changes

changes is a skill for Claude Code, Codex from Amatofrancesco99/thoughtweave. It costs 51 tokens per session (2,207 once invoked), scanned A, original, MIT.

A communication skill that explains coding changes after a feature has been implemented. It describes what changed, why it changed, accepted trade-offs, and security problems that were found and fixed.

In plain words
What is it for?
Use it after implementing a feature from a specification to prepare a clear change summary. It requires a spec.md file as the reference point.
Why use it?
It gives developers, reviewers, managers, and other stakeholders a shared explanation of the work instead of leaving them to infer it from code changes.

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

changes 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.

How it starts

The opening of the file, as written. The whole thing — 199 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/changes

Generate a human-readable explanation of implemented changes. The purpose is communication, not documentation. The audience includes developers, reviewers, managers, and stakeholders.

The skill is a tool for the developer, not a replacement. The developer stays at the centre - every decision about what to document, which trade-offs to highlight, and which risks to accept is driven by the developer's judgement. The skill surfaces information, but the developer decides what matters.

Pre-condition Check

Before any questions, verify that a specification exists for this feature:

  1. Determine the target folder (ask if not known or inheritable from context).
  2. Check if spec.md exists in that folder.
  3. If spec.md does not exist, refuse to proceed: "A changes document documents what changed relative to a specification. Without a spec, there is no anchor to compare against. Please run /sdd first to create a specification for this feature."
  4. If spec.md exists but is incomplete, warn and ask whether to proceed or complete the spec first.
  5. If spec.md is complete but lacks documented hidden assumptions, flag this and ask the user to review.

[!IMPORTANT] This check is non-negotiable. The changes skill cannot produce meaningful output without a spec.

Implementation Validation

Before generating the changes document:

  1. Read the spec.md to extract requirements, acceptance criteria, decisions, and constraints.
  2. Inspect the actual implementation (code changes, file modifications, architecture) and verify each maps back to a corresponding item in the spec.
  3. If requirements from the spec are not addressed, flag them as unimplemented and ask if intentionally dropped.
  4. If the implementation includes behaviour not covered by the spec, flag it as untracked and ask for justification.
  5. If AGENTS.md exists, validate that the implementation respects its constraints, best practices, and architectural directives. Flag deviations.

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.

changes is a skill published in the GitHub repository Amatofrancesco99/thoughtweave (5 stars, last pushed 1mo ago), licensed MIT. It adds 51 tokens to every session and 2,207 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.
