ln-11-opportunity-evaluatorEvaluates new product opportunities through demand, channels and economics before committing to build.
Ln 11 Opportunity Evaluator is an agent skill from levnikolaevich/claude-code-skills. Evaluates new product opportunities through demand, channels and economics before committing to build.
Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Help your AI agent finish the job: solve the right problem, keep changes focused, and show what was verified. For Claude Code and Codex. The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 0ce8796. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
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.
Ln 11 Opportunity Evaluator loads about 3k tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 1,502 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 found no risky patterns in SKILL.md.
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.

.claude/skills/ln-11-opportunity-evaluator/SKILL.md (or your agent's skills folder).Goal: Evaluate product opportunities before implementation commitment. Start from observable demand and a reachable acquisition path, eliminate weak candidates early, and recommend one low-cost validation step without manufacturing market precision.
Execution contract: The checklist defines completion. Track each item internally as PENDING, PROVEN with evidence, CLEARED with evidence its condition is absent, or UNPROVEN with a gap; reading, delegation, tool failure, a zero exit status, or a self-reported success is not proof; only the observed outcome is. Reconcile after each section. Before returning, resolve all PENDING, count only PROVEN and CLEARED, and apply verdict and approval rules to every gap.
Preserve intent, scope, and existing authorization. Continue authorized work; ask only for consequential unresolved choices or required external approval. When no one can answer during the run, state the exact question and apply the skill's verdict for the remaining gap instead of waiting or guessing. Scale depth to material risk without skipping checks. Preserve dependency and safety order; otherwise choose an appropriate verification method.
Accept equivalent user or repository evidence; no other skill, named artifact, or complete lifecycle is required. Preserve source requirement and decision IDs. Bind reused evidence to relevant source versions, dirty changes, configuration, and environment; invalidate only affected claims.
On continuation, reconcile task, authorization, current state, and unresolved evidence. For long work, return a compact continuation record or update an already authorized artifact; read-only skills do not persist it. Distinguish artifact readiness, verified behavior, and external-action authority.
Prepare authorized work before required approval. If blocked by an instruction, cite its exact source and unresolved boundary; do not invent approval gates from caution.
| Need | Preferred tool | Use it when | Fallback |
|---|---|---|---|
| Product and constraints | User context plus existing product, analytics, customer, and strategy documents | Establishing audience, assets, channels, economics, and non-goals | State assumptions and request only consequential missing intent |
| Current demand and acquisition | Web research, trend or marketplace data, communities, reviews, ads, directories, and primary customer evidence | Every external market claim that affects elimination or recommendation | Mark the signal unavailable; never infer a number from search-result count |
| Competition and pricing | Competitor product pages, pricing, release history, distribution channels, reviews, and public filings where relevant | Establishing substitutes, willingness-to-pay signals, and credible differentiation | Use qualitative evidence with explicit confidence |
| Feasibility and validation cost | Existing capabilities, public APIs, regulations, platform rules, and current official documentation | Comparing the cheapest credible experiment and major blockers | Label estimates and name the evidence still required |
Keep the evaluation read-only. Do not create project files, roadmaps, Epics, Stories, implementation plans, campaigns, listings, advertisements, or customer outreach.
| Class | Meaning |
|---|---|
MEASURED | Direct analytics, transactions, experiments, or instrumented observations with known method and date |
REPORTED | A primary source reports a value or behavior, but the underlying measurement is not independently available |
ESTIMATED | A stated model based on explicit inputs and assumptions |
INFERRED | A qualitative conclusion from observable proxies |
UNKNOWN | Evidence is unavailable, stale, incomparable, or too weak to support a decision |
Do not turn REPORTED, ESTIMATED, or INFERRED evidence into a measured market size, search volume, conversion rate, revenue, or willingness-to-pay claim. Date every external source and distinguish the event date from the publication date when they differ.
Treat the creator thesis, intended experience, taste, and conviction as owner preferences and strategic-fit inputs, never as demand, acquisition, or willingness-to-pay evidence.
UNKNOWN under the rule below.UNKNOWN rather than labeling them invalid when a cheap primary experiment can resolve the uncertainty.INCONCLUSIVE.RECOMMEND <candidate> only when the candidate has a credible demand signal, reachable channel, differentiating path, plausible value exchange, and executable validation experiment.INCONCLUSIVE when candidates remain plausible but evidence cannot select among them or a cheap experiment is required; use DO_NOT_PURSUE only when evidence eliminates every candidate within scope.BLOCKED when the decision lacks product context, candidate scope, lawful research access, or a safe validation boundary.Report in the user's language, in this order; label all five fields and state each fact once. Use controlled plain language: one fact per sentence, usually under 20 words, active voice, and one term per concept, with no synonyms for verdicts, IDs, or states. Small results may use one line per field; omit empty tables and do not copy linked artifacts:
Checklist: X/Y complete; Incomplete: None or each UNPROVEN item's reason, outcome impact, and exact next action; residual risks and required decisions.Skill-specific evidence: Product, audience, candidates, constraints, and creator thesis separated from market evidence. Compare demand, channel, substitutes/wedge, economics, validation cost, source/date/class, and confidence. For eliminated or deferred candidates give decisive evidence or unknown and falsification/resolution condition. State the recommendation or inconclusive rationale and the proposed experiment contract, budget, stop rule, and decision-changing evidence; do not execute outreach or experiments.

SKILL.md names no scripts, command-line tools or credentials: Ln 11 Opportunity Evaluator is instructions for the agent only.
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 no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Ln 11 Opportunity Evaluator is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 3k tokens (SKILL.md is roughly 12k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
