reliability

reliability is a skill for Claude Code from ai-analyst-lab/ai-analyst-plugin. It costs 93 tokens per session (1,320 once invoked), scanned A, original, MIT.

A repeatability check for analytics answers that runs the same question several independent times and compares the results.

In plain words
What is it for?
Use it to test questions such as retention-rate or performance queries for stability across repeated runs.
Why use it?
It shows whether an answer stays consistent or changes because the question is unclear. Consistency does not prove the answer is correct.

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

reliability 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/reliability_stats.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.

Skill: Reliability check

Purpose

Run one analytics question several independent times and report whether the answer is stable (every run agrees) or drifting (runs disagree because the question is under-defined). Stability is necessary, not sufficient: a wrong query is perfectly stable. This check needs no ground truth.

Invocation

/reliability "<the question>" [N] — default N = 5. Example: /reliability "What's our retention rate?"

How to run it

Step 1 — fire N independent runs

Launch N sub-agents in parallel with the Task/Agent tool (N defaults to 5). They must be genuinely independent: each gets a fresh context and sees ONLY the question, never the other runs' answers. Give each sub-agent exactly this brief:

You are answering one analytics question against the active dataset. Load the normal session context first (knowledge-bootstrap: read .knowledge/active.yaml, then the active dataset's schema.md, quirks.md, and manifest from the local datasets dir). For the metric dictionary and semantic context, first resolve the context dir: read .knowledge/context-source.yaml; if it exists and says source: git, clone or pull the repo it names into .knowledge/.context-cache (checkout the ref, default main) and use the dataset's directory inside that cache; otherwise use .knowledge/datasets/{active}/. Read metrics/index.yaml and semantic/ from the RESOLVED dir, not from any other copy. Do not read .knowledge/reliability/ history before answering. If the metric you're asked about is defined in the dictionary, use that definition exactly. If it is not, decide for yourself how best to define and measure it. Query the real data through the session's active data connection (the mounted files or the connected warehouse). Answer the question: "". Then return ONLY this block: headline: <the single number you'd report> measured: <one line: numerator, denominator, grain, window, any filter> definition_source: <"metric dictionary" if you used a defined metric, else "my own choice">

Changes

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.

reliability is a skill published in the GitHub repository ai-analyst-lab/ai-analyst-plugin (33 stars, last pushed 1mo ago), licensed MIT. It adds 93 tokens to every session and 1,320 once invoked, about $0.0004 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.
