impact-matrix

impact-matrix is a skill for Claude Code, Codex from sembraniteam/claude-plugins. It costs 134 tokens per session (1,146 once invoked), scanned A, original, MIT.

A method for ranking issues by their user or business impact and the effort needed to fix them. It uses a 1–3 score for each dimension and calculates priority as impact divided by complexity.

In plain words
What is it for?
Use it to triage findings, compare performance fixes, build a priority matrix, rank work for a sprint, or choose the highest-impact change.
Why use it?
It helps teams decide what to fix first when there are more issues than time. The matrix makes quick wins, strategic projects, low-priority work, and work to defer easier to distinguish.

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

impact-matrix 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.

Impact Matrix

Complexity × Impact Prioritization Matrix

Scoring Dimensions

Score each finding on two dimensions (1–3 scale):

Impact — user or business effect if fixed

Score Meaning
3 Directly visible to users or causes SLO breach
2 Measurable improvement but not directly user-facing
1 Minor improvement; internal or technical benefit only

Complexity — effort required to implement the fix

Score Meaning
1 <1 day: config change, add index, fix cache header
2 1–5 days: refactor one component, add cache layer, pool objects
3 >1 sprint: architectural change, data model migration, platform upgrade

Priority score = Impact ÷ Complexity (higher = act sooner)

  • Quick Wins → Ship immediately; highest ROI
  • Strategic Projects → Schedule in roadmap; break into milestones
  • Low-Hanging Fruit → Batch in a cleanup sprint
  • Avoid / Defer → Do not prioritize; revisit if scale or impact changes

Scoring Template

When given a list of findings, produce this prioritized table:

| # | Finding                        | Impact | Complexity | Score | Quadrant          |
|---|--------------------------------|--------|------------|-------|-------------------|
| 1 | Add index on orders.user_id    |   3    |     1      |  3.0  | Quick Win         |
| 2 | Migrate to async I/O           |   3    |     3      |  1.0  | Strategic Project |
| 3 | Enable gzip on API responses   |   2    |     1      |  2.0  | Low-Hanging Fruit |
| 4 | Rewrite ORM to raw SQL         |   1    |     3      |  0.3  | Avoid / Defer     |

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.
