How the check worksReport an incorrect finding
Outside links we did not follow
- https://linkdr.com
Format check
Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.
Agent Skills specPasses with warnings
The open format from agentskills.io, held to the strictest version of each rule among the agents we check.
- Warning
Paths that may not work once the skill is installed: line 141: ../../tools/integrations/ahrefs.md (outside the skill folder), line 141: ../../tools/integrations/semrush.md (outside the skill folder), line 141: ../../tools/integrations/dataforseo.md (outside the skill folder), line 142: ../../tools/integrations/exa.md (outside the skill folder), line 142: ../../tools/integrations/firecrawl.md (outside the skill folder) and 1 more. B6
Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.
- Note
Anthropic's packaging script leaves these out: evals/. F8
Fix: Delete them, or list them in .gitignore.
- Note
There is no license field, so readers can't tell whether they may reuse the skill. O2
Fix: Add license: with an SPDX name such as MIT or Apache-2.0, or the name of a bundled licence file.
- Note
Reference files over 100 lines with no table of contents at the top: references/prospecting-and-outreach.md (115 lines). B5
Fix: Add a short list of the sections at the top of each.
- Warning
Claude CodePasses with warnings
Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.
- Warning
Paths that may not work once the skill is installed: line 141: ../../tools/integrations/ahrefs.md (outside the skill folder), line 141: ../../tools/integrations/semrush.md (outside the skill folder), line 141: ../../tools/integrations/dataforseo.md (outside the skill folder), line 142: ../../tools/integrations/exa.md (outside the skill folder), line 142: ../../tools/integrations/firecrawl.md (outside the skill folder) and 1 more. B6
Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.

Fix: Delete them, or list them in .gitignore.
- Note
Reference files over 100 lines with no table of contents at the top: references/prospecting-and-outreach.md (115 lines). B5
Fix: Add a short list of the sections at the top of each.
- Warning
Claude apps & API uploadPasses with warnings
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Warning
Paths that may not work once the skill is installed: line 141: ../../tools/integrations/ahrefs.md (outside the skill folder), line 141: ../../tools/integrations/semrush.md (outside the skill folder), line 141: ../../tools/integrations/dataforseo.md (outside the skill folder), line 142: ../../tools/integrations/exa.md (outside the skill folder), line 142: ../../tools/integrations/firecrawl.md (outside the skill folder) and 1 more. B6
Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.
- Note
Anthropic's packaging script leaves these out: evals/. F8
Fix: Delete them, or list them in .gitignore.
- Note
The description is 936 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4
Fix: If the claude.ai upload refuses it, trim the description to 200 characters.
- Note
Reference files over 100 lines with no table of contents at the top: references/prospecting-and-outreach.md (115 lines). B5
Fix: Add a short list of the sections at the top of each.
- Warning
OpenAI (Codex & API)Passes with warnings
Codex finds SKILL.md by its exact name and needs a description; OpenAI's Skills API checks the frontmatter against the spec and caps uploads.
- Warning
Paths that may not work once the skill is installed: line 141: ../../tools/integrations/ahrefs.md (outside the skill folder), line 141: ../../tools/integrations/semrush.md (outside the skill folder), line 141: ../../tools/integrations/dataforseo.md (outside the skill folder), line 142: ../../tools/integrations/exa.md (outside the skill folder), line 142: ../../tools/integrations/firecrawl.md (outside the skill folder) and 1 more. B6
Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.
- Note
Anthropic's packaging script leaves these out: evals/. F8
Fix: Delete them, or list them in .gitignore.
- Warning
VS Code & CopilotPasses with warnings
VS Code reads skills one folder below .github/skills, .claude/skills or .agents/skills and falls back to the folder name when the name is missing or differs; GitHub's Copilot docs require the exact name SKILL.md.
- Warning
Paths that may not work once the skill is installed: line 141: ../../tools/integrations/ahrefs.md (outside the skill folder), line 141: ../../tools/integrations/semrush.md (outside the skill folder), line 141: ../../tools/integrations/dataforseo.md (outside the skill folder), line 142: ../../tools/integrations/exa.md (outside the skill folder), line 142: ../../tools/integrations/firecrawl.md (outside the skill folder) and 1 more.
