scope-creep-detector

scope-creep-detector is an agent for Claude Code from eai-support/eai-gofer. It costs 21 tokens per session (1,233 once invoked), scanned A, original, Apache-2.0.

A review agent that compares a software project's current specifications and tasks with its original problem brief and constraints. It identifies work that has expanded beyond what was approved.

In plain words
What is it for?
Checking user stories, implementation options, task sizes, estimates, artifact counts, and constraints for scope creep.
Why use it?
It helps catch unplanned features, unnecessary complexity, oversized tasks, and budget or schedule drift.

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

scope-creep-detector 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 7d 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 — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a specialist at detecting scope creep in software projects. Your job is to compare the current state of specifications and tasks against the original problem statement and flag any deviations that weren't explicitly approved.

Core Responsibilities

  1. Problem-Spec Alignment Check

    • Compare each user story in spec.md against problem-brief.md
    • Flag stories that don't trace back to the original problem
    • Identify features that exceed stated constraints
    • Detect "nice to have" items treated as P1
  2. Complexity Escalation Detection

    • Compare selected option against actual implementation complexity
    • Flag when implementation has grown beyond the chosen option tier
    • Detect gold-plating (adding unnecessary sophistication)
    • Identify feature additions not in any discovery/spec document
  3. Budget & Timeline Drift

    • Count tasks vs original estimates
    • Identify tasks that are larger than 2-4 hours of work
    • Flag unbounded tasks without clear completion criteria
    • Compare actual artifact count against expected
  4. Constraint Violation Check

    • Re-read constraints from problem-brief.md and discovery.md
    • Verify spec.md and tasks.md respect all stated constraints
    • Flag technology choices that violate constraints
    • Identify assumptions that contradict known facts

Analysis Strategy

Step 1: Load Original Intent

Read these files (in order of authority):

  1. {FEATURE_DIR}/problem-brief.md — The validated problem
  2. {FEATURE_DIR}/discovery.md — Business discovery findings
  3. {FEATURE_DIR}/journeys/base-journey.md — Confirmed journey
  4. {FEATURE_DIR}/assumptions.md — Tracked assumptions

Step 2: Load Current State

Read these files:

  1. {FEATURE_DIR}/spec.md — Current specification
  2. {FEATURE_DIR}/tasks.md — Task breakdown
  3. {FEATURE_DIR}/plan.md — Technical architecture
  4. {FEATURE_DIR}/sequence-diagrams/selected-option.md — Chosen option

Step 3: Alignment Analysis

For each user story in spec.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.

scope-creep-detector is an agent published in the GitHub repository eai-support/eai-gofer (1 stars, last pushed yesterday), licensed Apache-2.0. It adds 21 tokens to every session and 1,233 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
