maintain

A recurring procedure for updating project dependencies, applying security fixes, and managing package versions. Dependencies are external libraries and tools that a codebase relies on.

In plain words
What is it for?
Use it to check for outdated packages, apply suitable updates, infer the package manager from lock files, and record the maintenance results.
Why use it?
It reduces the risk of known security problems, outdated packages, and difficult future upgrades building up unnoticed.

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.

Security

Grade A, and why

maintain 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 2d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Dependency Maintenance — Stage 9

Read the detailed guide at ${CLAUDE_SKILL_ROOT}/references/maintain-detailed-guide.md for the complete maintenance procedures, teammate spawn prompts, update strategies, and report templates.

Context

Designed to be run on a regular cadence (monthly or quarterly) to keep the codebase healthy. Outdated dependencies accumulate security vulnerabilities, miss performance improvements, and eventually create painful migration cliffs.

Prerequisites

  1. Read CLAUDE.md and plancasting/tech-stack.md.
  2. Ensure git status shows a clean working directory. Commit or stash all uncommitted changes.
  3. Check plancasting/tech-stack.md for the Session Language setting. Generate all reports in the specified language.
  4. Infer package manager from lock files if CLAUDE.md Part 2 'Commands' section is empty: bun.lockb -> bun, package-lock.json -> npm, pnpm-lock.yaml -> pnpm. Log the inferred package manager in the report.

Inputs

  • Codebase: Complete project directory
  • Tech Stack: ./plancasting/tech-stack.md
  • Project Rules: ./CLAUDE.md
  • Lock file: package-lock.json, bun.lockb, or pnpm-lock.yaml

Stack Adaptation

Examples use bun commands. Adapt to your package manager:

  • npm audit -> Bun has no built-in audit. Use npm audit if package-lock.json exists; otherwise use bunx audit-ci or npx snyk test. Document which audit tool was used in the report.
  • npm update -> bun update
  • npm outdated -> bunx npm-check-updates (Bun has no built-in outdated command) Always read CLAUDE.md and plancasting/tech-stack.md for actual conventions.

Execution Flow

Phase 1: Lead Analysis and Planning

Branch safety: Create a dedicated branch: git checkout -b chore/dependency-update-$(date +%Y-%m-%d-%H%M%S). The HMS suffix prevents collisions if Stage 9 is re-run the same day. Do NOT commit directly to main.

Pre-flight Concurrency Check: Before proceeding, verify that Stage 8 (Feedback Loop) is not currently in progress. Check: (1) git log --oneline -5 | grep -i 'feedback' — if the most recent commit is an in-progress feedback batch from the current day, STOP; (2) git branch --list 'feedback/*' — if a feedback/batch-* branch exists, Stage 8 may be active. Do not run Stage 9 concurrently with Stage 8 (both modify package.json and lock files). Wait for Stage 8 to complete and commit before starting Stage 9.

Files

What ships with it

1 file 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.

maintain is a skill published in the GitHub repository VoxTechnologies/transmute-framework (4 stars, last pushed 1mo ago), licensed MIT. It adds 86 tokens to every session and 3,810 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
