What it does

Reach into past AI conversation history through the `trellis mem` CLI. Use whenever the user asks 'how did we solve X last time', 'have we discussed this before', 'what was the decision on X', 'remind me what we did in this task', '上次怎么解的', '之前讨论过吗', '想起一段对话', or when starting a brainstorm that overlaps prior work, debugging a familiar bug, continuing a task across sessions, or doing a finish-work review. Returns raw past dialogue; decide for the moment whether to update spec, append to task notes, quote inline in the answer, or just internalize.

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.

6# Trellis Session Insight
7
8This skill teaches an AI **how to call trellis mem** — the project's cross-session memory feedstock — and **when reaching for it is the right move**.
9
10It is intentionally a **capability skill, not a workflow**. There is no fixed output file, no required write-back step, no "always run after finish-work" rule. What to do with what mem returns is a judgement call made in the moment of the conversation. The skill exists so the AI knows the capability is there and can decide.
11
12## What trellis mem is
13
14A local CLI that indexes the user's past Claude Code, Codex, Pi Agent, and ZCode conversation logs and lets you list, search, slice by Trellis task boundaries, and dump cleaned dialogue from them. Claude and Codex use ~/.claude/projects/ and ~/.codex/sessions/. Pi uses its default or environment-configured session root, global ~/.pi/agent/settings.json, and the scoped project's .pi/settings.json; relative sessionDir values resolve from the settings file directory. Project-local Pi settings require project-scoped lookup through the current cwd or --cwd. ZCode uses ~/.zcode/cli/db/db.sqlite. OpenCode logs are not yet indexable (provider adapter pending) — when an OpenCode session is the obvious target, surface that limitation rather than guessing.

16Nothing in mem is uploaded. All reads are local.

18## When to reach for it
19
20The bar is "would a senior teammate ask 'didn't we already talk about this?'" — those are the moments. Some concrete patterns:
21
22- **Brainstorm rerun risk.** Starting a new task that touches an area the user has been in before, and you want to check whether a decision was already made — before re-asking the user.
23- **Familiar-bug debugging.** The current bug pattern feels like one the user reported / fixed before. Pulling the relevant past session can save a full debugging loop.
24- **Cross-session continuation.** The user resumes work after a gap and says "where were we" / "继续上次的" without being specific.

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.

≈150
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
4,250
on trigger
The instruction body and 2 supporting files, read only when the skill fires.
2.2%
of a 200k window
Ten skills this size would take about 22% of the window before you open a file.
050k100k150k200k context window

4.4k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

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

3 files, 17.6 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md6.7 kB
  • references/cli-quick-reference.md6.8 kB
  • references/triggering-patterns.md4.1 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 3 files you can review in full before installing.

Install

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

# Trellis Session Insight · 4.4k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/trellis-session-insight/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/trellis-session-insight" ] && { [ ! -e .claude/skills/trellis-session-insight ] || { mv .claude/skills/trellis-session-insight "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/trellis-session-insight" .claude/skills/ && echo "Installed .claude/skills/trellis-session-insight"

npx mcprush@latest skill add anine09/trellis-session-insight

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/trellis-session-insight/ 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/trellis-session-insight/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/trellis-session-insight" ] && { [ ! -e ~/.claude/skills/trellis-session-insight ] || { mv ~/.claude/skills/trellis-session-insight "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/trellis-session-insight" ~/.claude/skills/ && echo "Installed ~/.claude/skills/trellis-session-insight" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/trellis-session-insight/ 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.

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

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.
