tachi: Skill for Claude Code

.claude/skills/~aod-score/SKILL.md

~aod-score is a skill for Claude Code from davidmatousek/tachi. It costs 44 tokens per session (1,971 once invoked), scanned A, original, Apache-2.0.

A tool for recalculating an existing idea's ICE score when its expected impact, confidence, or effort changes. ICE is a prioritisation method based on those three factors.

In plain words
What is it for?
It is for finding an idea in GitHub Issues, reassessing its priority, and updating its score and related evidence.
Why use it?
It keeps the project's idea priorities aligned with new information instead of relying on an old score.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: names the AskUserQuestion tool.

This is davidmatousek/tachi's own configuration. It tells Claude Code how to work on tachi itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything tachi configures →

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

~aod-score 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 3d 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.

AOD Re-Score Skill

Purpose

Update an existing idea's ICE (Impact, Confidence, Effort) score when circumstances change, new information emerges, or priorities shift. Reads from and writes to the idea's GitHub Issue.

Source of Truth

GitHub Issues are the sole source of truth for backlog items. All idea state (ICE scores, status, evidence) is stored in the GitHub Issue body. BACKLOG.md is an auto-generated view regenerated from Issues.

Inputs

  • NNN, #NNN, or IDEA-NNN (legacy): The identifier of the idea to re-score (from user arguments)

Workflow

Step 1: Parse Input

Extract the idea identifier from user arguments. Accept three formats:

  • NNN (bare number, e.g., 21): Direct GitHub Issue lookup
  • #NNN (hash-prefixed, e.g., #21): Strip # prefix, direct lookup
  • IDEA-NNN (legacy, e.g., IDEA-009): Search issue titles for [IDEA-NNN] bracket tag

If invalid or missing, display usage: Usage: /aod.score NNN (or #NNN or IDEA-NNN)

Step 2: Find GitHub Issue

Search for the matching GitHub Issue:

For numeric input (NNN or #NNN):

source .aod/scripts/bash/github-lifecycle.sh && aod_gh_find_issue NNN

For legacy IDEA-NNN input:

source .aod/scripts/bash/github-lifecycle.sh && aod_gh_find_issue "[IDEA-NNN]"

If no issue is found, display an error and exit:

Error: No GitHub Issue found for {identifier}

Step 3: Read Current Scores

Read the GitHub Issue body using gh issue view {number} --json body,title. Parse the structured body to extract:

  • Description (from ## Idea section or title)
  • ICE scores (from ## ICE Score section)
  • Source (from ## Metadata section)
  • Status (from ## Metadata section)
  • Evidence (from ## Evidence section)

Step 4: Display Current Scores

Show the existing idea details:

CURRENT SCORES — #{issue_number}

GitHub Issue: #{issue_number}
Idea: {description}
Source: {source}
Date: {date}
Status: {status}

ICE Score: {total} (I:{impact} C:{confidence} E:{effort})
Priority Tier: {tier}

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.
