long-horizon-prompting

This skill should be used when writing, enhancing, or evaluating the launch prompt for a long-running autonomous agent or a parallel multi-agent orchestration attacking a hard problem: pseudo-formal task briefs that define terms and an exact success predicate linguistically, enumerate non-counting outcomes, set persistence rules with explicit stop and return conditions and effort floors, manage a diverse portfolio of parallel approaches with an approach registry and blocked-route bookkeeping, and gate the return on adversarial audit. Route agent topology and coordination protocols to multi-agent-patterns, runtime control surfaces and loop governance to harness-engineering, evaluator and quality-gate construction to evaluation, judge design to advanced-evaluation, and compaction or memory mechanics to context-compression and memory-systems.

Quality

Content

85%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A highly actionable, well-structured body: concrete workflows, worked examples, explicit validation gates and feedback loops, and clean one-level reference hygiene. The main weakness is redundancy — the Guidelines and Gotchas sections re-encode the Core Concepts and Verification sections at length, inflating token cost without adding new guidance.

Suggestions

Merge the 18-item Guidelines and 14-item Gotchas sections into a single consolidated quick-reference: roughly a third of their items restate Core Concepts verbatim (e.g., persistence-with-verification-gate appears in 'Persistence Cuts Both Ways', Guideline 5, and Gotcha 3).

Deduplicate the non-counting-outcomes/near-miss guidance, which is explained six times across Core Concepts, the anatomy table, the workflow, the pre-launch checklist, Guidelines, and Gotchas; keep the Core Concepts treatment and one-line pointers elsewhere.

Move the itemized restatements in 'Stop Conditions, Effort, and Progress State' and 'Lean and Outcome-First' that repeat Gotcha 8 and Gotcha 10 into the relevant reference files (research-evidence.md, vendor-guidance.md) to cut body length.

DimensionReasoningScore

Conciseness

The body is dense, expert-level, and free of explanations of concepts Claude already knows, but the 18-item Guidelines and 14-item Gotchas sections substantially restate the Core Concepts sections — the persistence-with-verification-gate rule appears four times and non-counting outcomes are explained in six places. Not 4: the repetition is more than minor over-explanation; not 2: there is no padded fluff and nearly all content is novel, non-obvious guidance.

3 / 5

Actionability

Fully actionable for an instruction-only skill: a 9-step Brief-Writing Workflow, three worked weak-to-strong examples (brief skeleton, root-cause-analysis brief, typed handoff contract with fields like "no_future_leakage: bool" and "VERIFY: <split-check command>; paste its output"), and a 13-question pre-launch evaluation checklist. Specific examples cover the common cases. Not 4: the guidance is copy-paste adaptable with only intentional template placeholders.

5 / 5

Workflow Clarity

Clear sequences with explicit validation and feedback loops: workflow step 9 ("Red-team the brief before launch: ask a fresh model instance 'what is the cheapest way to make this look done...' and patch every answer... Stop when a pass finds only near misses that are already excluded"), the pre-launch rule "Any 'no' is a defect to fix, not a judgment call", and recall loops ("Route a failed check back to the responsible worker... with acceptance criteria, and a retry cap") plus "Run each check once on a known-bad input". This is not a destructive/batch skill, so no validation cap applies.

5 / 5

Progressive Disclosure

Clear overview with well-signaled, one-level-deep references, all five of which exist on disk (cdc-prompt-annotated.md, vendor-guidance.md, research-evidence.md, task-brief-template.md, mass-handoff-contracts.md). Detail is appropriately split: the full annotated CDC prompt, dated vendor extracts, and MASS contract details live in references, signaled inline at point of use ("The annotated workflow... are in [the MASS reference](./references/mass-handoff-contracts.md)") and summarized with one-line descriptions in the References section.

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: explicit trigger clause, multiple concrete capabilities, and active routing that sharply reduces mis-trigger risk against sibling skills. The only weakness is trigger vocabulary that leans on internal jargon rather than natural user synonyms.

DimensionReasoningScore

Specificity

Lists multiple concrete actions with comprehensive coverage: "writing, enhancing, or evaluating the launch prompt", "define terms and an exact success predicate", "enumerate non-counting outcomes", "set persistence rules with explicit stop and return conditions and effort floors", "manage a diverse portfolio of parallel approaches", "gate the return on adversarial audit", plus routing actions to five sibling skills. Not 4: coverage of what the skill does is complete within its scope, with no gaps.

5 / 5

Completeness

Explicitly answers both: what ("pseudo-formal task briefs that define terms and an exact success predicate... and gate the return on adversarial audit") and when ("This skill should be used when writing, enhancing, or evaluating the launch prompt for a long-running autonomous agent or a parallel multi-agent orchestration attacking a hard problem"), with concrete trigger conditions and explicit when-not routing. Not 4: the when-clause is explicit, specific, and multi-conditional, matching the anchor-5 example pattern.

5 / 5

Trigger Term Quality

Good natural keywords: "launch prompt", "long-running autonomous agent", "parallel multi-agent orchestration", "hard problem", "success predicate". Not 5: several load-bearing terms are internal jargon users would not say ("pseudo-formal task briefs", "non-counting outcomes", "blocked-route bookkeeping") and common natural variations like "system prompt", "agent prompt", or "prompt engineering" are missing. Not 3: the core trigger phrases are exactly what a user preparing a long-running agent launch would say.

4 / 5

Distinctiveness Conflict Risk

Clear niche (the launch prompt for long-horizon/parallel runs) with minimal conflict risk: the description actively disambiguates by routing adjacent work away ("Route agent topology and coordination protocols to multi-agent-patterns, runtime control surfaces and loop governance to harness-engineering, evaluator and quality-gate construction to evaluation, judge design to advanced-evaluation, and compaction or memory mechanics to context-compression and memory-systems").
