fireflies-common-errorsDiagnose Fireflies transport, GraphQL, permission, plan, processing, and operation-limit failures without unsafe retries or data probing.
Fireflies Common Errors is an agent skill from jeremylongshore/tons-of-skills-marketplace. Diagnose Fireflies transport, GraphQL, permission, plan, processing, and operation-limit failures without unsafe retries or data probing. Use when an integration fails or returns partial data. Trigger with "Fireflies error", "toomanyrequests", or "objectnotfound Fireflies".
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Designed for Claude Code; live Fireflies work requires network access
It sits in Backend & APIs, covering GraphQL. It works with GraphQL. 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.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 80f86df. 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:
ReadGlobGrepWriteEditFrom 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.
Hosts in commands or code, which the agent is likely to contact:
api.fireflies.aiFrom URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
FIREFLIES_API_KEYREDACTED_KEYFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Designed for Claude Code; live Fireflies work requires network access
From compatibility in the SKILL.md frontmatter.
Fireflies Common Errors loads about 1k tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 76 tokens; SKILL.md has 443 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.

Separate HTTP failures from top-level GraphQL errors and domain state. Normalize auth_failed, object_not_found, invalid_args or invalid_arguments, require_elevated_privilege, require_ai_credits, too_many_requests, unsupported_platform, and processing-state nulls.
For authenticated operations, inject FIREFLIES_API_KEY from an approved secret manager and send it only as Authorization: Bearer REDACTED_KEY to https://api.fireflies.ai/graphql. Never print, commit, place in a URL, forward to a browser, or include the key in evidence. Webhook signing secrets are separate credentials and must not be reused as API keys.
Use Read, Glob, and Grep to inspect code, configuration, tests, and evidence. Use Write/Edit only for approved implementation or documentation changes. Do not query Fireflies, retrieve meeting content, create an AskFred thread, upload media, change account state, replay an event, or deploy merely because this skill was invoked.
Require approval before changing roles, plans, keys, privacy, meeting access, or replaying a mutation. Preserve the failing state and present the exact proposed change before acting.
Return the exact operation or event surface, environment, authorization class, selected field groups, validation results, content-free metrics, decisions, and a concise pass/fail receipt. Keep secrets and meeting-derived content out of general output.
Before reporting success, rerun the smallest relevant deterministic check, compare actual state with the requested outcome and current contract, verify no secret or meeting-derived content entered logs or artifacts, and record unresolved uncertainty explicitly.
Read official Fireflies.ai evidence before relying on a field, filter, event, permission, plan limit, mutation, or processing state.

Diagnose Fireflies transport, GraphQL, permission, plan, processing, and operation-limit failures without unsafe retries or data probing. Fireflies Common Errors is an agent skill from jeremylongshore/tons-of-skills-marketplace. Diagnose Fireflies transport, GraphQL, permission, plan, processing, and operation-limit failures without unsafe retries or data probing.
Fireflies Common Errors fits situations like: an integration fails; returns partial data; with Fireflies error; toomanyrequests.
Run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill fireflies-common-errors -a claude-code`. Or copy the skill folder (skills/.curated/fireflies-common-errors in jeremylongshore/tons-of-skills-marketplace) into .claude/skills/fireflies-common-errors in your project. Claude Code loads it when a task matches its description.
Run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill fireflies-common-errors -a codex`. Or copy the skill folder (skills/.curated/fireflies-common-errors in jeremylongshore/tons-of-skills-marketplace) into .agents/skills/fireflies-common-errors in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill fireflies-common-errors -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/fireflies-common-errors, .gemini/skills/fireflies-common-errors, .github/skills/fireflies-common-errors and .opencode/skills/fireflies-common-errors in your project.
Going by SKILL.md and its folder, Fireflies Common Errors needs credentials named FIREFLIES_API_KEY and REDACTED_KEY. Our summary lists: A credential in FIREFLIES_API_KEY; A credential in REDACTED_KEY. Its frontmatter pre-approves these tools: Read, Glob, Grep, Write, Edit. Compatibility (from SKILL.md): Designed for Claude Code; live Fireflies work requires network access.
SKILL.md names 1 domain. In commands or code: api.fireflies.ai; the agent is likely to contact it when it follows the instructions. 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.
Fireflies Common Errors is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1k tokens (SKILL.md is roughly 4.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 431 tokens, read only when the agent opens those files.
