askit-deprecate

askit-deprecate is a skill for Claude Code from product-on-purpose/agent-skills-toolkit. It costs 51 tokens per session (491 once invoked), scanned A, original, Apache-2.0.

A component life-cycle tool for marking a software component as deprecated, recording its replacement and planned removal version, and checking that its deprecation details are complete. Deprecated means the component should no longer be used for new work but remains available for a transition period.

In plain words
What is it for?
Use it when retiring a component, naming the replacement, setting a target version for removal, or checking that the deprecation record follows the project's policy.
Why use it?
It prevents a component from disappearing without warning and gives users clear migration information. It also checks that deprecated components continue to meet validation rules until their removal version.

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

askit-deprecate 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 11d 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.

What it actually says

askit-deprecate

Purpose

Manage a component's end-of-life cleanly. Two modes: deprecate marks a component status: deprecated and records its replacement (deprecated-by) and the version it will be removed in (remove-in), per Standard sec 3.7 / 7.5; check runs the G6 deprecation check (the contract is complete) and confirms a deprecated component still validates until its remove-in version, so consumers get a migration window rather than a sudden break. Policy and the lifecycle are in references/deprecation-policy.md.

When to use

When deprecating a component, recording its replacement, or checking that deprecated components still validate before their removal version.

deprecate mode

  1. Set the component's status to deprecated in library.json (and the component frontmatter metadata.status).
  2. Record deprecated-by (the replacement component) and remove-in (the target plugin version for removal).
  3. Point users at the replacement in the component's description or body; do not delete it yet.

check mode

  1. Run node scripts/check.mjs (the aggregate gate, which includes the G6 deprecation check): every deprecated component declares deprecated-by + remove-in, and no component carries an invalid status.
  2. Confirm each deprecated component still passes its tier checks until remove-in (a deprecated component must keep validating during the migration window).

Scope

The G6 deprecation check enforces the contract deterministically; this skill is the front door and the policy. Actual removal at the remove-in version is a release-time action driven by askit-release (and recorded in the CHANGELOG). Deprecation is the Gold G6 baseline; a dedicated removal-automation skill is roadmap (the policy and frontmatter handling are what v1 requires).

Changes

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.
