What it does

Academic Letter Architect is an agent skill from lyndonkl/claude. Guides the creation of evidence-based academic recommendation letters, reference letters, and award nominations that combine concrete examples, meaningful comparisons, and genuine enthusiasm. Use when writing recommendation letters for students, postdocs, or colleagues, or when user mentions recommendation letter, reference, nomination, letter of support, endorsement, or needs help with strong advocacy and comparative statements.

Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files (for example `resources/evaluators/rubric_academic_letter.json`, `resources/methodology.md` and `resources/template.md`).

It sits in AI & LLM Engineering. The repository describes itself as: Agents, skills and anything else to use with claude.

When your agent uses it

  • Writing recommendation letters for students
  • User mentions recommendation letter
  • Letter of support
  • Needs help with strong advocacy and comparative statements

Example prompts

  • “Use the academic-letter-architect skill to guide the creation of evidence-based academic recommendation letters, reference letters, and award…”
  • “/academic-letter-architect”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Truthfulness: Only write what you genuinely believe. Dishonest letters harm candidates and your reputation.
  2. Evidence-based: Every claim should have a supporting example. "Smart" means nothing without evidence.
  3. Appropriate comparison: Compare to relevant reference class (other postdocs, not all scientists ever).
  4. Match content to opportunity: Emphasize research for academic jobs, practical skills for industry.
  5. Candidate voice preservation: Reflect the candidate's actual achievements, not fabricated ones.
  6. Cultural awareness: US letters are more superlative than other cultures. Calibrate appropriately.

What it can do on your machine

Read from SKILL.md and the folder at commit 4acc337. 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.

    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

Academic Letter Architect loads about 2.5k tokens when it runs. Until then it costs about 115 tokens; SKILL.md has 956 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~115
When it runs · the whole SKILL.md, loaded when a task matches
~2.5k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 956 words (~2,529 tokens).
