Codexicon v2.8.1

2.8.1 — Efficient diagnostics and verification output

• Classified exact read-only Codexicon manager plans and diagnostics without allowing apply mutations or abbreviated apply flags through the verification gate.
• Reduced successful canonical test output while preserving complete failure diagnostics.
• Returned subagent concurrency to user and runtime policy and added validation against reintroducing a project-level fixed cap.
• Made Git-heavy test-fixture cleanup clear read-only artifacts, retry, and fail visibly instead of silently accumulating workspace state on Windows.

Codexicon v2.8.0

2.8.0 — Bounded agent loops and trusted external research

• Added a selective engineering-loop skill for independent exploration, isolated implementation, integration, review, and evidence-based refinement.
• Added a read-only GitHub researcher profile and upstream-content trust contract.
• Added explicit $find-skills discovery with project-local, immutable provenance requirements and a dependency-free lock validator.
• Strengthened provenance verification to bind each lock entry to a local skill directory and verify its complete content digest; broadened shell write detection for sed and find inspection commands.
• Refreshed newcomer routing maps and the interactive playbook for bounded engineering loops, external skill discovery, and read-only GitHub research, and aligned CI action pins with their scanner versions.
• Added a paired direct-versus-delegated benchmark protocol without claiming unavailable live-agent metrics.
• Confined hook state and receipt paths to repository-local hashed namespaces, rejected symbolic-link escapes, strengthened immutable action-pin validation, and aligned the TruffleHog action wrapper with scanner v3.97.0.

Codexicon v2.5.0

Codexicon v2.5.0 is the first public release of the production-minded Codex project template.

Included

• Progressive project workflow from discovery through release
• Focused engineering, design, marketing, review, security, and shipping skills
• Compact repository guidance designed to reduce unnecessary context use
• Cross-platform setup, lint, test, security, and deploy wrappers
• Credential path protection, high-confidence secret scanning, and verification hooks
• Windows and Linux CI across Python 3.10 and 3.13
• Public onboarding, contribution, conduct, support, security, issue, and maintainer guidance
• A detailed visual playbook with a complete sports-app example

Codexicon is a governed starting point. Projects created from it must still replace placeholders, select their actual stack, implement appropriate application tests and operational controls, and pass their own production-readiness review.
