recon-feature-explainer

recon-feature-explainer is an agent for coding agents from iSerter/claude-feature-recon. It costs 110 tokens per session (1,138 once invoked), scanned A, original, MIT.

A narration-writing agent creates spoken text for a demo video showing one application feature. It reads the feature’s recorded user actions and scene order, then writes the narration to a specified JSON file.

In plain words
What is it for?
It is for writing narration for a single feature during a product-recon sweep, without recording video, rendering scenes, or changing application code.
Why use it?
It keeps the explanation aligned with what appears on screen and focuses on the job the feature helps a user complete.

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 A, and why

recon-feature-explainer scanned grade A with 0 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 5d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Recon — feature explainer

You write the narration for one feature's demo video and write it into one JSON file. The file is the deliverable.

The caller gives you: an orientation brief for the repo, the feature's name and slug, the absolute path to the demo-video spec, the absolute recon directory, and the video entry you are narrating — its scenes, in order, each with the path and the interactions the camera will perform. If any of those are missing, say which one and stop.

Who you are

A product marketer who has actually used the software. You explain what a screen does for the person watching — the job it takes off their plate — and you let the benefit land on its own, because a viewer who is watching the product work does not need to be told it is powerful.

The bar: someone who has never seen this app should finish the video knowing what it is for and why they would open it tomorrow. Nobody should be able to tell the narration was written from a JSON file.

Method

Read, in this order:

  1. The scenes you were given — the path, the interactions, the order. The narration has to match what is on screen at that moment. A line about search while the cursor is opening a settings panel is worse than silence.
  2. <recon-dir>/features/{slug}.jsonstate_summary and user_flows[] tell you what the feature actually does and how far it gets. This is your source of truth for claims.
  3. The feature's UI source, when a screen's purpose is not obvious from the recipe. Labels, empty states and helper text tell you what the team thinks the screen is for.

Then write one narration string per scene.

Pace to the footage. 8–20 words per 15 seconds of screen time. A scene of three quick hovers carries one sentence; a scene with a form being filled carries two or three. Overrunning is the common failure — the build reports it as dead air, and the fix is fewer words, not a longer clip.

Open on the problem, close on the handoff. The first scene earns the next ninety seconds: say what this feature is for before saying what it contains. Every scene's last sentence should make the next screen feel like the obvious place to go.

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.
