  • Tasks that involve Recruiting and HR

What it does

Ksa Taxonomy is an agent skill from revfactory/harness-100. A specialized skill for building KSA (Knowledge, Skill, Ability) taxonomies in job analysis and mapping them to NCS/ONET standards. Used by the job-analyst and competency-architect agents when writing job descriptions and systematically classifying competencies. Automatically applied in contexts involving 'KSA analysis,' 'job description,' 'NCS,' 'ONET,' 'task analysis,' or 'competency classification system.' Note: actual NCS system access or HR system data integration is outside the scope of this skill.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Business, Finance & HR, covering Recruiting and HR and Data pipelines and ETL. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Recruiting and HR
  • Tasks that involve Data pipelines and ETL

Example prompts

  • “KSA analysis,”
  • “job description,”
  • “task analysis,”
  • “/ksa-taxonomy”

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ksa Taxonomy loads about 1.3k tokens when it runs. Until then it costs about 131 tokens; SKILL.md has 329 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~131
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
