ase-task-condense

ase-task-condense is a skill for Claude Code, Codex from rse/ase. It costs 56 tokens per session (2,054 once invoked), scanned A, original, Apache-2.0.

A tool that shortens a task plan while preserving its structure and meaning.

In plain words
What is it for?
Use it to compress a plan, specification, or task description without changing its content.
Why use it?
It reduces the amount of text needed to read and maintain a plan.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ase-task-condense scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Procedure

  1. Determine Task:

    1. Set initially, with any leading and trailing whitespace stripped. Inherit the always existing from the current context. Inherit the always existing from the current context. Do not output anything.

    2. React on task id:

  2. Determine Operation:

    1. Determine the current task plan content:

      Set (remember the loaded plan content for the strictly-shorter check in step 3).

  3. Condense Task Plan:

    1. Apply the condense ruleset to , producing a shorter . The goal is to make the plan require as little reading as possible while all semantics remain fully preserved and unchanged. Honor the following ruleset strictly:

      1. Preserve-exactly (never alter): the plan structure (the frontmatter block with its Id:, Created:, Modified:, Status:, Properties:, and Kind: keys, the headings #/##, all three ## CONTEXT, ## CHANGES, and ## VERIFICATION sections, and the - **<aspect/>**: bullet labels), all code spans and code blocks, technical terms, file paths, identifiers, numbers, severities (LOW/MEDIUM/HIGH/ACCEPTED), and the *<aspect/>* emphasis highlighting convention.

      2. Compress free-text only (the **WHAT**/**WHY** prose and each bullet's <specification/> text):

        • Drop filler ("just", "really", "basically", "simply"), pleasantries, and hedging ("I think", "maybe", "perhaps").
        • Use shorter synonyms and common abbreviations.
        • Use for causality and - for short subsequent facts.
        • Drop articles ("a", "an", "the") and replace conjunctions with short separate clauses where this shortens the text without introducing ambiguity.
        • Re-wrap the shortened free-text to the ~100-character- per-line convention of the plan , but never break a line inside an inline code span.
        • Merge genuinely-redundant bullets (the same aspect restated) and drop pure duplication -- but only when truly redundant; never lose a distinct aspect.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
