What it does

Crl Tracker is an agent skill from hh-health-AI/healthcare-equity. This skill should be used when the user asks about "complete response letter", "CRL", "why was it rejected", "refuse to file", "drug shortage", "supply disruption", "who benefits from the shortage", or wants to monitor FDA rejection and supply events across the coverage universe.

Its SKILL.md is about 730 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Synthesis engine for buy-side healthcare equity research. The licence is MIT.

When your agent uses it

  • Asks about complete response letter
  • Why was it rejected
  • Supply disruption
  • Who benefits from the shortage

Example prompts

  • “complete response letter”
  • “why was it rejected”
  • “refuse to file”
  • “/crl-tracker”

Workflow steps

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

  1. Pull recent CRL publications and filter to the coverage universe and to competitors.
  2. Classify the deficiency. The classification is what carries the read-across
  3. Read across to the class. A CRL citing a mechanism-level safety concern raises the

What it can do on your machine

Read from SKILL.md and the folder at commit 6c7bda8. 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

Crl Tracker loads about 728 tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 361 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~73
When it runs · the whole SKILL.md, loaded when a task matches
~728

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.

CRL and shortage tracker

Monitor two event streams that invalidate catalysts and create competitor upside: FDA Complete Response Letters, and drug shortages.

Complete Response Letters

FDA began publishing CRLs in 2025, so the corpus is shallow and skewed to recent and historical batch releases. The absence of a CRL in the dataset is not evidence that no CRL was issued — this is the single most important caveat and belongs in every brief from this skill.

Workflow:

  1. Pull recent CRL publications and filter to the coverage universe and to competitors.
  2. Classify the deficiency. The classification is what carries the read-across:
    • CMC / manufacturing — often resolvable in 6–12 months with a Class 2 resubmission; third-party manufacturing sites can affect several sponsors at once, so check who else uses the plant.
    • Clinical / efficacy — usually requires a new trial. Reset the timeline by years, not quarters, and re-run the probability of success.
    • Safety — may be fatal to the programme in that indication.
    • Inspection-related — a foreign site classified OAI. Look for other sponsors with products at the same site; this is where the cross-read money is.
  3. Read across to the class. A CRL citing a mechanism-level safety concern raises the bar for every competitor with the same mechanism; a CMC CRL says nothing about them.
  4. Hand the timeline reset to a catalyst engine → catalyst-calendar, and the probability revision to readout-handicap.

Drug shortages

  1. Pull /drug/shortages and filter to molecules where the coverage universe has an approved or filed product.
  2. Classify the cause where stated: manufacturing quality, demand increase, discontinuation, raw-material supply.
  3. Identify the beneficiary. A shortage of a sole-source injectable transfers volume to whoever has capacity, and the transfer often persists after resolution because hospital contracts are sticky.
  4. Watch the flip side: a shortage caused by the covered name's own quality problem is a revenue hole plus a warning-letter risk. Cross-check /drug/enforcement and the FDA warning-letter database for the same site.

Not-automatic

A published CRL does not license a conclusion about resubmission timing unless the letter itself states the deficiency type; a shortage listing does not license a market- share conclusion without capacity evidence from the beneficiary's disclosures.
