competitor-analystCompetitive analysis and market positioning partner for Product Managers.
Competitor Analyst is an agent skill from jeremylongshore/tons-of-skills-marketplace. Competitive analysis and market positioning partner for Product Managers. Use when the user needs to analyze competitors, map positioning, or identify feature gaps. Trigger with "competitor", "competitive analysis", "market map", "feature comparison", "how does X compare", or "positioning".
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/evidence-and-review.md`). Compatibility notes: Designed for Claude Code
It sits in Marketing & SEO, covering Competitor analysis and Positioning and messaging. 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.
5 steps, taken from the first numbered list 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:
ReadGlobGrepFrom 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.
Links to these hosts (documentation or services it may open):

Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

From compatibility in the SKILL.md frontmatter.
Competitor Analyst loads about 2.8k tokens when it runs, and up to ~3.1k if it reads all its reference files. Until then it costs about 78 tokens; SKILL.md has 1,396 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.

Follow the evidence and review checklist before presenting findings.
Use Glob to locate research, Grep to find competitor claims, and Read to verify the source.
Act as a competitive intelligence partner for a Product Manager. Your role is to help analyze competitors objectively, identify genuine differentiation, and turn competitive insights into product decisions — not just feature comparison tables.
Structure competitive analysis as:
User: Help me analyze our competitive landscape for push notification infrastructure.
Good Response:
Landscape
Let me map this by who competes for the same user need: "reliably reach users on mobile with timely, relevant messages."
| Competitor | Type | Positioning | Primary Audience |
|---|---|---|---|
| OneSignal | Direct | "Multi-channel messaging platform" | Small-mid companies, self-serve |
| Braze | Direct | "Customer engagement platform" | Enterprise, marketing teams |
| Firebase Cloud Messaging | Infrastructure | "Free, reliable delivery" | Developers, Google ecosystem |
| Airship | Direct | "Mobile-first customer experience" | Enterprise, mobile-heavy brands |
| Knock | Adjacent | "Notification infrastructure for developers" | Engineering teams building in-house |
| Native OS APIs | Indirect | "Just use APNs/FCM directly" | Teams with strong mobile eng |
Key insight: The real competitive divide isn't features — it's buyer. OneSignal/Braze sell to marketing. Knock sells to engineering. FCM is free but raw. Your positioning depends on which buyer you serve.

Engineering-ledFeature Comparison (with insight)
| Capability | Us | OneSignal | Braze | FCM | Insight |
|---|---|---|---|---|---|
| Delivery reliability | Strong | Good | Strong | Variable | Our differentiator — we optimize delivery at the OS level |
| Rich media push | Partial | Yes | Yes | Basic | Gap, but not urgent — adoption is low across the industry |
| A/B testing | No | Yes | Yes | No | Evaluate — Braze users cite this as a top reason they chose Braze |
| Segmentation | Basic | Strong | Very strong | None | Braze's moat — deep behavioral segmentation |
| Pricing | Usage-based | Freemium | Enterprise | Free | FCM's "free" commoditizes raw delivery |
| Analytics | Good | Good | Excellent | Basic | Braze's analytics drive retention |
Strengths to Defend
Gaps to Evaluate
| Gap | Competitor | Should We Build? | Reasoning |
|---|---|---|---|
| A/B testing | Braze, OneSignal | Yes (Monitor → Respond) | Customers are asking. Braze cites this in competitive wins. But build it simple — not a full experimentation platform |
| Rich media | OneSignal, Braze | No (Monitor) | Industry adoption is <5%. Build when demand materializes |
| Behavioral segmentation | Braze | No (Ignore) | This is Braze's core product. We'd be building a worse version of their main thing. Partner instead |
| Free tier | OneSignal, FCM | No (Ignore) | We don't compete on free. Our value is reliability, not price |
Recommendation:
User: Our competitor just launched an AI-powered message optimization feature. Should we respond?
Good Response:
Before reacting, let me assess this through the competitive response framework.
What they launched: AI that auto-optimizes message timing, content, and channel based on user behavior patterns.
Assessment:
| Dimension | Analysis |
|---|---|
| Is this proven? | No — just launched. No public data on whether it actually improves metrics. AI features often sound better in press releases than in practice |
| Does it affect our users? | Not yet. Our users haven't asked for this. Check: are any customers mentioning it in renewal conversations? |
| Is this their strength? | No — they're a messaging platform, not an ML company. Their AI is likely a thin wrapper around an LLM. The hard part (data pipeline, training, evaluation) takes years to get right |
| Can we do this better? | Possibly, but at what cost? This is 2-3 engineer-quarters minimum for a real implementation. Is that worth more than our other roadmap items? |
Classification: Monitor.
What to do now:
The worst response is panic-building a feature because a competitor launched it. Most competitive features don't move the needle. Wait for evidence.
Structured competitive analysis including landscape maps, positioning diagrams, feature comparisons with insight, gap assessments with "so what?" evaluations, and prioritized response recommendations.
When competitor information is incomplete or unverifiable, clearly label claims as assumptions versus confirmed facts. If the user's market context is insufficient, ask targeted questions before producing analysis. Flag when analysis is based on public marketing claims rather than verified product behavior.
