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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00064 | $0.00799 |
| Opus 5 | $0.00032 | $0.00400 |
| Sonnet 5 | $0.00013 | $0.00160 |
| Haiku 4.5 | $0.00006 | $0.00080 |
Grade A, and why
effort-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 10d 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 — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Effort Impact Matrix
Use this skill to run Effort Impact Matrix as a practical consulting method, not as a generic framework explanation.
Method Notes
- Normalize items so each one is an executable action.
- Use quick wins, major bets, fill-ins, and deprioritize/defer.
Required Inputs
Collect or infer these inputs before execution:
- candidate actions
- impact estimate
- effort estimate
- time or resource constraints
If an input is missing, do not block automatically. Mark it as missing, state the assumption used, and add a validation action.
When Not To Use
Do not use when impact and effort cannot be estimated on a comparable basis or when hard dependencies determine the sequence. This is a relative triage tool, not a full investment case.
Adjacent Methods
rice-scoring: prioritize a backlog using Reach, Impact, Confidence, and Effort.wsjf-prioritization: sequence work using Cost of Delay divided by Job Size.decision-matrix: make a one-time option choice using explicit weighted criteria.
Step-by-Step Execution
| Step | Required input | How to execute | Output |
|---|---|---|---|
| List actions | Candidate actions or initiatives. | Rewrite broad ideas into one-action items. | Normalized action list. |
| Define scoring anchors | Objective, constraints, available capacity. | Define what high/medium/low impact and effort mean. | Scoring scale. |
| Score each action | Action list, evidence, effort estimates. | Rate impact and effort separately; mark confidence. | Scored action table. |
| Place quadrants | Scored table. | Classify quick wins, major bets, fill-ins, and defer/drop items. | Effort-impact matrix. |
| Choose sequence | Matrix, dependencies, timing, risk. | Recommend first actions, later actions, and items to reject or validate. | Sequenced action plan. |

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.

effort-impact-matrix is a skill published in the GitHub repository fzfclee/consulting-skills (4 stars, last pushed 22d ago), licensed Apache-2.0. It adds 64 tokens to every session and 799 once invoked, about $0.0003 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.
