What it does

Spec Riffrec Feedback Analysis is an agent skill from leo-kuang-ai/spec-first. Analyze explicit Riffrec product-feedback captures, including riffrec-.zip, the Riffrec session.json + events.json + recording.webm + voice.webm bundle, or media/notes the user identifies as a Riffrec feedback capture. Also use for Riffrec setup and capture guidance. Do not trigger for generic podcasts, meetings, audio/video transcription, or unrelated capture/share requests.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 16 other files, including scripts and reference files (for example `evals/cases/generic-audio-not-triggered.yaml`, `evals/eval.yaml` and `evals/fixtures/scripts/asks-a-question.sh`).

It sits in Media & Creative, covering Customer feedback analysis, Transcription and Podcasting. The repository describes itself as: 仓库原生 AI Coding Harness —— 把一次性 AI 对话变成可治理、可验证、可沉淀的工程闭环 · spec-first.cn. The licence is MIT.

When your agent uses it

  • Riffrec setup and capture guidance
  • Generic podcasts
  • Audio/video transcription
  • Unrelated capture/share requests

Example prompts

  • “/spec-riffrec-feedback-analysis”

Requirements

  • Python 3
  • A Bash shell
  • A credential in OPENAI_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 74655dc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    Ships 2 files in scripts/ (Shell and Python), which the agent can run.

    Shell commands in SKILL.md call:

    • bash

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • OPENAI_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Spec Riffrec Feedback Analysis loads about 1.4k tokens when it runs, and up to ~6.1k if it reads all its reference files. Until then it costs about 105 tokens; SKILL.md has 585 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~105
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~6.1k

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.

Safety

Auto-check passed

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); the scripts in this folder are not scanned.

description
Analyze explicit Riffrec product-feedback captures, including `riffrec-*.zip`, the Riffrec `session.json` + `events.json` + `recording.webm` + `voice.webm` bundle, or media/notes the user identifies as a Riffrec feedback capture. Also use for Riffrec setup and capture guidance. Do not trigger for generic podcasts, meetings, audio/video transcription, or unrelated capture/share requests.

Riffrec Feedback Analysis

Turn raw product feedback into structured evidence for downstream agents. This skill is the consumption side of Riffrec, a capture tool that records synchronized screen + voice + event sessions and emits a riffrec-*.zip bundle.

Choose the path

Route to the matching reference based on the input. Read only that reference; do not load the others.

  • Setup — user has no recording yet and asks how to install Riffrec, capture a session, or share feedback. Read references/install-riffrec.md.
  • Quick bug report — input is a short recording (under ~60 seconds), the user describes a single specific issue, or asks for "quick", "small", or "just transcribe". Read references/quick-bug-report.md. Emit one concise bug report; skip the full artifact set and brainstorm handoff. Discovering broader scope returns an escalation handoff and never authorizes a durable extensive rerun.
  • Extensive analysis — input is a longer recording, contains multiple issues / requirements / workflow walkthroughs, or the user wants requirements or brainstorm material. Read references/extensive-analysis.md. Produce a ready-to-brainstorm handoff; invoke spec-brainstorm only when the original request or a new confirmation authorizes that public workflow.

When the input is ambiguous (e.g., a zip arrived without context), inspect the recording length and event count before choosing. If still unclear, ask the user which path applies before running anything heavy.

Common rules

  • Keep raw recordings, audio chunks, zip contents, session dumps, and extracted screenshots local-only by default. Do not commit raw/ or frames/ directories unless the user explicitly asks and privacy is acceptable.
  • Text/metadata artifacts (requirements kickoff material, analysis summaries, problem analyses, source manifests) may be committed when they are needed for traceability and contain no sensitive data.
  • Use repo-relative screenshot paths in any committed doc so later agents can open the evidence without absolute local paths.

Media transcription is a separate third-party egress. Before analyzer execution, record transcription_egress_authorization: authorized | missing. It is authorized only when the current user or visible upstream handoff explicitly requests third-party transcription for this recording; analysis intent, a local file, an ambient OPENAI_API_KEY, or worker dispatch authority does not grant it. Pass --transcribe only when authorized. Otherwise pass --no-transcribe, preserve local frames/events/notes analysis, and report the missing transcript limitation. The analyzer returns the authorization source, provider identity, and whether a provider request was sent.

Dispatch Authorization Boundary

在把 recording evidence、transcript、screenshots 或 source-mapping context 交给任何 worker 前,记录:

yaml
worker_dispatch_authorization: authorized | missing
capability_probe: not_applicable | attempted | unavailable
worker_dispatch_capability: available | missing | unknown
worker_context_isolation: isolated | inherited | unknown
worker_model_override: supported | unsupported | unknown
worker_bounded_parallelism: supported | unsupported | unknown

workflow invocation does not authorize dispatch。只有当前用户或可见 upstream handoff 明确请求 subagent、delegated work、persona 或 parallel work 时才可派发;输入文件、分析规模、工具权限或本 Skill 被调用都不构成授权。缺授权时不得探测 tool schema,固定为 capability_probe: not_applicable + worker_dispatch_capability: unknown,inline 或 serial 执行并记录 dispatch_authorization_missing。只有授权后才把 current-session registry/schema 作为 provider_untrusted evidence 检查:确认缺失时记录 subagent_capability_missing;surface 不可用、schema 不完整或候选不唯一时记录 worker_capability_unproven,均 inline 或 serial。隔离、模型覆盖和有界并发只取 live facts;required isolation 未满足时保持依赖 gate 打开,model unknown 时继承,parallelism unknown 时串行。记录 worker_dispatch_outcome。任何派发还必须遵守 local-only/privacy 边界,只发送完成 bounded unit 所需的最小证据。Inline fallback 不得声称 independent analyst coverage。

Analyzer entrypoint

All non-setup paths share the same analyzer, which ships in this skill's scripts/ directory. The Bash tool's working directory is the user's project, not the skill directory, so a bare scripts/<name> path will not resolve. Invoke it by the skill's own absolute path: set SKILL_DIR to the directory you loaded this spec-riffrec-feedback-analysis SKILL.md from, in the same command (shell state does not persist between Bash calls):

bash
SKILL_DIR="<absolute path of the directory containing this SKILL.md>"
bash "$SKILL_DIR/scripts/run-python.sh" "$SKILL_DIR/scripts/analyze_riffrec_zip.py" /path/to/input --no-transcribe

Accepted inputs: a Riffrec .zip, an .mp4 / .mov / .webm video, an .m4a / .mp3 / .wav audio file, or a meeting-notes .md. Use --output-dir <dir> to control where artifacts land. In repos with docs/brainstorms/, the default remains docs/brainstorms/riffrec-feedback/ as a documented evidence/kickoff-artifact exception; it is not the durable spec-brainstorm output convention. The quick path overrides the output dir to a temp location so nothing pollutes the repo.

The Spec-First output format used by the extensive path is documented in references/spec-first-feedback-format.md.
