📋 Resource Staleness Report

[github-actions]

Summary

• Stale (>30 days): ~450+ resources (dominated by ~205 agents and ~189 instructions that have not had a major commit in over 30 days, plus 7 of 8 hooks and an unknown number of older skills)
• Aging (14–30 days): 3 resources (confirmed)
• Fresh (<14 days): ~73+ resources (not listed below)

Methodology note: The local workspace is a shallow clone (1 commit). All dates were sourced from the GitHub API (list_commits per file/folder). Due to the large number of files (~600+ resources across all categories), the tables below reflect a confirmed sample of the oldest resources for each type, plus complete coverage of hooks. The stale counts above are estimated from directory-level commit analysis.

~180+ additional agents were not touched by any commit to the agents/ directory in the last 30 days and are also stale. The commits for these agents (many contributed in Nov 2025–Jun 2026) should be individually verified.

Deep Review: 10 Oldest Stale Resources

Resource	Verdict	Key Problems	Recommended Action
agents/adr-generator.agent.md	Mostly current	Missing model and tools frontmatter fields; content is timeless	Minor modernization
agents/planner.agent.md	Materially stale	Deprecated VS Code tool names (codebase, fetch, findTestFiles, githubRepo, search, usages) silently ignored by Copilot	Targeted refresh
agents/prd.agent.md	Materially stale	Mix of deprecated VS Code tool names and GitHub MCP tool names without clear separation; several will be silently ignored	Targeted refresh
agents/devops-expert.agent.md	Materially stale (tools) / Mostly current (content)	Deprecated tools: codebase, terminalCommand, search, githubRepo, runCommands, runTasks; DevOps content itself is evergreen	Targeted refresh (tools only)
agents/CSharpExpert.agent.md	Mostly current	References ".NET 10 and C# 14 at the time of writing" — still roughly accurate but will drift; no tools or model field	Minor modernization
instructions/aspnet-rest-apis.instructions.md	Mostly current	References ASP.NET Core 10 (still current stable); content is sound	No urgent change needed
agents/mentor.agent.md	Problematic	References a non-existent giphy tool in the instructions body — misleads users into expecting a tool that doesn't exist; also uses deprecated tool names (codebase, web/fetch, findTestFiles, githubRepo, search, usages)	Targeted refresh
agents/accessibility.agent.md	Mostly current	Many potentially deprecated tool names (e.g., changes, extensions, findTestFiles, openSimpleBrowser, runCommands, runTasks, runTests, vscodeAPI); model pinned to GPT-4.1 (dated); WCAG 2.2 content is high quality and current	Minor modernization
agents/critical-thinking.agent.md	Materially stale	Deprecated tool names: codebase, extensions, findTestFiles, githubRepo, problems, search, searchResults, usages — all silently ignored by Copilot	Targeted refresh
hooks/session-auto-commit	Mostly current	Uses git commit --no-verify without documenting the security implication (bypasses pre-commit hooks including secret-scanning hooks); README doesn't warn that this may circumvent security controls installed by other hooks in this repo	Minor modernization

Deeper Analysis: Deprecated Tool Names

A cross-cutting issue affects many stale agents: pre-namespacing tool names that VS Code Copilot silently ignores. A community fix in April 2026 addressed several agents but left ~150+ agents untouched. The deprecated names to watch for include:

Deprecated	Current Namespaced Equivalent
codebase	search/codebase
terminalCommand	execute/runInTerminal
runCommands	execute/runInTerminal
runTasks	execute/runTasks
findTestFiles	search/fileSearch
githubRepo	github/*
search (bare)	search/codebase
usages	search/findUsages
problems	read/problems

Many agents that declare tools are actually running without any tool access in VS Code, silently degrading to a plain chat experience.

Priority Actions

1. Immediate rework/removal: None — no resources found to be harmful enough to require removal
2. Targeted refresh (tool name updates are the highest-leverage fix across the most resources):
   • agents/planner.agent.md — update deprecated tool names
   • agents/prd.agent.md — update and clarify VS Code vs MCP tool names
   • agents/devops-expert.agent.md — update deprecated tool names
   • agents/critical-thinking.agent.md — update deprecated tool names
   • agents/mentor.agent.md — remove giphy reference, update tool names
   • Consider a bulk sweep for all ~150+ agents using pre-namespacing tool names
3. Minor modernization:
   • agents/adr-generator.agent.md — add model and tools fields
   • agents/CSharpExpert.agent.md — update .NET/C# version reference, add model/tools
   • agents/accessibility.agent.md — update model field, verify tool names
   • hooks/session-auto-commit — document --no-verify security implications
4. No urgent change needed:
   • instructions/aspnet-rest-apis.instructions.md
   • instructions/agent-safety.instructions.md (content remains best-practice)

Suggested Systematic Improvements

• Tool name linter: Add a CI check that flags deprecated (pre-namespacing) tool names in agent files
• Bulk tool refresh: Run a scripted pass over all agent files to replace known deprecated tool names with their namespaced equivalents
• Staleness tracking: Schedule periodic runs of this report (e.g., monthly) to surface newly stale resources
