change-init

change-init is a skill for Claude Code from tikalk/adlc-team-skills. It costs 72 tokens per session (3,600 once invoked), scanned A, original, MIT.

A git-history analysis tool that finds linked commits, groups them into change stories, and records the decisions behind past code changes as draft Change Decision Records.

In plain words
What is it for?
Use it when learning an existing repository, preparing a refactor, or building project memory from issue-linked git history.
Why use it?
It recovers project history that may exist only in commit messages, issue trackers, and code changes, including follow-up fixes and reversions.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

change-init 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.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/bash/setup-change-init.sh, scripts/powershell/setup-change-init.ps1), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What this skill does

Mine git history for Change Decision Records (ChDRs) — the why behind how the code came to be — and write them as draft records for human review.

A ChDR captures a decision that was made in the past and survives only in commits + linked issue trackers:

  • Scan a window of git log for commit messages that reference an issue tracker (JIRA keys, GitHub/GitLab #NNN, MR !NNN, or issue URLs)
  • Cluster commits sharing one issue key into a single change story
  • Best-effort fetch the issue title/body (GitLab via MCP, GitHub via gh, else link-only) for requirement-level context
  • Infer the Decision from the diff summary; record Consequences (reverts, follow-up fix chains — the negative knowledge almost never documented elsewhere)
  • Write ChDR-{NNN}.md to {REPO_ROOT}/.adlc/drafts/chdr/ with status Discovered
  • Regenerate {REPO_ROOT}/.adlc/drafts/chdr/chdr.md index

Key differences from the levelup family:

Skill Source Record Question answered
/levelup-init current code (what IS) CDR (Context Directive) what patterns are reusable
/levelup-specify current session CDR what was learned this session
/change-init (this skill) git history (why it BECAME) ChDR (Change Decision) why this code exists / what was tried and reverted

ChDRs are project-local memory (this repo's evolution), not team-wide context — they fail the levelup "team-wide applicability" signal gate. They publish to {REPO_ROOT}/.adlc/memory/chdr/ (see /change-publish), and their index is injected at session start by team-boot.

When to use

  • Brownfield onboarding: give an agent project memory without anyone writing docs
  • Before refactoring unfamiliar code: surface Chesterton's fences — constraints that exist only in old commits + tickets
  • Recovering lost rationale: when ADRs were never written but commits + issues exist
  • Post-incident learning: revert/fix chains are first-class output

Changes

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.
