What it does

Weft Grow is an agent skill from WeaveMindAI/weft. COMMAND, not reference: Grow the program one stage at a time against a real input, seeded runs and frozen examples included. Run this when the user asks for this step by name, optionally naming the stage to grow next or an example to check. The weft- reference skills beside it are things you read; this is a procedure you carry out.

Its SKILL.md is about 730 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.

When your agent uses it

  • Asks for this step by name
  • Optionally naming the stage to grow next
  • An example to check

Example prompts

  • “/weft-grow”

Workflow steps

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

  1. Read weft-sdp, weft-running, weft-debugging (how to read what a run did) and weft-people-in-the-loop (a run waiting on someone, and its…
  2. Read weft tree and weft examples. Checkpoint work you may want back with weft checkpoint start-.
  3. Pick a real input the user cares about; ask if none is available. Grow one stage and run weft validate --file src/main.weft < src/main.weft.
  4. Run that stage: weft run --from '={"port":value}' --target --save --detach, or --group '={"port":value}' for the whole group or included…
  5. During iteration, add --seed to reuse compatible work. --seed-before and --seed-until bound reuse. Verify that the changed nodes ran, then…
  6. When the result is accepted, weft freeze --expect saves the starting parameters and observed outputs, with that node marked for review…
  7. After changes, weft run --detach reruns a relevant example on current code with its saved parameters. Leave out --seed when reviewing the…
  8. A waiting run needs inspection: read its new question and the saved answer before answering through the token. Historical answers and…
  9. Report what ran, what came out, the differences you reviewed and your judgment. Name the next stage and the version in weft tree. If you…

What it can do on your machine

Read from SKILL.md and the folder at commit 350a891. 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.

    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 Grow loads about 732 tokens when it runs. Until then it costs about 86 tokens; SKILL.md has 385 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~86
When it runs · the whole SKILL.md, loaded when a task matches
~732

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 385 words (~732 tokens).

“Run one pass of Sequential Diffusion Programming: inspect the current stage on a real input, preserve an accepted result, then grow the next stage.”
