Agent Extension Visual

Analyze agent extensions and generate self-contained HTML wiki reports (or inline markdown) with security audit and plugin profiles. Currently supports Claude Code plugins.

Instructions

Input Parsing

Determine the analysis target from the user's message:

1. Path contains / → local path (resolve relative to cwd)
2. Contains github.com or https:// → GitHub URL
3. Other text → installed plugin name (search ~/.claude/plugins/cache/)
4. Nothing specified → current directory (scan .claude/, CLAUDE.md, plugins/)

For GitHub URLs, support subpath patterns:

• github.com/owner/repo → clone entire repo
• github.com/owner/repo/tree/branch/plugins/foo → clone repo, analyze subpath only

Language Detection

Determine the output language:

1. Explicit language argument: --lang <code> (e.g., --lang ko, --lang fr, --lang zh) → use that language. Any language code is valid
2. User message text: Detect the language of the message (excluding URL/path) and match it
   • Examples: Korean text → Korean, Japanese text → Japanese, "en español" → Spanish, "auf Deutsch" → German
3. URL only with no other text: Use AskUserQuestion to ask the user's preferred language

Pass the detected language to sub-agents and use it for Phase 5 report assembly.

Analysis Mode Detection

Determine what to analyze:

Mode	Trigger Keywords	Scope
analyze (default)	"analyze", "inspect", "report", "wiki", "document"	Full analysis and Plugin Profile
security	"security audit", "permission analysis"	Security only
overview	"overview", "summary"	Identity + inventory only

Output Format Detection

Determine how to present the result (independent of analysis mode):

Format	Trigger	Applies to
HTML (default)	Default for analyze mode	analyze only
Inline markdown	"--format md", "markdown", "md", "inline", "text"	analyze only
Inline markdown (always)	—	security, overview (too brief for HTML)

Intent Check

Why: An analysis for potential users focuses on capabilities and compatibility; an analysis for security reviewers focuses on permissions and risk. The audience shapes emphasis across all report sections.

If the user's message already conveys clear intent (e.g., "security audit", "is this plugin safe", or a specific analysis mode keyword), skip this step.

If the request is ambiguous (e.g., just a plugin path with no other context), use AskUserQuestion to ask up to 2 questions:

1. Audience: Who will read this? (yourself, your team, plugin marketplace reviewers)
2. Focus: Any specific concern? (security, architecture, compatibility, general overview)

Defaults:

• Audience: the user themselves (evaluating the plugin)
• Focus: balanced full analysis

Pass audience and focus context to the analysis and report generation phases.

Workflow

Phase 1: Source Acquisition

• Local path: Verify directory exists, proceed directly
• Installed plugin: Search ~/.claude/plugins/cache/ for matching directory
• GitHub URL: Clone to /tmp/agent-extension-visual-{dirname}:
  1. Generate {dirname} — pick any 8-character hex string yourself (e.g., a1b2c3d4)
  2. Clone directly (no mkdir needed — git creates the target directory):

     Bash(gh repo clone {owner/repo} /tmp/agent-extension-visual-{dirname})
     

     This is the only Bash command needed for cloning. Do not add extra commands for saving state or generating random strings. For subpath URLs (github.com/owner/repo/tree/branch/plugins/foo):
  3. Extract owner/repo for cloning
  4. Extract the subpath after /tree/{branch}/ (e.g., plugins/foo)
  5. Clone the full repo, then set the analysis target to the subpath within the clone
• Current directory: Use cwd

If source cannot be found, inform user and stop.

Source context — save for later phases (source links in report):

Source type	source_type	source_base	github_url
Local path	local	{absolute-path}	—
Installed plugin	local	{cache-path}	—
GitHub URL (root)	github	/tmp/agent-extension-visual-{dirname}	https://github.com/{owner}/{repo}/blob/{branch}
GitHub URL (subpath)	github	/tmp/agent-extension-visual-{dirname}/{subpath}	https://github.com/{owner}/{repo}/blob/{branch}/{subpath}

When cloning a subpath URL (e.g., github.com/owner/repo/tree/main/plugins/foo), include the subpath in both source_base and github_url so that relative paths from the plugin root produce correct source links.

Phase 2: Discovery

Why: Accurate component inventory prevents analysis agents from missing or hallucinating plugin components.

Scan the target directory for all plugin components.

Step 1: Run 3 Glob calls in parallel (single message):

#	Pattern	Captures
1	**/*.md	SKILL.md, agent .md, command .md, CLAUDE.md, README.md, CHANGELOG.md
2	**/*.json	plugin.json, hooks.json, .mcp.json, .lsp.json, settings.json
3	LICENSE*	License files

Step 2: If Glob results are sparse (< 5 files found), run additional Glob calls (never Bash):

Glob("*", path: {target-directory})
Glob("**/*", path: {target-directory})

Then run targeted Glob on discovered directories (e.g., skills/**/*, agents/**/*, commands/**/*).

Step 3: Classify results into component types:

Component	Path pattern
Skill	skills/*/SKILL.md
Skill auxiliary	skills/*/* (non-SKILL.md)
Agent	agents/*.md
Command	commands/*.md
Rule	rules/*.md or root-level RULE.md
Hook config	hooks/hooks.json or hooks/*.json
MCP config	.mcp.json
LSP config	.lsp.json
Config	settings.json (plugin root)
Plugin manifest	**/plugin.json

Build a component inventory with counts and file lists.

Step 4: Determine platform from Glob results (no additional Glob calls needed).

Check the file list from Step 1 for platform-unique signals:

Platform	Unique signals (any match → detected)
Claude Code	.claude-plugin/plugin.json, CLAUDE.md, .claude/ directory, agents/*.md, hooks/hooks.json, .mcp.json
Codex (not yet supported)	.codex/ directory, AGENTS.md, agents/*.toml

If no known platform is detected, ask the user: "Could not detect the agent platform. Currently supported: Claude Code. Is this a Claude Code plugin?"

If Codex is detected, inform the user that Codex analysis is not yet supported.

Set {platform} variable for subsequent phases. Currently only claude-code is implemented.

Phase 3: Metadata Collection

Why: Reading identity files here avoids duplicate reads inside sub-agents, saving tokens.

Read identity files in a single message with parallel Read calls:

• plugin.json (or .claude-plugin/plugin.json — whichever Phase 2 found)
• hooks/hooks.json (only if found in Phase 2)

Existence of LICENSE, CHANGELOG.md, tests/ is already known from Phase 2.

Do NOT read README.md, SKILL.md, agent.md, command.md, or hook script files. Sub-agents read these files directly — the feature-architect reads README.md in its own analysis procedure. Reading them here wastes tokens through duplication.

Output for Phase 4: plugin identity + file path inventory + existence flags + language.

Phase 4: Parallel Analysis

Why: Feature and security analysis are independent concerns — parallel execution halves wall-clock time.

For overview mode, skip this phase — go directly to Phase 5.

For analyze and security modes, delegate to agents in parallel.

Agent prompt: Provide each agent with:

• Plugin identity (name, version, author, description — from plugin.json)
• Target directory path
• Component file paths grouped by type (from Phase 2 Glob)
• Output language
• Analysis mode
• Source context: source_type, source_base, github_url (if applicable) — so feature-architect can include relative paths that the orchestrator will later combine with source_base for links

For analyze mode with large plugins (total components > 15) — split feature-architect into batches.

Count total = skills + agents + commands. Split each type in half:

S = number of skills, A = number of agents, C = number of commands

Task(subagent_type: "vision-powers:feature-architect", prompt: {
  skills 1..ceil(S/2) + agents 1..ceil(A/2) + commands 1..ceil(C/2)
})
Task(subagent_type: "vision-powers:feature-architect", prompt: {
  skills ceil(S/2)+1..S + agents ceil(A/2)+1..A + commands ceil(C/2)+1..C + MCP + LSP
})
Task(subagent_type: "vision-powers:security-auditor", prompt: {all file paths})

MCP, LSP, hooks, and rules are lightweight — keep them in Batch 2 only. All three tasks run in parallel. Merge feature-architect batch results before Phase 5.

For analyze mode with standard plugins (total components <= 15):

Task(subagent_type: "vision-powers:feature-architect", prompt: {all file paths})
Task(subagent_type: "vision-powers:security-auditor", prompt: {all file paths})

For security mode — launch only security-auditor:

Task(subagent_type: "vision-powers:security-auditor", prompt: {all file paths})

Phase 4.5: Environment Fit Diagnosis (analyze mode only)

Why: Even a well-built plugin can be wrong for the user's environment. This step catches conflicts, redundancies, and budget overruns before they cause confusion.

Diagnose whether this plugin is a good fit for the user's current environment — not just "can it run?" but "should it be installed here?"

Full procedure: Read references/platforms/claude-code/env-fit-diagnosis.md for the detailed 5-step process covering:

1. Extract plugin characteristics from feature-architect output (including rules, CLAUDE.md @imports, bundle source)
2. Run the environment scan script (env-fit-scan.js) — collects installed plugins, skills, commands, hooks, MCP servers, context metrics
3. Perform eight diagnostic analyses:
   • Via script data (steps 3A-3E, 3H): installation status, dependency check, context budget, functional overlap, hook impact, component dependencies
   • Via orchestrator (steps 3C extras, 3F, 3G): rules context cost (from feature-architect's rules analysis), CLAUDE.md @import chain, scope impact analysis, bundle source detection (from Phase 1 source context and plugin cache inspection)
4. Determine overall verdict (RECOMMENDED / CONDITIONAL / REDUNDANT / CONFLICTING)
5. Build diagnosis data structure for Phase 5/5R (includes scope_impact, bundle_source, and enhanced context_budget with always-loaded/deferred breakdown)

The environment scan script provides baseline data:

Bash(node {plugin-root}/scripts/env-fit-scan.js --plugin-name {plugin-name})

The orchestrator then supplements with:

• Rules context cost: Count rules from feature-architect output, classify as always-loaded (no paths:) or on-demand (paths: present), estimate tokens as file_size / 4
• Scope impact: All marketplace plugins install globally; check for framework-specific hooks/MCP that may warrant per-project activation
• Bundle source: Determine from Phase 1 source_type (local/github) or plugin cache path patterns (marketplace/symlink)

Save the combined environment_fit data for Phase 5/5R. Omit empty categories.

Phase 5: Report Assembly (inline markdown)

For security mode, overview mode, or analyze mode with --format md — assemble inline markdown report:

Assemble the report using references/platforms/claude-code/report-template.md format:

• overview mode: Identity + Component Inventory sections only
• security mode: Security-focused report with risk summary, permission matrix, findings
• analyze mode (--format md): Full report with analysis, Environment Fit Diagnosis, Skill Design Quality, and Plugin Profile

For Plugin Profile and Skill Design Quality, apply criteria from references/platforms/claude-code/analysis-criteria.md. For risk levels, apply rules from references/platforms/claude-code/security-rules.md. Environment Fit Diagnosis is a standalone section between Feature Deep Dive and Usage (not part of Plugin Profile). Include the full diagnosis from Phase 4.5: verdict, context budget (200K/1M scenarios), installation status, dependency check, overlap/trigger findings, hook impact, component dependencies, and recommendations. Skill Design Quality includes: skill category distribution, per-skill design assessment (description quality, progressive disclosure, gotchas, scripts, hooks, data persistence, maturity level), and improvement recommendations. This data comes from the feature-architect's Skill Design Quality output.

Output the report in the detected language, using references/platforms/claude-code/report-template.md format. Translate all section headers, labels, and descriptions to the target language. Keep component names, file paths, and technical terms (CRITICAL, HIGH, MEDIUM, LOW) untranslated.

Output the report directly to the user (inline markdown).

Phase 5R: HTML Report Generation (analyze mode — default format)

For analyze mode with HTML format (the default), generate a self-contained HTML file.

1. Determine output path:

   Default output path: ${CLAUDE_PLUGIN_DATA}/reports/{YYYY-MM-DD}-{plugin-name}-report.html

   Where:

   • {YYYY-MM-DD} is today's date (e.g., 2026-03-14)
   • {plugin-name} is from plugin.json name field (or directory name if no plugin.json)

   The Write tool creates parent directories automatically — no mkdir needed.

   Existing report check: Before generating, use Glob to search for *-{plugin-name}-report.html in ${CLAUDE_PLUGIN_DATA}/reports/. If any exist, use AskUserQuestion:

   Found existing report(s) for {plugin-name}:

   • {filename1}

   • {filename2}

   1. Create new report ({today's date})
   2. Update {most-recent-filename}

   (Translate to output language.)

   • If user chooses "create new" → use the default dated path
   • If user chooses "update" → use the existing file path as output
   • If no existing reports found → proceed with default dated path without asking

2. Resolve paths and read references:

   • Template: resolve ../../templates/agent-extension-visual.html to absolute path
   • JSON schema: resolve references/sections-data-schema.md to absolute path
   • Font system: resolve ../../references/design-system/font-system.md to absolute path
   • Anti-slop rules: resolve ../../references/design-system/anti-slop-rules.md to absolute path
   • Render script: resolve ../../scripts/render-sections.js to absolute path
   • Assembler script: resolve ../../scripts/assemble-report.js to absolute path
   • Shared directory: resolve ../../shared/ to absolute path

   Read 3 reference files in a single parallel Read call:

   1. JSON schema (references/sections-data-schema.md)
   2. Font system (../../references/design-system/font-system.md)
   3. Anti-slop rules (../../references/design-system/anti-slop-rules.md)

   Save their content for step 4. Do NOT read the template, assembler, render script, or shared directory — those are passed as paths.

3. Create sections temp directory: The sections directory path: /tmp/agent-extension-visual-{dirname}-sections/ (reuse the same {dirname} from Phase 1 if GitHub clone, or generate one for local sources) The JSON data file path: /tmp/agent-extension-visual-{dirname}-sections/sections-data.json No mkdir needed — Write auto-creates directories, and render-sections.js creates the sections dir.

4. Delegate to visual-report-writer agent (JSON mode):

   Task(subagent_type: "vision-powers:visual-report-writer", prompt: {
     **Output mode: JSON**
     Write a single file: {sections-data-json-path}
   
     feature-architect analysis results (full text, including Plugin Summary, Raw Content Excerpts, and Skill Design Quality),
     security-auditor analysis results (full text),
     plugin metadata (name, version, author, license, keywords, description),
     output language,
     JSON schema content (full text read in step 2),
     font system content (full text read in step 2),
     anti-slop rules content (full text read in step 2),
     report title: "Agent Extension Visual: {plugin-name}",
     aesthetic hint: "Editorial",
     source context: { source_type, source_base, github_url (if applicable) },
     environment fit diagnosis: { verdict, verdict_summary, installation_status,
       context_budget: {
         always_loaded: { skill_descriptions, rules, claude_md, total_tokens },
         deferred: { mcp_tools, zero_cost_skills, on_demand_rules, total_tokens },
         rows (backward compat — render script uses always_loaded/deferred when available),
         hook_injection },
       dependency_check, overlap_findings, trigger_collisions,
       hook_impact: { current, adding, projected, types, event_collisions, severity },
       component_deps,
       scope_impact: { installation_scope, affected_scopes, scope_conflicts, appropriateness },
       bundle_source: { type, identifier },
       recommendations } (from Phase 4.5; when RECOMMENDED with no findings, pass minimal verdict-only data),
     skill design quality: { category_distribution, design_assessment[], summary }
       (from feature-architect's Skill Design Quality output; include in Plugin Profile section)
   })
   

   Pass the file contents read in step 2, not paths. This eliminates the agent's read turn. The agent writes a single sections-data.json file (1 Write call instead of ~13 in HTML mode).

   Do NOT background this agent. Plugin-defined agents silently ignore permissionMode, so the visual-report-writer needs user approval for the Write call. Backgrounded agents cannot prompt for permissions and will fail silently. Always run in the foreground.

5. Render sections — convert JSON data into HTML section files + metadata.json:

   Bash(node {render-script-path} --data {sections-data-json-path} --output {sections-dir})
   

   This script produces section-1.html through section-11.html and metadata.json with correct CSS class names hardcoded. No LLM-generated class names.

6. Assemble report — run the assembler script to combine template + sections:

   Bash(node {assembler-path} --template {template-path} --sections {sections-dir} --metadata {sections-dir}/metadata.json --shared {shared-dir-path} --output {output-path})
   

7. Report validation — run the validation script:

   Bash(node {validator-path} {output-path} --expected-sections 11)
   

   {validator-path} = {plugin-root}/scripts/validate-report.js

   The script checks: unreplaced placeholders (section + metadata), section content density, Mermaid diagram-type keywords, Chart.js data arrays, and section count. It exits 0 on PASS, 1 on FAIL with a list of issues.

   If FAIL: fix the reported issues via Edit on the output file, then re-run the script until PASS.

   Optional Coherence Review — if --verify flag was specified or auto_verify is true in user config: Run the coherence review agent (see ../../references/report-generation-workflow.md Step 6). If HIGH severity issues are found, fix them via Edit and re-validate.

   Optional Chrome visual verification — only if --verify flag was specified AND mcp__claude-in-chrome__* tools are available. Skip entirely otherwise:

   1. Start a local HTTP server to serve the report (Chrome extensions cannot access file:// URLs):

      Bash(python3 -m http.server 0 -d "$(dirname {output-path})" 2>&1 & echo $!)
      

      Capture the PID and port from the output.
   2. Call tabs_context_mcp (with createIfEmpty: true) to get or create an MCP tab group.
   3. Use navigate to open http://localhost:{port}/{filename} in the MCP tab.
   4. Use javascript_tool to check for Mermaid render errors (document.querySelectorAll('.mermaid svg').length) and empty sections.
   5. Fix any issues found via Edit on the output file.
   6. Kill the server: Bash(kill {pid} 2>/dev/null)

8. Report completion + Feedback Loop:

   Use AskUserQuestion with the file:// URL embedded in the question text itself:

   Report generated: [Open Report](file://{output-path})
   
   Review the report. Each section has a ✎ button — write feedback and click **Save**.
   When done, click **"Copy to Clipboard"** at the bottom bar and paste here.
   Or just tell me what to change directly.
   

   (Translate to output language. {output-path} is the actual path determined in step 1. Always include the file:// URL as a markdown link — this is how the user opens the report.)

   • If the user pastes exported feedback JSON → parse it and apply changes to sections with status: "issue". Do NOT read the full HTML file — only Edit the specific sections that need changes. This prevents context bloat.
   • If the user describes changes in natural language → apply modifications via targeted Edit calls on the HTML file
   • After applying changes, ask again with the same URL
   • If the user confirms completion → proceed to Phase 7

Phase 7: Cleanup

Clean up temporary files:

Bash(rm -rf /tmp/agent-extension-visual-{dirname}-sections)

If the source was also cloned from GitHub:

Bash(rm -rf /tmp/agent-extension-visual-{dirname})

After cleanup, suggest optional next steps:

• /fact-check — verify the report's factual accuracy against the actual codebase
• /report-manager refine — refine specific sections based on feedback
• --verify — if not used this time, mention that coherence review is available for future runs

This is informational — just a brief suggestion, not an automatic invocation.

Gotchas

• GitHub URL analysis requires gh CLI: gh repo clone is used for source acquisition from GitHub URLs. If gh is not installed or not authenticated, GitHub URL analysis will fail. Local path and installed plugin analysis work without gh.
• $() command substitution triggers security prompt: The Bash(echo $(date)) pattern causes Claude Code to show a separate permission dialog regardless of allowed-tools. Use literal values or Bash(date) with separate processing instead.
• GitHub rate limiting: gh repo clone and gh api calls can fail silently with HTTP 403 when the user's token is rate-limited. If clone fails, check gh auth status before retrying.
• Plugin cache has multiple versions: ~/.claude/plugins/cache/ stores every installed version (e.g., 2.6.0/, 2.7.1/). Phase 4.5 uses the session context directly (not cache scanning), but if you ever need to inspect the cache manually, always pick the latest version per plugin to avoid counting stale entries.
• Large plugin batching threshold: The 15-component threshold for splitting feature-architect is approximate. Plugins with many small commands but few skills may not need splitting, while plugins with 10 dense skills might. Use judgment — the goal is keeping each agent under context limits.
• Existing report overwrite prompt: The "create new or update" prompt uses AskUserQuestion. If the user is running non-interactively or in a pipeline, this blocks. Default to "create new" if no user response is available.
• Temp directory collision: The 8-char hex {dirname} has a negligible collision risk, but if a previous run crashed without cleanup, /tmp/agent-extension-visual-* directories may linger. The cleanup phase handles the current run only — it does not garbage-collect stale dirs.
• Skill category misclassification: Skills that span multiple categories (e.g., a deploy skill with review features) should be classified by primary purpose — what the user invokes it for. Don't try to assign multiple categories; pick the best fit and note the overlap in the description.
• Design quality false negatives: A skill with no scripts/ directory isn't necessarily "Basic" — some skills genuinely don't need scripts (pure knowledge/reference skills). Apply the N/A classification for criteria that don't apply to the skill type.
• New hook events: The security-auditor knows about 22 hook events as of 2026-03. If new events are added to Claude Code, the event list in security-rules.md and security-auditor.md may need updating.
• Do not background visual-report-writer: Plugin-defined agents silently ignore permissionMode, so backgrounding visual-report-writer prevents Write permission prompts from reaching the user, causing silent failure. Always run in foreground.
• Plugin agent ignored frontmatter fields: permissionMode, hooks, mcpServers are silently ignored on plugin agents. The fields effort, model, tools, disallowedTools, maxTurns, skills, memory, background, isolation work normally. Analysis agents use effort: high and inherit the session model.
• Agent effort field: The effort field (low/medium/high/max) is distinct from the model field. A Haiku agent with effort: max is different from an Opus agent with default effort. Report both when present.
• Instruction layer analysis false positives: Step 10 of the security-auditor analyzes SKILL.md body text for adversarial patterns (env var exfiltration, obfuscation, undeclared URLs). Setup/config skills that reference env var names as documentation, API skills with endpoint URLs, and encoding skills with base64 examples will trigger pattern matches. Context Modifiers handle common cases, but review flagged findings carefully — a MEDIUM on a config skill's env var reference is usually informational, not a real threat.
• Mermaid node labels with special chars: Node labels containing :, /, <, > must be double-quoted in Mermaid code (C1["gsd:new-project"] not C1[gsd:new-project]). Unquoted special chars cause Mermaid parsing errors and can produce oversized layouts. The render script auto-quotes these, but the visual-report-writer should generate quoted labels to begin with.
• Command-based plugins and empty Skill Design Quality: Plugins built on commands/ instead of skills/ will have empty skill_design_quality arrays and missing features/KPIs. The render script skips empty sections gracefully, but the visual-report-writer should adapt its analysis for command-based plugins rather than leaving fields empty.
• security_summary as object: The visual-report-writer sometimes passes security_summary as a JSON object (with risk_level, findings_by_severity, positive_features) instead of a plain string. The render script handles both formats, but a string summary is preferred.
• LLM schema mismatches handled by normalize: The render-sections.js normalize function auto-corrects 15 common LLM output variations. Do NOT write Python fixup scripts in Bash — the normalize layer handles these deterministically. Key patterns: features as [{title, description}] → string[], recommendations as [{priority, text}] → string[], keywords as array → comma-separated string, installation_status as string → {status, detail}, dependency_check missing status/severity, philosophy cards with empty name, chart labels by purpose instead of extension type, workflow_trace title leading numbers stripped, and context_budget empty budget columns filled with official doc values.
• Architecture diagrams with large plugins: Plugins with 15+ components cause the LLM to list all nodes individually, producing broken Mermaid layouts or "...N more" truncation. The schema now instructs showing 3-5 representatives per architectural layer with total counts, keeping under 25 nodes per diagram.
• Overview chart must use extension types: The chart labels must be extension types (Skills, Agents, Commands, Hooks, MCP, LSP) not purpose categories (Scaffolding, Automation, etc.). The normalize function auto-corrects this by counting from the components section, but the schema also instructs this explicitly.
• Never Read the full HTML report for feedback: The generated HTML report can be 10,000+ tokens. Reading it into context for feedback processing causes context bloat and slow responses. Instead, use the Export Feedback JSON (a few hundred tokens) or have the user describe changes verbally. When edits are needed, use targeted Edit calls on specific line ranges — never Read the entire file.
• Do not edit Mermaid diagrams directly in the final HTML: Mermaid code in the assembled HTML is inside <pre class="mermaid"> blocks. Editing these directly risks syntax errors that break rendering (e.g., missing quotes on node labels, invalid subgraph syntax). If a diagram needs changes, edit the sections-data.json source and re-run render-sections.js + assemble-report.js instead.
• Discovery phase must use Glob only, never Bash: Phase 2 file discovery must use Glob calls exclusively. Bash calls like ls or find are not in allowed-tools and trigger a user permission prompt that blocks execution (observed: 185s wait). All file listing needs are covered by Glob patterns — there is no case where Bash is needed for discovery.
• Rules with paths: frontmatter are deferred: Rules that have a paths: field in frontmatter are NOT always-loaded — they only activate when matching file paths are in context. Treat them as zero always-on cost in context budget analysis. Rules WITHOUT paths: load their full content at session start.
• Plugin settings.json only supports agent field: A plugin's settings.json at the root level only supports the agent field for setting a default agent. It does NOT support permissions, hooks, or other settings — these are silently ignored. Don't report unsupported settings as features.
• Bundle source detection is best-effort: skills-lock.json may not exist in older installations, and cache path patterns can vary. Always fall back to plugin.json repository field or mark as unknown. Don't report missing provenance as a security issue.
• Scope impact for marketplace plugins: All marketplace-installed plugins operate at the global scope. Their hooks fire for every project. If the plugin is highly framework-specific (e.g., React, Django), note this as a scope appropriateness concern — the user may want to conditionally disable it for non-matching projects.
• Context budget empirical grounding: Context budget recommendations reference empirical estimates of ~20% structural waste in production sessions (unused tools, duplicates, stale results). Use this as motivation for context-aware recommendations, but note it's a general finding — individual plugin impact varies.
