reddapi

reddapi is a skill for Claude Code from lignertys/reddit-research-skills. It costs 143 tokens per session (3,636 once invoked), scanned B, original, MIT.

A skill for searching Reddit through reddapi.dev, a third-party index of Reddit discussions rather than Reddit's official API. It supports meaning-based search, trend checks, and finding relevant subreddits without Reddit app registration.

In plain words
What is it for?
Use it to search discussions by topic, examine trends over time, and discover subreddits related to a subject.
Why use it?
It avoids the setup required for Reddit OAuth, which is the permission process used by applications to access Reddit's official API.

SkillSpector: 7 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Prompt Injection · line 75
    This pattern attempts to override system instructions or ignore safety constraints. Without LLM analysis, manual review is recommended.
    Fix: Remove or rewrite any text that instructs the agent to ignore prompts, override safety rules, or trust unverified content. Ensure skill content cannot be injected to alter agent behavior.
  • high YARA Match · line 75
    YARA rule matched a hack tool or exploit indicator (offensive tools, reconnaissance, privilege escalation, or exploit frameworks).
    Fix: Remove offensive tool references and exploit code. Legitimate agent skills should not contain penetration testing tools, exploit frameworks, or reconnaissance utilities.
  • high Supply Chain · line 169
    Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.
    Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.
  • medium Excessive Agency · line 52
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
  • medium Data Exfiltration · line 93
    Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
    Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

reddapi scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Instruction-override phrasingmediumPrompt injection

Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.

phrased as one ("ignore previous instructions", a fake system prompt,

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

About This Skill

This was the first skill published for reddapi.dev. It has since grown into reddit-research, which covers the same endpoints below plus market-research query playbooks and a fuller pitch on why semantic search beats keyword search on Reddit. This file stays live and fully functional under its original name so existing installs keep working - if you're installing fresh, prefer reddit-research.

Overview

Search Reddit's archive through reddapi.dev, a third-party indexer (not the official Reddit API - no OAuth, no app registration). Two search modes, a trends endpoint over a date range, and subreddit lookup.

All endpoints require the auth header built in "Credentials" below. All POST requests must also send Content-Type: application/json - omitting it returns HTTP 403 "Cross-site POST form submissions are forbidden".

Credentials

REDDAPI_API_KEY lives in the environment of the shell that runs the request. Its value is never needed in this conversation.

The operator sets both variables once, in their own shell, before the agent runs anything. The agent never reads, writes, or transports the key's value:

export REDDAPI_API_KEY=...                                  # from https://reddapi.dev/account
export REDDAPI_AUTH="Authorization: Bearer $REDDAPI_API_KEY"

Every request below sends -H "$REDDAPI_AUTH". No command in this skill names the key's value, and no example needs it substituted in.

  • Reference the key only as $REDDAPI_API_KEY. Never substitute the literal value into a command, a file, a code block, or a reply.
  • Never ask the user to paste, type, or send the key in chat. If they send it anyway, don't repeat it back, don't store it in a file, and suggest they rotate it at https://reddapi.dev/account.
  • Never echo, print, log, or display the key or any part of it, and never write it into a script, note, or commit.
  • If $REDDAPI_AUTH is not set, stop and say so. Do not ask the user for the key, do not offer to set it for them, and do not accept the value if it is pasted anyway - point at the two export lines above and let the user run them in their own shell, then retry.
  • On a failed request, report the HTTP status and response body only - never the request headers.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

reddapi is a skill published in the GitHub repository lignertys/reddit-research-skills (308 stars, last pushed 1mo ago), licensed MIT. It adds 143 tokens to every session and 3,636 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it B with 2 findings (instruction-override phrasing, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
