What it does

Triangulation is an agent skill from ai-analyst-lab/ai-analyst. Analyze one decision through independent methods or sources, compare the paths, and reconcile disagreement. Use when a novel analysis needs corroboration and no single answer key is available.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Creative writing and fiction. The repository describes itself as: AI Product Analyst — Claude Code-powered data analysis toolkit. The licence is MIT.

When your agent uses it

  • A novel analysis needs corroboration and no single answer key is available
  • Tasks that involve Creative writing and fiction

Example prompts

  • “/triangulation”

What it can do on your machine

Read from SKILL.md and the folder at commit 52c0744. 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

Triangulation loads about 642 tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 338 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~642

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.

Triangulate an analysis

Select paths deliberately

First determine what the available data can support. Choose paths that differ in method, source, population, assumptions, or counterfactual. Opening more sessions that repeat the same method is not meaningful triangulation.

Each path must work without seeing the other paths' conclusions. Record:

  • path ID;
  • method;
  • source;
  • population;
  • assumptions;
  • direction as yes, no, or unclear; and
  • the evidence supporting that direction.

For a live analysis, use three paths unless the user requests another number. Inspect the available data first, then propose three methods that answer different parts of the decision and rely on meaningfully different assumptions. Aim for a 400-word proposal and never exceed 500 words. Keep each path narrow enough to complete with no more than two read-only queries and a narrative of no more than 250 words unless the user asks for a deeper analysis. Compact SQL and result tables do not count toward the narrative limit.

After the user approves the methods, run the three paths in fresh subagents in parallel. Give each subagent the complete original task and terminology constraints, its assigned method, the approved data source, the two-query and 250-word narrative limits, and the required output fields. Do not paraphrase or omit user constraints when delegating. Do not show one path another path's work.

Save each path separately under working/triangulation/<slug>/, then save a comparison that shows the method, question answered, assumptions, important evidence, direction, and limitations for every path.

Compare the paths

Use helpers.evals.triangulation.build_grid to assemble the comparison. Run each genuinely different path once. A second full round is not required. If one path is surprising or disputed, rerun only that path in a fresh context to determine whether the difference is run variation or a persistent methodological disagreement.

When paths disagree, locate the difference in their populations, assumptions, sources, or counterfactuals. Reconcile the difference only when the evidence supports it. Otherwise preserve the disagreement and escalate it.

When paths agree, state what their independence adds and what it still cannot establish. Convergence is not proof of correctness.
