What it does

Ma Network Meta Analysis is an agent skill from htlin222/meta-pipe. Run network meta-analysis in R with gemtc (Bayesian, primary) and netmeta (frequentist, sensitivity), generate network graphs, league tables, SUCRA rankings, inconsistency diagnostics, and CINeMA GRADE assessment. Use when comparing ≥3 treatments with direct and indirect evidence.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 27 other files, including scripts, reference files and assets (for example `references/cnma-guide.md`, `references/nma-assumptions.md` and `references/nma-completion-checklist.md`).

It sits in Research & Science. The repository describes itself as: Claude Code-powered end-to-end meta-analysis automation: AI-assisted literature review, screening, extraction, analysis, and manuscript generation for systematic reviews and….

When your agent uses it

  • Comparing ≥3 treatments with direct and indirect evidence

Example prompts

  • “/ma-network-meta-analysis”

Workflow steps

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

  1. Initialize renv in 06_analysis/ and install gemtc, rjags, netmeta, meta, metafor, ggplot2, gt.
  2. Copy NMA R templates from ma-network-meta-analysis/assets/r/ into 06_analysis/ and adapt to study schema.
  3. Prepare data in contrast-based or arm-based format for gemtc.
  4. Verify network connectivity with netconnection() and visualize geometry with netgraph().
  5. Fit Bayesian NMA with gemtc (primary): consistency model, random effects, empirical priors (Turner/Rhodes) or vague priors. Check…
  6. Assess inconsistency: node-splitting (mtc.nodesplit()), unrelated mean effects model, and design decomposition via netmeta.
  7. Generate forest plots from posterior distributions at 300 DPI.
  8. Compute SUCRA rankings and rankograms from posterior samples.
  9. Create comparison-adjusted funnel plot.
  10. Run frequentist sensitivity with netmeta(method.tau="REML") — place in supplement.
  11. Export league table (full pairwise comparisons), heatmap, and rankings as gt/PNG at 300 DPI.
  12. Run CINeMA assessment (GRADE for NMA) — rate certainty of each comparison.

What it can do on your machine

Read from SKILL.md and the folder at commit 5c5c3f0. 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

    Ships 1 file in scripts/ (R, from the files we listed), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • cinema.ispm.unibe.ch

    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

Ma Network Meta Analysis loads about 2k tokens when it runs, and up to ~22k if it reads all its reference files. Until then it costs about 77 tokens; SKILL.md has 779 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~77
When it runs · the whole SKILL.md, loaded when a task matches
~2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~22k

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); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 779 words (~2,036 tokens).

“Analyze extracted data comparing three or more treatments using network meta-analysis methods. Primary analysis is Bayesian (gemtc) per 2026 NICE/WHO/Cochrane methodological consensus. Frequentist sensitivity (netmeta) goes in supplement.”
