What it does
H Compare is an agent skill from m0n0x41d/haft. Compare two or more existing candidates under an explicit characteristic space, parity basis, and predeclared selection policy. Return constraints, trade-offs, and a non-dominated set rather than hiding the choice in one score. This skill is independent of h-frame and h-explore. Default to a conversational comparison; persist comparison artifacts only on explicit save intent or when current Work supplies a concrete operator-named or agent-inferred receiving use that needs replay. A binding choice requires a…
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. The repository describes itself as: Engineering decisions engine that know when they're stale. Frame, compare, decide — with evidence decay and parity enforcement. For Claude Code, Cursor, Gemini CLI, Codex and more.
When your agent uses it
- Agent Workflows work in your project
Example prompts
- “/h-compare”
Requirements
- Pre-approved tools (allowed-tools): Bash, Read, Grep, Glob, Agent, mcp__haft__haft_note, mcp__haft__haft_problem, mcp__haft__haft_solution, mcp__haft__haft_query
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Name the candidates and the current comparison question. An inline set is
- Draft the characteristic space before scoring. Separate
- Name what each target is a proxy for. Keep incompatible scales separate.
- Declare parity before results: comparator set, evidence window, equalized
- Declare the selection policy before scoring. Do not change it after seeing
- Evaluate one dimension across all variants before moving to another. Use
- Eliminate constraint violations, then report the non-dominated set and the
What it can do on your machine
Read from SKILL.md and the folder at commit e0c63f4. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
BashReadGrepGlobAgentmcp__haft__haft_notemcp__haft__haft_problemmcp__haft__haft_solutionmcp__haft__haft_query
From allowed-tools in the SKILL.md frontmatter.
Runs code
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.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
H Compare loads about 1.7k tokens when it runs. Until then it costs about 146 tokens; SKILL.md has 675 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.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.

Automated 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 675 words (~1,657 tokens).
“Retrieve the current source before applying the comparison distillate. For a known SourceID or UnitID, call mcphafthaft_query(action="fpf", mode="inspect", identifier="..."). Otherwise call mcphafthaft_query(action="fpf", mode="concern", query=""), then inspect the direct pattern body. Query returns source candidates, not a selected governing pattern or…”
