The Fable Method: skill pack for Hermes Agent

Four Hermes Agent skills for a think, act, prove and grow problem-solving loop with an adversarial judge

What The Fable Method does

The Fable Method is a discipline layer for Hermes Agent. Rather than telling a model to be careful, it specifies what to do, in what order and when to stop. It requires artifacts at decision points, such as INTENT, AUTH, TWINS and PENDING lines that must appear in reports, and sets hard bounds: three failed verify cycles means stop, and two fruitless lookups means stop searching.

Four skills make up the loop. fable-method is the core seven-step loop: classify the ask, define done, gather evidence, decide, act surgically, verify by observation, report honestly. fable-loop is the orchestrated version, with parallel evidence subagents via delegate_task and adversarial verifier agents. fable-judge re-runs each claimed check, diffs what changed and hunts for weakened tests, false completion, scope creep and similar problems, returning VERIFIED, CAVEATS or REFUTED. fable-domain generates adapter bundles for new sectors. The repository also holds eight domain adapters, worked examples and an eval with three trap fixtures.

Key features

fable-method: seven-step loop from classifying the ask to an honest report
fable-loop: parallel evidence subagents, one plan, adversarial verifiers
fable-judge: re-runs claimed checks and returns VERIFIED, CAVEATS or REFUTED
fable-domain: generates a domain adapter, trap fixture and smoke eval
Hard stop rules such as three failed verify cycles
AGENTS.md version for other agents such as Codex, Cursor and aider

When to use it

Making an agent show evidence before it reports a task as done
Auditing finished work for weakened tests or scope creep
Adding a domain-specific adapter for a new area of work

Who it is for: Hermes Agent users who want a repeatable verification discipline for coding and multi-step tasks.

How it fits with Hermes Agent

Built for Hermes Agent: it installs as a Hermes plugin, places skills in ~/.hermes/skills/software-development/, and uses delegate_task for subagents.

FAQ

What is The Fable Method?

The Fable Method is a pack of four Hermes Agent skills that define a think, act, prove and grow loop. It forces evidence artifacts at decision points and includes an adversarial judge that re-checks claims of completed work.

Does The Fable Method work with Hermes Agent?

Yes. It is built for Hermes Agent and can be installed with hermes plugins install, or manually by copying the skill directories. A separate AGENTS.md covers other agents.

How do I install The Fable Method?

Run hermes plugins install ardhaecosystem/fable-method --enable, then bash ~/.hermes/plugins/fable-method/install.sh. The skills land in ~/.hermes/skills/software-development/.
