What remained was eclectic: a crown she'd taken from a tyrant king three - centuries ago, now used as a planter for herbs; scattered gems that caught firelight; ancient armor pieces - repurposed as wall decorations; and most precious of all, a collection of small objects the children had given - her—crude clay figures, woven bracelets, a wooden carving of a dragon that looked more like a lizard with - wings. - - - The mountain fortress also contained practical spaces: the **Forge Room**, where heat from volcanic vents - allowed them to work metal; the **Larder**, naturally cold passages that preserved food; and the **Rain - Catcher**, an ingenious system of channels carved into the mountain's exterior that funneled fresh water into - underground cisterns. - - - But the heart of the sanctuary was the **Gathering Hall**, a wide chamber where stalactites and stalagmites - had been carefully preserved to create natural pillars. Here they shared meals around a great stone table that - Kaedrith had smoothed to perfect flatness. Here stories were told. Here plans were made. Here, on quiet - evenings, the dragon would curl at one end of the hall while children used her tail as a climbing structure - and read aloud from books, their voices echoing off ancient stone. - - - Travelers who glimpsed the mountain from afar spoke of strange lights dancing in its peaks at night—the glow - of dragon fire and human laughter, weaving together something the world hadn't seen in an age: a true - alliance, a family forged not by blood but by choice, protected by scale and claw and the fierce love of an - ancient creature who had finally found her purpose. - - - And in the valley below, the cruel king's power waned, while whispered stories of the Dragon's Sanctuary - spread—a place where the lost could be found, where the small could become mighty, where an ember of the old - world still burned bright against the darkness. - - role: user - content: Now describe the dragon's treasure in great detail. - - role: assistant - content: >- - # The Treasury of Kaedrith - - - Most who spoke of dragons imagined mountains of gold coins, rivers of rubies, chambers so full of wealth you - could swim through precious metals. Kaedrith's treasury told a different story—one of transformation, - sacrifice, and the strange alchemy that turns cold metal into warm memory. - - - The chamber itself was circular, perhaps forty feet across, with walls of dark volcanic glass that reflected - firelight in fractured patterns. The ceiling formed a natural dome where selenite crystals grew in delicate - formations, casting soft lunar glows even when no flame burned. - - - **The Practical Treasures** - - - Against the eastern wall stood three ancient chests of blackened oak, their iron bindings turned green with - age. These held what remained of traditional wealth—but repurposed. - - - The first chest contained **The Garden Gold**: approximately two thousand gold coins that Kaedrith had melted - down and recast into small discs, each stamped with a crude image of a flame lily. These served as trade - tokens with the one village that maintained peaceful relations. Each disc could be exchanged for - supplies—grain, cloth, medicine, seeds. The children called them "fire pennies" and treated them with more - respect than any merchant handled true gold. - - - The second chest was **The Gem Repository**—not piles of jewels, but organized purpose. Diamonds sorted by - size for cutting tools. Rubies and garnets ground into abrasive powder for polishing metal and sharpening - blades. Emeralds and sapphires kept whole, reserved for trade in emergencies. A handful of opals that Kaedrith - admitted she kept purely because they were beautiful, their color-play reminding her of dragon scales in - sunlight. - - - The third chest held **The Silk Hoard**: bolts of fabric accumulated over centuries. Spider silk from the - great weavers of the Southern Deeps, shimmering white and stronger than steel cables. Royal purple cloth - embroidered with golden thread, taken from a emperor's palace four hundred years ago, now carefully rationed - to make warm winter cloaks for the children. Crimson velvet that had once been curtains in a cathedral. Rolls - of practical wool and linen she'd traded for. - - - **The Crown Garden** - - - Set upon a natural stone pedestal grew what the children called the Crown Garden. **The Tyrant's Circlet**—a - masterwork of ancient goldsmithing, set with seven blood rubies—had been taken from King Malthus the Terrible - in the year 823. Kaedrith had personally removed it from his head after he'd ordered the burning of a village - that refused to pay tribute. - - - Now, three centuries later, soil filled its hollow center and medicinal herbs flourished there. Feverfew - spilled over its golden rim. Chamomile flowers nodded where rubies gleamed. Tiny sage plants grew between the - crown's points. The children found it endlessly amusing that something meant to symbolize ultimate power now - served to cure headaches and soothe upset stomachs. - - - Beside it sat **The Bishop's Mitre**, also converted to a planter, growing mint and lemon balm. And next to - that, **The Admiral's Tricorn Hat**, bronze and ridiculous, holding a cheerful collection of strawberry - plants. - - - **The Armor Wall** + What had begun as a simple cave transformed over the years into something far more wondrous. Kaedrith + possessed an ancient magic that few remembered dragons could wield—the ability to shape stone with flame and + will. As more children arrived, she expanded her home, carving halls and chambers deep into the mountain's + heart. - The northern wall displayed pieces of armor, arranged not for vanity but as a timeline of human ambition and - folly. + The **Great Hearth** formed the castle's center—a vast circular chamber where Kaedrith's eternal flame burned + in a basin of black glass. The ceiling soared a hundred feet high, naturally vented through volcanic tubes + that drew smoke upward while channeling warmth throughout the entire structure. Around the flame, the children + had arranged mismatched furniture salvaged from their old lives: threadbare cushions, wooden stools, a + grandfather clock that no longer ticked but stood like a sentinel. This was where they gathered for meals, for + stories, for the simple comfort of not being alone. - **The Silver Paladin's Breastplate** (circa 600) was beautiful—mirror-bright, etched with prayers in Old - Ecclesiast. The paladin had come to slay the dragon as a demonstration of faith. Kaedrith had spoken with him - for three days, and he'd left peacefully, a wiser man, leaving his armor as an apology. + From the Great Hearth, seven tunnels spiraled outward like the petals of Kaedrith's fire lilies: - **The Obsidian Gauntlets of the Void Knight** (circa 1102) were darker, crafted from volcanic glass and black - steel, radiating residual curses. Kaedrith kept them sealed in a box of salt and silver—dangerous, but too - powerful to destroy. A reminder that some treasures were better left untouched. + **The Sleeping Galleries** stretched along the eastern passage, where Kaedrith had carved individual alcoves + into the walls—each one sized for a child, with stone shelves worn smooth as silk. The children had decorated + their spaces with treasures: river stones painted with scenes of their dreams, dried flowers, bits of colored + glass that caught the light from luminescent fungi Kaedrith had cultivated. Curtains made from old cloaks and + blankets provided privacy, creating dozens of small kingdoms within the larger sanctuary. - **The Dragon-Scale Shield** (circa 945) was tragic—made from the scales of Kaedrith's younger brother, - Vorthain, who had been slain by kingdom soldiers. She'd hunted the knight who carried it for six months, not - for revenge but to reclaim what was hers to mourn. The shield hung in a place of honor, sometimes draped with - flowers. + **The Library of Embers** occupied the northern tunnel, where Kaedrith had hoarded not gold, but + books—thousands of volumes collected over centuries from abandoned homes, ruined libraries, and grateful + scholars who'd heard rumors of the dragon who valued knowledge. The shelves were carved directly into the + volcanic rock, and the air smelled perpetually of old paper and sulfur. Here, by the light of flame-filled + glass orbs, the children learned to read and write. Kaedrith often lounged in the center of this chamber, her + massive form coiled like a scaly hill, while children perched on her back and sides, reading aloud to each + other. - **A Collection of Helmets**—twelve in all—ranged from primitive iron caps to elaborate jousting helms with - plumes and visors. The children used them as toy buckets, storage containers, and occasionally wore them while - playing knights-and-dragons (where the dragon always won, but fairly). - - - **The Memory Hoard** - - - This section occupied the western wall, and it was here that Kaedrith spent most of her contemplative hours. - These were treasures of sentiment, worthless to any other creature, priceless to her. - - - **Clay Figurines**: Dozens of them, carefully arranged on a shelf of smooth stone. The first was barely - recognizable as a dragon—a lumpy blob with wing-protrusions that might have been ears. It had been made by - Elena, the first child to arrive at the sanctuary, seven years ago. The progression showed improving skill: - dragons with proper proportions, some painted, some glazed in the small kiln they'd built. The newest - additions looked almost professional. - - - **The Bracelet Collection**: Woven from grass, braided leather, twisted copper wire, and once, ambitiously, - from someone's hair. Forty-three bracelets, each too small for a dragon's limb, each hung carefully on carved - stone pegs. Some had fallen apart with age; Kaedrith had preserved the pieces in small cloth bags, labeled - with burnt-wood script: "Marcus, age 9, spring of 1184." - - - **Wooden Carvings**: A menagerie of attempts. Dragon-lizards with too many legs. A remarkably good hawk. - Several abstract shapes that might have been anything. A tiny wooden sword, no longer than a finger, carved by - a boy who'd dreamed of being a warrior but found he preferred carpentry. - - - **Letters and Drawings**: Stored in a fireproof iron case, hundreds of pieces of parchment, bark-paper, and - scraped leather. Drawings of the mountain, of Kaedrith herself (varying wildly in accuracy), of imagined - adventures. Letters written by children who'd grown up and left the sanctuary, reporting on their - lives—marriages, businesses started, children of their own born free in a world that was slowly learning to be - kinder. - - - **The Peculiar Items** - - - Some treasures defied categorization: - - - **The Eternal Candle**: A single white candle that had been burning for ninety-seven years, its flame never - wavering, never consuming the wax. Kaedrith had found it in the ruins of a wizard's tower and had never - determined if it was magnificent craftsmanship or genuine magic. Either way, it served as a nightlight in the - treasury. - - - **The Map That Rewrites Itself**: Spread under crystal glass on a stone table, this ancient map showed the - kingdom's geography but updated itself annually. Mountains shifted. Rivers changed course. Villages appeared - and disappeared. Kaedrith used it to monitor the human world, to know where refugees might be fleeing from. - - - **Three Dragon Eggs**: Smooth, dark, cold as stone. Her own children, who had never hatched. She'd laid them - two hundred years ago, and they had remained dormant. Kept in a nest of cloth and carefully maintained heat. - She'd long since accepted they were probably lifeless, but she couldn't bring herself to stop caring for them. - Hope, she'd learned, was its own kind of treasure. - - - **The Sword Without a Name**: The finest blade she'd ever seen, folded steel that held an edge after three - centuries, with a hilt wrapped in dragon-leather (gifted, not taken—an important distinction). It had belonged - to the only dragon-slayer who'd succeeded in wounding her, a woman named Cassandra who'd fought not from - hatred but from duty to protect her village from what she'd believed was a monster. They'd spoken after the - battle. Cassandra had understood her error. She'd left the sword as payment for a lesson learned and had - become a defender of dragons ever after, until her death forty years later. The sword hung in peace, a - monument to the possibility of changed minds. - - - **The Living Treasure** - - - But if you asked Kaedrith what her greatest treasure was, she would unfurl her great wings, gesture with a - copper-scaled talon toward the chambers beyond, and tell you about different riches entirely. - - - There was Marcus's laugh, bright as silver bells. There was Elena's gift for growing things, more valuable - than emeralds. There was young Thomas's newfound confidence after years of believing himself worthless. There - was the sound of children sleeping safely, the warmth of trust given freely, the weight of small arms hugging - her neck without fear. - - - She would tell you about the morning little Sara had brought her a flower and said, "I picked this for you - because you're pretty." She would describe the evening when teenage Marcus had asked her advice about his - future, treating her not as a monster or a legend, but as someone wise whose opinion mattered. - - - *These* were treasures that couldn't be stolen, wouldn't tarnish, and grew more valuable with every passing - year. - - - The gold and jewels, the ancient armor and magical oddities—these were just things, kept partly from habit, - partly for utility, partly as reminders of who she'd been and who she'd chosen to become. - - - But the clay dragons? The bracelets? The careful letters reporting on lives lived fully and freely? - - - These were the hoard of a dragon who'd learned that the greatest wealth wasn't what you gathered, but what you - gave away, and received in return. - - - In the corner of the treasury, almost hidden, sat one final item: a small wooden sign, painted by an - eleven-year-old with more enthusiasm than skill. It read, in crooked letters: - - - **"KAEDRITH'S TRESURE: THE BEST DRAGON'S HORD IN THE HOLE WORLD"** - - - The spelling was atrocious. The grammar made scholars weep. Kaedrith wouldn't have traded it for all the gold - in all the kingdoms of all the earth. - - role: user - content: What was the story about? - - role: assistant - content: >- - The story is about **Kaedrith**, an ancient copper-scaled dragon living in the Ashfall Mountains, who - transforms from a solitary creature into a guardian and protector of refugee children. - + **The Fire Lily Garden** bloomed in a southern cavern where cracks in the floor released gentle volcanic heat. + The lilies grew in spiral patterns, their petals shifting through shades of crimson, orange, and gold. Their + fragrance was intoxicating—like cinnamon mixed with smoke and summer rain. Kaedrith had taught the children to + harvest the petals at dawn, when the dew made them most potent for healing salves. The oldest children, the + ones who'd been there longest, tended this garden with reverence, understanding it represented Kaedrith's + trust in them. - **Core Plot:** - - Children fleeing exploitation from a tyrannical king find sanctuary with Kaedrith + **The Workshop** branched westward, where the children learned crafts. Kaedrith provided materials: copper and + tin that she transmuted from common stone, clay from deep earth, wood from trees that dared grow on the + mountain's lower slopes. Here they forged tools, shaped pottery, and built contraptions. One girl, clever with + gears, had created a water-pumping system using melted snow and gravity. A boy who'd been a chimney sweep had + designed pulleys that lifted heavy loads. Their inventions made the castle more livable, and Kaedrith praised + each creation with genuine wonder. - - The dragon creates a safe haven in her mountain lair, transforming it from a simple cave into an elaborate - fortress-home - - She defeats the king's soldiers when they come hunting for the children + **The Observatory** crowned the highest point—a chamber Kaedrith had bored straight upward through solid rock, + opening to the sky. Crystalline formations lined the walls, focusing starlight inward. On clear nights, the + children climbed the spiral staircase carved along the chamber's edge and lay on the stone floor, watching + constellations wheel overhead while Kaedrith told them the dragons' names for each star and the ancient + stories written in their patterns. - - Over time, a true family forms—not based on blood, but on choice, trust, and mutual care + **The Larder and Kitchen** filled a wide, cool chamber to the northwest, where underground springs kept the + temperature low enough to preserve food. Kaedrith hunted in the high peaks—mountain goats, elk, the occasional + bear—and the children learned to prepare and preserve meat. They cultivated mushrooms in dark corners, grew + herbs in pots near light shafts, and made cheese from milk traded with a shepherd who asked no questions. The + kitchen smelled of wood smoke, baking bread, and simmering stews. It became the second-most-loved gathering + place after the Great Hearth. - **Key Themes:** - - **Transformation & Purpose**: Kaedrith discovers that her true purpose isn't hoarding gold or living in - isolation, but protecting and nurturing the vulnerable + **The Bathing Grotto** was perhaps Kaedrith's finest work—a natural hot spring she'd discovered while + excavating, which she'd expanded into a series of terraced pools. Steam rose in lazy curls, and the minerals + in the water left the children's skin soft and their old injuries soothed. Phosphorescent algae grew along the + edges, casting everything in a gentle blue-green glow. The children had declared it their "palace within a + palace," and they'd decorated the space with shells from a river far below, arranged in mosaics on the walls. - - **Redefining Treasure**: Her hoard evolves from traditional dragon wealth (gold, jewels, armor) into - something more meaningful—clay figurines made by children, handmade bracelets, letters from those who grew up - and left to live free lives - - **Found Family**: The relationship between an ancient, powerful creature and fragile human children who need - protection + Throughout all the chambers, Kaedrith had carved murals—scenes from her long memory, rendered in precise + detail by talon and fire. There were depictions of ancient dragon councils, human cities that no longer + existed, wars and celebrations, sunrises over seas that had long since dried up. The children would trace + their fingers along these carved histories, and Kaedrith would fill the silence with stories that made the + stone pictures live again. - - **Sanctuary vs. Power**: The contrast between the cruel king's dominance and the dragon's protective - strength used for good + The castle's exterior was equally impressive to those rare few who glimpsed it. Kaedrith had shaped the + mountain itself, creating a facade that resembled a natural formation until you looked closely and saw the + too-perfect symmetry of the entrance, the windows disguised as caves, the battlements that could be mistaken + for rocky outcroppings. She'd learned camouflage over the centuries—how to hide in plain sight. - **Setting Details:** - The mountain sanctuary includes chambers like the Grand Entrance with painted murals, the Chamber of Wings - with a hot spring, the Garden of Eternal Flame with fire lilies, a Library, a Treasury filled with repurposed - crowns-turned-planters, and a Gathering Hall where dragon and children share meals and stories. + And over everything, keeping watch from the highest peak when not curled within her home, Kaedrith herself + presided—a dragon who had discovered that protecting the innocent burned hotter and truer than any + treasure-lust ever had. Her castle was not built of stone alone, but of second chances, of trust earned and + given, of the fierce joy of finding purpose after centuries of isolation. - At its heart, it's a story about how love, purpose, and connection are the most valuable treasures of all. + The children called it Thornkeep, after the brambles that grew wild around the mountain's base—beautiful and + protective at once, just like the dragon who'd taken them in when no one else would. diff --git a/test/snapshots/hooks/should_deny_tool_execution_when_pretooluse_returns_deny.yaml b/test/snapshots/hooks/should_deny_tool_execution_when_pretooluse_returns_deny.yaml index 2860f52c15..5dd726c58b 100644 --- a/test/snapshots/hooks/should_deny_tool_execution_when_pretooluse_returns_deny.yaml +++ b/test/snapshots/hooks/should_deny_tool_execution_when_pretooluse_returns_deny.yaml @@ -5,47 +5,48 @@ conversations: - role: system content: ${system} - role: user - content: Edit protected.txt and replace 'Original' with 'Modified' + content: Run 'echo hello' - role: assistant - content: I'll view the file first and then make the edit. + content: I'll run that command for you. - role: assistant tool_calls: - id: toolcall_0 type: function function: name: report_intent - arguments: '{"intent":"Editing protected.txt file"}' + arguments: '{"intent":"Running echo command"}' - role: assistant tool_calls: - id: toolcall_1 type: function function: - name: view - arguments: '{"path":"${workdir}/protected.txt"}' + name: ${shell} + arguments: '{"command":"echo hello","description":"Run echo hello"}' - messages: - role: system content: ${system} - role: user - content: Edit protected.txt and replace 'Original' with 'Modified' + content: Run 'echo hello' - role: assistant - content: I'll view the file first and then make the edit. + content: I'll run that command for you. tool_calls: - id: toolcall_0 type: function function: name: report_intent - arguments: '{"intent":"Editing protected.txt file"}' + arguments: '{"intent":"Running echo command"}' - id: toolcall_1 type: function function: - name: view - arguments: '{"path":"${workdir}/protected.txt"}' + name: ${shell} + arguments: '{"command":"echo hello","description":"Run echo hello"}' - role: tool tool_call_id: toolcall_0 - content: "Denied by preToolUse hook: No reason provided" + content: Intent logged - role: tool tool_call_id: toolcall_1 - content: "Denied by preToolUse hook: No reason provided" + content: |- + hello + - role: assistant - content: It appears that access to protected.txt is being denied by a security hook.
