Format

The ChangeLog file is a Markdown formatted file named CHANGELOG.md, and contains sections with headers in the style N.M.K (YYYY-MM-DD).

Each ChangeLog entry is always formatted as...

`<change-type/> [<artifact-kind/>]: <summary/>`

...where the <change-type/> is one of the following tags and their usual related changes:

-   `FEATURE`:     new        functionality or configuration
-   `IMPROVEMENT`: improved   functionality or configuration
-   `BUGFIX`:      corrected  functionality or configuration
-   `UPDATE`:      updated    functionality or configuration
-   `CLEANUP`:     cleaned up functionality or configuration
-   `REFACTOR`:    refactored functionality or configuration

The <artifact-kind/> is one or more of the following artifact tags, classifying which kind of artifact the change primarily touches. If multiple artifact kinds apply, comma-separate them (e.g. [arch, code]):

-   `spec`:  requirement/specification artifacts
-   `arch`:  architecture/design artifacts
-   `code`:  source code artifacts
-   `docs`:  documentation artifacts
-   `infr`:  infrastructure/build/tooling artifacts
-   `othr`:  any other artifacts

The <summary/> is not longer than about 60-80 characters. The ChangeLog entries for a single product release version are also always grouped and sorted according to the above <change-type/> list.

Processing

<flow>

1. <step id="STEP 1: Locate and read ChangeLog entries">

   The ChangeLog file CHANGELOG.md is located in the current directory or one of the parent directories of the current project. Locate and read this file. Store its relative path in <filename/>.

   You MUST NOT output anything, except the result with the following <template/>:

   <template> <ase-tpl-bullet-normal/> **CHANGELOG FILE:** `<filename/>` </template> </step>
2. <step id="STEP 2: Determine artifact changes">

   You MUST NOT output anything, except introduce the current operation with an output based on the following <template/>:

   <template> <ase-tpl-bullet-normal/> **DETERMINE ARTIFACT CHANGES:** </template>

   To update the entries of the most recent ChangeLog section, consult the Git commits plus the currently already staged changes in the Git index, but ignore the Git stash and still unstaged changes.

   For finding the corresponding Git commits, first determine the correct baseline Git tag. Take the N.M.K from the first (most recent) level-2 header in the ChangeLog file and check whether a corresponding Git tag already exists with the command git tag --list N.M.K. If this command produces no output, the first section is still in-progress/untagged, so use the N.M.K from the second level-2 header as the baseline tag instead. If no second level-2 header exists (very first, still untagged release), skip the baseline tag and check all Git commits with the command git log HEAD --numstat --pretty=format:'%h: %s' instead. If this command does produce output, the first section is already released/tagged, so use the N.M.K from the first level-2 header as the baseline tag. Then check all Git commits between HEAD and this baseline tag with the command git log N.M.K..HEAD --numstat --pretty=format:'%h: %s'.

   For finding the corresponding staged Git changes in the Git index, use the command git diff --cached --numstat, but silently skip already existing changes to the CHANGELOG.md file itself. If still no corresponding ChangeLog entry exists for these staged Git changes, derive a meaningful one from a git diff --cached command.

   </step>
3. <step id="STEP 3: Complete ChangeLog entries">

   You MUST NOT output anything, except introduce the current operation with an output based on the following <template/>:

   <template> <ase-tpl-bullet-normal/> **COMPLETE ENTRIES:** </template>

   Without immediately modifying the CHANGELOG.md file, complete the entries in the first (most recent) section only, by adding the corresponding (most recent) Git commits and staged changes only.

   For each Git commit, reduce the Git commit messages to a single short <summary/> sentence, not longer than 60-80 characters.

   For each entry, also determine the <artifact-kind/> artifact kind tag(s) from the paths of the changed files. To classify a changed file to its artifact class, call the ase_artifact_list(kind: [ ... ]) tool of the ase MCP server once, passing the kind tokens (spec, arch, code, docs, infr, othr), and read the returned artifacts array of { kind, files } objects to match each changed file to its kind. Use the matched lower-cased kind directly as its <artifact-kind/> tag, and comma-separate multiple tags when more than one artifact class applies.

   If a <summary/> is too short or especially is not comprehensible enough because of too little context information, add some essential context, especially references to the class/module/package, etc. For this, if necessary, read the related source files with a corresponding git show command to get a better understanding of this context.

   </step>
4. <step id="STEP 4: Consolidate and sort ChangeLog entries">

   You MUST NOT output anything, except introduce the current operation with an output based on the following <template/>:

   <template> <ase-tpl-bullet-normal/> **CONSOLIDATE ENTRIES:** </template>

   Without immediately modifying the CHANGELOG.md file, consolidate the entries in the first (most recent) section only, by summarizing and merging closely related entries. Perform the entry consolidation per <change-type/> group only.

   Without immediately modifying the CHANGELOG.md file, sort the entries in the first (most recent) section only. Instead of the chronological commit order, group the entries by the <change-type/>s.

   </step>
5. <step id="STEP 5: Write modified ChangeLog entries">

   You MUST NOT output anything, except introduce the current operation with an output based on the following <template/>:

   <template> <ase-tpl-bullet-signal/> **UPDATING CHANGELOG:** </template>

   Finally, update the CHANGELOG.md file with the completed, consolidated and sorted ChangeLog entries. Also, update the date YYYY-MM-DD in the N.M.K (YYYY-MM-DD) header of the first (most recent) section.

   You MUST NOT output any further summary or give any further explanations.

   </step>
