Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

alterlab-recommendation-letters scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/claim_guard.py, scripts/letter_scaffold.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Recommendation Letters — Evidence-Anchored References Written About a Candidate

The faculty task this skill owns is writing about someone else: the letter a professor sends to an admissions committee, a hiring chair, a tenure case, or a fellowship panel. It is the mirror image of alterlab-academic-career, which helps the candidate write their own CV and statements. Here the author is the recommender, the subject is a third party, and the failure mode is not modesty but fabrication — the warm letter full of superlatives that an evaluator cannot act on because nothing is anchored to evidence.

This skill turns a structured dossier (what the recommender actually knows) into a letter whose every strong claim is earned by a specific, checkable example, with specificity and register calibrated to the letter type.

When to Use This Skill

Use this skill when the request is to draft, revise, or evidence-check a letter written about a candidate by a recommender:

  • "Write a recommendation letter for my PhD student applying to postdocs."
  • "I'm a reference for a colleague's faculty application — draft the letter."
  • "I've been asked for an external review letter for X's tenure case."
  • "Draft a fellowship / award nomination for my mentee."
  • "Here's my draft letter — flag anything I claim without backing it up."
  • "Make this reference letter more specific; it reads like boilerplate."

The skill always treats the recommender as the author of record: it produces a draft for them to verify, edit, sign, and submit, never a letter it claims to send or to vouch for on its own authority.

Does NOT Trigger

The request is really… Route to Why
The candidate's own CV, research/teaching statement, cover letter, tenure dossier, promotion narrative alterlab-academic-career Self-authored career documents, not a third party writing about the candidate
A peer-review report judging a manuscript's quality with an accept/revise/reject verdict alterlab-peer-review Editorial quality judgment of a paper, not a personal reference for a person
A structured peer review of a full manuscript (core-pipeline reviewer) alterlab-paper-reviewer Section-by-section manuscript critique, not a recommendation about a candidate
Türkiye doçentlik eligibility / point computation for an associate-professor case alterlab-docentlik-eligibility ÜAK criteria scoring, not a prose reference letter
Academic-incentive (akademik teşvik) point computation alterlab-akademik-tesvik YÖK incentive points, not a letter
Checking that the citations in a letter or dossier actually exist alterlab-citation-verifier Bibliographic existence verification, not letter-claim evidence-anchoring
Designing a course, rubric, or syllabus for the student alterlab-teaching-design Course/instructional design, not a reference about the student
Writing a grant proposal or post-award report alterlab-research-grants / alterlab-grant-reporting Funding documents, not personal references

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
