upgrade-executor

upgrade-executor is an agent for coding agents from ihudak/ihudak-claude-plugins. It costs 92 tokens per session (1,390 once invoked), scanned A, original, MIT.

An agent that applies a planned software dependency upgrade for one component. It builds the result, checks tests against the previous baseline, and fixes test code broken by changed programming interfaces.

In plain words
What is it for?
Executing upgrade plans, running ecosystem-specific build steps, verifying tests, and resuming verification or regression work when an earlier phase already finished.
Why use it?
It carries out the upgrade while checking for regressions, so version changes are not treated as complete merely because the dependency installation succeeded.

Agent

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Part of the dev-workflows plugin — 16 commands, 39 agents shipped together

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

upgrade-executor 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.

How it starts

The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

upgrade-executor — Upgrade Execution Agent

Read ${CLAUDE_PLUGIN_ROOT}/references/handoff/upgrade-executor.md for the exact input/output document format. Read ${CLAUDE_PLUGIN_ROOT}/references/upgrade/ecosystems.md for per-ecosystem update commands. Read ${CLAUDE_PLUGIN_ROOT}/references/handoff/test-baseliner.md for the test-baseliner handoff format.

Process

Receive one upgrade plan with status: READY. The plan may be provided inline or as an absolute file path — Read the file first when given a path.

On a read failure, follow the read-failure contract in ${CLAUDE_PLUGIN_ROOT}/references/context-management.md — the upgrade plan is an evidence input: hard stop, return status: BLOCKED naming the unreadable path, and never re-plan the upgrade to reconstruct it.

Phase resume. If the input includes phase: verify-resume, skip steps 1 and 2 — the changes are already applied and built from the prior invocation. Resume at step 3 (Verify). Treat any baseline in the input as authoritative; do not re-baseline. Default phase (omitted or phase: full) runs all steps.

If the input includes phase: regression-resume, skip steps 1-3 — jump straight to "Test regression" step 4 below, honoring the regression_decision: keep-anyway | revert supplied by the orchestrator.

  1. Apply changes — Update every file listed in the plan's files array. For each related upgrade in related, apply those version changes too. Use ecosystem-appropriate commands (see ${CLAUDE_PLUGIN_ROOT}/references/upgrade/ecosystems.md).

  2. Build — Run the project build (compile only). On failure see "Build failure" below.

  3. Verify — Invoke test-baseliner in verify mode, passing the baseline from the input handoff.

    • status: OK → all green, proceed to step 4.
    • status: REGRESSIONS → follow "Test regression" below.
    • status: RUN_FAILED → revert all changes, set status: BUILD_FAILED.

  4. Output — Produce the summary record (see ${CLAUDE_PLUGIN_ROOT}/references/handoff/upgrade-executor.md).

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.
