What it does

Recall is an agent skill from AgentToolkit/altk-evolve. Must be used at the start of any non-trivial task involving code changes, debugging, repo exploration, file inspection, or environment/tooling investigation to surface stored guidance before analysis or tool use.

Its SKILL.md is about 950 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/retrieve_entities.py`).

It sits in Development. The repository describes itself as: Self improving agents through iterations. The licence is Apache-2.0.

When your agent uses it

  • Development work in your project

Example prompts

  • “/recall”

Requirements

  • Python 3

Workflow steps

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

  1. If a manifest has already been injected for this turn, use it to pick which entity files to open. Otherwise inspect…
  2. Read each matching entity file that appears relevant.
  3. Summarize the applicable guidance in your own words before proceeding.
  4. If no relevant entities exist, state that explicitly before proceeding.

What it can do on your machine

Read from SKILL.md and the folder at commit 9e5bb56. 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

    Ships 1 file in scripts/ (Python), which the agent can run.

    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

Recall loads about 950 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 379 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~950

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); the scripts in this folder are not scanned.

Entity Retrieval

Overview

This skill loads relevant stored Evolve entities into the current turn before substantive work begins.

Use this skill first whenever the task involves:

  • code changes
  • debugging
  • code review
  • repo exploration
  • file inspection
  • environment/tooling investigation

Skip only for trivial conversational requests with no local context.

Required Action

Before any non-trivial local work, you must complete the recall workflow below. Reading this SKILL.md alone does not satisfy the skill.

Completion Rule

Do not proceed to other analysis or tool use until all steps below are complete.

  1. If a manifest has already been injected for this turn, use it to pick which entity files to open. Otherwise inspect ${EVOLVE_DIR:-.evolve}/entities/ and ${EVOLVE_DIR:-.evolve}/public/ for guidance relevant to the current task.
  2. Read each matching entity file that appears relevant.
  3. Summarize the applicable guidance in your own words before proceeding.
  4. If no relevant entities exist, state that explicitly before proceeding.
Required Visible Completion Note

Before moving on, produce an explicit completion note in your reasoning or user update using one of these forms:

  • Recall complete: searched ${EVOLVE_DIR:-.evolve}/entities/, read <files>, applicable guidance: <summary>
  • Recall complete: searched ${EVOLVE_DIR:-.evolve}/entities/, no relevant entities found
Minimum Acceptable Procedure
  1. List or search files under ${EVOLVE_DIR:-.evolve}/entities/ and ${EVOLVE_DIR:-.evolve}/public/ (or read the injected manifest if one is present).
  2. Identify candidate entities relevant to the task.
  3. Open and read those entity files.
  4. Summarize what applies, or state that nothing applies.
Show full SKILL.md (144 more words)Show less
Failure Conditions

The skill is not complete if any of the following are true:

  • You only read this SKILL.md
  • You did not inspect ${EVOLVE_DIR:-.evolve}/entities/
  • You did not read the relevant entity files
  • You proceeded without stating whether guidance was found

How It Works

  1. The Claw-code PreToolUse hook fires before each tool call.
  2. The helper script reads tool input from stdin (best-effort, ignored beyond logging).
  3. It emits a minimal manifest from ${EVOLVE_DIR:-.evolve}/entities/ and ${EVOLVE_DIR:-.evolve}/public/ containing only path, type, and trigger.
  4. Claw-code uses that manifest to decide which full entity files to read on demand.
  5. If the hook is not active, this skill remains the full manual fallback: inspect the entity files directly, read the relevant ones, and summarize what applies.

Entities Storage

text
.evolve/entities/
  guideline/
    use-context-managers-for-file-operations.md   <- private
  subscribed/
    memory/                                       <- write-scope clone (publishes land here)
      guideline/
        my-published-guideline.md
    alice/                                        <- read-scope clone
      guideline/
        alice-guideline.md                        <- annotated [from: alice]

Automatic hook output is manifest-first. Each manifest entry contains only:

json
{"path": ".evolve/entities/guideline/use-context-managers-for-file-operations.md", "type": "guideline", "trigger": "When processing files or managing resources"}

Each file still uses markdown with YAML frontmatter:

markdown
---
type: guideline
trigger: When processing files or managing resources
---

Use context managers for file operations

Recall is an agent skill from AgentToolkit/altk-evolve. Must be used at the start of any non-trivial task involving code changes, debugging, repo exploration, file inspection, or environment/tooling investigation to surface stored guidance before analysis or tool use.

When should I use Recall?

Recall fits situations like: development work in your project.

How do I install Recall in Claude Code?

Run `npx skills add AgentToolkit/altk-evolve --skill recall -a claude-code`. Or copy the skill folder (platform-integrations/claw-code/plugins/evolve-lite/skills/evolve-lite/recall in AgentToolkit/altk-evolve) into .claude/skills/recall in your project. Claude Code loads it when a task matches its description.

How do I install Recall in Codex?

Run `npx skills add AgentToolkit/altk-evolve --skill recall -a codex`. Or copy the skill folder (platform-integrations/claw-code/plugins/evolve-lite/skills/evolve-lite/recall in AgentToolkit/altk-evolve) into .agents/skills/recall in your project. Codex loads it when a task matches its description.

Can I use Recall in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add AgentToolkit/altk-evolve --skill recall -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/recall, .gemini/skills/recall, .github/skills/recall and .opencode/skills/recall in your project.

What does Recall need to run?

Going by SKILL.md and its folder, Recall needs Python for the scripts in its folder. Our summary lists: Python 3.

Does Recall access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Recall safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Recall use?

Recall is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Recall use?

About 950 tokens (SKILL.md is roughly 3.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Recall?

Skills that share tags, products or a category with Recall: Trellis Session Insight (mindfold-ai/Trellis, 15k stars), Openspec Verify Change (Fission-AI/OpenSpec, 71k stars), Warp Factory Files (warpdotdev/warp, 65k stars) and Migrate Core Code to Submodules (tinyhumansai/openhuman, 41k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
