skill-install-dry-run-planner

skill-install-dry-run-planner is a skill for Claude Code from wyattowalsh/agents. It costs 40 tokens per session (485 once invoked), scanned A, original, MIT.

A planning tool for synchronising skills across different agent environments. It uses a dry run to show what would be validated, missing, unresolved, skipped, or installed before any live apply step.

In plain words
What is it for?
Use it to plan a full or harness-specific sync, review dry-run gaps, optionally run an installation smoke test, and prepare the apply gate.
Why use it?
It gives maintainers a reviewable plan and a human approval point before changing installed skills.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Fable 5.1 $0.00040 $0.00485
Opus 5.5 $0.00016 $0.00194
Sonnet 5.5 $0.00008 $0.00097

Security

Grade A, and why

skill-install-dry-run-planner scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/asset_toolkit/validate_hooks.py, scripts/check.py, scripts/plan_dry_run.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Skill Install Dry-Run Planner

Produce a maintainer plan from skills-sync dry-run evidence.

Scope: Dry-run planning only. Never run live apply installs from this skill.

Dispatch

$ARGUMENTS Action
Empty Full dry-run plan for all harnesses
--harness <name> Plan for one harness adapter
--format json Machine-readable plan
help Show phases, gates, and related runbooks

Planned Phases

  1. Validate — run the repo validation command
  2. Dry-run JSON — run the skills-sync dry-run JSON command
  3. Review gaps — inspect missing, unresolved, and skipped rows per harness
  4. Optional smoke — INSTALL_SMOKE=1 temp-home phase (maintainer machine only)
  5. Apply gate — human approval required before any --apply

Also see skills/cross-agent-install-smoke/ and docs/runbooks/install-smoke.md.

Workflow

uv run python skills/skill-install-dry-run-planner/scripts/plan_dry_run.py
uv run python skills/skill-install-dry-run-planner/scripts/plan_dry_run.py --harness cursor --format json

Validation Contract

uv run python skills/skill-install-dry-run-planner/scripts/check.py

Critical Rules

  1. Default to dry-run; treat sync JSON as evidence, not authority over repo policy.
  2. Never auto-apply installs or run live npx skills add from this skill.
  3. Run phase 1 dry-run checks before recommending reconciliation.
  4. Gate temp-home smoke behind INSTALL_SMOKE=1.
  5. Document unresolved catalog rows instead of silently skipping them.
Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
