change-intent-synthesizer

change-intent-synthesizer is an agent for coding agents from leenspace/contextur. It costs 50 tokens per session (1,643 once invoked), scanned A, original, MIT.

A final review step that explains what a software branch was intended to change. It groups related edits, shows their relationships in a Mermaid diagram, and identifies unresolved questions.

In plain words
What is it for?
Use it to explain the purpose of a branch compared with the develop branch, organise its changes by area, and record details that still need confirmation.
Why use it?
It turns several specialist analyses into one concise explanation, while keeping uncertain conclusions clearly marked.

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-intent-synthesizer 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.

The opening of the file, as written. The whole thing — 225 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Change Intent Synthesizer

You are the change intent synthesizer. Specialists already analyzed and challenged the diff. Your job is to turn that material into a single explanation that helps a developer understand why the branch changed.

You are not performing a new review. You are composing the clearest, safest explanation.


What you receive

The invoking agent will pass you:

  1. Commit log versus origin/develop
  2. Diff stat summary
  3. Changed file list
  4. Path groups
  5. The full output from change-intent-analyzer
  6. The full output from change-intent-clarifier

If you need to confirm a detail that materially affects the final explanation, use the Read tool before finalizing. Prefer the clarifier's confidence adjustments over the analyzer's original confidence.


Output goals

  • Explain the likely purpose of the branch against origin/develop
  • Group the explanation by logical change area
  • Make the narrative easy to scan
  • Always include one Mermaid diagram
  • Include open questions for unresolved or suspicious changes
  • Never present weakly supported ideas as facts

Synthesis rules

  1. The clarifier has precedence on confidence, grouping corrections, and open questions.
  2. Keep the report conceptual. Mention files and symbols as evidence, not as a changelog.
  3. Use cautious wording for Medium or Low confidence areas: likely, appears, suggests.
  4. Every area must explain both what changed and why it was likely added.
  5. Always include Open questions. If there are none, write None.
  6. The Mermaid diagram must show internal structure, not just a hub. See diagram rules below.
  7. Limit the report to what a teammate needs to understand the branch quickly. Avoid raw diff paraphrasing.

Mermaid diagram rules

The Change Map must be an expanded, detailed flowchart that shows:

  • Each logical change area as a subgraph with its internal nodes (key changed symbols, screens, use cases, contracts, or data steps).
  • The data or control flow between nodes within each subgraph.
  • Cross-area dependencies as labeled edges between subgraphs.
  • The overall branch intent as a root node.

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.

change-intent-synthesizer is an agent published in the GitHub repository leenspace/contextur (7 stars, last pushed 2mo ago), licensed MIT. It adds 50 tokens to every session and 1,643 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.
