Problem Statement

Current Behavior

The Agent Development Organization Guide can be modified over time, but there is currently no formal mechanism for tracking governance changes.

As a result, it is difficult to determine:

• What changed
• When the change occurred
• Why the change was made
• Which issue requested the change
• Which version introduced the change

Over time, undocumented modifications may create confusion, inconsistent interpretations, and governance drift.

---

Expected Behavior

All governance document changes should be traceable.

Anyone reviewing the system should be able to answer:

• What changed?
• Why was it changed?
• When was it changed?
• Which issue triggered the change?

Governance documents should maintain a complete history of modifications.

---

Impact

As the organization grows from approximately 12 members toward 20–80 members, undocumented governance changes may result in:

• Inconsistent agent behavior
• Conflicting workflow interpretations
• Difficulty auditing decisions
• Loss of organizational knowledge
• Reduced trust in governance documents

---

Acceptance Criteria

CHANGELOG.md

A dedicated CHANGELOG.md file exists.

The changelog must:

• Record every modification to governance documents
• Maintain historical entries permanently
• Never overwrite previous records

Each entry must include:

• Date
• Version Number
• Issue ID
• Summary of Changes
• Reason for Change

---

Governance Update Process

Any change to:

• Agent Development Organization Guide
• Governance policies
• Workflow rules
• Agent responsibilities
• Verification requirements

must include:

1. Governance Issue
2. Guide Update
3. Changelog Update
4. Version Increment

---

Release Requirements

Governance-related releases may not be approved unless:

• Guide changes are documented
• CHANGELOG is updated
• Version number is updated

---

Proposed Files

Agent_Development_Organization_Guide.md

Defines current governance rules.

---

CHANGELOG.md

Records all governance changes.

---

VERSION.md

Stores current governance version.

Example:

v1.3.0

---

Proposed CHANGELOG Format

Version 1.0.0

Date: 2026-06-17

Issue ID: Initial Release

Added

• Human User role
• Product Manager Agent
• Workflow Agent
• Architecture Agent
• Implementation Agent
• QA Agent
• Audit Agent
• Release Agent

Notes

Initial governance framework established.

---

Version 1.1.0

Date: YYYY-MM-DD

Issue ID: GOV-001

Added

• Acceptance Criteria section

Reason

QA and Release decisions required a formal definition of completion.

---

Version 1.2.0

Date: YYYY-MM-DD

Issue ID: GOV-002

Added

• Issue Decomposition process

Reason

Large GitHub issues were causing unnecessary feature redesigns.

---

Version 1.3.0

Date: YYYY-MM-DD

Issue ID: GOV-003

Added

• Verification and Rework Loop

Reason

Changes could previously bypass re-verification after modification.

---

Success Criteria

After implementation:

• Every governance change is traceable
• Governance evolution is auditable
• Historical decisions can be reconstructed
• Organizational knowledge is preserved
• Future contributors can understand why rules exist

---

Rationale

The governance framework itself should be governed.

Without version history and change tracking, the organization risks creating undocumented rules whose origins, purpose, and approval history cannot be determined.

Governance documents should be treated as first-class system artifacts and maintained with the same discipline as production code.

Delivered — governance changes are now traceable:

• CHANGELOG.md — governance-scoped, append-only, never overwritten; every entry carries Date · Version · Issue ID · Summary · Reason. Backfilled with v1.0.0, covering the two documents this issue's siblings produced (architecture Define System Roles, Permissions, Ownership Model, and Approval Workflow #49, audit framework Establish Issue Decomposition Audit Framework #50) and bringing the existing governance docs (Definition of Done / verification requirements, permissions reference, workflow-testing rules) formally under the changelog's scope.
• VERSION.md — current governance version (v1.0.0) with semver increment rules (major = model change · minor = new rules · patch = clarification).
• The update process is now a standing rule (stated at the top of the changelog): any governance change requires ① a governance issue → ② the document update → ③ a changelog entry → ④ a version increment — and governance-touching releases may not ship unless all four are present.

One naming note: this issue references an "Agent Development Organization Guide" as the primary governed document. That guide lives as the set of docs listed in the changelog header rather than a single file (#38). If you'd prefer them consolidated into one Agent_Development_Organization_Guide.md, that's a v1.1.0 change — say the word and it goes through this very process as its first real entry.
