What it does
Compare Cohorts is an agent skill from microsoft/power-platform-skills, published by the product's own GitHub organization. Use when comparing process cohorts, departments, periods or before-and-after results under matched definitions.
Its SKILL.md is about 920 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: A plugin marketplace for GitHub Copilot and other AI agents that provides Power Platform development plugins, including reusable skills, agents, and commands for building and… The licence is MIT.
When your agent uses it
- Comparing process cohorts
- Before-and-after results under matched definitions
Example prompts
- “/compare-cohorts”
Requirements
- Pre-approved tools (allowed-tools): Read, AskUserQuestion
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Copy baseline F twice. For attribute cohorts append
- get_process_overall_metrics_v2 {S,filterOptions:F_A} ->
- Only if a grouped explanation is needed and statistics is advertised, make a matched pair
What it can do on your machine
Read from SKILL.md and the folder at commit 7d6b845. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadAskUserQuestion
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
Compare Cohorts loads about 922 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 403 words of instructions outside code blocks.
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.

Matched cohort comparisons
Use the shared contract and filters/units. Fix the outcome definition/provenance, metric, aggregation, units, timezone and one selector S. Freeze the user's agreed baseline F, separately from current exploratory filters. Reuse metadata versions and exact typed cohort values. Use the investigation method for findings/status.
Ordered trace
- Copy baseline F twice. For attribute cohorts append
{attributeName:A,dataType:T,attributeValues:[X],isInclusive:true}toattributeValueFiltersfor A's cohort value, and the same shape with Y for B. Preserve other agreed baseline conditions; retain rework restrictions only if part of that baseline. Do not leak an exploratory/outcome-only subset into a full-population comparison. Change only the intended cohort condition. If values are unknown, requestget_attribute_values_v2 {S,attributeName:A,itemsPerPage:20,itemsToSkip:0,filterOptions:F}; it returns values, not frequencies. get_process_overall_metrics_v2 {S,filterOptions:F_A}->get_process_overall_metrics_v2 {S,filterOptions:F_B}. Nometrics,groupByor aggregation parameter exists. Use the same returned metric definitions; nativeCaseDuration/CaseWaitingTimeare means.- Only if a grouped explanation is needed and statistics is advertised, make a matched pair:
get_attribute_statistics {S,attributeName:A,filterOptions:F_A,itemsPerPage:5,itemsToSkip:0,metricToSortBy:"TotalDuration",sortOrder:"Descending"}, then exactly the same call with F_B. Do not treat independent top-five pages as a complete aligned population.
Continue relevant value/group pages or matched follow-ups when needed, without fixed call quotas. Stop at sufficient evidence, no new information or a capability/error boundary; no blind sweeps. Do not create views or use two inclusive timeframes in one query as an A/B comparison.
Show full SKILL.md (188 more words)Show less
Time and reproducibility
For periods, change only one explicit timeframeFilters start/end pair in each copied F.
Case windows mean Contained, not cases Started/Completed/Intersecting or all events during the period.
If completed-only membership including earlier starts is essential, stop/reframe or route
to derive-metric/a user-confirmed existing matching view. Never invent a date-mode field
or promise unknown end-boundary behavior.
If refresh is reported or reproducibility is at risk, recheck details. Changed PV/PMV invalidates the pair: mark inconclusive, stop or deliberately rerun both, not just the second. Process selection resolves latest; no direct version selector or atomic comparison snapshot exists. Views pin version context but their configuration is mutable/cached.
Report A/B counts, mean metrics, absolute delta and relative change only for a nonzero baseline. Empty cohorts mean insufficient evidence, not zero duration/infinite improvement. State scope/version and unmatched-group coverage; at most five headline rows. Recorded means do not establish closure, equal maturity or complete lifecycles. Report those as unknown unless supported; qualify the comparison, not an assumed causal improvement. Retain baseline/cohort filters, evidence references, status and alternatives. Overlapping groups cannot be added as unique-case totals. Object-centric comparisons belong in analyze-objects, not case-filter fallbacks.
