What it does

🐉 To be used when you have a folder containing N Post Mortem files. This will help crunch data and maintain/update a POMO_AGGREGATED.md file.

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

--- name: postmortem-aggregator metadata: author: Riccardo Carlesso version: 0.0.1 status: draft # CHANGELOG # 10mar26 v0.0.1 Initial idea dump # /CHANGELOG # TODO -> refine this base idea # The base idea is to do what I've done with numerous customers # 1. Enforce a JSON/FrontMatter schema for the PostMortem, with at least date started, date ended, datetime detected, product area, and # 2. This skill must have in input a folder with 3+ PoMos # 3. => Crates a small graph / statistics of "How many bad minutes you had this year" and create a few graphs, and tables and document in a `pomo-statistics.md` # TODO(ricc): ensure to patch the PoMo creator to also add a FrontMatter to make life easier here. Also add a PoMoGenerator version like 1.1 to be used later on. Damn I didn't envision cross-markdown-version-dependencies until today! :) # TODO(ricc/Gemini): add scripts to create the CSV here, and also to create graphs with the numbers given. Script should be able to work on test data. ---

23* If the pomos are local in a folder, use those.
24* If they're external, create a new folder called YYYYMMDD_POSTMORTEMS/ and copy their MD version there. This might lose information, but ensure the relevant info is transported here, locally. You could run the "postmortem generator" skill on a locally curled page.
25* If there is ONE, refuse to run this.
26* If there is 2-3, suggest the user it's worth using a plurality of these.

28## Action

30Check all the Post Mortems in the folder and identify these informations:
31
321. Timestamp of outage start.
331. Timestamp of outage identified by human and being worked on (if available).
341. Timestamp of first Mitigation going into place (if available)
351. Timestamp of outage end.
361. Product used (eg Cloud, Youtube). Products could have a taxonomy (eg Cloud::GCE::PersistentDisk, Youtube::Playlists)
371. RootCause class (HUMAN_ERROR, CONFIG_CHANGE, EXTERNAL_CAUSE, ..).
381. Outage size, how bad it was (TEST, NEGLIGIBLE, SMALL, MEDIUM, BIG, CATASTROPHIC).

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈290
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
660
on trigger
The instruction body, read only when the skill fires.
0.47%
of a 200k window
Ten skills this size would take about 5% of the window before you open a file.
050k100k150k200k context window

950 tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Small enough to keep loaded permanently without thinking about it.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

1 file, 3.8 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md3.8 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 1 file you can review in full before installing. The Apache-2.0 licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# Identify the PoMos · 950 tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/identify-the-pomos/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/identify-the-pomos" ] && { [ ! -e .claude/skills/identify-the-pomos ] || { mv .claude/skills/identify-the-pomos "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/identify-the-pomos" .claude/skills/ && echo "Installed .claude/skills/identify-the-pomos"
On Windows, or any OS with Node 20+
npx mcprush@latest skill add gemini-cli-extensions/identify-the-pomos

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/identify-the-pomos/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/identify-the-pomos/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/identify-the-pomos" ] && { [ ! -e ~/.claude/skills/identify-the-pomos ] || { mv ~/.claude/skills/identify-the-pomos "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/identify-the-pomos" ~/.claude/skills/ && echo "Installed ~/.claude/skills/identify-the-pomos" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/identify-the-pomos/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where. It appears as postmortem-aggregator in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, identify-the-pomos.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

v0.0.1 is what is on the shelf; no release here carries a date. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

v0.0.1
  • No earlier releases have been published to the marketplace.
Pinning

The install command always fetches the release that is current the day you run it — v0.0.1 today — and cannot ask for an earlier one. The copy on your disk does not change until you run it again.
