`proceed(): mixed` — continue to next interceptor or target handler + - `getArguments(): array` — inspect method arguments + - `replaceArgument(string $name, $value)` — modify arguments before proceeding + - `getObjectToInvokeOn()` — get the handler instance + - Must call `proceed()` or the handler chain stops + +6. **Channel interceptors** (message-level, separate from method interceptors): + - `ChannelInterceptor` interface with `preSend()`, `postSend()`, `preReceive()`, `postReceive()` + -

Logging: `#[Before]` with `LogBefore` attribute pointcut + - `#[InstantRetry(retryTimes: 3, exceptions: [...])]` — retry on specific exceptions + +8. **Testing interceptors:** + - Register interceptor class alongside handlers in `EcotoneLite::bootstrapFlowTesting()` + -

Move detailed reference material to separate files."** - -`ecotone-workflow` is at 527 lines — the only skill that exceeds the hard limit. -`ecotone-metadata` is at 491 — technically under but near the limit. - -### Problem 2: No actionable reference links -Official guideline: **"Reference supporting files from SKILL.md so Claude knows what each file contains and when to load it."** - -Current state: Most skills have a single throwaway line at the very bottom like `See references/xxx.md for more examples`. Three skills (ecotone-identifier-mapping, ecotone-laravel-setup, ecotone-symfony-setup) have **no reference links at all**. - -The problem: Claude has no guidance on **when** to load references or **what specific content** they contain. This defeats progressive disclosure — Claude either never loads them, or loads them unnecessarily. - -### Problem 3: Large inline code blocks that belong in references -Some SKILL.md files contain 15-25 full PHP code blocks with complete class definitions (constructors, methods, use statements). This inflates context usage when the skill loads. The official pattern is: SKILL.md has the essential workflow/decision guidance with compact examples; references have the complete, copy-paste-ready code. - -### NOT a Problem: No duplication detected -The earlier plan claimed content duplication between SKILL.md and references.

Parameters: `precedence`, `pointcut`, `changeHeaders` - - `#[After]` — executes after handler completes.

Parameters: `precedence`, `pointcut` - - `#[Presend]` — executes before message is sent to channel (message-level). Parameters: `precedence`, `pointcut`, `changeHeaders` - -2. **Pointcut system** (how interceptors target handlers): - - **By class/interface**: `pointcut: MyHandler::class` — targets any handler in that class - - **By attribute**: `pointcut: CommandHandler::class` — targets methods with that attribute - - **By method**: `pointcut: 'MyHandler::handleCommand'` — targets specific method - - **Logical operators**: `&&` (AND), `||` (OR), `not()` (NOT) - - **Automatic inference**: when no explicit pointcut, inferred from interceptor method parameter type-hints (attribute parameters) - - Expression classes: `PointcutAttributeExpression`, `PointcutInterfaceExpression`, `PointcutMethodExpression`, `PointcutOrExpression`, `PointcutAndExpression`, `PointcutNotExpression` -

-4. **Header modification** (`changeHeaders: true`): - - Interceptor receives `#[Headers] array $headers` parameter - - Returns modified headers array - - Framework merges returned headers into the message via `HeaderResultMessageConverter` - - Only available on `#[Before]`, `#[After]`, `#[Presend]` (not `#[Around]`) - -5. **MethodInvocation** (for `#[Around]`): - - `proceed(): mixed` — continue to next interceptor or target handler - - `getArguments(): array` — inspect method arguments - - `replaceArgument(string $name, $value)` — modify arguments before proceeding - - `getObjectToInvokeOn()` — get the handler instance - - Must call `proceed()` or the handler chain stops - -6. **Channel interceptors** (message-level, separate from method interceptors): - - `ChannelInterceptor` interface with `preSend()`, `postSend()`, `preReceive()`, `postReceive()` - - Applied at message channel level, not handler level - - Broader scope than method interceptors - -7. **Real-world examples:** - - Transaction interceptor: `#[Around]` wrapping handler in begin/commit/rollback - - Logging: `#[Before]` with `LogBefore` attribute pointcut - - `#[InstantRetry(retryTimes: 3, exceptions: [...])]` — retry on specific exceptions - -8. **Testing interceptors:** - - Register interceptor class alongside handlers in `EcotoneLite::bootstrapFlowTesting()` - - Pass interceptor instance for DI - - Use call stack tracking to verify execution order -
