Competitors Analysis

Competitors Analysis

Build competitor intelligence that can be shared, re-run, and audited later. This skill has two layers:

1. Repository evidence: clone or update the competitor code under the durable competitors workspace, then cite facts from actual files and commits.
2. Landscape synthesis: summarize positioning, pricing, strengths, weaknesses, gaps, and opportunities, but only after separating sourced facts from judgment.

This skill intentionally subsumes lightweight "competitor scan" workflows. A scan is useful for the landscape table, but it is not enough for technical conclusions.

Entry Router

If the user's request is missing the product/market or target customer segment, ask for that context before synthesizing positioning or opportunity claims. Known competitors are optional; if absent, use Discover mode.

Use the user's wording to choose the path:

Durable Source Layout

Use a durable workspace, not /tmp. The default base is:

bashCopy code
COMPETITORS_BASE="${COMPETITORS_BASE:-$HOME/workspace/competitors}"

Directory convention:

textCopy code
$COMPETITORS_BASE/
└── {product-slug}/
    ├── {owner-repo}/
    └── ...

Use owner-repo for GitHub repositories so forks and similarly named projects do not collide. If the user's machine already has a product directory, use it as the source of truth and do not re-clone elsewhere.

Preflight

Before analysis, establish these facts from commands, not memory:

bashCopy code
repo="$COMPETITORS_BASE/{product-slug}/{owner-repo}"
test -d "$repo/.git"
git -C "$repo" remote -v
git -C "$repo" fetch --all --prune
git -C "$repo" log -1 --format='%H%x09%cI%x09%s'

If the repository is missing, clone it first. Prefer SSH for GitHub when possible:

bashCopy code
mkdir -p "$COMPETITORS_BASE/{product-slug}"
git clone --depth 1 <git-ssh-url> "$COMPETITORS_BASE/{product-slug}/{owner-repo}"

If SSH fails for a public repository, report the failure and retry with the repository's HTTPS URL only when that keeps the work moving.

Discovery Workflow

Use gh search repos for GitHub repository discovery. Search multiple query phrases; do not trust one keyword.

bashCopy code
gh search repos "product keywords" \
  --limit 30 \
  --archived=false \
  --json fullName,url,description,stargazersCount,forksCount,openIssuesCount,language,pushedAt,updatedAt,defaultBranch

For each candidate, record:

Clone only candidates that are relevant to the user's product or analysis goal. For broad markets, first present a shortlist with evidence and then analyze the strongest set.

Repository Fact Gathering

Read files in this order and capture exact sources:

1. Project metadata: package.json, pyproject.toml, Cargo.toml, go.mod, or equivalent.
2. README and docs: positioning, screenshots, installation, pricing links.
3. Entry points: main, bin, scripts, src/, app/, packages/.
4. Core implementation: renderer, parser, storage, export, sync, auth, API, or domain-specific modules.
5. Tests and fixtures: they often reveal supported data structures and edge cases.
6. Releases/changelog: current direction and recent changes.

Use nl -ba <file> or an editor with line numbers before citing. Every technical claim about implementation needs file:line evidence.

Report Structure

For a single competitor, use references/profile_template.md.

For a landscape summary, use this structure:

markdownCopy code
# {Product} Competitor Landscape

## Source Register
| Competitor | Local path | Remote | Commit | Retrieved |
|---|---|---|---|---|

## Positioning
| Competitor | User segment | Primary promise | Source |
|---|---|---|---|

## Product And Technical Comparison
| Dimension | Competitor A | Source | Competitor B | Source | Our product | Source |
|---|---|---|---|---|---|---|

## Strengths
| Competitor | Strength | Evidence | Why it matters |
|---|---|---|---|

## Weaknesses And Gaps
| Competitor | Gap | Evidence | Opportunity |
|---|---|---|---|

## Opportunities
| Opportunity | Evidence base | Product implication | Confidence |
|---|---|---|---|

## Risks And Assumptions
| Item | What is known | What still needs verification | Next check |
|---|---|---|---|

Evidence Rules

Required

Forbidden

Do not write unsupported technical claims. Avoid these patterns unless they appear inside an explicit "bad example" block:

When evidence is unavailable, write 待验证 and state the exact next check that would verify it.

Output Quality Bar

Before finishing, run the checks in references/analysis_checklist.md:

• Local repository exists under $COMPETITORS_BASE/{product-slug}/.
• Remote URL and latest commit are recorded.
• Each technical claim has a file:line citation.
• Market facts have a source and retrieval date.
• Landscape judgments are separated from facts.
• The final answer names gaps, opportunities, and risks without pretending they are code facts.

Script

Use scripts/update-competitors.sh as the starting point for durable competitor repository management:

bashCopy code
COMPETITORS_BASE="$HOME/workspace/competitors" \
PRODUCT_NAME="{product-slug}" \
./scripts/update-competitors.sh status

./scripts/update-competitors.sh discover "claude code viewer"
./scripts/update-competitors.sh clone-url https://github.com/org/repo
./scripts/update-competitors.sh pull

The script is a template. For a long-running product, copy it into that product's own repo or operations directory and fill the persistent competitor list.

Relationship To Product Analysis

product-analysis may invoke this skill for compare mode. Keep this skill focused on competitor discovery, repository evidence, and competitive synthesis. Do not turn it into a general product audit orchestrator.
