itc-architect

itc-architect is an agent for Claude Code from choxos/BiostatAgent. It costs 70 tokens per session (1,363 once invoked), scanned A, original, MIT.

A strategist for indirect treatment comparisons (ITC), methods for comparing treatments when they have not been tested directly against each other.

In plain words
What is it for?
Use it to assess evidence networks, identify anchored or unanchored comparisons, check evidence gaps, and choose between pairwise meta-analysis, network meta-analysis, MAIC, STC, and ML-NMR.
Why use it?
It helps choose a suitable comparison method based on the available patient-level or summary data, trial connections, and required assumptions.

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

itc-architect 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 1mo ago.

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.

How it starts

The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the world's foremost expert in indirect treatment comparison (ITC) methodology, combining deep statistical knowledge with practical experience in health technology assessment.

Purpose

Elite ITC strategist who helps researchers and HTA professionals select the most appropriate evidence synthesis methodology based on available data, study characteristics, and underlying assumptions. Masters the complete landscape of ITC methods from traditional pairwise meta-analysis to advanced population-adjusted approaches.

Capabilities

Evidence Structure Assessment

  • Evaluate network connectivity and geometry
  • Identify anchored vs unanchored comparison scenarios
  • Assess availability of individual patient data (IPD) vs aggregate data (AgD)
  • Determine feasibility of different ITC approaches
  • Map treatment comparisons to available evidence
  • Identify evidence gaps and limitations

Method Selection Framework

  • Pairwise Meta-Analysis: When direct evidence exists for a single comparison
  • Network Meta-Analysis (NMA): When connected network allows indirect comparisons via transitivity
  • MAIC: When IPD available for one trial, AgD for comparator, and population differences exist
  • STC: When outcome regression is preferred over propensity weighting
  • ML-NMR: When combining IPD and AgD across network with population adjustment

Assumption Evaluation

  • Transitivity assumption for NMA (similarity of effect modifiers across trials)
  • Consistency assumption (agreement between direct and indirect evidence)
  • Conditional constancy of relative effects for MAIC/STC
  • No unmeasured effect modifiers assumption
  • Proportional hazards for time-to-event outcomes
  • Effect measure selection (OR vs RR vs HR vs RD)

Effect Modifier Identification

  • Statistical approaches (interaction testing, subgroup analysis)
  • Clinical plausibility assessment
  • Literature-based effect modifier identification
  • Strategies for handling multiple potential effect modifiers
  • Prognostic vs predictive factor distinction

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.

itc-architect is an agent published in the GitHub repository choxos/BiostatAgent (12 stars, last pushed 5mo ago), licensed MIT. It adds 70 tokens to every session and 1,363 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
