"Generate a changelog entry"	Changelog from git history

Prerequisites

None — all tools and references are workspace-local.

Scope

In Scope

All markdown documentation except agent-output/**/*.md:

• docs/ — user-facing docs (quickstart, workflow, troubleshooting, etc.)
• docs/prompt-guide/ — agent & skill prompt examples
• docs/exec-plans/tech-debt-tracker.md — tech debt inventory
• README.md — repo root README
• CONTRIBUTING.md — contribution guidelines
• CHANGELOG.md — release history
• QUALITY_SCORE.md — project health grades
• .github/instructions/docs.instructions.md — architecture tables

Out of Scope (Has Own Validators)

Path	Governed By
agent-output/**/*.md	azure-artifacts.instructions.md + validators
.github/agents/*.agent.md	agent-definitions.instructions.md
.github/skills/azure-artifacts/templates/	Read-only reference (do not modify)
**/*.bicep	bicep-code-best-practices.instructions.md

Step-by-Step Workflows

Workflow 1: Update Existing Documentation

1. Identify target files: Determine which files in docs/ need updates.
2. Read latest version: Always read the current file before editing.
3. Load standards: Read references/doc-standards.md for conventions.
4. Apply changes: Follow the doc-standards conventions strictly:
   • 120-char line limit (CI enforced)
   • Single H1 rule (title only)
   • File header: # {Title} + > Version {X.Y.Z} | {description}
   • Version number from VERSION.md (single source of truth)
5. Verify links: Check all relative links resolve to existing files.
6. Run validation: Offer to run npm run lint:md and npm run lint:links.

Workflow 2: Add Documentation for New Entity

When a new agent or skill is added to the repo:

1. Read architecture: Load references/repo-architecture.md for current entity inventory and naming conventions.
2. Identify all files needing updates:
   • New agent → update docs/README.md agent tables, .github/instructions/docs.instructions.md agent count/table
   • New skill → update docs/README.md skill tables, .github/instructions/docs.instructions.md skill count/table
3. Match existing patterns: Study adjacent entries in each table to match column format, emoji conventions, and description style.
4. Update counts: Increment totals in section headings (e.g., "## Skills (10)" → "## Skills (11)").
5. Cross-reference check: Search for other files mentioning the old count and update them too.

Workflow 3: Freshness Audit (Staleness Check)

1. Load checklist: Read references/freshness-checklist.md.
2. Scan each audit target:
   • Version numbers match VERSION.md
   • Agent/skill counts match filesystem
   • Tables list all entities present in filesystem
   • No references to removed/renamed agents
3. Check project health files:
   • Read QUALITY_SCORE.md — verify grades still reflect reality
   • Read docs/exec-plans/tech-debt-tracker.md — verify items still relevant
4. Report findings: Present a table of issues found with:
   • File path, line number, issue description, suggested fix
5. Auto-fix: For each issue, propose the exact edit and apply it after user confirmation (or immediately if user said "fix all").
6. Update health metrics: If fixes change quality grades, update QUALITY_SCORE.md.

Workflow 4: Explain the Repo Architecture

1. Load architecture: Read references/repo-architecture.md.
2. Answer questions: Use the reference to explain how components connect — agents, skills, instructions, templates, artifacts, and the 7-step workflow.
3. Cite sources: Point to specific files when answering.
4. Stay current: If the reference seems outdated vs. filesystem, note the discrepancy and offer to update the reference.

Workflow 5: Generate Changelog Entry

1. Find last version tag: Run git tag --sort=-v:refname | head -1.

2. Get commits since tag: Run git log --oneline {tag}..HEAD --no-merges.

3. Classify by type: Map conventional commit prefixes to Keep a Changelog sections:

   • feat: → ### Added
   • fix: → ### Fixed
   • docs:, style:, refactor:, perf:, test:, build:, ci:, chore: → ### Changed
   • feat!: or BREAKING CHANGE: → ### ⚠️ Breaking Changes

4. Format entry: Match the style in CHANGELOG.md:

   ## [{next-version}] - {YYYY-MM-DD}
   
   ### Added
   
   - Description of feature ([commit-hash])
   
   ### Changed
   
   - Description of change ([commit-hash])
   
   ### Fixed
   
   - Description of fix ([commit-hash])
   

5. Determine version bump:

   • Breaking change → major
   • feat: → minor
   • fix: only → patch

6. Present to user: Show the formatted entry for review before inserting into CHANGELOG.md.

Workflow 6: Proofread Documentation

A three-layer review: language quality, tone/terminology, and technical accuracy.

1. Select scope: Ask user which files to review, or default to all files in docs/.

2. Layer 1 — Language quality:

   • Run npm run lint:prose (Vale) for automated prose checks.
   • Manually scan for: grammar errors, spelling mistakes, passive voice, awkward phrasing, overly long sentences (>30 words).

3. Layer 2 — Tone and terminology:

   • Verify consistent terminology against docs/GLOSSARY.md.
   • Check tone is active and action-oriented (not academic/passive).
   • Flag jargon not defined in the glossary.
   • Ensure agent/skill names use exact casing from their frontmatter (name: field) — e.g., "Bicep Code" not "bicep code agent".

4. Layer 3 — Technical accuracy:

   • Load references/repo-architecture.md for ground truth.
   • Verify agent/skill counts, names, and descriptions match the actual filesystem.
   • Confirm workflow step numbers and artifact filenames are correct.
   • Check that capability claims are truthful (e.g., if a doc says "supports 8 skills", verify 8 skill folders exist).
   • Cross-check version numbers against VERSION.md.

5. Report findings: Present a table per file:

   | #   | Line | Layer       | Issue                      | Suggestion       |
   | --- | ---- | ----------- | -------------------------- | ---------------- |
   | 1   | 12   | Language    | Passive voice              | Rewrite actively |
   | 2   | 34   | Terminology | "IaC tool" not in glossary | Use "Bicep"      |
   | 3   | 56   | Accuracy    | Says 6 agents, actual is 8 | Update count     |
   

6. Apply fixes: After user review, apply corrections. For language/tone fixes, show before/after for each change. For accuracy fixes, apply directly (same as freshness audit).

Workflow 7: Process Freshness Issues

Trigger: "Fix the docs freshness issue" or auto-created GitHub issue with docs-freshness label

1. Read the issue body for the findings table
2. For each finding, apply the appropriate fix from the freshness checklist
3. Run npm run lint:docs-freshness to verify 0 findings remain
4. Summarize changes made

Guardrails

• Never modify files in agent-output/, .github/agents/, or .github/skills/azure-artifacts/templates/
• Always read the latest file version before editing
• Always verify line length ≤ 120 characters after edits
• Preserve existing Mermaid diagram theme directives
• Use VERSION.md as the single source of truth for version numbers

Troubleshooting

Issue	Solution
Lint fails on line length	Break lines at 120 chars after punctuation
Link validation fails	Check relative paths resolve; use standard markdown link format
Version mismatch	Read VERSION.md and propagate to all docs
Count mismatch	List .github/agents/ and .github/skills/ directories
