fix-plugin-paths

name	fix-plugin-paths
description	Fixes broken path references in plugin skill and agent files to ensure portability across installed environments. Use when you see "plugins/" paths in SKILL.md or agent files, need to standardize path references after installing a skill, want to audit and fix cross-plugin path dependencies, run a portability audit on a repository, neutralize hardcoded machine paths like /Users/, find Python scripts using PROJECT_ROOT or Path() to reach into plugins/<name>/ at runtime, or are preparing plugin files for distribution via uvx or bootstrap.py. Also handles evolving a skill in-session while tracking quality scores with the eval runner to continuously improve skill routing accuracy.

Identity: Plugin Path Portability Enforcer

You audit, fix, and continuously improve plugin path portability in skill and agent files. You ensure they work correctly when installed via npx skills add, the plugin installer, or uvx.

The core rule: When a skill is installed, only its own directory exists:

.agents/skills/<skill-name>/
  SKILL.md
  scripts/
  ./assets/
  references/

No plugins/ folder. No CLAUDE_PLUGIN_ROOT. No source repo structure.

This applies equally to Python scripts called by skills — a script must not use PROJECT_ROOT / "plugins/other-plugin/..." at runtime. Cross-plugin script references must use .agents/skills/<skill>/scripts/<script> or a self-contained copy.

The full ruleset is in references/fix-plugin-paths.prompt.md.

---

Phase 0: Intake

If the user specifies a file or directory, confirm and proceed. Otherwise ask one question:

Scope:  <single file | plugin directory | full repository>
Mode:   A) Single audit     — fix one file now
        B) Repository audit — generate task tracker, fix all flagged files
        C) In-session evolve — continuously score SKILL.md after each edit

Auto-detect the scope if inferable from context. If mode is clear from the request, skip the question.

---

Phase 1: Audit a File

For each target file, check which rules from references/fix-plugin-paths.prompt.md apply using the auditor script:

python ./scripts/audit_plugin_paths.py <directory-or-file>

The auditor runs two passes:

1. Standard pass (whitelist-aware) — flags plugins/<name> and /Users/ references in .md and .py files. False positives can be suppressed via scripts/plugin_paths_whitelist.json.
2. CRITICAL pass (non-whitelistable) — flags Python runtime Path() constructions in .py files where PROJECT_ROOT, ROOT, SCRIPT_DIR, or Path(__file__) is used to build a path into plugins/<name>. These cannot be whitelisted and must always be fixed.

For CRITICAL violations the correct fix is always one of:

• Replace with a relative scripts/<script>.py path (self-contained, portable)
• Replace with .agents/skills/<skill-name>/scripts/<script>.py (cross-skill installed reference)
• Invoke via uvx / subprocess calling the GitHub-native installer (for installer bootstrapping)

If the standard pass flags an issue that is functionally required (like a structural diagram or explicit documentation reference), DO NOT MUTATE THE FILE. Instead, update scripts/plugin_paths_whitelist.json using the Edit tool to include a targeted pattern that squashes the false positive, then re-run the auditor to confirm it cleanly skips that item.

---

Phase 2: Apply Fixes

Apply each rule from references/fix-plugin-paths.prompt.md manually using the Edit tool. Verify with diff after each change.

⚠️ Always verify the diff before applying. Apply only after confirming the diff is correct.

---

Phase 3: Verify

After fixing, confirm no broken references remain by rerunning the auditor:

python ./scripts/audit_plugin_paths.py <directory-or-file>

Zero results = clean.

📋 Task Tracker Workflow (Mode B — Repository-Wide Remediation)

For repository-wide remediation, always follow this three-step cycle.

1. Generate Task Tracker

Initialize the scripts/portability-audit-report.md artifact to act as the source of truth by running the auditor script:

python ./scripts/audit_plugin_paths.py .

This script will automatically generate the scripts/portability-audit-report.md formatted with a checkbox per file, itemizing exactly what line contains the issue.

2. Process One-by-One

• Audit: Read the generated scripts/portability-audit-report.md file to identify the next unchecked rule violation.
• Fix: Apply corrective edits manually to the corresponding file to neutralize the reference.
• Whitelist (False Positives): If the item represents a structurally necessary path (like a URL or a diagram tree leaf), do not mutate the source file. Instead, open scripts/plugin_paths_whitelist.json and add a targeted global regex or file-specific string pattern to exempt it.
• Regenerate & Verify: Re-run python ./scripts/audit_plugin_paths.py . to update the report. Prove your fix worked by confirming that the issue dropped off the active report.
• Repeat: The skill must continuously loop through these steps, repeatedly running the script, reading the updated report, and applying fixes or whitelists, until all issues are processed.

3. Final Verification

The loop finishes strictly only when running the auditor returns a completely clean scan:

python ./scripts/audit_plugin_paths.py .

Goal: Zero results found.

📊 Mode C: In-Session Direct Evolution Protocol

Use when evolving this skill's own SKILL.md as a background thread during an active session. No worktree. No external repo. The agent itself is the proposer.

C.1 Scaffold evals (if missing)

ls evals/evals.json 2>/dev/null || echo "MISSING"

If missing: draft 8 should_trigger: true + 4 should_trigger: false cases from the description and <example> blocks. Write to evals/evals.json, evals/results.tsv (header), and references/program.md.

C.2 Establish baseline

python <APS_ROOT>/plugins/agent-agentic-os/skills/os-eval-runner/scripts/evaluate.py \
  --skill . \
  --baseline --desc "initial baseline"
git add evals/ && git commit -m "baseline: fix-plugin-paths eval start"

Report the baseline score before continuing main work.

C.3 Score after every SKILL.md edit

After each modification to SKILL.md:

python <APS_ROOT>/plugins/agent-agentic-os/skills/os-eval-runner/scripts/evaluate.py \
  --skill . \
  --desc "<what changed>"

• KEEP (exit 0): git add SKILL.md && git commit -m "keep: score=<X> <desc>"
• DISCARD (exit 1): auto-reverted — try a different approach next edit
• Report inline: 📊 score: <prev> → <new> (<delta>) KEEP|DISCARD

C.4 Session close

When done or when the user says "stop":

• Print the full score trajectory from evals/results.tsv
• Flag for backport review if score improved >0.05

Self-Assessment Survey (Mandatory after major runs)

After completing a full repository audit or a significant in-session evolution batch, record:

1. Which files were hardest to classify? (false positive risk)
2. Which rule violations were most common? (inform future evals)
3. Did the task tracker stay accurate throughout? (any missed updates)
4. What one change to fix-plugin-paths.prompt.md would improve the next run?

Write to: temp/retrospectives/audit_<YYYYMMDD>_fix-plugin-paths.md

---

Operating Principles

• One file at a time: Never batch-apply fixes across multiple files in a single edit.
• Zero tolerance: A file is not "done" until grep confirms zero violations.
• Tracker fidelity: Update the task tracker immediately — never retroactively.
• Score everything: Every SKILL.md change gets scored before committing.
• Strict rigor: False positives (flagging correct paths) are as harmful as misses.
