What it does

Supercompress is an agent skill from Supercompress/Supercompress. Always-on context compression for OpenClaw. Compress bulky tool dumps / files / logs via MCP compresscontext; never compress the user's ask. Prefer session-scoped inbox/<sessionId/latest.md digests.

Its SKILL.md is about 370 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Productivity & Automation, covering Email management and LLM cost and token optimization. It works with Model Context Protocol. The repository describes itself as: Query-aware context compression for LLMs and coding agents. Cut ~65% of input tokens. The licence is MIT.

When your agent uses it

  • Tasks that involve Email management
  • Tasks that involve LLM cost and token optimization

Example prompts

  • “/supercompress”

Workflow steps

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

  1. If inbox//latest.md exists for this session, Read it first — session digest (ask is unchanged).
  2. Else call MCP compress_context with context= and query=. Prefer the returned digest over raw dumps.
  3. The SuperCompress OpenClaw plugin also auto-compresses large tool results into the session inbox when installed.
  4. If compress_context fails with account-not-linked, call connect_account once, then retry.

What it can do on your machine

Read from SKILL.md and the folder at commit 1b76c6f. 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

Supercompress loads about 366 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 152 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~366

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.

Always-on context compression for OpenClaw. Compress bulky tool dumps / files / logs via MCP compress_context; never compress the user's ask. Prefer session-scoped inbox/<sessionId>/latest.md digests.

SuperCompress (OpenClaw)

Auto (Headroom-parity): compress every new bulky context dump; when rolling session memory gets large, compact it. Never compress the user's ask/query. Skip already-seen chunks.

Inbox digests are session-scoped under $SUPERCOMPRESS_CONFIG_DIR/inbox/<sessionId>/ (default ~/.supercompress/inbox/<sessionId>/) so sessions never cross-contaminate.

When to use

After large tool results, file reads, diffs, logs, scrapes, or pasted blobs — anything that is not the current user question.

How

  1. If inbox/<sessionId>/latest.md exists for this session, Read it first — session digest (ask is unchanged).
  2. Else call MCP compress_context with context=<new dump only> and query=<user ask>. Prefer the returned digest over raw dumps.
  3. The SuperCompress OpenClaw plugin also auto-compresses large tool results into the session inbox when installed.
  4. If compress_context fails with account-not-linked, call connect_account once, then retry.

Do not

  • Compress the user's question / instructions.
  • Re-paste raw tool dumps after a digest exists.
  • Read another session's inbox file.
  • Require provider API-key proxy mode — normal login is fine.
