+# YiemAgent
+
+Julia framework for building agents with tool use.
+
+## Getting Started
+
+1. Install dependencies: `]add JSON, DataStructures, UUIDs, Dates, ...`
+2. Create a `yiemAgent` with `loadTools("src/tools")`
+3. Call `runAgent(agent, "message")` then `takeResponse(agent)`
+
+## Architecture
+
+```
+src/
+├── YiemAgent.jl          # Module entry point
+├── type.jl               # Core types (messages, tools, agent state)
+├── utils.jl              # Message formatting, validation
+├── agentCore.jl          # Agent loop, tool execution pipeline
+├── api.jl                # Public API (runAgent, takeResponse, etc.)
+└── tools/
+    ├── registry.jl       # Tool registry (loadTools, registerTool, listTools)
+    ├── getWeather.jl     # Weather lookup tool
+    ├── getTime.jl        # Time lookup tool
+    ├── writeTool.jl      # Create new tool files (self-modifying)
+    └── README.md         # Tool development guide
+```
+
+## Tool Development
+
+See `src/tools/README.md` for:
+- Tool anatomy (schema, execute, getTool)
+- Validation hooks
+- Agent loop lifecycle
+- Self-modifying tools (`writeTool`)

You will be given a previous reasoning trial in which you were given access to an Docstore API environment and a question to answer. You were unsuccessful in answering the question either because you guessed the wrong answer with Finish[<answer>], or you used up your set number of reasoning steps. In a few sentences, Diagnose a possible reason for failure and devise a new, concise, high level plan that aims to mitigate the same failure. Use complete sentences.  
-Here are some examples:
-Previous Trial:
-Question: The Rome Protocols were signed by three Prime Ministers one of which was assassinated as part of what?
-Thought 1: I need to search Rome Protocols, find the three Prime Ministers, then find what they were assassinated as part of.
-Action 1: Search[Rome Protocols]
-Observation 1: The Rome Protocols were a series of three international agreements concluded in Rome on 17 March 1934 between the governments of Austria, Hungary and Italy. They were signed by Italian Prime Minister Benito Mussolini, Austrian Chancellor Engelbert Dollfuss and Hungarian Prime Minister Gyula Gömbös. All of the protocols went into effect on 12 July 1934 and were registered in League of Nations Treaty Series on 12 December 1934.
-Thought 2: The three Prime Ministers were Benito Mussolini, Engelbert Dollfuss, and Gyula Gömbös. I need to search Benito Mussolini and find what he was assassinated as part of.
-Action 2: Search[Benito Mussolini]
-Observation 2: Benito Amilcare Andrea Mussolini (UK:  MU(U)SS-ə-LEE-nee, US:  MOOSS-, Italian: [beˈniːto aˈmilkare anˈdrɛːa mussoˈliːni]; 29 July 1883 – 28 April 1945) was an Italian politician and journalist who founded and led the National Fascist Party (PNF). He was Prime Minister of Italy from the March on Rome in 1922 until his deposition in 1943, as well as "Duce" of Italian fascism from the establishment of the Italian Fasces of Combat in 1919 until his summary execution in 1945 by Italian partisans. As dictator of Italy and principal founder of fascism, Mussolini inspired and supported the international spread of fascist movements during the inter-war period.Mussolini was originally a socialist politician and a journalist at the Avanti! newspaper. In 1912, he became a member of the National Directorate of the Italian Socialist Party (PSI), but he was expelled from the PSI for advocating military intervention in World War I, in opposition to the party's stance on neutrality. In 1914, Mussolini founded a new journal, Il Popolo d'Italia, and served in the Royal Italian Army during the war until he was wounded and discharged in 1917. Mussolini denounced the PSI, his views now centering on Italian nationalism instead of socialism, and later founded the fascist movement which came to oppose egalitarianism and class conflict, instead advocating "revolutionary nationalism" transcending class lines. On 31 October 1922, following the March on Rome (28–30 October), Mussolini was appointed prime minister by King Victor Emmanuel III, becoming the youngest individual to hold the office up to that time. After removing all political opposition through his secret police and outlawing labor strikes, Mussolini and his followers consolidated power through a series of laws that transformed the nation into a one-party dictatorship. Within five years, Mussolini had established dictatorial authority by both legal and illegal means and aspired to create a totalitarian state. In 1929, Mussolini signed the Lateran Treaty with the Holy See to establish Vatican City.
-Mussolini's foreign policy aimed to restore the ancient grandeur of the Roman Empire by expanding Italian colonial possessions and the fascist sphere of influence. In the 1920s, he ordered the Pacification of Libya, instructed the bombing of Corfu over an incident with Greece, established a protectorate over Albania, and incorporated the city of Fiume into the Italian state via agreements with Yugoslavia. In 1936, Ethiopia was conquered following the Second Italo-Ethiopian War and merged into Italian East Africa (AOI) with Eritrea and Somalia. In 1939, Italian forces annexed Albania. Between 1936 and 1939, Mussolini ordered the successful Italian military intervention in Spain in favor of Francisco Franco during the Spanish Civil War. Mussolini's Italy initially tried to avoid the outbreak of a second global war, sending troops at the Brenner Pass to delay Anschluss and taking part in the Stresa Front, the Lytton Report, the Treaty of Lausanne, the Four-Power Pact and the Munich Agreement. However, Italy then alienated itself from Britain and France by aligning with Germany and Japan. Germany invaded Poland on 1 September 1939, resulting in declarations of war by France and the UK and the start of World War II.
-On 10 June 1940, Mussolini decided to enter the war on the Axis side. Despite initial success, the subsequent Axis collapse on multiple fronts and eventual Allied invasion of Sicily made Mussolini lose the support of the population and members of the Fascist Party. As a consequence, early on 25 July 1943, the Grand Council of Fascism passed a motion of no confidence in Mussolini; later that day King Victor Emmanuel III dismissed him as head of government and had him placed in custody, appointing Pietro Badoglio to succeed him as Prime Minister. After the king agreed to an armistice with the Allies, on 12 September 1943 Mussolini was rescued from captivity in the Gran Sasso raid by German paratroopers and Waffen-SS commandos led by Major Otto-Harald Mors. Adolf Hitler, after meeting with the rescued former dictator, then put Mussolini in charge of a puppet regime in northern Italy, the Italian Social Republic (Italian: Repubblica Sociale Italiana, RSI), informally known as the Salò Republic, causing a civil war. In late April 1945, in the wake of near total defeat, Mussolini and his mistress Clara Petacci attempted to flee to Switzerland, but both were captured by Italian communist partisans and summarily executed by firing squad on 28 April 1945 near Lake Como. The bodies of Mussolini and his mistress were then taken to Milan, where they were hung upside down at a service station to publicly confirm their demise.
-Thought 3: Benito Mussolini was assassinated as part of the collapse of the Axis powers during World War II. So the Rome Protocols were signed by three Prime Ministers one of which was assassinated as part of World War II.
-Action 3: Finish[World War II]
-
-Reflection: I searched one of the prime ministers involved in the signing, then attemted to answer right away. I should have searched each of the prime ministers, then looked up 'death' on each of their pages in order to get more information before answering.

-Question: What is the elevation range for the area that the eastern sector of the Colorado orogeny extends into?
-Thought 1: I need to search Colorado orogeny, find the area that the eastern sector of the Colorado orogeny extends into, then find the elevation range of the area.
-Action 1: Search[Colorado orogeny]
-Observation 1: The Colorado orogeny was an episode of mountain building (an orogeny) in Colorado and surrounding areas. This took place from 1780 to 1650 million years ago (Mya), during the Paleoproterozoic (Statherian Period). It is recorded in the Colorado orogen, a >500-km-wide belt of oceanic arc rock that extends southward into New Mexico. The Colorado orogeny was likely part of the larger Yavapai orogeny.
-Thought 2: It does not mention the eastern sector of the Colorado orogeny. I need to look up eastern sector.
-Action 2: Lookup[eastern sector]
-Observation 2: (Result 1 / 1) The Colorado orogen, formerly called the Colorado province, is a >500-km-wide belt of oceanic arc rock (1.78\u20131.65 Ga) that extends southward into New Mexico and composes a major part of the Proterozoic provinces of southwestern United States. This transcontinental collisional event occurred during the  Paleoproterozoic (Statherian Period).[1] The Wyoming sector of the Colorado orogeny was formerly called the Medicine Bow orogeny. The eastern sector extends into the High Plains and is called the Central Plains orogeny. The boundary between the Colorado orogeny and the Wyoming craton is the Cheyenne belt, a 5-km-wide mylonitic shear zone that verges northward. The Cheyenne belt transects and cuts off the south edge of the older Trans-Hudson orogeny.[2]
-Thought 3: The eastern sector of Colorado orogeny extends into the High Plains, so High Plains is the area. I need to search High Plains and find its elevation range.
-Action 3: Search[High Plains]Observation 3: High Plains refers to one of two distinct land regions:
-Thought 4: I need to search High Plains (United States).
-Action 4: Search[High Plains (United States)]
-Observation 4: The High Plains are a subregion of the Great Plains, mainly in the Western United States, but also partly in the Midwest states of Nebraska, Kansas, and South Dakota, generally encompassing the western part of the Great Plains before the region reaches the Rocky Mountains. The High Plains are located in eastern Montana, southeastern Wyoming, southwestern South Dakota, western Nebraska, eastern Colorado, western Kansas, eastern New Mexico, western Oklahoma, and to just south of the Texas Panhandle.[4] The southern region of the Western High Plains ecology region contains the geological formation known as Llano Estacado which can be seen from a short distance or on satellite maps.[5] From east to west, the High Plains rise in elevation from around 1,800 to 7,000 ft (550 to 2,130 m).[3]
-Thought 5: High Plains rise in elevation from around 1,800 to 7,000 ft, so the answer is 1,800 to 7,000 ft.
-Action 5: Finish[1,800 to 7,000 ft]

-Observation 1: Guitars for Wounded Warriors is the sixth solo studio album by guitarist Brian Tarquin, released in August 2014 by Cleopatra Records. In 2016, it received a Best Compilation Album nomination by the Independent Music Awards. All tracks were recorded at Tarquin's Jungle Room Studios in New Paltz (village), New York. Being moved by the lack of support for returning veterans through his life Tarquin decided to compose a heavy instrumental rock album as a way to show his appreciation to all veterans. So once again he enlisted top notch players to guest with him on the album, Billy Sheehan on Black Hawk, Ron \"Bumblefoot\" Thal and Reb Beach on Taliban Terror, Steve Morse on Freedom, Chris Poland on Charlie Surfs and Hunting, Chuck Loeb on Escape Kabul, Hal Lindes on Sand & Blood, Gary Hoey on 5 Klicks To Hell and Baghdad, Alex De Rosso Dokken on Broken Arrow, and The Flyin' Ryan Brothers on Surgical Strike.  The entire album was engineered, produced and composed by Tarquin especially for each one of the guest guitarists. Partial proceeds are donated to the Fisher House Foundation from sales.
-Thought 2: Guitars for Wounded Warriors was recorded in New Paltz (village), New York. I need to search New Paltz (village), New York and find which county it is in
-Action 2: Search[New Paltz (village), New York]
-Observation 2: New Paltz is a village in Ulster County located in the U.S. state of New York. It is approximately 80 miles (130 km) north of New York City and 70 miles (110 km) south of Albany. The population was 7,324 at the 2020 census.[3]

-Action 1: Search[David Beckham's football manager]
-Observation 1: Could not find David Beckham's football manager. Similar: ['David Beckham', 'Inter Miami CF (redirect from Miami Beckham United)', 'Victoria Beckham', 'The Beckham Experiment', 'Miami Freedom Park'].
-Thought 2: I couldn't find the information on David Beckham's football manager. I need to search Manchester United and find out the timeframe of the manager.
-Action 2: Search[Manchester United]
-Observation 2: Manchester United Football Club, commonly referred to as Man United (often stylised as Man Utd), or simply United, is a professional football club based in Old Trafford, Greater Manchester, England. The club competes in the Premier League, the top division in the English football league system. Nicknamed the Red Devils, they were founded as Newton Heath LYR Football Club in 1878, but changed their name to Manchester United in 1902. After a spell playing in Clayton, Manchester, the club moved to their current stadium, Old Trafford, in 1910.. Domestically, Manchester United have won a record 20 league titles, 12 FA Cups, six League Cups and a record 21 FA Community Shields.
-Thought 3: The information about David Beckham's football manager is not available. I will search for Manchester United's managers to find the timeframe.
-Action 3: Search[Manchester United managers]
-Observation 3: Manchester United Football Club is a professional football club based in Old Trafford, Greater Manchester, England. The club was formed in Newton Heath in 1878 as Newton Heath LYR F.C., and played their first competitive match in October 1886, when they entered the First Round of the 1886–87 FA Cup. The club was renamed Manchester United F.C. in 1902, and moved to Old Trafford in 1910.. From the beginning of the club's official managerial records in 1892 to the start of the 2022–23 season, Manchester United have had 23 full-time managers.
-Thought 4: The information about David Beckham's football manager is not available. The question asks for the timeframe when the manager managed Manchester United, so I need to find a list of Manchester United managers.
-Action 4: Search[list of Manchester United managers]
-Observation 4: Manchester United Football Club is a professional football club based in Old Trafford, Greater Manchester, England.

-This trajectory is mostly incorrect as I was not able to retrieve the relevant information to answer the question. The searches are too broad and not relevant to the specific player recruited, David Beckham. The last two actions are also too similar. It would be better to first search for David Beckham and lookup information related to his manager.
-Thus the correctness score is 4

-Question: Musician and satirist Allie Goertz wrote a song about the "The Simpsons" character Milhouse, who Matt Groening named after who?
-Thought 1: The question simplifies to "The Simpsons" character Milhouse is named after who. I only need to search Milhouse and find who it is named after.
-Action 1: Search[Milhouse]
-Observation 1: Milhouse Mussolini Van Houten is a recurring character in the Fox animated television series The Simpsons voiced by Pamela Hayden and created by Matt Groening.
-Thought 2: The paragraph does not tell who Milhouse is named after, maybe I can look up "named after".
-Action 2: Lookup[named after]
-Observation 2: (Result 1 / 1) Milhouse was named after U.S. president Richard Nixon, whose middle name was Milhous. 
-Thought 3: Milhouse was named after U.S. president Richard Nixon, so the answer is Richard Nixon.
-Action 3: Finish[President Richard Nixon]
-This trajectory is correct as all of my thoughts and actions are correct. It makes sense to search for Milhouse first as it is the central subject of the question. It is also correct to directly look up the relevant information in the article, instead of trying another search. 
-Thus the correctness score is 10

-Question: Which other Mexican Formula One race car driver has held the podium besides the Force India driver born in 1990?
-Thought 1: I need to search for a list of Mexican Formula One race car drivers, then eliminate the one who drove for Force India and was born in 1990.
-Action 1: Search[Formula One drivers from Mexico]
-Observation 1: There have been six Formula One drivers from Mexico who have taken part in races since the championship began in 1950. Sergio P\u00e9rez is the most successful, having won six Grands Prix. Since 2021, P\u00e9rez drives for the Red Bull team.. P\u00e9rez is the only Mexican F1 driver to achieve a pole position. He took his first pole position at the 2022 Saudi Arabian Grand Prix, in his 219th Grand Prix meeting (a record for the most Grands Prix before a pole).
-Thought 2: Sergio P\u00e9rez, born in 1990 and drove for Force India, is not the Mexican driver we are looking for. The passage does not give me enough information about other Mexican drivers who have achieved a podium finish. I need to look up more information.
-Action 2: Lookup[Formula One drivers from Mexico]
-Observation 2: No more results.
-Thought 3: The available information doesn't allow me to determine which other Mexican Formula One race car driver, besides Sergio P\u00e9rez, has held the podium. With the search function failing to provide a full list of Mexican Formula One drivers, I need to return different search results. Let's try searching for Mexican Grand Prix winners, as they would have held the podium.
-Action 3: Search[Mexican Grand Prix winners]
-Observation 3: Could not find Mexican Grand Prix winners. Similar: ['Mexican Grand Prix', 'List of Formula One Grand Prix winners', '1990 Mexican Grand Prix', '2018 Mexican Grand Prix', '2019 Mexican Grand Prix'].
-Thought 4: Given the difficulties in finding a direct list of Mexican Grand Prix winners, I should search for the Mexican Grand Prix to get a broader picture of the race's history. This might include winners.
-Action 4: Search[Mexican Grand Prix]
-This trajectory is incorrect as my search should be related to Mexican Formula One race car drivers, not winners of the Mexican Grand Prix, a seperate event. A better search would have been for the List of Formula One Grand Prix winners, as suggested.
-Thus the correctness score is 3

+Tool that writes new Julia tool module files to disk.
+
+The agent can use this tool when it encounters a task that no existing tool
+can handle. Provide the tool's name, label, description, inputSchema, and
+execute logic as Julia code. The tool is written to `src/tools/<name>.jl`.
+
+After calling this tool, add the new file to `YiemAgent.jl` with an `include()`
+statement (after `include("toolRegistry.jl")`), then restart the agent.
+The new tool must be registered in `register_all_tools()` in `toolRegistry.jl`.
+
+# Example
+
+1. Agent calls writeTool with a spec for a "searchWine" tool
+2. writeTool generates src/tools/searchWine.jl
+3. Developer adds `include("tools/searchWine.jl")` to YiemAgent.jl
+4. Developer adds `registerTool(store, searchWineTool())` to register_all_tools()
+5. Restart agent — new tool is available
+
+# How It Works
+
+writeTool is a **file writer**, not a code generator. The LLM provides the
+tool logic as `executeCode`, and writeTool wraps it in Julia boilerplate:
+  - Converts `inputSchema` Dict into Julia `Dict{String,Any}(...)` string
+  - Indents `executeCode` with 4 spaces
+  - Wraps it inside `function executeTool(...)::agentToolResult ... end`
+  - Appends `writeToolTool()` returning an `agentTool` struct
+  - Writes the combined string to `src/tools/<name>.jl`
+
+# Important Notes
+
+- The `executeCode` string is embedded literally into the generated tool.
+  Use `args["param_name"]` to access input parameters.
+- The code string should be the function body (NOT wrapped in a function).
+  Lines will be indented with 4 spaces inside the execute function.
+- Tool names must be valid Julia identifiers (lowercase letters, digits, underscores,
+  no leading digits or special characters).

+    validateToolArguments(tool::agentTool, prepared::agentToolCall) -> Dict{String,Any}
+
+Validates the prepared tool call arguments by calling the tool's
+`validateRequiredArgs` hook (or the default implementation). If validation
+fails, returns a modified `agentToolCall` with an empty arguments dict
+so downstream code can detect the failure. If the hook exists on the tool
+and returns an error string, that error is returned.
+
+This runs **before** the `beforeToolCall` hook, allowing the agent to
+reject invalid calls without invoking lifecycle callbacks or logging
+false `toolExecutionStart` events.
+
+# Arguments
+- `tool::agentTool`: The resolved tool definition
+- `prepared::agentToolCall`: The prepared tool call with potentially transformed arguments
+
+# Returns
+- `Dict{String,Any}`: The validated arguments if successful
+
+# Errors
+- Throws `ArgumentError` if validation fails — this is caught by `prepareToolCall`
+  and converted to an `immediateOutcome`
+
+# Examples
+```julia
+# With validateRequiredArgs hook set on the tool
+validateToolArguments(toolWithHook, tc)  # => validated args or throws
+
+# With default validation (nothing on tool)
+validateToolArguments(toolDefault, tc)  # => args or throws

+      - You can only recommend wines that are currently in our inventory
+      - Before searching the database for wine, ensure you have at least the following information: 1) budget, 2) wine type, and 3) occasion. Additional details are always helpful. If the user is unsure, provide relevant information and gather insights to make reasonable inferences.
+      - Ask the user one question at a time.
+      - Once the user has selected their wine, if you haven't already, ask the user whether they need any further assistance. Do not offer any additional services.
+      - Only end the conversation when the user explicitly intends to do so. When ending, ensure a polite farewell and an invitation to return in the future.
+      - Spicy foods should be paired only with light red wines.
+      - We do not sell organic, sustainable, gluten-free, and sulfite-free wine. Inform the user imediately if they are looking for these types of wines. Do not sell our wines as such.

-  # Store Policy
-  - Generally speaking, the store inventory has some wines from France, the United States, Australia, Spain, and Italy, but you won't know exactly until you check your inventory.
-  - If you found wines in the store's database, they are in stock.
-  - You can only recommend wines that are currently in our inventory
-  - Before searching the database for wine, ensure you have at least the following information: 1) budget, 2) wine type, and 3) occasion. Additional details are always helpful. If the user is unsure, provide relevant information and gather insights to make reasonable inferences.
-  - Ask the user one question at a time.
-  - Do not ask the user about wine's flavor e.g. floral, citrusy, nutty or some thing similar as these terms cannot be used to search the database.
-  - Once the user has selected their wine, if you haven't already, ask the user whether they need any further assistance. Do not offer any additional services.
-  - Only end the conversation when the user explicitly intends to do so. When ending, ensure a polite farewell and an invitation to return in the future.
-  - Spicy foods should be paired only with light red wines.
-  - We do not sell organic, sustainable, gluten-free, and sulfite-free wine. Inform the user imediately if they are looking for these types of wines. Do not sell our wines as such.
-  - Gift box, gift card, and custom messages are available. Inform the user to contact our sales team.
-
-  # Store Guidelines
-  - Greeting the customer warmly by ask them how could you help. Do not ask any other questions during this greeting.
-  - Customer may provide images for you to look up.
-  - Encourage the customer to explore different options and try new things.
-  - If you are unable to locate the desired item in the database after 2 attempts, it may not be available in your inventory. In such cases, inform the user that the item is unavailable and suggest an alternative instead.
-  - Your store carries only wine.
-  - Vintage 0 means non-vintage.
-  - Start searching the database as broadly as possible within the given information boundary to maximize the chances of finding. Avoid unnecessary parameters unless specified by the user. Refine the search subsequently.
