At a glance

Read whenever part of a program must run as several separate copies, each under its own id, even with ONE user: a session per chat, a sandbox per job, a workspace per document, a bot per customer.

  • Works in 3 steps: every run for an instance writes a… → a Cron in the program reads the… → the limit is the user's choice: ask them…
  • SKILL.md covers What you mark, Routes stay shared, Which instance a run is for and Starting, stopping and ending…, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Weft Instances is an agent skill from WeaveMindAI/weft. Read whenever part of a program must run as several separate copies, each under its own id, even with ONE user: a session per chat, a sandbox per job, a workspace per document, a bot per customer. @perinstance (a container each), @instancefilled (a value each, a connection included), which instance a run is for, the route shape that works (shared routes, the instance picked per call), instance tokens, costs, starting and stopping one instance's containers, and giving every instance an end. When the copies belong…

Its SKILL.md is about 4.8k 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 programming language for AI orchestrations.

Example prompts

  • “/weft-instances”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. every run for an instance writes a last-used time for it in the program's
  2. a Cron in the program reads the instances idle past a limit and stops
  3. the limit is the user's choice: ask them how long an idle instance lives

What it can do on your machine

Read from SKILL.md and the folder at commit 6e28f31. 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 (its code samples are weft).

    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

Weft Instances loads about 4.8k tokens when it runs. Until then it costs about 146 tokens; SKILL.md has 2,704 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~146
When it runs · the whole SKILL.md, loaded when a task matches
~4.8k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,704 words (~4,824 tokens).

“An [instance] is one separate running copy of part of a program, under an id the program picks (session-7f3a, user-42). You reach for instances whenever the program needs several isolated copies of something, whoever uses them: one sandbox per job…”
