lfx-mcp: Skill for Claude Code

.agents/skills/upgrade-maintenance/SKILL.md

upgrade-maintenance is a skill for Claude Code, Codex from linuxfoundation/lfx-mcp. It costs 56 tokens per session (4,042 once invoked), scanned A, original, MIT.

A maintenance workflow for a Go project that updates dependencies, adapts code to changes in upstream LFX V2 services, and reviews query-service arguments.

In plain words
What is it for?
Use it during dependency upgrades, after upstream service changes, or for regular maintenance of the lfx-mcp codebase.
Why use it?
It gathers several upgrade checks into one process and helps catch build or API-contract problems introduced by newer versions.

Written for no agent in particular: nothing here depends on one. Also seen: positional $N argument; installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is linuxfoundation/lfx-mcp's own configuration. It tells Claude Code and Codex how to work on lfx-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything lfx-mcp configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is make build && ./scripts/test_server.sh 2>&1 | grep -i 'conflicting\|schema'.

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

upgrade-maintenance 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.

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.

Upgrade Maintenance

Perform a full upgrade maintenance pass on the lfx-mcp codebase. This covers three sequential phases: dependency upgrades, upstream contract fixes, and a query service argument review.

Phase 1 — Upgrade all dependencies

Step 1.1 — Upgrade the Go toolchain version

Compare the local toolchain version against the go directive in go.mod and update if the local toolchain is newer:

# Extract the version from the local toolchain (e.g. "go1.24.3").
LOCAL=$(go version | awk '{print $3}')        # e.g. go1.24.3
GOMOD=$(grep '^go ' go.mod | awk '{print $2}') # e.g. 1.23.0

echo "Local toolchain: $LOCAL"
echo "go.mod go directive: $GOMOD"

If the local toolchain is newer, update go.mod:

# Updates the go directive to match the local toolchain.
go mod tidy -go=${LOCAL#go}

Also update any other files that pin the Go version:

  • Dockerfile — FROM golang:X.Y.Z or FROM golang:X.Y-alpine base image.
  • .github/workflows/*.yml — go-version: fields in GitHub Actions steps.
  • Makefile — any hardcoded GO_VERSION variable.
  • AGENTS.md / README.md — version references in prerequisite tables.

After updating, verify the build still compiles with the new toolchain:

make build

If any deprecated language features or removed stdlib symbols cause errors, fix them before continuing.

Step 1.2 — Upgrade Go module dependencies

# Upgrade all direct dependencies to their latest minor/patch versions.
go get -u ./...

# Tidy the module graph (removes unused indirect deps, syncs go.sum).
go mod tidy

After running, inspect go.mod for version changes. The most impactful upgrades to watch are the github.com/linuxfoundation/lfx-v2-* packages — they regularly add, rename, or remove Goa-generated struct fields, which directly affects tool handler code in internal/tools/ and client wiring in internal/lfxv2/client.go. Phase 2 is the step that reviews these changes; if any lfx-v2-* bump lands without a same-session Phase 2 pass (e.g. it was folded into a larger commit, or maintenance was interrupted), re-run Phase 2 retroactively against that commit — see "Finding OLD and NEW" in Step 2.1.

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.

upgrade-maintenance is a skill published in the GitHub repository linuxfoundation/lfx-mcp (21 stars, last pushed 6d ago), licensed MIT. It adds 56 tokens to every session and 4,042 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
