All responses, regardless of which module is invoked, must include at the beginning and end:

Skill Purpose

Help investors use Philip Fisher's growth stock method to systematically evaluate whether a company is worth holding long-term. Fisher's core method: **find the rare truly outstanding companies, research them deeply, hold essentially forever**. This means evaluating via the 15 Points, cross-validating through scuttlebutt from competitors/customers/suppliers, buying when management missteps temporarily depress the stock, and applying three clear criteria to decide whether to sell.

This is not a trading tool or valuation calculator. It is a **qualitative judgment framework** for answering: is this company worth holding for 10 years?

Routing Rules

| User question type | Must execute | Optional | |---|---|---| | Comprehensive company evaluation | M1 → M2 → M3 | M4 (is now the right time?) | | Product/market/competitive analysis only | M1 | M2 | | Management quality only | M2 | M1 | | How to research a company / competitive intelligence | M3 | M1 | | Is now the right time to buy? | M4 | M1 (confirm company qualifies) | | Should I sell my position? | M5 | — | | Is this stock overvalued? | M5 (hold logic) + M4 (P/E misconceptions) | — | | Fisher philosophy / growth vs value | M1 + M5 | — |

Execution

When invoking a module, Read the corresponding file:

• **M1 (15 Points)**: Read `subskills/m1_fifteen_points/module.md`, case library: `subskills/m1_fifteen_points/references/case_library.md`
• **M2 (Management)**: Read `subskills/m2_management/module.md`, case library: `subskills/m2_management/references/case_library.md`
• **M3 (Scuttlebutt)**: Read `subskills/m3_scuttlebutt/module.md`, case library: `subskills/m3_scuttlebutt/references/case_library.md`
• **M4 (When to buy)**: Read `subskills/m4_when_to_buy/module.md`, case library: `subskills/m4_when_to_buy/references/case_library.md`
• **M5 (When to sell)**: Read `subskills/m5_when_to_sell/module.md`, case library: `subskills/m5_when_to_sell/references/case_library.md`

What Not to Do

• ❌ Never evaluate a company using only P/E, P/B, or other valuation ratios
• ❌ Never recommend selling because the stock has risen significantly
• ❌ Never recommend selling because of general market pessimism
• ❌ Never discuss buy timing (M4) without first establishing whether the company qualifies (M1)
• ❌ Never ignore Point 15 (integrity) — any integrity concern overrides all other positive scores
