Use when writing recommendation letters, reference letters, or award nominations for students, postdocs, or colleagues. Invoke when user mentions recommendation letter, reference, nomination, letter of support, endorsement, or needs help with strong advocacy, comparative statements, or evidence-based character assessment.

resources/evaluators/rubric_academic_letter.jsonresources/methodology.mdresources/template.mdThis skill guides the creation of effective academic recommendation letters that provide evidence-based advocacy. Strong letters combine concrete examples, meaningful comparisons, and genuine enthusiasm to differentiate candidates and support their applications for positions, awards, or opportunities.
Use this skill when:
Trigger phrases: "recommendation letter", "reference letter", "nomination", "write a letter for", "letter of support", "endorse", "vouch for"
Do NOT use for:
career-document-architect)scientific-email-polishing)grant-proposal-assistant)1. Show, don't tell: Concrete examples beat adjectives
2. Comparisons give context: Readers need reference points
3. Enthusiasm is evidence: Tone conveys conviction
4. Address what matters: Match content to opportunity
Copy this checklist and track your progress:
Letter Architect Progress:
- [ ] Step 1: Gather context (candidate, opportunity, relationship)
- [ ] Step 2: Collect evidence (specific examples, achievements)
- [ ] Step 3: Draft opening (credibility, relationship, expectation)
- [ ] Step 4: Build body (evidence paragraphs, comparisons)
- [ ] Step 5: Craft closing (strong endorsement, availability)
- [ ] Step 6: Calibrate tone (enthusiasm level, superlatives)
- [ ] Step 7: Final polish (length, format, signature)
Step 1: Gather Context
Identify: Who is the candidate? What opportunity? Your relationship (advisor, collaborator, instructor)? How long have you known them? In what capacity? See resources/methodology.md for information checklist.
Step 2: Collect Evidence
List 3-5 specific examples demonstrating excellence: Research achievements, intellectual contributions, professional qualities, overcoming challenges. Quantify where possible. See resources/methodology.md for evidence types.
Step 3: Draft Opening
Establish your credibility (position, experience). State relationship to candidate (role, duration, context). Set expectation (strong recommendation signal). See resources/template.md for opening structure.
Step 4: Build Body
Structure evidence into 2-4 paragraphs covering different dimensions (research, intellect, character). Include comparative statements ("top 5%", "best I've seen"). Connect evidence to opportunity requirements. See resources/template.md for paragraph templates.
Step 5: Craft Closing
Provide unambiguous endorsement statement. Offer availability for follow-up. Include professional signature with title/contact. See resources/template.md for closing structure.
Step 6: Calibrate Tone
Ensure enthusiasm matches actual assessment. Check superlative use (too many dilutes impact). Verify letter reads as advocacy, not obligation. See resources/methodology.md for calibration guide.
Step 7: Final Polish
Check length (typically 1-2 pages). Ensure formal formatting. Verify all specific claims are accurate. Validate using resources/evaluators/rubric_academic_letter.json. Minimum standard: Average score ≥ 3.5.
Purpose: Establish credibility and relationship
Elements:
1. Your identity and position
2. How you know the candidate (role, context)
3. Duration of relationship
4. Capacity of observation (direct supervision, collaboration)
5. Clear statement of recommendation
Example: "I am writing to provide my strongest recommendation for Dr. Jane Smith for the position of Assistant Professor. As the Director of the Structural Biology Center at X University, I have had the privilege of working closely with Jane for the past four years, first as her postdoctoral mentor and subsequently as a research collaborator. During this time, I have observed her exceptional scientific abilities, intellectual creativity, and professional maturity firsthand."
Purpose: Provide evidence-based assessment
Paragraph 1: Research/Technical Excellence
Paragraph 2: Intellectual Contributions
Paragraph 3: Professional Qualities
Paragraph 4: Comparative Assessment
Purpose: Summarize and endorse
Elements:
1. Overall assessment statement
2. Specific recommendation (enthusiastic, unambiguous)
3. Prediction for future success
4. Offer of availability for follow-up
5. Professional sign-off
Example: "In summary, Jane is an outstanding scientist with exceptional research abilities, intellectual depth, and professional maturity. I give her my highest and most enthusiastic recommendation without reservation. She will make an excellent faculty member and I am confident she will develop an impactful, independent research program. Please do not hesitate to contact me if you require any additional information."
Highest ("absolutely top"):
Strong ("top tier"):
Moderate ("good but not stellar"):
Lukewarm (damaging):
Strong comparisons:
Weak comparisons (avoid):
| Vague (Weak) | Specific (Strong) |
|---|---|
| "Productive researcher" | "Published 5 first-author papers including 2 in Nature journals" |
| "Good communicator" | "Regularly invited to present at lab meetings and gave a talk at the Gordon Conference" |
| "Works well with others" | "Mentored 3 undergraduate students, all of whom went to top graduate programs" |
| "Technically skilled" | "Independently established our lab's CRISPR screening platform" |
Critical requirements:
Truthfulness: Only write what you genuinely believe. Dishonest letters harm candidates and your reputation.
Evidence-based: Every claim should have a supporting example. "Smart" means nothing without evidence.
Appropriate comparison: Compare to relevant reference class (other postdocs, not all scientists ever).
Match content to opportunity: Emphasize research for academic jobs, practical skills for industry.
Candidate voice preservation: Reflect the candidate's actual achievements, not fabricated ones.
Cultural awareness: US letters are more superlative than other cultures. Calibrate appropriately.

Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
