At a glance

Help the user remove a stored fact using Codewhale's Context Lens when they ask to forget or delete a memory.

  • Works in 3 steps: Identify the fact the user wants… → Direct the user to select that fact in… → State that nothing has been deleted…
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Forget is an agent skill from codewhale-hq/Codewhale. Help the user remove a stored fact using Codewhale's Context Lens when they ask to forget or delete a memory.

Its SKILL.md is about 290 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `SKILL.generation-13.md`).

The repository describes itself as: Open-source coding agent for your terminal, built in Rust and on a journey of continuous community improvement. Issues and PRs welcome. The licence is MIT.

Example prompts

  • “/forget”

Workflow steps

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

  1. Identify the fact the user wants removed, quoting stored text only when it
  2. Direct the user to select that fact in Context Lens and use its forget
  3. State that nothing has been deleted until the control reports completion.

What it can do on your machine

Read from SKILL.md and the folder at commit fead51e. 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

Forget loads about 289 tokens when it runs. Until then it costs about 29 tokens; SKILL.md has 160 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~29
When it runs · the whole SKILL.md, loaded when a task matches
~289

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.

Forget

Forgetting belongs to the user's Context Lens controls. The remember tool supports append and revise candidates only; it cannot submit a deletion. Do not invent a removal proposal or claim one is pending.

  1. Identify the fact the user wants removed, quoting stored text only when it is actually available. Do not claim a fact exists merely because it was mentioned in the conversation.
  2. Direct the user to select that fact in Context Lens and use its forget action. If the host has no Context Lens, say that this action is unavailable there; do not substitute direct edits to memory files or a fake tool call.
  3. State that nothing has been deleted until the control reports completion. Verify removal when the host exposes that evidence; otherwise attribute the confirmation to the user.

Do not overwrite memory with an empty or contradictory note to simulate deletion. Removing stored memory does not erase the existing conversation or its history.
