Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00044 | $0.01723 |
| Opus 5 | $0.00022 | $0.00861 |
| Sonnet 5 | $0.00009 | $0.00345 |
| Haiku 4.5 | $0.00004 | $0.00172 |
Grade A, and why
finishing-a-development-branch 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 10d 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.
This is a copy
100% identical to finishing-a-development-branch — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Finishing a Development Branch
Overview
Guide completion of development work by presenting clear options and handling chosen workflow.
Core principle: Verify tests → Detect environment → Present options → Execute choice → Clean up.
Announce at start: "I'm using the finishing-a-development-branch skill to complete this work."
The Process
Step 1: Verify Tests
Before presenting options, verify tests pass:
# Run project's test suite
npm test / cargo test / pytest / go test ./...
If tests fail:
Tests failing (<N> failures). Must fix before completing:
[Show failures]
Cannot proceed with merge/PR until tests pass.
Stop. Don't proceed to Step 2.
If tests pass: Continue to Step 2.
Step 2: Detect Environment
Determine workspace state before presenting options:
GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
This determines which menu to show and how cleanup works:
| State | Menu | Cleanup |
|---|---|---|
GIT_DIR == GIT_COMMON (normal repo) |
Standard 4 options | No worktree to clean up |
GIT_DIR != GIT_COMMON, named branch |
Standard 4 options | Provenance-based (see Step 6) |
GIT_DIR != GIT_COMMON, detached HEAD |
Reduced 3 options (no merge) | No cleanup (externally managed) |
Step 3: Determine Base Branch
# Try common base branches
git merge-base HEAD main 2>/dev/null || git merge-base HEAD master 2>/dev/null
Or ask: "This branch split from main - is that correct?"
Step 4: Present Options
Normal repo and named-branch worktree — present exactly these 4 options:
Implementation complete. What would you like to do?
1. Merge back to <base-branch> locally
2. Push and create a Pull Request
3. Keep the branch as-is (I'll handle it later)
4. Discard this work
Which option?
Detached HEAD — present exactly these 3 options:
Implementation complete. You're on a detached HEAD (externally managed workspace).
1. Push as new branch and create a Pull Request
2. Keep as-is (I'll handle it later)
3. Discard this work
Which option?
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.

finishing-a-development-branch is a skill published in the GitHub repository JustMichael-80/MasterVault (12 stars, last pushed 28d ago), licensed MIT. It adds 44 tokens to every session and 1,723 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to finishing-a-development-branch, differing in 0 lines, and is treated as a copy.
Other skills, from other repositories
release-slice
Open-source one slice of a private system: take a component, sanitize it, run a leak-scan as a hard gate, publish to GitHub, then changelog, roadmap and tag on cadence, then the content wave. Publishing without passing the leak-scan is forbidden. Triggers: "/release-slice ", "ship the next slice".
finishing-a-development-branch
A workflow for closing a development branch after all work and tests are complete. A branch is a separate line of changes in a version-control system such as Git.
release-skills
A release workflow for preparing and publishing a new version of a software project. A release is a named version that may include updated version files, release notes, tags, or a GitHub Release.
version-release
Choose and apply the correct semantic version bump for this repository. Use for every user-visible release, before merge when a change set should ship as patch, minor, or major, and whenever package/plugin/desktop version metadata must stay synchronized.
git-wrapup
Land working-tree changes as logical commits — the work grouped by concern, topped by a release commit (version bump, changelog, regenerated artifacts). Verify, commit. Stops at "committed locally on main" — or, when the project releases through a release PR, at "release branch pushed, PR open". No tag, no push to…
release-and-publish
Ship a release end-to-end across every registry the project targets (npm, MCP Registry, GitHub Releases for .mcpb bundles, GHCR). Runs the final verification gate, fast-forwards main when the release rode a release PR, creates the annotated tag on the commit main now points at, pushes commits and tags, then publishes…
