helm-arbiterScope arbitration — resolve disagreements between product and engineering on what is in or out of scope, with a decision log and escalation path.
Helm Arbiter is an agent skill from jeremylongshore/tons-of-skills-marketplace. Scope arbitration — resolve disagreements between product and engineering on what is in or out of scope, with a decision log and escalation path. Use when asked to "resolve this scope disagreement", "arbitrate between product and eng", "scope is creeping", "we can't agree on what's in scope", or "help us decide what to cut".
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `.claude-plugin/plugin.json`).
It sits in DevOps & Cloud, covering Container orchestration, Dispute resolution and Architecture decision records. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditBashGlobGrepWebFetchWebSearchTaskTodoWrite…and 1 more on the same allowed-tools line.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Helm Arbiter loads about 1.1k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 409 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
allowed-tools: Read, Write, Edit, Bash, Glob, Grep, WebFetch, WebSearch, Task, TodoWrite, AskUserQuestionAutomated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Clarify the exact nature of the scope dispute. Ask or identify:
Do not mediate before you understand all four inputs.
Identify which type of disagreement this is:
| Type | Description | Resolution approach |
|---|---|---|
| Scope creep | New item not in original brief | Evaluate against success criteria |
| Estimation conflict | Product thinks it's easy; eng thinks it's hard | Get Apex cost estimate |
| Priority conflict | Both sides agree it's needed, disagree on when | Apply RICE to the item |
| Definition conflict | Different understandings of what the feature does | Write a precise spec |
| Risk conflict | Eng has concerns product didn't account for | Surface and evaluate the risk |
For the contested item, evaluate:
Against success criteria (from the Helm brief):
Against constraints (from the Helm brief):
The 50% rule: If an item takes more than 50% of remaining engineering budget but contributes less than 50% of user value, cut it.
Present exactly three options:
Option A — Include as specified
Engineering cost: [S/M/L — use Apex estimate if available]
Product value: [why this delivers the stated goal]
Risk: [what could go wrong]
Option B — Include a reduced version
What's included: [specific subset]
What's cut: [what gets dropped and why it's acceptable]
Engineering cost: [S/M/L]
Value retained: [% of original value, roughly]
Option C — Defer entirely
Condition for revisit: [what signal would bring this back]
Impact of deferring: [what users lose, what metrics are affected]
Engineering savings: [what the team gains by cutting this now]Once both sides agree, record the decision:
## Scope Decision Log
Item: [contested feature or requirement]
Date: [today]
Decision: [Option A / B / C]
Rationale: [1-2 sentences — why this option was chosen]
Condition for reopening: [what would change this decision]
Agreed by: [Helm + Apex, or Helm + eng lead]Add this log entry to project brief or sprint planning doc.
Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.
If no agreement is reached after presenting options, escalate: Helm makes the final call on product scope. Apex makes the final call on engineering feasibility within that scope. These domains do not overlap.
If output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.

Scope arbitration — resolve disagreements between product and engineering on what is in or out of scope, with a decision log and escalation path. Helm Arbiter is an agent skill from jeremylongshore/tons-of-skills-marketplace. Scope arbitration — resolve disagreements between product and engineering on what is in or out of scope, with a decision log and escalation path.
Helm Arbiter fits situations like: asked to resolve this scope disagreement; arbitrate between product and eng; scope is creeping; we cant agree on whats in scope.
Run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill helm-arbiter -a claude-code`. Or copy the skill folder (plugins/ai-agency/tonone/skills/helm-arbiter in jeremylongshore/tons-of-skills-marketplace) into .claude/skills/helm-arbiter in your project. Claude Code loads it when a task matches its description.
Run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill helm-arbiter -a codex`. Or copy the skill folder (plugins/ai-agency/tonone/skills/helm-arbiter in jeremylongshore/tons-of-skills-marketplace) into .agents/skills/helm-arbiter in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill helm-arbiter -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/helm-arbiter, .gemini/skills/helm-arbiter, .github/skills/helm-arbiter and .opencode/skills/helm-arbiter in your project.
SKILL.md names no scripts, command-line tools or credentials: Helm Arbiter is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Write, Edit, Bash, Glob, Grep, WebFetch, WebSearch, Task, TodoWrite, AskUserQuestion.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Helm Arbiter is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.1k tokens (SKILL.md is roughly 4.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
