What it does

Peg Valuation is an agent skill from agentii-ai/agentii-investment-intelligence. PEG valuation, Price Earnings to Growth ratio, Peter Lynch PEG methodology, growth-adjusted valuation, earnings growth rate, PE ratio valuation, PEG sector comparison, undervalued growth stocks, fair value PEG

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/methodology.md`, `references/modes.md` and `references/output-structure.md`).

It sits in Business, Finance & HR, covering Financial modeling. The repository describes itself as: Claude-type skills for institutional equity research — 25 AI agent skills with SEC filings, XBRL financials, earnings calendars, DCF/comps/LBO models, and PPT generation. Powered… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Financial modeling

Example prompts

  • “/peg-valuation”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Executive Summary — headline conclusions (≤200 words).
  2. Core analysis sections — per this skill's methodology and analyst modes.
  3. Data classification — tag findings [FACT] / [DEDUCTED] / [VIEW] per contracts/snapshot-synthesis.md.
  4. Coverage Gaps & Citations — inline /v/ citations are PRIMARY (immediately after each fact); the bottom Citations section is a…
  5. Output frontmatter — emit the FR-090 structured block per contracts/output-frontmatter-schema.md.

What it can do on your machine

Read from SKILL.md and the folder at commit 86980e1. 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

    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.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • agentii.ai

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

  • Credentials

    Names no API keys, tokens, secrets or passwords.

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

Context cost

Peg Valuation loads about 1.6k tokens when it runs, and up to ~2.6k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 658 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.6k

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); files beside SKILL.md are not scanned.

PEG Valuation

Peter Lynch PEG (Price/Earnings to Growth) methodology. PEG = P/E Ratio ÷ Earnings Growth Rate (%). Growth-adjusted valuation that answers: "Is this stock's growth justifying its multiple?"

Preflight

Run canonical pre-flight per contracts/preflight.md.

**get_realtime_quote availability **: If get_realtime_quote is not yet deployed, prompt user for current stock price. PE numerator from search_earnings_calendar (NTM consensus EPS × current price = PE) as fallback.

Include the X-Agentii-Trace header on every tool call per contracts/x-agentii-trace-header.md — carry the _run_id from your first tool result and name yourself (and your parent, if you were spawned).

Triggers

  • PEG valuation for {ticker}
  • compute PEG ratio {ticker}
  • Peter Lynch PEG {ticker}
  • growth-adjusted valuation {ticker}
  • is {ticker} undervalued by PEG
  • PEG analysis {ticker}
  • price earnings growth {ticker}
  • compare PEG across peers
  • {ticker} PEG vs sector
  • growth at reasonable price {ticker}

Defaults

ParameterDefaultNotes
growth_sourceconsensusconsensus estimates preferred; fallback to historical CAGR
include_peerstrueSector PEG comparison
lookback_years3Historical CAGR computation window

Methodology

Retrieval Scope

structured_only — PEG uses XBRL earnings data + real-time price + earnings calendar for growth estimates.

Retrieval Strategy

See contracts/retrieval.md for the canonical decision tree; skill-specific retrieval detail is in references/methodology.md.

Temporal Scope

Default: 4 fiscal quarters (max 12). PEG uses trailing 4 quarters for LTM P/E; up to 12 for historical EPS CAGR if consensus unavailable.

Tool Allowlist

See frontmatter allowed_tools — 4 tools. get_realtime_quote for current price + PE (TTM). search_earnings_calendar for consensus EPS and long-term growth estimates. search_xbrl_facts for historical EPS to compute CAGR. search_companies for peer identification.

Protocol

Step-by-step execution detail is in references/methodology.md.

PEG Interpretation (Peter Lynch Framework)
PEG RangeRatingInvestment Implication
< 0.5Deeply UndervaluedGrowth vastly exceeds valuation; investigate for hidden risks
0.5 – 1.0UndervaluedClassic Lynch buy zone; growth justifies the multiple
1.0 – 1.5Fairly ValuedGrowth and valuation in equilibrium
1.5 – 2.0PremiumMarket paying up for growth; needs above-consensus execution
> 2.0OvervaluedGrowth insufficient to justify current multiple
NegativeN/ANegative earnings — PEG not meaningful; use revenue-based metrics

Output File

Write the final deliverable to {ticker}/{YYYY-MM-DD_HHMM}_peg-valuation_{affix}.md.

Show full SKILL.md (333 more words)Show less

Output Structure

The deliverable is a structured markdown report written to the path in ## Output File. Full section-by-section template (headings, tables, and field definitions) lives in references/output-structure.md. Required elements:

  1. Executive Summary — headline conclusions (≤200 words).
  2. Core analysis sections — per this skill's methodology and analyst modes.
  3. Data classification — tag findings [FACT] / [DEDUCTED] / [VIEW] per contracts/snapshot-synthesis.md.
  4. Coverage Gaps & Citations — inline /v/ citations are PRIMARY (immediately after each fact); the bottom Citations section is a non-duplicative roll-up index.
  5. Output frontmatter — emit the FR-090 structured block per contracts/output-frontmatter-schema.md.

Citations & memory: follow contracts/citation-and-memory.md — ≥1 citation per 200 words; every material fact, table row, and metric is immediately followed by its inline clickable https://agentii.ai/v/{ticker}/{citation_id}/{N} link; a bottom Citations section provides a non-duplicative roll-up index; the closing TUI reply includes a compact Key Citations list (headline 5–10 facts) of clickable /v/ URLs; and append the run to agentii.md per contracts/agentii-md-schema.md.

Tool Fallbacks

Per-tool failure modes and fallback actions are tabulated in references/tool-fallbacks.md.

Memory & Snapshot

  • Memory load (pre-flight): load prior workspace context for the ticker before retrieval — see contracts/memory-load.md.
  • Structured output frontmatter: emit the FR-090 block (key_metrics, conclusions, facts_count, deducted_count, views_count, citation_count) per contracts/output-frontmatter-schema.md.
  • Snapshot synthesis: after writing the deliverable, update the two-tier snapshot and classify findings as [FACT]/[DEDUCTED]/[VIEW] — see contracts/snapshot-synthesis.md.
  • Session archival: record the run under sessions/{YYYY-MM-DD}/ and update sessions/INDEX.md per contracts/session-format.md.

Final Summary (TUI)

End the closing chat reply with a compact Key Citations list (headline 5–10 facts), each a clickable https://agentii.ai/v/{ticker}/{citation_id}/{N} link, so the user can cmd+click straight to the exact SEC page. See contracts/citation-and-memory.md.
