Parse Reply

Parse Reply is a skill for Claude Code, Codex from YuiZhou/dayarc-agent. It costs 13 tokens per session (2,748 once invoked), scanned A, original, MIT.

A parser that extracts corrections from a reply to a brief email. It removes HTML formatting, quoted original messages, and email signatures before interpreting the reply.

In plain words
What is it for?
Use it to process plain-text or HTML email replies and identify the corrections they contain.
Why use it?
It prevents the quoted email and signature from being mistaken for new instructions or corrections. It leaves only the user's actual response to analyze.

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

Parse Reply 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 4d 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 — 254 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Input

Text of the user's reply to a brief email.

Pre-processing

1. Strip HTML (if input is HTML)

If the input contains HTML tags, extract plain text before doing anything else:

  • Remove all HTML tags (e.g. <div>, <p>, <br>, <span>, <b>, <blockquote>, etc.)
  • Decode HTML entities (&nbsp; → space, &amp;&, &lt;<, &gt;>, &quot;")
  • Collapse multiple consecutive blank lines into a single blank line
  • Strip leading/trailing whitespace from each line

2. Strip quoted original email

After HTML stripping (or if input was already plain text), remove everything below the first occurrence of any of these separator patterns:

  • A line starting with From:
  • A line starting with Sent:
  • A line that is exactly --- or ___ or ***
  • A line starting with > followed by On ... wrote:
  • A line starting with ________________________________ (Outlook's horizontal rule in plain-text format)
  • A line matching On .{5,80} wrote: (Outlook's "On Mon 24 Mar, Dayarc <...> wrote:" pattern)

Only parse the text above the first separator.

3. Strip email signatures

After removing quoted text, also discard lines from the first occurrence of a signature block marker:

  • A line that is exactly -- (standard signature delimiter)
  • A line containing only Sent from my iPhone / Sent from my Android / Get Outlook for iOS (and similar auto-appended footers)

Only parse the text above the first signature marker.

Output (JSON)

{
  "corrections": [{
    "action": "mark_done",
    "target": "auth migration",
    "detail": "User says auth migration is complete"
  }],
  "quality_signals": [{
    "sentiment": "negative",
    "detail": "too much noise in inbox section"
  }]
}

Instructions

The user may write in any free-form style — there are no required keywords or formats. Read each sentence for intent and extract meaning, even when phrasing is indirect or implicit.

  1. Parse natural language corrections. Infer the action from context — do not require specific trigger words:
    • mark_done: any sentence conveying that something was completed, sent, fixed, resolved, or handled. Examples of intent (not exhaustive): "X is done", "finished X", "I already fixed the issue related to X", "I already sent the mail to my peer about X", "that's shipped", "merged", "resolved the X problem".
    • remove: any sentence conveying that something is no longer relevant, was cancelled, doesn't need tracking, or should be dropped. Examples: "drop X", "X got cancelled", "no longer relevant", "ignore X", "we decided not to do X".
    • add_priority: any sentence conveying a new thing to track, do, or remember. Examples: "remind me to X", "I need to X", "add X as priority", "don't forget X", "new priority: X", "I should chat with PM".
    • correct: any sentence conveying that existing information is wrong or needs updating. Examples: "actually X is ...", "correction: ...", "X should be Y not Z".
    • For indirect references (e.g. "I already fixed the issue related to the UI"): extract the most specific identifiable subject as target (e.g. "UI issue") and note the indirect phrasing in detail.
  2. Parse quality signals — sentences that evaluate the brief itself (not specific work items). Classify sentiment and extract detail:
    • positive: any expression of approval, usefulness, or accuracy about the brief. Examples: "great brief", "spot on", "exactly right", "really useful", "perfect", "loved the summary".
    • negative: any expression that the brief was noisy, inaccurate, incomplete, or off-focus. Examples: "too much noise", "priorities were off", "missed my X work", "not relevant", "wrong focus", "too long", "cluttered".
    • Map each match to { sentiment: "positive"|"negative", detail: "<normalized phrase or quoted fragment>" }.
  3. Ignore purely social/phatic replies with no work content: "thanks", "looks good", "ok", "got it", "👍". These produce neither a correction nor a quality signal.
  4. A reply may contain both corrections and quality signals — extract all.
  5. If no actionable content found, return empty arrays for both corrections and quality_signals.

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.
