subagent-driven-change

subagent-driven-change is a skill for Claude Code, Codex from jsuvic/agent-profile. It costs 29 tokens per session (2,042 once invoked), scanned A, original, Apache-2.0.

A workflow for delegating a bounded coding change to helper agents and then reviewing the result independently.

In plain words
What is it for?
Use it when a task has a clear specification, acceptance criteria, owned files, and expected tests, with separate agents for implementation and review.
Why use it?
It separates implementation from checks that confirm the work matches the request, remains good quality, and carries acceptable risk.

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

subagent-driven-change 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 1mo 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.

Subagent-Driven Change

Preconditions

Use this workflow only when the task has a clear spec, acceptance criteria, and file ownership. Keep tightly coupled or architectural decisions in the parent session unless the user explicitly asks for delegation.

Required subagents: implementer, spec-reviewer, code-quality-reviewer, and change-risk-reviewer.

Fresh Context

Each subagent prompt must include the full task text, relevant spec excerpts, non-goals, acceptance criteria, file ownership, constraints, expected tests, and any command limits. Do not rely on hidden chat history or a previous subagent's memory.

Flow

  1. Dispatch implementer with one bounded task and the complete context it needs.
  2. If implementer returns BLOCKED or NEEDS_CONTEXT, resolve that before continuing.
  3. If implementer returns DONE_WITH_CONCERNS, read the concerns before review and decide whether to fix, narrow scope, or continue.
  4. Dispatch spec-reviewer with the original task, relevant spec excerpts, changed files, and implementer report.
  5. Fix or escalate every spec-review issue before requesting code-quality review.
  6. Dispatch code-quality-reviewer only after spec review reports compliance; keep its existing maintainability objective unchanged.
  7. Fix Critical and Important code-quality issues before handoff, or document why a finding is intentionally deferred.
  8. This surface alone owns the change-risk/v2 state machine. Invoke change-risk-reviewer only after code-quality review, keep its closed ChangeRiskOrchestrationStateV1 handoff snapshot-bound, and never let a nested surface invoke it again for an unchanged snapshot.
  9. Initial review is clean-room; remediation supplies prior fingerprints and searches the complete updated snapshot; required final confirmation is clean-room again. Any code change invalidates the preceding clean result. Files under docs/review-learning/ are excluded from snapshot identity and do not invalidate a terminal result. An initial or remediation review is never repeated against an unchanged snapshot; a required final confirmation is the exception.
  10. Apply these bounded owner rules and preserve counters, actual snapshot IDs, and completed-round fingerprint and remediated-cluster-key history across resume:

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.
